A part of AJAX response storing in PHP variable

I need to store a piece of data, into PHP variable, which is received through AJAX response in an input box. How can I do this?

<script type="text/javascript">
  $(document).ready(function() {

    $("#user_id").change(function() {
      var id = $(this).val();
      var dataString = 'user_id='+ id;

      $.ajax({
        type: "POST",
        url: "wmat_details.php",
        data: dataString,
        cache: false,
        success: function(result) {
          var data = result.split(",");

          $('#name').val(data[0]);
          $('#email').val(data[1]);
          $('#ref_id').val(data[2]);
          $('#candidature_start').val(data[3]);
          $('#candidature_end').val(data[4]);
          $('#default_attempts').val(data[5]);
          $('#existing_complimentary').val(data[6]);
          $('#wmat_start').val(data[9]);
          $('#wmat_end').val(data[10]);
          $('#attempts_taken').val(data[11]);
        }
      });
    });
  });
</script>

As shown in above code, I want to store $('#attempts_taken').val(data[11]); this value to a PHP variable. Any insight is appreciated.

You cannot store ajax response into a php variable.

way 1 :

You can make another ajax call.

way 2 :

you can set session.

Unfortunately you can't.

PHP is server side while jQuery (JS) is client side. They are two separate layers of abstraction that interact only when the client call the server.

I don't have enough informations about what you need to do with data[11] but it seems that you have only one option: make a consecutive AJAX call to the php file that will manipulate data[11].

The consecutive AJAX call must be executed from inside the first call success callback; something like this:

success: function(result){
     // Your on success logic
     // ...
     // Prepare the object to send to the server
     var objData = {};
     objData.attemptsTaken = data[11];
     // Execute the second AJAX call to the server
     $.ajax({
         type: "POST",
         url: "second_call_destination_file.php",
         data: objData,
         success: function(result){
             // Do something on success
         },
         error: function(){
             // Do something on error
         },
         complete: function(){
             // Do something on complete (executed after success and error)
         }
}
