    check if field is in GET array? [Resolved]

    There are times that I want to pass certain fields to a page and other times those fields won't be there.

    I want to use those values if they are in the array, but not if they aren't there. But I know from experience that if you check for a key that isn't there, it gives you an error about an invalid variable.

    Is there a way to check this or ignore the error?
