Hello, I am currently making a one page site using $_get[];. I'm just doing some basic work but I have hit a road block and I can't figure out why my $_get's arn't retrieving data from the url.

The problem is it will just go to the else statement,

Code: Select all: <?php $catt = $_GET[cat] $ider = $_GET[id] $pager = $_GET[page] if ( catt = 0 && ider = 1 && pager = 1 ) { echo "test"; } elseif (catt = 0 && ider = 1 && pager = 2) { echo "test2"; } else { $message = "Sorry - The server cannot find the file or script you asked for. Please check the URL to ensure that the path is correct."; ?> <Center> <?php echo $message; ?> </center> <?php } ?>

What I am doing to retrieve the data from the url is

index.php?cat=0&id=1&page=1

Thanks.

Hmm, should they not be written like this?

Code: Select all: $catt = $_GET['cat']; $ider = $_GET['id']; $pager = $_GET['page'];

Whoops, Forgot to add them

.

although I still receive the same problem, even after readjusting the vars.

If you referring to the variables here should they not be given dollar signs?

Code: Select all: if ( $catt = 0 && $ider = 1 && $pager = 1 ) { echo "test"; } elseif ($catt = 0 && $ider = 1 && $pager = 2) { echo "test2";

My PHP is quite basic so I'm just going by what I think at the moment.

Ah, I found my problem. I just turned globals on (Forgot they were off) and removed the get and changed the equal signs and it decided to start working.

Code: Select all: if ($cat == "0" & $id == "1" & $page == "1" ) { echo "test"; } elseif ($cat == "0" & $id == "1" & $page == "2") { echo "tests2"; } else { $message = "Sorry - The server cannot find the file or script you asked for. Please check the URL to ensure that the path is correct."; ?> <Center> <?php echo $message; ?> </center> <?php } ?>

Thanks for the responses Blink.

NEVER WRITE A SINGLE LINE OF PHP WITH GLOBALS ON.
Its evil, a security risk, and will cause most scripts to fail (like phpbb, cmsses)
dont ever use it, learn to work without it. You'll thank me later.

besides that:
the and operator takes two &&. One & is a bitwise operator, which does something completely different.

quick php echoes are done with shorttags (if enabled)

Code: Select all: <php $test="watermelon"; ?> <html> Hi, this is a <?=$test;?> word </html>

What Zombie said. register_globals MUST be off - it's only still even in PHP to allow backward compatibility with badly written php3-era scripts. In PHP6 (due to launch this year, IIRC) it'll be gone. Forever. For good. Not an option. so get used to coding without it. For your own sake!! it's a recipe for disaster.
