Am i going mad?? Passing $_GET variable

BIOSTALL

I am going insane from trying to figure out what is wrong with my code. I'm bascially trying to pass a variable in a URL and then retrieve it using $_GET but for sum reason its not working.

Heres how i'm setting the variable:

$newstartinglimit = (startinglimit+8);
				$next = "<a href='OtherGigs.php?limit=$newstartinglimit'><img src='ImageNext.gif' height='30' border='0'></a>";

And heres how i'm getting the variable:

$startinglimit = $_GET['limit'];			
			if (($startinglimit=="") || (!is_int($startinglimit))) {
				$startinglimit=0;
			}

But whatever i do... When i echo it out, its always equal to zero.

Anyone help please?? it's driving me insannnneeee

Thank you 🙂 BIOSTALL

in this line.

$newstartinglimit = (startinglimit+8);

startinglimit is missing a $

BIOSTALL

OK.. it's still not working :-S $startinglimit is still equalling zero... even tho in the URL i can see it should be equal to 8 :-S

Any suggestions please??

Thanks, BIOSTALL

of course $startinglimit=0, you are setting the increased value in the variable $newstartinglimit

BIOSTALL

Yeh... but look at the first bit of code i submitted. Then you'll see.

In the URL it's saying http://www.blabla.com/OtherGigs.php?limit=8 but when i do:

$startinglimit = $_GET['limit'];

and then echo $startinglimit its saying limit is equal to 0.

Thats my problem.

BIOSTALL

Ok... i've taken out the:

!is_int($startinglimit)

and it works fine :-S Can anyone see why the number 8 would class as not being an integer?? lol

Thanks, BIOSTALL

$_GET['limit'] is a string containing a number, so is_int returns false. Use [man]is_numeric[/man] instead.

Thank you 🙂

Actually, if you want the functionality of is_int() for a numeric string, you should use [man]ctype_digit/man.

are you printing out the variable after this code?
$startinglimit = $_GET['limit'];

if (($startinglimit=="") || (!is_int($startinglimit))) {
$startinglimit=0;
}

If so, then your if statement is "true" and reseting the variable from 8 to 0. I am not too familiar wth is_int, but you might try is_numeric() instead. Hope that helps.
