Hi! I am a pre-newbie in PHP, and I'm writing my first script. I have innstalled phpdev 423, and started Apache, php, mysql and all. I use Dreamwiever MX for my "writing"  I have bought a book (PHP for webprofessionals, Crhistopher Cosentino), and I just type one of the first, simple script. But I can't get the results of my variables to show up in the browser. Here is what I do: FILE 1: form_entry: <html> <head> <title>Legge informasjon i et skjema</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <form action="form_results.php3" method="get"> <p>First name: <input type="text" name="first_name"> <br>Last name: <input type="text" name="last_name"> <br>Address: <input type="text" name="address"> <br>City: <input type="text" name="city"> <br>State: <input type="text" name="state"> <br>Zip: <input type="text" name="zip"> <br>Home phone: <input type="text" name="home_phone"> <p><input type="submit" name="Submit"> <input type="reset"> </form> </body> </html> FILE 2: form_results.php3 <html> <head> <title>Skjema</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <h2>Here is what you typed</h2> <?php print ("<p>First Name: <b>$first_name</b>\n"); print ("<br>Last Name: <b>$last_name</b>\n"); print ("<br>Address: <b>$address</b>\n"); print ("<br>City: <b>$city</b>\n"); print ("<br>State: <b>$state</b>\n"); print ("<br>Zip: <b>$zip</b>\n"); ?> </body> </html> And, the result (in my browser), when I type in my name, address and more...: Here is what you typed First Name: $first_name\n"); print (" Last Name: $last_name\n"); print (" Address: $address\n"); print (" City: $city\n"); print (" State: $state\n"); print (" Zip: $zip\n"); ?> Does anybody see where I am doing wrong? -- mvh Jan Vidar www.janvidar.com | ||

In newer versions of PHP, register_globals is by default turned off. Which means that you whatever variables you submit to your script aren't directly visible, you have to access them using the $_GET/$_POST/$_REQUEST arrays, which contain all of the GET/POST/both GET and POST variables, respectively. If you expect a variable called first_name to be available in your script, try checking $_REQUEST["first_name"]. You'll probably find it there. Do a Google search for register_globals for more info. Lykke til! -- Marius | ||

How will this work on a server that uses register_globals OFF? Do I have to rewrite all my previous php-scripts? -- mvh Jan Vidar www.janvidar.com | ||

Do I have > to rewrite all my previous php-scripts? $_POST[$varname] will work whether register_globals is OFF or ON. Also, $_POST, $_SERVER, $_GET, etc are accessible within functions, without having to declare them as global | ||
