Remove variable from $_SERVER['QUERY_STRING']

PoorDoggie · 01-29-2006, 12:14 PM

I need to remove the variable $m from my querystring... the querystring is variable, and $m is never always in the same place, and never the same variable.

I want to make a link from search.php?m=blah&q=blah2 etc... to search.php?m=something_else_now&q=blah2 < same again. Now, there could potentially be hundreds of variables in my querystring, and $m could be anywhere in there, so I can't just take the first x letters off. Also the value of $m varys in length depending on the the user's preferences.

Is there any way I can take the $m value out of the querystring?

Thanks
Tom

Hey, I put my mind to it, and I got it!

if anyone wants the code: here it is:

PHP Code:

  $querystring = explode("&",$_SERVER['QUERY_STRING']);

                $qs_nos = 0;

                

                $qs_final = "?";

                while(isset($querystring[$qs_nos])){

                  if(!ereg("m=",$querystring[$qs_nos])){ // change the "m=" to "var_to remove="

????: NamePros.com http://www.namepros.com/programming/162635-remove-variable-from-_server-query_string.html
                    $qs_final .= $querystring[$qs_nos]."&";

                  }

                  $qs_nos++;

????: NamePros.com http://www.namepros.com/showthread.php?t=162635
                }

$qs_final is the variable that holds the new querystring with your var removed!

alternatively you could do the following:-

PHP Code:

  $name_of_varialbe = 'b';

????: NamePros.com http://www.namepros.com/showthread.php?t=162635
unset($_GET[$name_of_varialbe]);

$string = '?';

$counted = count($_GET);

$count = 0;

foreach ($_GET as $key=>$value)

{

    $string .=$key.'='.$value;

    $count++;

    if ($count!=$counted)

    {

        $string .= '&';

    }

}

$name_of_varialbe is the variable which will hold the name of the variable you wish to be removed. $string is the result string after it has been removed.

that maybe better for me, as it won't accidentally cut a string in half if the user uses a "m=" in the middle of a string (as if... lol - better safe than sorry)
