Check link page url

[hlstriker]

Hi, I am trying to find the pages url then see if it contains a certain string.

 

Here is the code I used but doesn't work.

<? 
$link = $_SERVER["PHP_SELF"];

$exp = explode("=", $link);
$linkname = $exp[0];
$linknumber = $exp[1];

if($linkname == "/viewpage.php?page_id")
{
echo $linkname;
echo $linknumber;
}
?>

 

What I'm trying to do is see if "$_SERVER["PHP_SELF"]" contains a certain page. If it contains "/viewpage.php?page_id" I want it to go into that if statement. The problem is it doesn't

 

Btw I need it to explode it because I need the page id number in the other variable for something later.

 

Also another problem is if the link doesn't contain the "=" sign to explode. Would that cause a problem?

For debugging purposes, why don't you try printing the values of $linkname and $linknumber before you get to the "if" block?

Already checked that and it works. Now I just need to know if the explode will work on a page without a = sign. or will that cause errors?

Also I found out the "$link = $_SERVER["PHP_SELF"];" only will contain "/viewpage.php"

 

I need it to also get the "?page_id=x" part that comes after "/viewpage.php". how can I do this?

 

Thanks
