passing variables via url in PHP 4

peters1977

I am creating a simple page with several links. Each link has a different value such as:

How can I retrieve this variable on the next page? I've been trying to figure it out, but somehow it doesn't work right.
I have about 10 links with different variables, and what happens is that systems_by_subnet.php?net=1722810 displays values for all of the links.

Help!!!

Thanks

Ok, I made this just so I would know EXACTLY how it was done... and so I could make sure to use it perfectly correct...

$query = $QUERY_STRING;
$query_Array = explode("&", $query);
foreach ($query_Array as $i) {
$doubleItem = explode("=", $i);
$$doubleItem[0] = str_replace("%20", " ", $doubleItem[1]);
}

Might look a bit confusing but its not, trust me. 🙂

Anyways, put this at the top of the script and it will return the variable with the value...

so like you said... if you had...

systems_by_subnet.php?net=1722810

this would return.. the variable "$net" with the value of 1722810

See? Not bad (put this in the page that is going to use those addresses...)

There is one problem with it. Even though the variable shows up as net=1722810, when I get this variable using
$_GET[net];
i see /1722810/
For now I was able to strip it, but it was unexpected.

Thanks for you help

Well, maybe use
$_GET['net'];
?

I never had such problems with slashes when accessing the $_GET array.

Of course if you really need to then use:
$net = trim($_GET['net'], '/');
