JQuery :: How To Validate PHP Generated Forms
Apr 25, 2011
I am rather new to JQuery and would like to use it with php. I ran into problems when my html is not static, I generate php forms on the fly using my php script and JQuery just doesn't seem to validate those forms. When put the same form in static html file JQuery works like a charm. What could be wrong? Does JQuery need a page to be static? Right after I load my php page firebug reports that $(document).ready(function() { is not a function and JQuery is not defined. I have loaded the necessary JQuery libraries.

I am using the JQuery validation plug in for form validations. My page contains a loop in which dynamic forms are generated and within each form some text fields are also dynamically generated. I have assigned the id and name attributes both to form and fields with dynamically appending a value. Now I want to apply the validation on all these form, please note that each form contains its own submit button. I have tried using the following selector,

I have a database that shows about 5 to 10 recorrds on a page that contain forms for the user to fill out. The number of rows is unknown and depends on the user query.On the page there can be 2 or 10 records displayed ..each containing a form that needs to be validated.How can i use that. The IDs of the elements would have to be generated dynamicly i suppose. Anyone of you got an idea how to do that ?

When I add a tab, whose content is a form. The form is loaded by ajax $.ajax('url'); On ajax complete, I add a custom method for validation, which is supposed to get called when the "Upload" button in the form is clicked, but it never get called. I have searched and tried multiple things for two days now, and nothing works.

I've a page that has 2 forms. If the user clicks the bottom form the validations appear and everything goes red but the Top form is a required field but it doesn't as it's a separate form. How can I validation form0 and form1 together to show to the user the required fields. When the user clicks form0 it goes over to a pagedLIst, the user returns and textfield gets populated with the product that as selected. So when they hit form1, that value gets passed through as a hiddenfield..
<form id="form0">
...text box input to search for your product, returns to this page populated the found product
<input class="button" id="FindProduct" type="submit" value="Find Product" name="action"/>

I am using a variation of the multipage form in the demo and run into a small problem with the pageRquired function. Seems it does not validate correctly if you add any custom selectors after the pageRequired. I am trying to make one field required depending on whether another field is blank. E.g.:
class="{pageRequired: '#field1:blank'}"
In this case, the validation is completely ignored, even if I have {pageRequired:true}. It will only validate if I have class="pageRequired" without the curly brackets. However, if I set it up in rules, it will make the field2 required regardless of the value of field1, e.g.: $(document).ready(function(){
$("#myform").validate({
rules: {
field2: {
pageRequired: "#field1:blank"
}}, debug:true
});
On a whole the multipage validation works very well but not with any custom selectors such as :blank, :filled etc or by using curly brackets in the class. Is there a way around this? I would really prefer to use inline validation using class statements and still be able to use custom selectors. View this message in context: [URL].

I m aware of various ways to validate forms using JQuery, but here I have a complex thing, and i need the most optimized code for it... Basically I have a form made up of rows each containing a number of input text fields which are repeated on a the following rows however of course with different IDs and names... There is no need to fill all the rows, but it is necessary to fill all the fields of a specific row. Now I was wondering, how can i make sure that each row is properly filled? knowing that some rows will be totally blank [which is okay]

I've used the excellent validate plugin (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) to add JS validation to forms. I'm aware there's a built-in setting to validate an email address. However, I'd like to validate a list of email addresses, and I don't think the plugin contains a built-in solution. What's the best way to implement this?

I see it working in the demos I found this documentation
You can avoid having to duplicate the plugin settings by modifying the defaults. Use $.validator.setDefaults({…}) to override multiple settings at once.
But I do not understand what I have to do to make this work

I know that this must be quite trivial to most of you, but my skills
in JavaScript are weak.
I am looking for a way to validate all forms throughout a website
through one validation script.
How do I determine the form's name (or id) value to implement
conditional validation?
i.e. if (form1) { validate like this }; if (form2) { validate like
this };

I am a newbie trying to generate an alert message when a user leaves a username filed blank in an html form using an external javascript. Following is the code for html file.
[Code]....
However, if I swap the positions of the username and first name i.e. place the first name before the username, I do get an alert message if the first name is left empty. I do not wish to hijack an existing thread. Please let me know if there is an existing thread on this issue..(I could not find one).

I need it to check that the name, email and message field have been filled out (which currently works fine) but also to check that the email is a valid address. This is my attempt at doing this, it works with the fields not being filled out, but does check that the email is valid?

I'm would like to add a light box to a site that has content generated by php. Basically it is a property site and will have a thumbnail image and description. When the user clicks on thumbnail I would like to display a gallery of pictures relevant to the property. Each property will be generated dynamically by php. My question is how do I enter the selector for the gallery into jquery. I am thinking of using Fancy Zoom as you can use hidden elements, as the gallery will be hidden.

how to add forms in javascript, but it's limited to text input forms.
<script type="text/javascript"><!--
function updatesum() {
document.form.sum.value = (document.form.sum1.value -0) + (document.form.sum2.value -0);
}
//--></script>
Where the inputs sum1 and sum2 are text fields you put whatever numbers you want in. That works fine. Great. Now what I'm having trouble with is modifying the code so that it will add one form with an input number with a form that spits out a randomly generated number.
<input type="button" value="D20" onclick="this.form.display.value = Math.round (20 * Math.random())" class="buttonHi" /> <input name="display" type="text" size="6" value="" />
This is what I'm using for my random number generator. So basically I want to be able to put, say, 5, into the input text field above this. And then click on the d20 button to get a random number, say, 15, and then have the first code add the inputted 5 with the randomly generated 15.

I'm using the validation plugin [url]
I must be missing something, is there not an easy way to validate inline?
For example, I have a required text input that is given focus on page load, I would like for it to throw an error if the user moves to the next field w/o entering any data.
Right now, it only checks for errors on 'submit'.

I have a form (form1) to register with the fields: user, email, password being validated normally.
Have a second form (Form2) to the user update the data registered in form1, and the fields user, email, password is already populated with data from the database, the email field I use the remote validation, and as the field already has been completed and read always says that this email already exists, how do I create a rule or method so that when the field is already filled it not do so validating and validate if it is filled with a new email. Email2 have a hidden field in order to do a test type.

I'm working under certain constraints wherein,at a certain point outside my direct control,validate is called with no arguments, but after that I want to set a custom validation function on a form field. I figure there's got to be a way to manipulate validate's internal data structure to add the function, but I don't have a clue as to how.

I have a section of a form containing elements that are not visible, currently just in a hidden div. Some of these elements have validation on them so when the form is submitted it fails on this validation.What I am after is a way to stop the validation firing for any hidden elements. I have tried setting them to 'display: none' and 'visibility: hidden' but this does not have any affect.

I have an MVC application and I am trying to do some validation but the Validate doesn't seem to fire. I can get it working in a basic html page but for some reason it is not working in my aspx page and I am not sure why. I have all the js files included that I need and the CSS classes defined exactly as they are in the basic example in the jQuery documentation. Here is my code:

I'm new to the forums, yet not new to jQuery. Still, I never had to get properties from objects generated on-the-fly, till now. I have a pager generated by cycle plugin, for each slide, a button is created, and the container of those buttons is enlarged. The amount of slides is determined by the user, so can't specify a default or maximum width. When I examine the object with firebug, I get the full width, including the generated pager buttons. But my script keeps on getting 0 as width, which is the width of the element when the page loads.
Anyway, is there a way around this? In case I haven't explained myself well, say it and maybe I can paste the code.
