php - jquery function is not sending the value on page load -


i'm sending value from jquery function body, seems jquery not sending value. want fire following jquery function when page loads:

 <!doctype html>     <html>     <head>         <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>    <script type="text/javascript" src='http://cdn.bitbucket.org/pellepim/jstimezonedetect/downloads/jstz-1.0.4.min.js'></script>         <script>             $(document).ready(function(){                   var tz = jstz.determine(); // determines time zone of browser client                  jquery('body').load('index.php?session_name='+tz.name());             });         </script>      </head>     <body>

index.php:

<?php session_start();  if (isset($_get['session_name'])) {$_session['session_name'] = $_get['session_name'];}  echo $_session['session_name'];

.............. ..............

php get gets value url, when use jquery.load, page has data url not have get request data, due which, session never set.

if want set session in way, redirect page url want , session set.

so, instead of doing this:

jquery('body').load('index.php?session_name='+tz.name());

redirect page values:

window.location = 'index.php?session_name='+tz.name();

the better way using jquery send request page asynchronously don't have reload page.

the ajax way @ simplest:

$.ajax({   type: "post",   url: "index.php",   data: { session_name: tz.name() } }).done(function( msg ) {  // alert( "session saved: " + msg );   console.log(msg); });

and php:

if (isset($_post['session_name'])) {$_session['session_name'] = $_post['session_name'];}  echo $_session['session_name'];
