How to store an incomplete multi-step form? - javascript

I currently have a form that is multi-step; it doesn't do anything fancy per step, it simply does display: none on the previous step to hide the previous fields and move the user forward.
It submits via AJAX and has required fields.
Is there any way to capture the data from each step of the form, and then, if the user drops off or never submits the form, send the captured data - I'm not worried about any issues in regards to data protection, as it doesn't apply in this situation.
The form basically looks like this:
<form>
<div class="step-1">
<label>First Field
<input type="text" id="field1" name="field1" maxlength="50">
</label>
<label>Second Field
<input type="text" id="field2" name="field2" maxlength="50">
</label>
next step
</div>
<div class="step-2">
<label>Third Field
<input type="text" id="field3" name="field3" maxlength="50">
</label>
<label>Fourth Field
<input type="text" id="field4" name="field4" maxlength="50">
</label>
<input type="submit" id="send" name="submit" />
<span id="submitdata"></span>
</div>
</form>
The bit I'm struggling with is knowing when the user drops... Does it need to invoke some kind of session per the form?


You could automatically submit the form when the user leaves the page, using the beforeUnload event:
var notSubmitted = true;
$('form').on('submit', function() { notSubmitted = false; });
$(window).on("beforeunload", function() {
return notSubmitted ? $('form').submit() : null;
})
$("form").submit(function (e) {
e.preventDefault();
// ... ajax submission goes here ...
return false;
});
If you need to record that it is a 'by default' submission, then you could use a hidden form element instead of the variable notSubmitted. The hidden element would give you that data in the form.


Try this code:
$(document).ready(function () {
//alert("hi");
setTimeout(function () {
$("#msg").hide(1000);
}, 3000);
$("form#product_form").submit(function (e) {
//alert('hi');
e.preventDefault();
var formData = new FormData($(this)[0]);
$.ajax({
url: '<?php echo site_url('C_home/pro_add'); ?>',
type: "POST",
data: formData,
dataType: "json",
contentType: false,
processData: false,
success: function (result) {
//alert(result);
$("#product_form").trigger('reset');
window.location.href = "<?php echo site_url('C_home/data_tbl'); ?>";
}
});
return false;
});
$("#product_form").validate({
rules: {
name: "required",
category_id: "required",
image: "required",
description: "required",
qty: "required",
price: "required"
},
messages: {
name: "Product name is required",
category_id: "Please Select Category name",
image: "Plases Select Product Image",
description: "Product Description is required",
qty: "Product Quantity is required",
price: "Product Price is required",
}
})
});

The condition if (isset($_POST['submit'])) { will never evaluate to true, since there is no input element in the form with name="submit" (the button with name='submit' does not send the attribute by default).
Either change the condition:
if (isset($_POST['quest_t'])) { ...
Or, include an input element with name='submit', for example:
<input name="submit" type="hidden" />
Also, make sure to move the $_POST check at the beginning of the file and ensure that no other code will be evaluated in the PHP file (e.g. the rest of the HTML code) if a POST request has been received.

Just return false after at the end of the method.
jQuery has its own way of ensuring "preventDefault()" and it is just returning false from the submit handler.
Full background on this here:
event.preventDefault() vs. return false

Issue has been solved. By changing path and then putting path of js file again.

Text not carrying over to POST variable

Here is the HTML: Line 18 below is not carrying over to $_POST['storename'] after Submit is hit. All other text fields are carrying over just fine. The only difference is that this autofills with data from database using PHP and AJAX. I've attached all coding in reference to that field.
Here's the link to the site: http://drmwebdesign.com/project002/product-insert.php
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<div class="row uniform 50%">
<div class="6u 12u(mobilep)">
<input type="text" name="pname" id="pname" value="<?php echo $pname;?>" placeholder="Product Name" />
</div>
<div class="6u 12u(mobilep)">
<input type="text" name="brand" id="brand" value="<?php echo $brand;?>" placeholder="Product Brand" />
</div>
<div class="6u 12u(mobilep)">
<input type="text" name="price" id="price" value="<?php echo $price;?>" placeholder="Product Price" />
</div>
<div class="6u 12u(mobilep)">
<input type="text" name="upc" id="upc" value="<?php echo $upc;?>" placeholder="Product UPC" />
</div>
</div>
<div class="row uniform">
<div class="12u">
<input type="text" name="storename" id="storename" class="form-control" placeholder="Enter Store Name" />
<div id="storeList"></div>
</div>
<div class="12u">
<ul class="actions align-center">
<li><input type="submit" value="Submit Product" /></li>
</ul>
</div>
</div>
</form>
<script>
$(document).ready(function(){
$('#storename').keyup(function(){
var query = $(this).val();
if(query != '')
{
$.ajax({
url:"php/storelist.php",
method:"POST",
data:{query:query},
success:function(data)
{
$('#storeList').fadeIn();
$('#storeList').html(data);
}
});
}
});
$(document).on('click', 'li', function(){
$('#storename').val($(this).text());
$('#storeList').fadeOut();
});
});
</script>

Try the following :
1) Use the chrome network to check the request / response
2) If the field contains a long data check the max post size
3) If the field is a list, and you are selecting multiple choices you need to check this question
4) check if multiple fields have the same name/id

$(document).on('click', 'li', function(){
$('#storename').val($(this).text());
$('#storeList').fadeOut();
});
Triggers when you press the submit button, setting #storename value to nothing.
Add a class to the store names and target onclick using that.

Not getting any value in $_POST after from submit

And here is my javascript from which I am call the page
var options = {
beforeSubmit: showRequest,
success: showResponse,
url: site_url + 'controllers/ajax_controller/modules-ajax-controller.php',
type: "POST"
};
$('#form_modulesadd').submit(function() {
$(this).ajaxSubmit(options);
return false;
});
after submitting the page I am not getting any values in $_POST
this code is working fine in the server.
In local Environment it's giving problem
I am using wamp server. I have already tried with var_dump(),print_r() but not getting any result.
Any help would be appreciated.
Thanks in advance.

In your options, you should specify the data that you want to send.
var options = {
beforeSubmit: showRequest,
success: showResponse,
url: site_url + 'controllers/ajax_controller/modules-ajax-controller.php',
type: "POST",
data: {data1: "your_data", data2: "your_data"}
};
Then, try:
<?php echo $_POST["data1"]; ?>
It will show the data send, here: your_data

Use data option to send the data to the server.
var options = {
...
data: $('#form_modulesadd').serialize(),
...
};
$('#form_modulesadd').serialize() will send the data from the form.
EDIT
Try ajax:
$('#form_modulesadd').submit(function() {
$.ajax(options);
return false;
});

use <form name="form_modulesadd" id="form_modulesadd" method="POST" enctype="multipart/form-data" action="<?=site_url?>controllers/ajax_controller/modules-ajax-controller.php'" class="form-horizontal" >

how to use jquery/ajax validation in cakephp?

i have embedded jquery and and it is working ..but there is a small problem with that query... when empty form is submitted , it shows errors with fieds and the form without error...i mean.. it shows double input field... what should be the main problem behind this...?
here is contoller Action:
public function add() {
if ($this->request->is('post')) {
if(!empty($this->data)){
$this->Post->create();
if ($this->Post->save($this->data)) {
if($this->RequestHandler->isAjax()){
$this->render('success','ajax');
}
else{
$this->Session->setFlash(__('Your post has been saved.'));
$this->redirect(array('action' => 'index'));
}
}
$this->Session->setFlash(__('Unable to add your post.'));
}
}
}
public function validate_form()
{
if($this->RequestHabdler->isAjax())
{
$this->data['Post'][$this->params['form']['field']]=$this->params['form']['value'];
$this->Post->set($this->data);
if($this->Post->validates()){
$this->autoRender=false;
}
else {
$error=$this->validateErrors($this->Post);
$this->set('error',$error[$this->params['form']['field']]);
}
}
}
here is validation js file:
$(document).ready(function (){
$('#title').blur(function(){
$.post(
'/cakephp/posts/validate_form',
{field:$('#title').attr('id'),value:$('#title').val()},
handleTitleValidation
);
function handleTitleValidation(error)
{
if(error.length>0){
if($('#title-notEmpty').length==0){
$('#sending').after('<div id="notEmpty" class="error-message">'+error+"</div>");
}
}
$('#title-notEmpty').remove();
}
});
$('#body').blur(function(){
$.post(
'/cakephp/posts/validate_form',
{field:$('#body').attr('id'),value:$('#body').val()},
handleBodyValidation
);
function handleBodyValidation(error)
{
if(error.length>0){
if($('#body-notEmpty').length==0){
$('#sending').after('<div id="notEmpty" class="error-message">'+error+"</div>");
}
}
$('#body-notEmpty').remove();
}
});
});
here is add.ctp
<!-- File: /app/View/Posts/add.ctp -->
<?php echo $this->Html->script('jquery',false);?>
<?php echo $this->Html->script('validation',false);?>
<div id="success" style="background-color: lightgreen;"></div>
<h1>Add Post</h1>
<?php
echo $this->Form->create('Post');
echo $this->Form->input('title', array('id'=>'title'));
echo $this->Form->input('body', array('rows' => '3','id'=>'body'));
echo $this->Js->submit('Save Post', array(
'before'=>$this->Js->get('#sending')->effect('fadeIn'),
'success'=>$this->Js->get('#sending')->effect('fadeOut'),
'update'=>'#success'
) );
?>
<div id="sending" style="display:none;">
<?php echo $this->Html->image('ajax-loader.gif', array('alt' => 'Loading...')); ?>
</div>
this is what i get... html source code:
<form id="PostAddForm" accept-charset="utf-8" method="post" action="/cb/cakephp/posts/add">
<div style="display:none;">
<input type="hidden" value="POST" name="_method">
