• HTML form submits and the hostname changes to IP address

  - by Shamik

  I am facing a peculiar problem. The problem is, my webapp is being installed behind a proxy. The request gets submitted to the proxy which forwards the request to the original host that is running the websphere web application. The problem I am facing is, when I access the webapp, its URL looks like the below http://www.myproxy.com Lets say I get a form on this URL, when I submit the form, it is getting submitted to another URL - http://10.1.2.87 Since the URL is changing, application server thinks it is a different session and throws the login page again. The login page comes thru a filter which checks whether user is already authenticated in the session or not. I do not have much knowledge on proxy settings .. where do you think is the problem?

• A beginner's JSF question about form validation

  - by Nitesh Panchal

  Hello, I am having a form and many input elements in that. I want certain fields to be validated, so i keep validateLenth etc on those. And i want some fields to not be validated. For example, i have contact information and address information both on the same page. I want to treat contact information as one group. So if some fields are invalid they should not be submitted and address information to be independent of contact information. Thus, if address information is corrected it should be submitted. I have one form only on the page but two buttons, one for address and one for contact. Simply put :- What is the equivalent of validationGroup of Asp.Net in JSF?

• Creating C# form fields with events based off of a text file

  - by evolve

  I need to generate windows form fields based off of a text file that I am parsing. I also want to automatically generate validation event handlers which all will be basically the same only the form field and the regular expression which is used to validate the field will change. I'm having a difficult time figuring out the quickest and easiest method to go about doing this. Any pointers in the right direction would really be great, maybe even some keywords that I'm missing. I can only imagine this type of question has been covered before, I just don't know what I'm searching for really.

• form tag - is it required on ajax sites?

  - by benpage

  i recently was working on an ASP.NET MVC site that basically serves static html and uses ajax gets to return data to the page when inputs are changed. there is actually no posting or getting from an html input tag on the pages at all. (it is a specific style of site that is not used by the general public, so having compatibility problems for people without javascript is not an issue) after designing the site, i realised that i hadn't even included any form tags. as the site does not use any direct posts or gets, and apart from it being just good html design, i wondered, in my particular situation, if there was any point to having any form tags on the page?

• Java Web App: Passing form parameters across multiple pages

  - by digiarnie

  Hi, what is the best practice or best way of passing form parameters from page to page in a flow? If I have a flow where a user enters data in a form and hits next and repeats this process until they get to an approval page, what ways could I approach this problem to make the retention of data as simple as possible over the flow? I guess you could put all the information as you go in the session but could you get into memory issues if a lot of people are using your app and going through the flow at the same time?

• Conditionally required jsf validation in a4j form

  - by volothamp

  Hello, I'm having a little problem with using conditionally evaluated expression in jsf/a4j Here's my code <a4j:form> <h:inputText id="id1" value="#{mybean.myvalue}" size="1" required="#{not mybean.condition}" rendered="#{not mybean.condition}" requiredMessage="Put a number in here" /> <h:selectBooleanCheckbox value="#{mybean.condition}"> <a4j:support event="onclick" reRender="id1"/> </h:selectBooleanCheckbox> <a4j:commandButton action="#{mybean.myaction}" value="Do something" /> </a4j:form> The boolean checkbox conditionally enable/disable the validation. This doesn't work: the a4j:commandButton simply skip the validation. Thanks.

• php quick form creation

  - by Akshey

  Hi, I have been using php from some time and I have noticed that it takes a long time to create a form with validation using php. Are there any scripts or IDE wizards which can assist a programmer to create php forms quickly and also give the programmer flexibility to customize the form easily? I found some webservices which provide such services but they are mostly oriented towards non-programmers and the forms they generate are not easily customizable and do not support all kinds of functionalities. Infact, most of them are meant for generating contact forms. Regards, Akshey

• MVC binding form data problem.

  - by John

  I am using an object that matches all the fields in my form. I then use the default binding to populate the object in my action, like this; public ActionResult GetDivisionData(DivisionObj FormData) My DivisionObj initializes all it's values to string.empty in the constructor. The problem is that when the binder populates the model from the posted form data, any data that is not posted is set to null in the object, eventhough I initialized the object to contain empty strings. Is there a way to change this so that unposted data will be an empty string.

• Javascript form validation events

  - by user307922

  Hi All, I am making a small form for a php app and had a question regarding javascript validation. What is the best event to run the javascript validation on the input value? Is it the "focusout" event? I used "focusout" to originally but it creates problems when the user hits enter while they are still focused on any particular field in the form. Should I run the js validation when the user clicks submit? Just looking for some advice. Thanks! Chuck

• Developing a very nonstandard Drupal form

  - by monksp

  I'm creating a site for a local retail shop using Drupal. Everything's been going very smoothly up until this current bit. It's a comic shop, and I want to make a place where people can manage their own subscriptions. Since the number of different titles a customer subscribes to can vary pretty widely, I want a way to make a completely dynamic form, with people able to add as many new lines as they need and I'm really struggling with Drupal's documentation. Essentially, I'd like the final version of the page to look something like this: http://www.monksp.org/foo.html Anyone have any experience building a drupal form like this?

• Passing javascript form variables into jQuery function not working

  - by Chase

  I am trying to pass some JavaScript variables that I have assigned to form variables into a query string used by a jQuery plug in called fancybox.

• InfoPath browser form submitting dirty fields changed through javascript

  - by Xavier

  I'm trying to submit an InfoPath browser form with fields that have been modified through the Spell Checker included in Sharepoint server. The spell checker checks all the fields in the page and once the user closes the SpellChecker dialog, it changes the textboxes with the new values through javascript. When I click Submit, debug the FormEvents_Submit in the form code behind and try to do a GetNodeValue("XPath to changed field"), it still shows the old values. I realize that this may be a problem of doing postbacks and I'd like to do a full page postback once the SpellChecker is done changing all the textboxes. Any suggestions would be appreciated. Thanks.

• Gridview with row being edited causing error when form submitted

  - by Chris Phelps

  Using ASP.NET VB, I have a form with some text boxes and a Gridview. If a user clicks the Edit button on a row in the gridview, and then tries to submit the form with a row still in edit mode on the Gridview, this error is generated - "Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. " Any idea how to prevent this error??

• simple form validation in dancer/perl

  - by devnull

  I am trying to do a simple form validation in perl dancer but I was wondering what would be the best way to validate simple parameters (e.g. field cannot be empty, validity of the email, minimum length of a field) in dancer/perl without any extra plugin or CPAN module here is the code so far post '/register' => sub { my $db = connect_db(); my $sql = 'insert into users (username, email, password, motivation) values (?, ?, ? ,?)'; my $sth = $db->prepare($sql) or die $db->errstr; $sth->execute(params->{'username'}, params->{'email'},params->{'password'}, params->{'motivation'}) or die $sth->errstr; set_flash('Hey you signed up !'); redirect '/thanks'; }; I did google it and I found several ways to do validation using CPAN modules like Form::Foo but how do it without that ?

• Sync offline JQuery Mobile form

  - by Dimas

  My name is Dimas and I work as a developer in a hospital. I've developed a web form with JQuery Mobile which is accessed from an Android tablet. It sends data (text and FILES) to the server (PHP) and it's saved in a MySQL database. This tablets are used by doctors that are visiting the patients in their homes. Some of these patients live in remote areas with very bad Internet connection, so I'm thinking on use HTML5 Offline feature to solve these situations. I started reading about it but I'm newbie with this technology. I've some questions: Do you think this is the best/easiest solution? If I could save the form data in a local sqlite storage when the tablet is offline, how I could synchronize it with the data in MySQL server when the tablet become online? Thanks

• Writing custom Django form fields and widgets

  - by hekevintran

  Django has very good documentation that describes how to write custom database fields and custom template tags and filters. I cannot find the document that describes how to write custom form fields and widgets. Does this document exist? The way I've been able to write custom form fields and widgets is by reading the Django source code and imitating what I see there. I know that there are still things about implementing fields and widgets that I do not completely understand because I have not read any high level document that describes their interfaces.

  I have a few images that i need to upload using an online form.
