Home Forums Back End undefined index: (problem) Re: undefined index: (problem)


If the array index “terms” doesn’t exist then this error will occur, what you need to do is the following…

if (isset($_GET) && !empty($_GET)) {
$nospaces = substr($_GET, 0, 4);
} else {
// Show an error message!

This will make sure the index exists otherwise it will show an error if you want it to.
