AJAX call failing to process form

I have an email sign-up form on a website.
The form appears in two areas of each web page: the header and the footer
It's the same exact form, just available on the top and bottom of the page for better UX and accessibility.
The form uses a jQuery/AJAX script to provide success and error responses to the user. (i.e., "Success! Your subscription is complete." and "Error. Please review and re-submit")
The problem I'm having is that the header form processes but the footer form does not.
Any ideas what's wrong with this code? Thanks.
P.S. The form was working perfectly when the header and footer forms each had their own script. The problem started when the scripts were consolidated into one file. I've posted the original scripts at the bottom. Also, nothing has been changed in the PHP, so I don't think the problem is there.
$(function() {
// get the forms
var form = $('#header-form, #footer-form');
// set up event listener
$(form).submit(function(e) {
// disable html submit button
e.preventDefault();
// get the submit button
var submitButton = $('[type=submit]', this);
// get the messages element
var formResponses = $('#header-form-responses, #footer-form-responses', this);
formResponses.text(" ");
// serialize form data
var formData = $(form).serialize();
// disable submit button to prevent unnecessary submission
submitButton.attr('disabled', 'disabled');
// tell users that form is sending
submitButton.text('Processing...');
// submit form via AJAX
$.ajax({
type: 'POST',
url: $(form).attr('action'),
data: formData
})
.done(function(response) {
// make sure formResponses element has 'success' class
$(formResponses).removeClass('error');
$(formResponses).addClass('success');
// set message text
$(formResponses).text('Your subscription is complete. Thank you!');
// clear form
$('input').val('');
})
.fail(function(data) {
// make sure formResponses element has 'error' class
$(formResponses).removeClass('success');
$(formResponses).addClass('error');
// set the message text
$(formResponses).text('Input error. Please review and re-submit.');
})
.always(function(data) { // this will always fire even if the request fails
submitButton.removeAttr('disabled');
submitButton.text('Send');
});
});
});

<!-- simplified HTML -->
<form action="form_processing.php" method="post" id="header-form">
<input type="email" name="email_subscription">
<button type="submit" id="header-form-submit">Submit</button>
<div id="header-form-responses"></div>
</form>
<form action="form_processing.php" method="post" id="footer-form">
<input type="email" name="email_subscription">
<button type="submit" id="footer-form-submit">Submit</button>
<div id="footer-form-responses"></div>
</form>
Here's the original header code (works perfectly):
$(function() {
var form = $('#header-form');
var formResponses = $('#header-form-responses');
var submitButton = $("#header-form-submit");
$(form).submit(function(e) {
e.preventDefault();
var formData = $(form).serialize();
submitButton.attr('disabled', 'disabled');
submitButton.text('Processing...');
$.ajax({
type: 'POST',
url: $(form).attr('action'),
data: formData
})
.done(function(response) {
$(formResponses).removeClass('error');
$(formResponses).addClass('success');
$(formResponses).text('Your subscription is complete. Thank you!');
$('input').val('');
})
.fail(function(data) {
$(formResponses).removeClass('success');
$(formResponses).addClass('error');
$(formResponses).text('Input error. Please review and re-submit.');
}).always(function(data) {
submitButton.removeAttr('disabled');
submitButton.text('Send');
});
});
});
Here's the original footer code (works perfectly):
$(function() {
var form = $('#footer-form');
var formResponses = $('#footer-form-responses');
var submitButton = $("#footer-form-submit");
$(form).submit(function(e) {
e.preventDefault();
var formData = $(form).serialize();
submitButton.attr('disabled', 'disabled');
submitButton.text('Processing...');
$.ajax({
type: 'POST',
url: $(form).attr('action'),
data: formData
})
.done(function(response) {
$(formResponses).removeClass('error');
$(formResponses).addClass('success');
$(formResponses).text('Subscription complete.');
$('input').val('');
})
.fail(function(data) {
$(formResponses).removeClass('success');
$(formResponses).addClass('error');
$(formResponses).text('Input error. Please review and re-submit.');
}).always(function(data) {
submitButton.removeAttr('disabled');
submitButton.text('Send');
});
});
});

Within the $(form).submit( you're still using $(form), eg
var formData = $(form).serialize();
as form = $('#header-form, #footer-form') any call to $(form) (or just form) will affect/apply to/read from both forms. This depends on what the call is, eg form.attr("action") will always get the action from the first form.
Within the handler, change all $(form) (or just form) to $(this):
var formData = $(this).serialize();
...
url: $(this).attr('action'),
be careful using this inside a callback, so if you do need the relevant form then instead, change to
$('#header-form, #footer-form').submit(function(e) {
var form = $(this);
and continue to use form.
Note that in your code form is already a jquery object, but jquery allows you to "double wrap" - ie $(form) is the same as $($(form))
I recommend you remove the outer form variable completely, ie change to
// set up event listener
$('#header-form, #footer-form').submit(function(e) {
which will help to remove the issue of using form not meaning this form.

JavaScript return false is not working

I'am trying to use google invisible reCAPTCHA with AJAX. But returne false is not working.
JS:
function onSubmit(token) {
var siteurl= 'http://localhost/test/';
document.getElementById("register").submit();
var formdata = $('.register').serialize();
$.ajax({
method: "POST",
url: siteurl+"app/ajax/test.php",
data: formdata
})
.done(function( msg ) {
alert(msg);
});
return false
}
HTML:
<form id="register" action="" method="post" class="register">
<input class="for-1" type="text" name="field" >
<input class="g-recaptcha" data-sitekey="6LfCqCAUAAAAAAjaAg5w_mHK" data-callback='onSubmit' type="submit" value="Submit">
</form>
this codes working well but not returning false.
iam waiting help,
thanks.

Well if you wan't to avoid your page from reloading when form is submitted
I suggest you use this flow
1 -> data-callback='onSubmit' attribute is no longer need
2 -> remove function onSubmit and replace it with event listener
this code will listen if your form register is being submitted
$(document)
.off('submit', '.register')
.on('submit', '.register', function(e) {
/** Do what you want when submitting the form **/
var siteurl= 'http://localhost/test/';
var formdata = $('.register').serialize();
$.ajax({
method: "POST",
url: siteurl+"app/ajax/test.php",
data: formdata
})
.done(function( msg ) {
alert(msg);
});
/** prevent form from submitting to your form action page **/
e.preventDefault();
});
3 -> also document.getElementById("register").submit(); remove this since your form is already been submitting
e.preventDefault(); what this line do is it will prevent form from submitting to your form action page

How do I use AJAX to print out data inside a div?

I have two files. One file is named index.php and another file is named process.php.
I have a form that submits to process.php in index.php:
<form class="form" action="process.php" method="POST" name="checkaddress" id="checkaddress">
<table>
<tr class="element">
<td><label>Address</label></td>
<td class="input"><input type="text" name="address" /></td>
</tr>
</table>
<input type="submit" id="submit" value="Submit"/>
</form>
<div class="done"></div>
I also have a process in process.php to echo some data based off of the input. How would I be able to use AJAX to submit the form without leaving the page?
Is it something like:
$.ajax({
url: "process.php",
type: "GET",
data: data,
cache: false,
success: function (html) {
$('.done').fadeIn('slow');
}
});
What page would I put the above code on if it was right?
Also, how do I change the above code to say what the process.php outputted? For example, if I echo "Hello" on process.php, how do I make it say it in the done div?
I have seen many responses regarding AJAX, but they all rely on data that is pre-made like APIs. I need to do a database query and fetch the data dependent on the address entered and print the data out.

You need to collect the data in the form so that you can submit them to the process page, and you need to run your code when submitting the form (and cancel the default form submission)
$('#checkaddress').on('submit', function(e){
// get formdata in a variable that is passed to the ajax request
var dataToPassToAjax = $(this).serialize();
$.ajax({
url: "process.php",
type: "GET",
data: dataToPassToAjax,
cache: false,
success: function (resultHtml) {
// add the returned data to the .done element
$('.done').html( resultHtml ).fadeIn('slow');
}
});
// cancel the default form submit
return false;
});
[update]
If you want to modify the data before submitting them, you will have to manually create the parameters to pass to the ajax
$('#checkaddress').on('submit', function(e){
// get formdata in a variable that is passed to the ajax request
var dataToPassToAjax = {};
var address = $('input[name="address"]', this).val();
// alter address here
address = 'something else';
dataToPassToAjax.address = address;
$.ajax({
url: "process.php",
type: "GET",
data: dataToPassToAjax,
cache: false,
success: function (resultHtml ) {
// add the returned data to the .done element
$('.done').html(resultHtml ).fadeIn('slow');
}
});
// cancel the default form submit
return false;
});

You could use the jQuery form plugin: http://jquery.malsup.com/form/

CakePHP jQuery async upload

I am trying to create an async file upload but I am hitting a wall. Here is what I have, in an element:
Element:
<div style="border:0px solid darkgray; width:100%; text-align: right; text-decoration: underline; font-weight: bold;">
<form id="upload_form" enctype="multipart/form-data">
<input type="file" accept="" id = "templatePath" name = "templatePath" name="MAX_FILE_SIZE" value="104857600">
<input type="submit" value="Submit" id = "bntSubmit" name = "bntSubmit" onclick="submitFileUpload();" >
</form>
</div>
JQuery:
function submitFileUpload(){
try{
var FileUrl = "/staff/passport/upload_file/";
var request_timeout = 50000;
var formData = new FormData();
var files =$( '#templatePath' )[0].files[0];
formData.append( 'templatePath', files);
$.ajax({
url: FileUrl,
type: 'POST',
timeout: request_timeout,
cache: false,
contentType: false,
processData: false,
data:formData,
beforeSend: function(xhr ){
},
success: function(data) {
try{
if(data.status =='ok'){
}else{
}
}catch(ex){
}
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
}
});
return false;
}catch(ex){
}
}
Controller function:
public function upload_file(){
try{
$this->autoRender = false;
} catch (Exception $e){
return $this->EncodeError($e);
}
}
The jquery seems to be fine. Break points are hit and I can see that the object "files" is created and has the file attributes. The controller function also gets called but the form data does not show up in my debugger (nothing in "this" or _FILES[] or any other variable). Can anyone help out?
thanks

Based on your comment, you are nesting the File upload element within another form. From nesting is not valid HTML and will confuse browsers besides not giving you the expected result. Refer to this answer.
The only solution is to remove the file upload form from within your original outer form and place it outside. Use CSS to make the upload form appear within your original form.

using jquery to make ajax call and update element on form submit

Here is my html form
<div id=create>
<form action=index.php method=get id=createform>
<input type=text name=urlbox class=urlbox>
<input type=submit id=createurl class=button value=go>
</form>
</div>
<div id=box>
<input type=text id=generated value="your url will appear here">
</div>
Here is the javascript im trying to use to accomplish this;
$(function () {
$("#createurl").click(function () {
var urlbox = $(".urlbox").val();
var dataString = 'url=' + urlbox;
if (urlbox == '') {
alert('Must Enter a URL');
}else{
$("#generated").html('one moment...');
$.ajax({
type: "GET",
url: "api-create.php",
data: dataString,
cache: false,
success: function (html) {
$("#generated").prepend(html);
}
});
}return false;
});
});
when i click the submit button, nothing happens, no errors, and the return data from api-create.php isnt shown.
the idea is that the new data from that php file will replace the value of the textbox in the #box div.
i am using google's jquery, and the php file works when manually doing the get request, so ive narrowed it down to this

Because you're binding to the submit click instead of the form's submit.. try this instead:
$('#createForm').submit(function() {
// your function stuff...
return false; // don't submit the form
});

Dan's answer should fix it.
However, if #createurl is not a submit/input button, and is a link styled with css etc., you can do this:
$('#createurl').click(function () {
$('#createForm').submit();
});
$('#createForm').submit(function () {
// all your function calls upon submit
});

There is great jQuery plugin called jQuery Form Plugin. All you have to do is just:
$('#createform').ajaxForm(
target: '#generated'
});
