Prerequisites

You don’t need any previous knowledge to understand Ajax call, but if you are familiar with following scripting, it will be easy to understand

Here is the standard structure of JavaScript Ajax post in Php.

<script>
$.ajax(
  'make-ajax-call.php',
  {
      success: function(data) {
        alert('AJAX call successful!');
        alert('response from the server' + data);
      },
      error: function() {
        alert('There was some error response from  AJAX call!');
      }
   }
);
</script>

Now let’s look at another example of submitting form using Ajax and jquery in php code.

<script src="jquery-1.9.1.js"></script>
<script>
      $(function () {
        $('#formSubscribe').on('submit', function (e) {
          e.preventDefault();
          $.ajax({
            type: 'post',
            url: 'post-form.php',
            data: $('#formSubscribe').serialize(),
            success: function () {
              alert('form submitted successfully');
            }
          });
        });
      });
</script>
</head>
<body>
    <form id="formSubscribe">
     Name: <input name="txtName" id="txtName"><br>
     Email: <input name="txtEmail" id="txtEmail"><br>
      <input name="submit" type="submit" value="Submit">
    </form>
</body> 

Note: in above code, e.preventDefault() method will block default click handling (it has nothing to do with Ajax form submit, you can take off that line of code), learn more about how preventDefault works
