Using mysql, apache and win98
The following code is from "PHP, mySQL and Apache" (SAMS) by Julie Meloni.
Page 338-339 (hour 16).
After choosing my selections in the form box and hitting submit I get: ...............
Warning: Invalid argument supplied for foreach() in c:\apache\htdocs\listing16.5.php on line 13 ..................
[ snip ]
// script 16.5.php <html> <head> <title>Listing 16.5 Accessing session variables</title> </head> <body> <h1> Content Page</h1> <?php if (isset($_SESSION[products])) { print "<b>Your cart:</b><ol>\n"; foreach (unserialize($_SESSION[products]) as $p) { print "<li>$p"; } print "</ol>"; } ?> <a href="listing16.4.php">Back to product choice page</a> </body> </html>
you are missing session_start(); on 16.5 You need that in order to populate the $_SESSION array.
