pass client side value to server side variable. **the answer is ajax** — mamdouh alramadan, Mar 02 '14 at 06:10
PHP will run in the server and Javascript in the browser. They're disconected. What you can do is an Ajax request (javascript) that sends what you need back to the server (PHP), processes somthing if needed and returns it, if needed. — D. Melo, Mar 02 '14 at 06:12

Here is an example

AJAX:

var select1 = $("select1").val();
var select2 = $("select2").val();

$.ajax({
   url: 'yourphpfile.php',
   data: {data1 : select1, data2 : select2},
   type: 'POST',
   success:  function(data){
      //do something with the returned data
   }
});

Server-side PHP (yourphpfile.php). To assign a value passed from AJAX, do the following;

$phpselect1 = $_POST['data1']; //should be value of select1 from JS
$phpselect2 = $_POST['data2']; //should be value of select2 from JS

PHP is handled server side (step 1). Javascript is done on the client-side (step 2). You're trying to tell the page to do something on the step that has already been done.

Also, you're trying to assign PHP variables using JS? If you need data to get to PHP, use GET/POST variables and pass relevant data to the PHP upon a page load/refresh.

You are doing it wrong. You need to use Ajax to send a Get or Post request to the server. In that request you can put your variable.
