[RESOLVED] PHP Code Not Working after Server Reload

[webzila]

Hello,

A friend of my rents a server and hosts my site. This past week he reinstalled the OS on the server and went from Red Hat to CentOS. Anyways, after the reinstall I started restoring some files and I have noticed that the PHP code for the website navigation/menu does not work anymore. The code has not changed and it has been working fine for over 3 years..

Here is an example of one of the sites that does not work:
http://htmlbasics.webzila.com

Here is the code that drives the navigation (located in index.php):

<?php	
							if (!isset($wz)) { $wz="home"; }
							switch ($wz) {
								case "home": include("home.php"); break;
								case "intro": include("intro.php"); break;
								case "colors": include("colors.php"); break;
								case "16colors": include("16colors.php"); break;
								case "hexcolor": include("colorchart.php"); break;
								case "fonts": include("fonts.php"); break;
								case "images": include("images.php"); break;
								case "tables": include("tables.php"); break;
								case "frames": include("frames.php"); break;
								case "forms": include("forms.php"); break;
								case "audio": include("audio.php"); break;
								case "wavexample": include("wavexample.php"); break;
								case "racontrols": include("racontrols.php"); break;
								case "links": include("links.php"); break;
								case "layout": include("layout.php"); break;
								case "misc": include("misc.php"); break;
								case "redirect": include("redirect.php"); break;
								case "ooops": include("ooops.php"); break;
								case "thankyou": include("thankyou.php"); break;
								case "questions": include("questions.php"); break;
								case "comments": include("contact.php"); break;
								case "about": include("about.php"); break;
								case "forums": include("forum.php"); break;
								case "slinks": include("misclinks.php"); break;
								case "meta": include("meta.php"); break;
								case "linkchecker": include("linkframe.php"); break;
							}
						?>

So when you select a link from the menu such as "Intro" the URL is ?wz=intro.php -- you can see that it puts that in the address bar but it does not display the intro.php file on the screen - instead it just reloads home.php

This has to be a setting on the server because I tried uploading to a different server and it works fine but I have no idea what to check for.

PHP version on the server is: 4.3.9

Please help....

I suspect register_globals was turned on before, and now it's been turned off (which is the default for all the current versions of PHP now). You could either have it turned back on, or to make your scripts more robust and portable, access variables via the $POST or $GET arrays as applicable. For instance, you could start the above script as:

<?php    

                            $wz = (!isset($_GET['wz'])) ? $_GET['wz'] : "home";
                            switch ($wz) {

PS: some more info on the register_globals subject you might want to read before making up your mind what to do: http://www.php.net/register_globals

I will check the register_globals
However I have tried modifying the code as you suggested and it still doesnt work.
I replaced the beginning of the script with the code you recommended..like this:

<?php	
							$wz = (!isset($_GET['wz'])) ? $_GET['wz'] : "home";
                            switch ($wz) {
								case "home": include("home.php"); break;
								case "intro": include("intro.php"); break;
								case "colors": include("colors.php"); break;
								case "16colors": include("16colors.php"); break;
								case "hexcolor": include("colorchart.php"); break;
								case "fonts": include("fonts.php"); break;
								case "images": include("images.php"); break;
								case "tables": include("tables.php"); break;
								case "frames": include("frames.php"); break;
								case "forms": include("forms.php"); break;
								case "audio": include("audio.php"); break;
								case "wavexample": include("wavexample.php"); break;
								case "racontrols": include("racontrols.php"); break;
								case "links": include("links.php"); break;
								case "layout": include("layout.php"); break;
								case "misc": include("misc.php"); break;
								case "redirect": include("redirect.php"); break;
								case "ooops": include("ooops.php"); break;
								case "thankyou": include("thankyou.php"); break;
								case "questions": include("questions.php"); break;
								case "comments": include("contact.php"); break;
								case "about": include("about.php"); break;
								case "forums": include("forum.php"); break;
								case "slinks": include("misclinks.php"); break;
								case "meta": include("meta.php"); break;
								case "linkchecker": include("linkframe.php"); break;
							}
						?>

Now when you go to the website it doesnt display the home.php by default so all it shows it just blank space where a page should be. Then when you select anything from the menu it once again goes to home.php instead of the page it should be displaying.

My bad: I got my logic inverted in the first statement. Just delete the "!" from before the isset() call, and I think you'll be OK (I hope).

Thank you!!!
That worked...the menu options are working as before now.
