Today, in our PHP tutorial, we’ll be shown the implementation process for submitting AJAX forms in PHP with Jquery Ajax Post Example or you can say Jquery submit form Ajax. In this Ajax example demo, we’ll use serialize method for creating URL encoded text string by serializing form values.

I'm trying to send a lot of data from a form using the $.post method in jQuery. I've used the serialize() function first to make all the form data into one long string which I will then explode serverside.The weird thing is when I try and send it using $.post it appends the result of the serialize() to the URL as if I was sending it using GET. Anyone have any ideas why this is happening?
Here's the jquery:
here's the php:

The.serializeArray method creates a JavaScript array of objects, ready to be encoded as a JSON string. It operates on a jQuery collection of forms and/or form controls. The controls can be of several types. The weird thing is that the same code tested on my local machine works fine. If I upload the files on my hosting space it stops working. I tried doing an old-fashioned form without using jQuery and all data was correct. I don't see how this would be a server configuration problem. The serialize method creates a URL encoded text string by serializing form values. You can select one or more form elements (like input and/or text area), or the form element itself. The serialized values can be used in the URL query string when making an AJAX request. JQuery has a method “serialize” to serialize form data. However, J avaScript serialize form do not support this method directly. To allow form data serialize in JavaScript, we must import a library from google. Submit HTML Form data using regular jQuery ajax function. It is very flexible and can be configured to the heart content.

If you are using a
<button>
element to activate the serialize and ajax, and if that <button>
element is within the form
element, the button
automatically acts as a form submission, no matter what other .click assignment you give it with jQuery.
type='submit'
<button></button>
and <button type='submit'></button>
are the same thing. They will submit a form if placed within the <form>
element.
type='button'
<button type='button'></button>
is different. It is just a normal button and will not submit the form (unless you purposely make it submit the form via JavaScript).
And in the case where a form element has no action attribute specified, this submission simply sends the data back onto the same page. So you will end up seeing a page refresh, along with the serialized data appearing in the URL as if you used GET in your ajax.
Possible solutions
Jquery Serialize Form Post Example
1 - Make the
<button>
type button
. As explained above, this will prevent the button from submitting the form.

After:
2 - Move the
<button>
element outside the <form>
element. This will prevent the button from submitting the form.
Before:
After:
3 - Add in the
preventDefault()
into the button click handler to prevent the form from being submitted (it's default action):
Obviously without seeing all your code, I have no idea if this is the case for your issue, but the only reason I have ever seen behavior you are describing is because the submit button was a

try using serializeArray() instead of serialize(). serialize() will produce an url-encoded query string, whereas serializeArray() produces a JSON data structure.

What leads you to believe that the data is appended to the URL?
Anyway, wouldn't it make more sense to pass the form values in the form data itself? It will allow you to skip the 'explode' step:
This is OK.STEP 3: Using your virtual machine software, assign your Cricut (which will appear as an FTDI USB to Serial adapter in your VM software) to the VM. Nothing will appear on the screen. Sure cuts a lot 4 download free. Your XP virtual machine should behave as if you have just plugged in your Cricut.STEP 4: Open up Cricut Design Studio.

So this is probably a bit obtuse, but I made a function to help me do this very thing since I got tired of making a bunch of fixes every time. serializeArray is kind of annoying because it provides a collection of objects, when all I wanted to have PhP reconstruct was an associative array. The function below will go through the serialized array and will build a new object with the appropriate properties only when a value exists.
Firstly, the function (it takes the ID of the form in question):
When constructing my posts I also usually use an object since I usually tag on two or three other values before the form data and I think it looks cleaner than to define it inline, so the final step looks like this:
Server-side all you have to do is
$payload = json_decode($_POST['data'], true)
and you have yourself an associative array where the keys are the names of your form fields.
Full disclaimer though, multiple-selects probably won't work here, you would probably only get whichever value was last on the list. This is also created very specifically to suit one of my projects, so you may want to tweak it to suit you. For instance, I use json for all of my replies from the server.

Try this syntax. I use this to serialize a form and POST via ajax call to WCF service. Also, you can send this back a single JSON object instead of building the object the way you are. Try this:

On the php side, you may want to look into parse_str. It will parse that url string into variables, or into an array if you utilize the 2nd optional parameter.

One more possible reason for this issue: If you have a form without any sort of submission action assigned to it, whenever you press the 'ENTER' key while filling out the form, the form will be submitted to the current URL, so you will see the serialized data appear in the URL as if you were using a GET ajax transaction. A simple solution to this problem, just prevent ENTER from submitting the form when its pressed:

Your server is receiving a string that looks something like this (which it should if you're using jQuery serialize()):
..something like this is probably all you need:
$params
should then be an array that contains all the form element as indexes

If you are using
.serialize
, you can get rid of this:
You data will be available as follows with
.serialize
:
Jquery Send Form Post Serialize
It should be:
On PHP side you simple need to access it using the
$_GET['sort']
.
Edit:
To view the data, you should define a div with id
result
so that the result returned is displayed within this div.
Example:
Hyder B.Hyder B.
