How to pass all GET variables using PHP_SELF?

[hatrickpatrick]

In my script, there are a few variables I want passed from one page to another, and rather than do the long winded "if isset" method for all of the links on the page, I've heard there is a global variable which basically puts them all into the ?var1=value&var2=value etc format... Anyone know which variable that is? PHP_SELF only passes the filename...

You'll probably want to look at $_SERVER['QUERY_STRING']. This variable holds all the query strings being passed to the page:

echo $_SERVER['PHP_SELF'] . '? ' . $_SERVER['QUERY_STRING']

;

Excellent, that works - just one more problem, is there a variable which gives you JUST the filename? PHP_SELF gives ou the directory as well...
