i have an if statement but i need to use the oppsite of isset like isn'tset only i know that isn't right is it like !isset or isset! or somthing totaly different
The isset() function returns a boolean. So it is either true or false.
When you test using if (isset(xxx)) your action is performed on the true result of the isset.
When you test using if (!isset(xxx)) your action follows the true result of the NOT isset.
Hope this is clear. So the answer is: test with !isset(xx)
