Chapter 9: Question
octavian replied to AlexBeau's topic in PHP for the Web: Visual QuickStart Guide (4th Edition)
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 <?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: $msg = '<p>Your settings have been entered! Click <a href="view_settings.php">here</a> to see them in action.</p>'; } // End of submitted IF. ?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Customize Your Settings</title> <style type="text/css"> body { <?php // Script 9.2 - view_settings.php // Check for a font_size value: if (isset($_POST['font_size'])) { print "\t\tfont-size: " . htmlentities($_POST['font_size']) .
