    Chapter 9: Question

    in PHP for the Web: Visual QuickStart Guide (4th Edition)

    Posted

    I did it a little differently. Also here's the code for "Make the form in customize.php sticky, so that it reflects the user's current choices." I'm a total newbie when it comes to this stuff and it took me awhile to figure it out. Some how it works though so :D

    <?php // Script 9.3 - customize.php #2
// Handle the form if it has been submitted:
if (isset($_POST['font_size'], $_POST['font_color'])) {

// Send the cookies:
setcookie('font_size', $_POST['font_size'], time()+10000000, '/');
setcookie('font_color', $_POST['font_color'], time()+10000000, '/');
// Message to be printed later:
$msg = '<p>Your settings have been entered! Click <a href="view_settings.php">here</a> to see them in action.</p>';

} // End of submitted IF.
