Assign jquery variable to php variable

Question

I want to assign JQuery variable to the PHP variable. Any idea kindly

<?php    
  $phpvariable = jqueryvariable;    
?>

Answer 1

The restriction is that you are assigning a value from frontend to backend and this can't be done because php runs at server side while js/jquery runs in the browser.

If you are using ajax then you can use the posted value as:

<?php

$phpvariable = $_REQUEST['jqueryvariable'];

?>

Assume this is the posted data in the ajax:

data:{ jqueryvariable:"theDummyVar" }  

or without ajax:

use a <input type="hidden" name="jqueryvariable" value="theDummyVar" /> and post it to the php. This needs to be in the form element.

Answer 2

Why do you need to refer a jquery variable into phpvar? You can just pass the jquery variable via ajax post or you can do it this way.

<?php
$phpvariable = $_POST['textfieldId'];
?>
