I want to store a php $_SESSION variable and retrieve it on another page
<?php
session_start();
// store session data
$_SESSION['count']=0; ?>
<html><head></head>
<body>
<?php include ("getElement.php");
echo getLinkButton("myscript.php", "myscript.php");
echo $_SESSION['count']++; ?>
</body>
</html>
The code above works, but when I click the link to navigate to myscript.php:
<?php
echo $_SESSION['count'];
?>
I get this error: Undefined variable: _SESSION in /home/ubuntu/public_开发者_运维问答html/myscript.php on line 2
Use session_start() in the second page too, before accessing the $_SESSION superglobal array.
myscript.php:
<?php
session_start();
echo $_SESSION['count'];
?>
You must include session_start at the top of all pages you wish to use the session in.
you have to do session_start(); on every page you want to use the session-vars and also be sure you have cookies enabled or send the session-id with every link and form.
