how to pass javascript jQuery variable value in php array

Question

For example

var dirnm = jQuery.trim($('#dirname').val());
var parent1 = jQuery.trim($('#parent').val());

var url = '<?=$this->url(array('controller'=>'index','action'=>'dirnameex','dirname'=>dirnm ,'parent'=>parent1))?>';

dirnm and parent1 are a ajax variables. So I want to pass dirnm and parent1 to a php array.

this wont work JavaScript is executed in the browser and PHP executed on the server - you need to POST the variables from JavaScript to PHP and dirnm and parent1 are JavaScript variables on AJAX variables ... AJAX is a technique not a language — Manse

This wont work as JavaScript is executed in the browser and PHP executed on the server .. so the PHP would be executed before the page is loaded in the browser and the JavaScript executed ....

What you could do is POST the variables to PHP :

var dirnm = jQuery.trim($('#dirname').val());
var parent1 = jQuery.trim($('#parent').val());
$.post("sript.php", { dirname: dirnm, parent: parent1 } );

then in PHP (script.php) :

// get the variables from $_POST
$dir = $_POST['dirname'];
$par = $_POST['parent'];
$this->url(array('controller'=>'index','action'=>'dirnameex','dirname'=> $dir,'parent'=> $par))

Docs here for $.post() (jQuery) and Docs here for $_POST (PHP)

php runs server side, javascript runs client side so you can't do that.

You can pass the variables to php using ajax. but this would be a seperate thread.
