Sessions...

I have been through 2 different php books and I am yet to sucessfully set and read session variables...

can someone post a basic form that will set 3 session variables in one php form and read them in another php form?...Please

I Am using php Version 5.3.6:

This Will Print The Session Variable just fine in the SessionCookies.php

Code:

 
<html>
<head>
        
 <title>Untitled</title>

</head>
<body>

<?php
session_start();

$_SESSION['FirstName'] = "Jim";

echo ($_SESSION['FirstName']);
echo ($_SESSION['id']);

echo "WOW";
 echo '<a href="SessionReader.php">VIEW </a>';

?>

</body>
</html>

But When I Click The View Link It Only Will display "What"

Code:

<html>
<head>
        
 <title>Untitled</title>

</head>
<body>

<?php
session_start();
echo ($_SESSION['FirstName']);
echo "What";

echo ($_SESSION['FirstName']);


?>

</body>
</html>

Greetings,

Are you using session cookies?

If so then this note applies:

Quote:

Note:
If you are using cookie-based sessions, you must call session_start() before anything is outputted to the browser.

You could try moving the 'session_start' to the top of the script like so:

Code:

<?php
session_start();
?>
<html>
<head>
	<title>Untitled</title>
</head>
<body>

<?php

echo ($_SESSION['FirstName']);
echo '<br />';
echo "What";
echo '<br />';
echo ($_SESSION['FirstName']);

?>

</body>
</html>

Because the:

Code:

<html>
<head>
	<title>Untitled</title>
</head>
<body>

is being sent to the browser before the session is started....

Thank you VERY much. That did the trick! I wasnt aware that the <?php Could exist before the <html tag...
