Submitting Form using jquery AJAX

问题

I am trying to submit my form using jQuery ajax, but my data isn't posting to PHP it returns empty array nothing in $_POST array.

This is my code - here is my form:

<form action = "/webdevelopmentpakistan/send_mail.php" method = "post" class = "myForm"   >
                <div class="row">
                    <div class="col-md-3 col-sm-12">
                        <div class="form-group">
                            <input class="form-control" id="fname" type="text" required name= "full_name" placeholder="Full Name" 
                             />
                        </div>
                    </div>
                    <div class="col-md-3 col-sm-12">
                        <div class="form-group"> 
                            <input class="form-control" type="tel" required name = "phone" placeholder="+92" id="phone" onkeypress="return isNumberKey(event)" />
                        </div>
                    </div>
                    <div class="col-md-3 col-sm-12">
                        <div class="form-group">
                            <input class="form-control" type="email" required name = "email" id="email" placeholder="Email"/>
                        </div>
                    </div>
                    <div class="col-md-3 col-sm-12">
                        <div class="form-group">
                            <input class="btn popup" type="submit"    name = "submit" value="CONTACT OUR CONSULTANT"/>
                        </div>
                    </div>
                </div>
</form>

its an ajax part:

  $('form').on('submit', function (e) {
    e.preventDefault();

    var url = $(this).attr("action");
    var form_data = $(this).serialize();


    $.ajax({
            type: 'POST',
            url: url,
            data: $('.myForm').serialize() ,
            dataType : 'JSON',
            //contentType: "application/x-www-form-urlencoded",
            success: function (data) { // here I'm adding data as a parameter which stores the response

                    console.log(data); // instead of alert I'm changing this to console.log which logs all the response in console.
            },
             error:function(xhr, textStatus, thrownError, data)
             {
                 console.log("Error: " + thrownError);
                 console.log("Error: " + textStatus);


             }
                   });



    // var popup = document.getElementById("myPopup");
    // popup.classList.toggle("show");
    console.log(form_data);

});

PHP CODE using at other page:

if(isset($_POST)) {
        echo json_encode($_POST);
    }

and this is my serialize array which I am getting on submission of form but it isn't getting passed to php

full_name=talha&phone=012345678&email=admin%40gmail.com

welcome to stackoverflow, here are the changes, hope it will works

$.ajax({
    type: 'POST',
    url: url,
    data: $('.myForm').serialize() ,
    dataType : 'json', // changing data type to json
    success: function (data) { // here I'm adding data as a parameter which stores the response
        console.log(data); // instead of alert I'm changing this to console.log which logs all the response in console.
    }
});

in php

if(isset($_POST)) {
    echo json_encode($_POST);
}

this should print array of post parameters in your console, however you will get an array in php.

The form action needs to be either absolute url i.e. https://somewebsite.com or a relative url on you site so ideally it should be /some-url.php. Read about form action here

So your form opening tag should be,

<form action = "/web-development-in-pakistan.php" method = "post" class = "myForm"  target="_self">

So in your javascript code when you do

var url = $(this).attr("action");

I also believe that in your ajax call, the type needs to be method, so,

$.ajax({
  method: "POST",
  .....
 })
