[SOLVED] URL regex help

[doug007]

Hi Lads,

 

On my url i have this path:

 

index.php?cPath=3_16

 

i am using this code to match "3_16"

$cPath = $HTTP_GET_VARS['cPath'];
	$pattern = "/[1-9_1-9]/";
	if(eregi($pattern, $cPath))
		{
			echo $cPath;
			}

 

but it is not working, what am i missing?

 

cheers

Square brackets delineate character classes: a pool of characters from which only one is picked. [1-9_1-9] is equivalent to [1-9_], which will only match 1, 2, 3, 4, 5, 6, 7, 8, 9, or _. You want something along the lines of /\d+_\d+\z/, which requires preg_match. The ereg would be [0-9]+_[0-9]+$.

men am i happy to see you effigi

 

ok,

 

i tried the below, but still no joy:

 

$cPath = $HTTP_GET_VARS['cPath'];
	$pattern = "/\d+_\d+\z/";
	if(eregi($pattern, $cPath))
		{
			echo $cPath;
			 }

ohh damn...sorry i did not read your full post....

 

i think you meant this:

 

$pattern = "/^[0-9]+_[0-9]+$/";
	if(preg_match($pattern, $cPath, $matches))

		{
			var_dump ($matches);
			 }

 

i am testing it now.....

You have two choices:

 

1. preg_match('/\d+_\d+\z/'...

2. eregi('[0-9]+_[0-9]+$'...

 

Also, note that I've included 0's, which you may or may not want.

 

is there anything you don know ?

 

Assuming you mean "don't know," yes; there's plenty.
