Feb 17, 2017 I want to submit this form via jquery ajax, this is what I have made and it is not working. Form is submitting with page refresh and I am not seeing the response i.e. Printing array on the sam. Save Your Code. If you click the save button, your code will be saved, and you get an URL you can share with others. In this case, jQuery serializes the successful controls within the form. Only form elements are examined for inputs they contain, in all other cases the input elements to be serialized should be part of the set passed to the.serialize method. Selecting both the form and its children in a set will cause duplicates in the serialized string. 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. Ajax forms are the integral part of web technology today. It makes sending HTTP requests very easy, no page reloads and it's fast, it can send-receive information in a various formats such as HTML, JSON or XML. Let's learn various ways to send HTML form data using jQuery Ajax. Browser Support. 11+ 29+ 46+ 9.1+ 38+ Simple HTML Form Submit. The form data is placed into a variable by using the jQuery serialize method. This method forms a key-value query string by taking all of the form input names, as well as their values. This string can then be parsed by the server-side script for further processing. The final bits of code is to use $.ajax to submit the form to the server.

I have a jQuery ajax function and would like to submit an entire form as post data. We are constantly updating the form so it becomes tedious to constantly update the form inputs that should be sent in the request.

There's a function that does exactly this:

serialize() is not a good idea if you want to send a form with post method. For example if you want to pass a file via ajax its not gonna work.
Suppose that we have a form with this id : 'myform'.
the better solution is to make a FormData and send it:

In general use
serialize() on the form element.
Please be mindful that multiple <select> options are serialized under the same key, e.g.
will result in a query string that includes multiple occurences of the same query parameter:
which may not be what you want in the backend.
I use this JS code to reduce multiple parameters to a comma-separated single key (shamelessly copied from a commenter's response in a thread over at John Resig's place):
which turns the above into:
In your JS code you'd call it like this:
Hope that helps.

Use
Serialize a form to a query string, that could be sent to a server in an Ajax request.

A good jQuery option to do this is through FormData. This method is also suited when sending files through a form!
Your send function in jQuery would look like this:
to add data to your form you can either use a hidden input in your form, or you add it on the fly:

You just have to post the data. and Using jquery ajax function set parameters. Here is an example.

The other solutions didn't work for me. Maybe the old DOCTYPE in the project I am working on prevents HTML5 options.

I'm trying to send a form's data using jQuery. However, data does not reach the server. Can you please tell me what I'm doing wrong?
My HTML form:
JavaScript (in the same file as the above form): Server side PHP (/getcontact.php): Can you please tell me what I am doing wrong? UPDATE
Checked
var_dump($_POST) and it returned an empty array.
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.
Winmend folder hidden free download. I don't see how this would be a server configuration problem. Any ideas?
Thank you!

You can use this function
return type is json
EDIT: I use
event.preventDefault to prevent the browser getting submitted in such scenarios.
Adding more data to the answer.
dataType: 'jsonp' if it is a cross-domain call.
beforeSend: // this is a pre-request call back function
complete: // a function to be called after the request ends.so code that has to be executed regardless of success or error can go here
async: // by default, all requests are sent asynchronously
cache: // by default true. If set to false, it will force requested pages not to be cached by the browser.

use serializeArray and add the additional data:

Have you checked in console if data from form is properly serialized? Is ajax request successful? Also you didn't close placeholder quote in, which can cause some problems:

Have you looked in firebug if POST or GET?.
check the console display.
Put in the test script:
You can see the response from the server, if it shows something.

The problem can be PHP configuration:
Please check the setting max_input_vars in the php.ini file.
Try to increase the value of this setting to 5000 as example.
Then restart your web-server and try.

Jquery Ajax Serialize Form Data Example Mvc
See the answer from this previous post. Than you can use .post() or .get() to send serialized data to server.
Anyway, it is very confusing your situation caused by this lack of details.
If you're using a web server (non-local) this code can be wrong if you forget to setup the actual jquery link. I don't know even if you refer jquery on absolute path or relative path!?
