  • form validation without reset

    - by Paulo Bueno
    Hi guys Is there a way to check the data sent by a form to a PHP page return to the form page WITHOUT resetting the data sent and show a error? The form has 20 fields and I need to check one of them on a bd. If it fails the user may be redirected to the form page with the form populated and displaying a error message on the field which is 'wrong'. I would like any advice of a technique instead of populating each field using PHP.

  • Rails validation issue with before_validation

    - by Chance
    I'm still fairly new to rails so I'm not sure what I'm missing here. I'm using GeoKit to geocode an address upon saving. I have a method that geocodes an address and if it fails to find it, it adds an error to the errors list. I've tested it in the console and it is failing on the geocode (presumably adding the error) but still saving successfully. acts_as_mappable before_validation_on_create :geocode_address before_validation_on_update :geocode_address validates_presence_of :street validates_presence_of :city validates_presence_of :state validates_presence_of :zip validates_presence_of :name validates_uniqueness_of :name def geocode_address geo=Geokit::Geocoders::MultiGeocoder.geocode ("#{street}, #{city}, #{state}, #{zip}") puts "geocoded: #{street}, #{city}, #{state}, #{zip}" if geo.success self.lat, self.lng = geo.lat,geo.lng else errors.add(:street, "Could not Geocode address") end puts "geo status: #{geo.success}" end Any help would be greatly appreciated, thanks :)

  • Javascript Code For HTML5 Form Validation Not Working

    - by MistUnleashed
    I'm new to JavaScript so I have no idea why this code does not work and validate my HTML5 Form like it should. The JavaScript code which can be found below is supposed to check if the browser supports the required attribute and if it doesn't then it will validate the form and check for any empty spaces. I got the code from this website. In the body of the webpage containing my form I have this: Below is the contactvalidate.js file: $('#formTemplate').submit(function() { if (!attributeSupported("required") || ($.browser.safari)) { $("#formTemplate [required]").each(function(index) { if (!$(this).val()) { alert("Please fill all required fields."); return false; } }); } return false; }); Do I need to change anything in this code or should it work? As I've said I'm new to JavaScript so any help you guys could give me is greatly appreciated.

  • A comprehensive regex for phone number validation

    - by Nicholas Trandem
    I'm trying to put together a comprehensive regex to validate phone numbers. Ideally it would handle international formats, but it must handle US formats, including the following: 1-234-567-8901 1-234-567-8901 x1234 1-234-567-8901 ext1234 1 (234) 567-8901 1.234.567.8901 1/234/567/8901 12345678901 I'll answer with my current attempt, but I'm hoping somebody has something better and/or more elegant.

  • PHP & form validation

    - by user887515
    I have a form that I'm submitting via ajax, and I want to return a message of the list of fields that were empty. I've got that all done and dusted, but it just seems really long winded on the PHP side of things. How can I do the below in a less convoluted way? <?php if(empty($_POST["emailaddress"])){ $error = 'true'; $validation_msg = 'Country missing.'; if(empty($error_msg)){ $error_msg .= $validation_msg; } else{ $error_msg .= '\n' . $validation_msg; } } if(empty($_POST["password"])){ $error = 'true'; $validation_msg = 'Country missing.'; if(empty($error_msg)){ $error_msg .= $validation_msg; } else{ $error_msg .= '\n' . $validation_msg; } } if(empty($_POST["firstname"])){ $error = 'true'; $validation_msg = 'First name missing.'; if(empty($error_msg)){ $error_msg .= $validation_msg; } else{ $error_msg .= '\n' . $validation_msg; } } if(empty($_POST["lastname"])){ $error = 'true'; $validation_msg = 'Last name missing.'; if(empty($error_msg)){ $error_msg .= $validation_msg; } else{ $error_msg .= '\n' . $validation_msg; } } if($error){ header('HTTP/1.1 500 Internal Server Error'); header('Content-Type: application/json'); die($error_msg); } ?>

  • Data types for validation

    - by nevalu
    How to create a new data type which to can check/validate its schema when is created a new variable (of that type)? By example, to validate if a string has 20 characters, I tried: {{{ // Format: 2006-01-12T06:06:06Z func date(str string) { if len(str) != 20 { fmt.Println("error") } } var Date = date() type Account struct { domain string username string created Date } }}} but it faills because Date is not a type.

  • asp.net multiple textbox validation

    - by Zaps
    Hi, I currently have 3 textbox controls on my page. I also have a required valdiator of each of the textboxes. However I only want the validator for a textbox to fire if there is text in either of the other 2 textboxes. If all 3 textboxes are empty then no validators should fire. Is there any way I can do this in javascript/jquery as I want the user to get the best experience possible. Any help would be greatly appreciated. Thanks in advance.

  • Can I improve my validation?

    - by Qmal
    So I want to validate my form using jQuery, this is how I imagine it and it works, but is the best method of doing it and maybe I can do it more effective with less code? <script type="text/javascript"> $(document).ready(function() { $("#frmCatAdd").submit(function() { var name = $("#edtName").val(); if (name == "") $("#edtName").css("border", "1px solid red") else $("#frmCatAdd").submit(); return false; }); }); </script>

  • Customise Validation summary

    - by cpoDesign
    I have used html.ValidationSummary to get all errors displayed on top of the page. This will render list with errors on top of the page. Example: <ul> <li>UserName is invalid</li> </ul> I have how ever need to render every item instead of list as custom div with additional html tags inside. such as short example below: <div> <div class="right"><a href="#closeError">Close error</div> <div class="right"><a href="#Update">Update Field</div> <label>Error:</label> Name on the page is invalid. </div> What is your opininon how to achieve this rendering? I have considered to create html helper where i will take ModelState and get all errors, but not sure this will work...

  • How do you write Valid XHTML 1.0 Strict code when you are using javascript to fill an element that r

    - by Tim Visher
    I'm running my site through the W3C's validator trying to get it to validate as XHTML 1.0 Strict and I've gotten down to a particularly sticky (at least in my experience) validation error. I'm including certain badges from various services in the site that provide their own API and code for inclusion on an external site. These badges use javascript (for the most part) to fill an element that you insert in the markup which requires a child. This means that in the end, perfectly valid markup is generated, but to the validator, all it sees is an incomplete parent-child tag which it then throws an error on. As a caveat, I understand that I could complain to the services that their badges don't validate. Sans this, I assume that someone has validated their code while including badges like this, and that's what I'm interested in. Answers such as, 'Complain to Flickr about their badge' aren't going to help me much. An additional caveat: I would prefer that as much as possible the markup remains semantic. I.E. Adding an empty li tag or tr-td pair to make it validate would be an undesirable solution, even though it may be necessary. If that's the only way it can be made to validate, oh well, but please lean answers towards semantic markup. As an example: <div id="twitter_div"> <h2><a href="http://twitter.com/stopsineman">@Twitter</a></h2> <ul id="twitter_update_list"> <script type="text/javascript" src="http://twitter.com/javascripts/blogger.js"></script> <script type="text/javascript" src="http://twitter.com/statuses/user_timeline/stopsineman.json?callback=twitterCallback2&amp;count=1"></script> </ul> </div> Notice the ul tags wrapping the javascript. This eventually gets filled in with lis via the script, but to the validator it only sees the unpopulated ul. Thanks in advance!

  • A potentially dangerous Request.Form value was detected: Dealing with these errors proactively, or a

    - by Albert
    I'm noticing this error more and more in my error logs. I've read through the questions here talking about this error, but they don't address what I would like to do (see below). I'm considering three options, in the order of preference: 1) When submitting a form (I use formviews almost exclusively, if that helps), if potentially dangerous characters are detected, automatically strip them out and submit. 2) When submitting a form, if potentially dangerous characters are detected, alert the user and let them fix it before trying again. 3) After the exception is generated, deal with it and alert the user. I'm hoping one of the first two options might be able to do somewhat globally...I know for the 3rd I'd have to alter a TON of Try-Catch blocks I already have in place. Doable, but labor intensive. I'd rather be proactive about it if at all possible and avoid the exception all together. Perhaps one approach to #1 would be to write a block of code that could loop through all text entry fields in a formview, during the insert/update event, and strip the characters out. I'm ok with that, but I'd rather not have to heavily alter all my Insert/Update events to accomplish this. Or maybe I just create a different class to do the text checking/deleting, and only insert 1 line of code in each Insert/Update event. If anyone can come up with some example code of any of these approaches that would be a help. Thanks for any ideas or information. I'm definitely open to other solutions too; these are only the 3 that came to mind. I can say that I don't want to turn request validation off though.

  • Prohibit ampersand in Rails form

    - by snlsn
    NOT a Rails 3 issue In a Contact model I have a company_name attribute. For reasons that don't matter to this question, I want to prohibit an ampersand character. We have a lot of clients with ampersands in their company name, and users forget they aren't allowed to use this character. This isn't an html sanitize issue. I don't care about whitespace or CDATA or anything. The entries in this field are plain text and I don't want an ampersand to be entered in this one field in any way, shape or form. I assume a validation on the model is the way to go. I have tried validates_exclusion_of. I have tried validates_format_of. No success. I'm unsophisticated when it comes to regex, so I might be doing things very wrong. But the bottom line is - I need to prevent a user from entering that "&" character in the company_name field. Thanks a million. Steve

  • How to reset ASP.NET MVC client validation mode?

    - by Morten Christiansen
    I'm having a bit of trouble with the client-side validation in the ASP.NET MVC 2 framework and hope someone can help me out. In several situations I find it useful to be able to reset the contents of a form or just a single input element and I need any validation errors to disappear. This in itself is not very hard, and the suggestion provided here works well enough: http://stackoverflow.com/questions/2798427/how-do-i-clear-mvc-client-side-validation-errors-when-a-cancel-button-is-clicked The problem is that, when triggered, client validation goes into an aggressive mode that performs validation on each key press and when an input loses focus. Is there a good way to reset this state as well?

  • JSF - Prevent validationFailed when raising a WARN ValidatorException

    - by Sébastien Tromp
    Hello, I have a form which uses validators for its fields. These validators can send back either Severity.SEVERITY_ERROR or Severity.SEVERITY_WARN messages, as illustrated: if (!isInMainFamily) { FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_WARN, "You should make sure to tag your competency in at least one main category", null); throw new ValidatorException(message); } However, SEVERITY_WARN messages are not blocking for me. They are just a way to tell the user they should correct their input, but won't prevent them from submitting the form and saving their data. However, it seems that throwing any kind of ValidatorException flags the FacesContext as "validationFailed", which then prevents the submission of the form. Is there a way to get around this? Or am I misunderstanding something? Thanks a lot for your help, Sébastien

  • Rails - Why is my custom validation being triggered for only a build command.

    - by adam
    I have a sentence and correction model with a has_one and belongs_to relationship respectively. For some reason when I do def create @sentence = Sentence.find(params[:sentence_id]) @correction = @sentence.build_correction(params[:correction]) a custom validation I wrote for Correction is being called at the build_correction point. the validation is below class Correction < ActiveRecord::Base attr_accessible :text, :sentence_id, :user_id belongs_to :sentence belongs_to :user validate :correction_is_different_than_sentence def correction_is_different_than_sentence errors.add(:text, "can't be the same as the original sentence.") if (text == self.sentence.text) end the problem is for some reason on validation the correction object doesn't have the sentence id set (despite I used the build_correction method) and so it complains "you have nil object .... while executing nil.text" in the if clause in the validation above. So my question is why is the validation occuring for a build command, i thought it only triggers on a create or update. And why isnt the sentence_id getting set?

  • ASP.NET MVC check form input is valid on submit

    - by Gavin
    Hi all, I have a form that when submitted shows a busy animation and disables the submit button. Anyone know how to query Microsoft's Sys.Mvc.FormValidation to see if the form passed it's test so I can prevent the busy animation showing if the form hasn't actually been submitted? Or even some other work-around? At present my client side javascript looks like this: $('form').submit(function() { $('input[type=submit]', this).attr('disabled', 'disabled'); ShowBusy(); }); Cheers, Gavin

Is there any (easy) way to do this? Thanks!

  • Does using the converting input from HTML forms into htmlentities protect attacks invoving JavaScrip

    - by racl101
    Hi everyone, I was wondering if converting POST input from an HTML form into html entities, (via the PHP function htmlentities() or using the FILTER_SANITIZE_SPECIAL_CHARS constant in tandem with the filter_input() PHP function ), will help defend against any attacks where a user attempts to insert any JavaScript code inside the form field or if there's any other PHP based function or tactic I should employ to create a safe HTML form experience? Sorry for the loaded run-on sentence question but that's the best I could word it in a hurry. Any responses would be greatly appreciated and thanks to all in advance. racl101

  • Javascript: Make Rows Draggable Through Input Field Handles

    - by Corey O.
    I have created a table with draggable rows. Unfortunately, most of the rows are covered with a large textbox input element. In order to drag the rows, you have to grab the row on the very edge just outside of the textbox. Is there a way to allow the rows to be grabbed through the textboxes without destroying the textbox functionality? (i.e. relay the mouse drag event, but not the mouseclick event?)
