Hi Leo, Actually I do this with preg_replace().
A code might like this: --- begin code --- // if url taken from browser url address $querystring = $_SERVER['QUERY_STRING']; $newurl = preg_replace('/(var1)=([0-9].*)&(.*)$/', '\1=20&\3', $querystring ); // if url taken from string $url = http://www.foo.com/test.php?var1=20&var2=10 list(, $querystring) = explode('?', $url); $newurl = preg_replace('/(var1)=([0-9].*)&(.*)$/', '\1=20&\3', $querystring ); --- end code --- Good Luck, Firman ----- Original Message ----- From: "Leo Divinagracia" <[EMAIL PROTECTED]> Cc: "[PHP-WIN]" <[EMAIL PROTECTED]> Sent: Tuesday, March 16, 2004 8:35 PM Subject: [PHP-WIN] help with _PHP_SELF and changing a paramter in URL... > sorry, it's late gotta get some sleep, but this had been stumping me... > > have to change a value in the URL, say: > > www.foo.com/test.php?var1=10&var2=10 > > i want to make that a clickable link but set var1 = 20. i'm getting > tired so i may not be searching php.net correctly... > > would i EREGI_REPLACE it or some other way? > > the link i want to set it is > > www.foo.com/test.php?var1=20&var2=10 > > thanks... > > -- > Leo G.
