  • Create form select from object containing values

    - by marks34
    I have such an object : var options = {1: 'Running', 2: 'Falling', 3: 'Collapsing wall', 4: (...)}; I'd like to create form's select element with ooptions taken from this object, so something like that (code I tried which is not working, but you can get the idea) : html = '<form action="" ><select name="block-action"><option>-------</option>'; for(k in obj){ html += '<option value="'+k+'">'+obj[k]+'</option>' } html += '</select></form>'

  • Why is cakephp form input stored in $this->data and POST data stored in $this->params['form'] ?

    - by spudnik1979
    the cakephp rest tutorial says that post data should be in $this-data, but I am finding that it is not, but instead inside $this-params['form'] However, when using cakephp form helper in a view, the data is in $this-data. Am I correct to have to check both locations in my controller? It just seems a bit of a waste of extra code. Shouldnt the data appear in one place for whether it came from a rest rest requestor or Cakephp form post? ps im using cakephp 1.3

  • Change URL Submitted to Depending on Form Selection

    - by Chris
    I have a form which I need to submit to one of three different URLs depending on a selection made in the form. I suspect the easiest solution is to use jQuery to insert the appropriate path before the rest of the form parameters as the selection is made, but not sure on what the code would be. Any pointers greratly appreciated! <form id="myForm" action='/booking/default-path' accept-charset='utf-8' method='get'> <select name="paramA" id="paramA"> <option id="optionA" value="A" selected="selected">Option A</option> <option id="optionB" value="B">Option B</option> </select> <select name="currency" id="currency"> <option id="GBP" value="GBP" selected="selected">British Pounds</option> <option id="EUR" value="EUR">Euros</option> <option id="USD" value="USD">US Dollars</option> </select> <input type="submit" value="submit" id="submit" name="submit" /> </form> Where the three different URLs would be: ../booking/default-path-gbp?...[params here]... ../booking/default-path-eur?...[params here]... ../booking/default-path-usd?...[params here]... I know it would be a lot easier to incorporate the parameter in the usual way and just use one submission URL root, but unfortunately I'm submitting to an eComms system out of my control and am stuck with having to find a solution to this. Should be easy I think, but not sure where to start, jQuery used elsewhere, so would prefer to use this framework in any solutions.

  • jQuery slider onChange auto submit form

    - by bikey77
    I'm using a jQuery slider as a price range selector in a form. I'd like to have the form submit automatically when one of the values has been changed. I used a couple of examples I found on SO but they didn't work with my code. <form action="itemlist.php" method="post" enctype="application/x-www-form-urlencoded" name="priceform" id="priceform" target="_self"> <div id="slider-holder"> Prices: From <span id="pricefromlabel">100 &#8364;</span> To <span id="pricetolabel">500 &#8364;</span> <input type="hidden" id="pricefrom" name="pricefrom" value="100" /> <input type="hidden" id="priceto" name="priceto" value="500" /> <div id="slider-range"></div> <input name="Search" type="submit" value="Search" /> </div> </form> This is the code that displays the values of the slider and updates 2 hidden form fields I use to store the prices in order to submit: <script> $(function() { $("#slider-range" ).slider({ range: true, min: 0, max: 1000, values: [ <?=$minprice?>, <?=$maxprice?> ], start: function (event, ui) { event.stopPropagation(); }, slide: function( event, ui ) { $( "#pricefrom" ).val(ui.values[0]); $( "#priceto" ).val(ui.values[1]); $( "#pricefromlabel" ).html(ui.values[0] + ' &euro;'); $( "#pricetolabel" ).html(ui.values[1] + ' &euro;'); } }); return false; }); </script> I've tried adding this code as well as an data-autosubmit="true" attribute to the div but no result. $(function() { $('[data-autosubmit="true"]').change(function() { parentForm = $(this).('#priceform'); clearTimeout(submitTimeout); submitTimeout = setTimeout(function() { parentForm.submit() }, 100); }); I've also tried adding a $.post() event to the slider but I'm not very good with jQuery so I'm probably doing it wrong. Any help will be appreciated.

  • Submitting form in php file accessed by Ajax?

    - by dronnoc
    Hi people, I am trying to figure out how to submit a form in a page being accessed by Ajax? here are some code snippets to help demonstrate what i am trying to say. HTML BODY - THIS IS WHAT THE USER WILL SEE. <html> <head> <script language="javascript" src="linktoajaxfile.js"> </head> <body onLoad="gotoPage(0)"> <div id="fillThis"> </div> </body> </html> AJAX FILE var xmlhttp function gotoPage(phase) { xmlhttp=GetXmlHttpObject(); if (xmlhttp==null) { alert ("Your browser does not support AJAX!"); return; } var url="pageofstuffce.php"; url=url+"?stg="+phase; url=url+"&sid="+Math.random(); xmlhttp.onreadystatechange=stateChanged; xmlhttp.open("GET",url,true); xmlhttp.send(null); } function stateChanged() { if (xmlhttp.readyState==4) { document.getElementById("fillThis").innerHTML=xmlhttp.responseText; } } function GetXmlHttpObject() { if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari return new XMLHttpRequest(); } if (window.ActiveXObject) { // code for IE6, IE5 return new ActiveXObject("Microsoft.XMLHTTP"); } return null; } PAGE OF DATA <?php $stage = $_GET['stg']; if($stage == 0) { echo '<a onClick="gotoPage(1)">click me</a>'; } elseif($stage == 1) { <form> <input type="text" name="name"> <input type="submit" name="submit"> </form> } elseif(somehow can reach here) { show data from form. } ?> Can anyone perhaps help me get past the form and display the data in the same page? Also, i have looked around, and i don't think anything around has what i need... correct me if i'm wrong though :) Thanks in advance, and i hope i didn't put in too much detail :) Dronnoc EDIT Forgot to mention what I've tried; I have tried submitting the form to itself (same file) and that destroyed the ajax link, and opened the page. i have also tried just having the button move the page onto another step, but the $_POST variable is empty... i am at a loss, so does anyone else have any ideas?

  • CodeIgniter Form Validaton + JS. Form re-population.

    - by solefald
    Hello. I have a from with a checkbox, and depending on the checkbox state 2 different divs are shown. var alias = document.getElementById('alias'); var list = document.getElementById('list'); if(document.getElementById('isList').checked) { alias.style.display = 'none'; list.style.display = 'table-row'; } else { alias.style.display = 'table-row'; list.style.display = 'none'; } Here is the HTML/PHP (relevant) part: <tr id="alias" style="display:table-row;"> <td>' . form_label('Destination:', 'destination') . '</td> <td>' . form_textarea('destination') . '</td> </tr> <tr id="list" style="display:none;"> <td>' . form_label('File Path:', 'list_path') . '</td> <td>' . form_input('list_path') . '</td> </tr> alias div is shown by default on page load, list shown then i click on isList checkbox, and alias is shown again when i click on the checkbox again. This part works great and pretty straight froward. Now, I add CodeIgniter Form Validation plugin, set appropriate rules and set-up validation plugin to re-populate the form with. Without checkbox enabled everything works great. On errors form is re-populated. However, when form is submitted with checkbox enabled, I have an issue. CI's Form Validation plugin re-populates the form, and re-enables the checkbox, but the list div that is supposed to be shown when checkbox enabled is not there, and instead the alias div is shown. Is there any way around this issue? Can i have the list div shown on list validation error? Also, i would like to avoid using JavaScript form validation, and stick with my good old PHP. Thank you in advance. -i

  • Upload to PPA succeeded but packages doesn't appear

    - by lorin
    I'm trying to upload packages to my PPA for the first time. I want to use the PPA for customized versions of the OpenStack Compute (nova) project, so I tried to do a test by uploading packages corresponding to the bexar release of this project (lp:nova/bexar), with a new version number and changelog entry.

  • HTML5 Form Validation

    - by Stephen.Walther
    The latest versions of Google Chrome (16+), Mozilla Firefox (8+), and Internet Explorer (10+) all support HTML5 client-side validation. It is time to take HTML5 validation seriously. The purpose of the blog post is to describe how you can take advantage of HTML5 client-side validation regardless of the type of application that you are building. You learn how to use the HTML5 validation attributes, how to perform custom validation using the JavaScript validation constraint API, and how to simulate HTML5 validation on older browsers by taking advantage of a jQuery plugin. Finally, we discuss the security issues related to using client-side validation. Using Client-Side Validation Attributes The HTML5 specification discusses several attributes which you can use with INPUT elements to perform client-side validation including the required, pattern, min, max, step, and maxlength attributes. For example, you use the required attribute to require a user to enter a value for an INPUT element. The following form demonstrates how you can make the firstName and lastName form fields required: <!DOCTYPE html> <html > <head> <title>Required Demo</title> </head> <body> <form> <label> First Name: <input required title="First Name is Required!" /> </label> <label> Last Name: <input required title="Last Name is Required!" /> </label> <button>Register</button> </form> </body> </html> If you attempt to submit this form without entering a value for firstName or lastName then you get the validation error message: Notice that the value of the title attribute is used to display the validation error message “First Name is Required!”. The title attribute does not work this way with the current version of Firefox. If you want to display a custom validation error message with Firefox then you need to include an x-moz-errormessage attribute like this: <input required title="First Name is Required!" x-moz-errormessage="First Name is Required!" /> The pattern attribute enables you to validate the value of an INPUT element against a regular expression. For example, the following form includes a social security number field which includes a pattern attribute: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Pattern</title> </head> <body> <form> <label> Social Security Number: <input required pattern="^d{3}-d{2}-d{4}$" title="###-##-####" /> </label> <button>Register</button> </form> </body> </html> The regular expression in the form above requires the social security number to match the pattern ###-##-####: Notice that the input field includes both a pattern and a required validation attribute. If you don’t enter a value then the regular expression is never triggered. You need to include the required attribute to force a user to enter a value and cause the value to be validated against the regular expression. Custom Validation You can take advantage of the HTML5 constraint validation API to perform custom validation. You can perform any custom validation that you need. The only requirement is that you write a JavaScript function. For example, when booking a hotel room, you might want to validate that the Arrival Date is in the future instead of the past: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Constraint Validation API</title> </head> <body> <form> <label> Arrival Date: <input id="arrivalDate" type="date" required /> </label> <button>Submit Reservation</button> </form> <script type="text/javascript"> var arrivalDate = document.getElementById("arrivalDate"); arrivalDate.addEventListener("input", function() { var value = new Date(arrivalDate.value); if (value < new Date()) { arrivalDate.setCustomValidity("Arrival date must be after now!"); } else { arrivalDate.setCustomValidity(""); } }); </script> </body> </html> The form above contains an input field named arrivalDate. Entering a value into the arrivalDate field triggers the input event. The JavaScript code adds an event listener for the input event and checks whether the date entered is greater than the current date. If validation fails then the validation error message “Arrival date must be after now!” is assigned to the arrivalDate input field by calling the setCustomValidity() method of the validation constraint API. Otherwise, the validation error message is cleared by calling setCustomValidity() with an empty string. HTML5 Validation and Older Browsers But what about older browsers? For example, what about Apple Safari and versions of Microsoft Internet Explorer older than Internet Explorer 10? What the world really needs is a jQuery plugin which provides backwards compatibility for the HTML5 validation attributes. If a browser supports the HTML5 validation attributes then the plugin would do nothing. Otherwise, the plugin would add support for the attributes. Unfortunately, as far as I know, this plugin does not exist. I have not been able to find any plugin which supports both the required and pattern attributes for older browsers, but does not get in the way of these attributes in the case of newer browsers. There are several jQuery plugins which provide partial support for the HTML5 validation attributes including: · jQuery Validation — http://docs.jquery.com/Plugins/Validation · html5Form — http://www.matiasmancini.com.ar/jquery-plugin-ajax-form-validation-html5.html · h5Validate — http://ericleads.com/h5validate/ The jQuery Validation plugin – the most popular JavaScript validation library – supports the HTML5 required attribute, but it does not support the HTML5 pattern attribute. Likewise, the html5Form plugin does not support the pattern attribute. The h5Validate plugin provides the best support for the HTML5 validation attributes. The following page illustrates how this plugin supports both the required and pattern attributes: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>h5Validate</title> <style type="text/css"> .validationError { border: solid 2px red; } .validationValid { border: solid 2px green; } </style> </head> <body> <form id="customerForm"> <label> First Name: <input id="firstName" required /> </label> <label> Social Security Number: <input id="ssn" required pattern="^d{3}-d{2}-d{4}$" title="Expected pattern is ###-##-####" /> </label> <input type="submit" /> </form> <script type="text/javascript" src="Scripts/jquery-1.4.4.min.js"></script> <script type="text/javascript" src="Scripts/jquery.h5validate.js"></script> <script type="text/javascript"> // Enable h5Validate plugin $("#customerForm").h5Validate({ errorClass: "validationError", validClass: "validationValid" }); // Prevent form submission when errors $("#customerForm").submit(function (evt) { if ($("#customerForm").h5Validate("allValid") === false) { evt.preventDefault(); } }); </script> </body> </html> When an input field fails validation, the validationError CSS class is applied to the field and the field appears with a red border. When an input field passes validation, the validationValid CSS class is applied to the field and the field appears with a green border. From the perspective of HTML5 validation, the h5Validate plugin is the best of the plugins. It adds support for the required and pattern attributes to browsers which do not natively support these attributes such as IE9. However, this plugin does not include everything in my wish list for a perfect HTML5 validation plugin. Here’s my wish list for the perfect back compat HTML5 validation plugin: 1. The plugin would disable itself when used with a browser which natively supports HTML5 validation attributes. The plugin should not be too greedy – it should not handle validation when a browser could do the work itself. 2. The plugin should simulate the same user interface for displaying validation error messages as the user interface displayed by browsers which natively support HTML5 validation. Chrome, Firefox, and Internet Explorer all display validation errors in a popup. The perfect plugin would also display a popup. 3. Finally, the plugin would add support for the setCustomValidity() method and the other methods of the HTML5 validation constraint API. That way, you could implement custom validation in a standards compatible way and you would know that it worked across all browsers both old and new. Security It would be irresponsible of me to end this blog post without mentioning the issue of security. It is important to remember that any client-side validation — including HTML5 validation — can be bypassed. You should use client-side validation with the intention to create a better user experience. Client validation is great for providing a user with immediate feedback when the user is in the process of completing a form. However, client-side validation cannot prevent an evil hacker from submitting unexpected form data to your web server. You should always enforce your validation rules on the server. The only way to ensure that a required field has a value is to verify that the required field has a value on the server. The HTML5 required attribute does not guarantee anything. Summary The goal of this blog post was to describe the support for validation contained in the HTML5 standard. You learned how to use both the required and the pattern attributes in an HTML5 form. We also discussed how you can implement custom validation by taking advantage of the setCustomValidity() method. Finally, I discussed the available jQuery plugins for adding support for the HTM5 validation attributes to older browsers. Unfortunately, I am unaware of any jQuery plugin which provides a perfect solution to the problem of backwards compatibility.

Entering a value into the arrivalDate field triggers the input event. The JavaScript code adds an event listener for the input event and checks whether the date entered is greater than the current date. If validation fails then the validation error message “Arrival date must be after now!” is assigned to the arrivalDate input field by calling the setCustomValidity() method of the validation constraint API. Otherwise, the validation error message is cleared by calling setCustomValidity() with an empty string. HTML5 Validation and Older Browsers But what about older browsers? For example, what about Apple Safari and versions of Microsoft Internet Explorer older than Internet Explorer 10? What the world really needs is a jQuery plugin which provides backwards compatibility for the HTML5 validation attributes. If a browser supports the HTML5 validation attributes then the plugin would do nothing. Otherwise, the plugin would add support for the attributes. Unfortunately, as far as I know, this plugin does not exist. I have not been able to find any plugin which supports both the required and pattern attributes for older browsers, but does not get in the way of these attributes in the case of newer browsers. There are several jQuery plugins which provide partial support for the HTML5 validation attributes including: · jQuery Validation — http://docs.jquery.com/Plugins/Validation · html5Form — http://www.matiasmancini.com.ar/jquery-plugin-ajax-form-validation-html5.html · h5Validate — http://ericleads.com/h5validate/ The jQuery Validation plugin – the most popular JavaScript validation library – supports the HTML5 required attribute, but it does not support the HTML5 pattern attribute. Likewise, the html5Form plugin does not support the pattern attribute. The h5Validate plugin provides the best support for the HTML5 validation attributes. The following page illustrates how this plugin supports both the required and pattern attributes: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>h5Validate</title> <style type="text/css"> .validationError { border: solid 2px red; } .validationValid { border: solid 2px green; } </style> </head> <body> <form id="customerForm"> <label> First Name: <input id="firstName" required /> </label> <label> Social Security Number: <input id="ssn" required pattern="^\d{3}-\d{2}-\d{4}$" title="Expected pattern is ###-##-####" /> </label> <input type="submit" /> </form> <script type="text/javascript" src="Scripts/jquery-1.4.4.min.js"></script> <script type="text/javascript" src="Scripts/jquery.h5validate.js"></script> <script type="text/javascript"> // Enable h5Validate plugin $("#customerForm").h5Validate({ errorClass: "validationError", validClass: "validationValid" }); // Prevent form submission when errors $("#customerForm").submit(function (evt) { if ($("#customerForm").h5Validate("allValid") === false) { evt.preventDefault(); } }); </script> </body> </html> When an input field fails validation, the validationError CSS class is applied to the field and the field appears with a red border. When an input field passes validation, the validationValid CSS class is applied to the field and the field appears with a green border. From the perspective of HTML5 validation, the h5Validate plugin is the best of the plugins. It adds support for the required and pattern attributes to browsers which do not natively support these attributes such as IE9. However, this plugin does not include everything in my wish list for a perfect HTML5 validation plugin. Here’s my wish list for the perfect back compat HTML5 validation plugin: 1. The plugin would disable itself when used with a browser which natively supports HTML5 validation attributes. The plugin should not be too greedy – it should not handle validation when a browser could do the work itself. 2. The plugin should simulate the same user interface for displaying validation error messages as the user interface displayed by browsers which natively support HTML5 validation. Chrome, Firefox, and Internet Explorer all display validation errors in a popup. The perfect plugin would also display a popup. 3. Finally, the plugin would add support for the setCustomValidity() method and the other methods of the HTML5 validation constraint API. That way, you could implement custom validation in a standards compatible way and you would know that it worked across all browsers both old and new. Security It would be irresponsible of me to end this blog post without mentioning the issue of security. It is important to remember that any client-side validation — including HTML5 validation — can be bypassed. You should use client-side validation with the intention to create a better user experience. Client validation is great for providing a user with immediate feedback when the user is in the process of completing a form. However, client-side validation cannot prevent an evil hacker from submitting unexpected form data to your web server. You should always enforce your validation rules on the server. The only way to ensure that a required field has a value is to verify that the required field has a value on the server. The HTML5 required attribute does not guarantee anything. Summary The goal of this blog post was to describe the support for validation contained in the HTML5 standard. You learned how to use both the required and the pattern attributes in an HTML5 form. We also discussed how you can implement custom validation by taking advantage of the setCustomValidity() method. Finally, I discussed the available jQuery plugins for adding support for the HTM5 validation attributes to older browsers. Unfortunately, I am unaware of any jQuery plugin which provides a perfect solution to the problem of backwards compatibility.

    - by Keyo
    I am trying to upload two files at once (two file fields) with codeigniters upload class. Despite having provided the field name codeigniter produces errors on the second field. I this a limitation of codeigniter, php or html or am I simply using the class incorectly? $this->upload->do_upload('video_file') $this->upload->do_upload('image_file') Produces this on the image field: The filetype you are attempting to upload is not allowed. Here are my two functions function upload_image() { $thumb_size = 94; $config['upload_path'] = './assets/uploads/images/'; $config['allowed_types'] = 'jpg|png|gif'; $config['max_size'] = '2048'; $config['file_name'] = 'video_' . rand(999999, 999999999); $this->load->library('upload', $config); if (!$this->upload->do_upload('image_file')) { $error = array('error' => $this->upload->display_errors()); return $error; } else { function upload_video() { $config['upload_path'] = './assets/uploads/videos/'; $config['allowed_types'] = 'flv'; $config['max_size'] = '0'; $config['file_name'] = 'video_' . rand(999999, 999999999); $this->load->library('upload', $config); if (!$this->upload->do_upload('video_file')) { $error = array('error' => $this->upload->display_errors()); return $error; } else {

  • Zend Framework problems using Element, sub-forms and belongsTo

    Still pulling my hair out with Zend_Form and any elements that need to be placed in a sub-array. form-populate() does not work when working with elements within a sub-form that have been set to a parent array using belongsTo() - I think it is actually a bug in Zend_Form-setDefaults() but just wanted to see if anyone else has a) had the same problem and b) managed to work around it...

  • How do I use ViewScripts on Zend_Form File Elements?

    - by Sonny
    I am using this ViewScript for my standard form elements: <div class="field" id="field_<?php echo $this->element->getId(); ?>"> <?php if (0 < strlen($this->element->getLabel())) : ?> <?php echo $this->formLabel($this->element->getName(), $this->element->getLabel());?> <?php endif; ?> <span class="value"><?php echo $this->{$this->element->helper}( $this->element->getName(), $this->element->getValue(), $this->element->getAttribs() ) ?></span> <?php if (0 < $this->element->getMessages()->length) : ?> <?php echo $this->formErrors($this->element->getMessages()); ?> <?php endif; ?> <?php if (0 < strlen($this->element->getDescription())) : ?> <span class="hint"><?php echo $this->element->getDescription(); ?></span> <?php endif; ?> </div> Trying to use that ViewScript alone results in an error: Exception caught by form: No file decorator found... unable to render file element Looking at this FAQ revealed part of my problem, and I updated my form element decorators like this: 'decorators' => array( array('File'), array('ViewScript', array('viewScript' => 'form/field.phtml')) ) Now it's rendering the file element twice, once within my view script, and extra elements with the file element outside my view script: <input type="hidden" name="MAX_FILE_SIZE" value="8388608" id="MAX_FILE_SIZE" /> <input type="hidden" name="UPLOAD_IDENTIFIER" value="4b5f7335a55ee" id="progress_key" /> <input type="file" name="upload_file" id="upload_file" /> <div class="field" id="field_upload_file"> <label for="upload_file">Upload File</label> <span class="value"><input type="file" name="upload_file" id="upload_file" /></span> </div> Any ideas on how to handle this properly with a ViewScript?

  • piecing together a jquery form mailer

    - by Joel
    Hi guys, My newbieness is shining through here...I managed to piece together a form mailer that works great, but now I need to add two more fields, and I'm at a loss as to how to do it. Over the months, I have commented out some things I didn't need, but now I'm stuck. I borrowed from this tutorial to make the original form: http://trevordavis.net/blog/tutorial/ajax-forms-with-jquery/ But then I cannibalized it to make an email signup form for a newsletter, so the fields I need are: recipient email (me-hard coded in) senders email address subject (hardcoded in) first name and city in the body of the message For my form, I have this: <div> <?php include('verify.php'); ?> <form action="index_success.php" method="post" id="sendEmail" class="email"> <h3 class="register2">Newsletter Signup:</h3> <ul class="forms email"> <li class="name"><label for="yourName">Name: </label> <input type="text" name="yourName" class="info" id="yourName" value=" " /><br> </li> <li class="city"><label for="yourCity">City: </label> <input type="text" name="yourCity" class="info" id="yourCity" value=" " /><br> </li> <li class="email"><label for="emailFrom">Email: </label> <input type="text" name="emailFrom" class="info" id="emailFrom" value="<?= $_POST['emailFrom']; ?>" /> <?php if(isset($emailFromError)) echo '<span class="error">'.$emailFromError.'</span>'; ?> </li> <li class="buttons email"> <button type="submit" id="submit">Send</button> <input type="hidden" name="submitted" id="submitted" value="true" /> </li> </ul> </form> </div> emailcontact.js: $(document).ready(function(){ $("#submit").click(function(){ $(".error").hide(); var hasError = false; var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/; var emailFromVal = $("#emailFrom").val(); if(emailFromVal == '') { $("#emailFrom").after('<span class="error">You forgot to enter the email address to send from.</span>'); hasError = true; } else if(!emailReg.test(emailFromVal)) { $("#emailFrom").after('<span class="error">Enter a valid email address to send from.</span>'); hasError = true; } var subjectVal = $("#subject").val(); if(subjectVal == '') { $("#subject").after('<span class="error">You forgot to enter your name.</span>'); hasError = true; } var messageVal = $("#message").val(); if(messageVal == '') { $("#message").after('<span class="error">You forgot to enter your city.</span>'); hasError = true; } if(hasError == false) { $(this).hide(); $("#sendEmail li.buttons").append('<img src="/wp-content/themes/default/images/template/loading.gif" alt="Loading" id="loading" />'); $.post("/includes/sendemail.php", //emailTo: emailToVal, { emailFrom: emailFromVal, subject: subjectVal, message: messageVal }, function(data){ $("#sendEmail").slideUp("normal", function() { $("#sendEmail").before('<h3 class="register2">Success!</h3><p class="emailbox">You are on the Newsletter email list.</p>'); }); } ); } return false; }); }); sendmail.php: <?php $mailTo = $_POST['emailTo']; $mailFrom = $_POST['emailFrom']; $subject = $_POST['yourName']; $message = $_POST['yourCity']; mail('[email protected]','Rattletree Newsletter', 'Name='.$subject.

  • Reading file data during form's clean method

    - by Dominic Rodger
    So, I'm working on implementing the answer to my previous question. Here's my model: class Talk(models.Model): title = models.CharField(max_length=200) mp3 = models.FileField(upload_to = u'talks/', max_length=200) Here's my form: class TalkForm(forms.ModelForm): def clean(self): super(TalkForm, self).clean() cleaned_data = self.cleaned_data if u'mp3' in self.files: from mutagen.mp3 import MP3 if hasattr(self.files['mp3'], 'temporary_file_path'): audio = MP3(self.files['mp3'].temporary_file_path()) else: # What goes here? audio = None # setting to None for now ... return cleaned_data class Meta: model = Talk Mutagen needs file-like objects - the first case (where the uploaded file is larger than the size of file handled in memory) works fine, but I don't know how to handle InMemoryUploadedFile that I get otherwise. I've tried: # TypeError (coercing to Unicode: need string or buffer, InMemoryUploadedFile found) audio = MP3(self.files['mp3']) # TypeError (coercing to Unicode: need string or buffer, cStringIO.StringO found) audio = MP3(self.files['mp3'].file) # Hangs seemingly indefinitely audio = MP3(self.files['mp3'].file.read()) Is there something wrong with mutagen, or am I doing it wrong?

  • Form inside a hidden div has no values on post

    - by Mick
    I have a html form that posts to a new page on submit. If required a user can click a button to make a small table visible in a div box. this adds more text input fields to my form. The problem is, regardless of the div box being hidden or visible none of the additional fields data is sent when the form is posted . the div box code function quotevisi() { document.getElementById("quote").style.visibility = "visible"; tdat = "" ; tdat += "<h2 align='center' >Client Quotation </h2>" ; tdat += "<table align='center'cellpadding='1' width='690px'><tr>" tdat += "<td ></td><td>Additional 1</td>" ; tdat += "<td ><label><textarea id='line1' cols='50' rows='1'>" tdat += "</textarea></label></td></tr>" tdat += "<td ></td><td >Additional 2 </td>" ; tdat += "<td ><label><textarea id='line2' name='line2' cols='50' rows='1'>" tdat += "</textarea></label></td></tr>" tdat += "<td ></td><td >Additional 3 </td>" ; tdat += "<td ><label><textarea id='line3' name='line3' cols='50' rows='1'>" tdat += "</textarea></label></td></tr>" tdat += "<td ></td><td >Special Instructions</td>" ; tdat += "<td ><label><textarea id='special' name='special' cols='50' rows='1'>" tdat += "</textarea></label></td></tr>" tdat += "<td ></td><td ></td> <td>" ; tdat += "<input type='button' value='View Quote' onclick='view_quote()' /> " tdat += "<input type='button' value='Close' onclick='closequote()' /> " tdat += "<td ></td> " ; tdat += "</table> " // display in the quote div (style sheet) document.getElementById('quote').innerHTML= tdat } The form is a bit big to but the button for the hidden field is this <td ><input class="buttn" type="button" value="Extra Quote details " onclick="quotevisi();" /> </td> I would of thought that all this information would go with the form on post . But it doesent. Oh finally the div box code is placed after this line <form style='background-color:ccc' id='form1' name='form1' method='post' action='process.php' > Any help or thoughts would be much appreciated thanks Mick

  • how do I upload photos from shotwell?

    - by Mags
    I only started using Ubuntu a couple months ago. I've been able to get pictures from my camera onto the machine. The system is very different for me and I'm trying to work it out on my own, but I have a homework assignment that requires me to upload JPG files of photos I take and I'm having a problem. When I click the button on the page to choose a file, I go into the different photo files and nothing shows up, but the screen where files would be turns a very faint orange, just a tint. I've tried putting the named photos on my desktop, but the upload screen doesn't recognize it at all. How can I use this software to upload my pictures? Thanks.
