Hi Group Members
i have a problem with function empty() i use it to check if user entered the form fields and store it in array
for example :
if (empty($Game_rating)) $errors[] = "You didn't enter the Online Status for the Game.";
the problem when the user enters 0 in the form field the empty function returns the error.
Is $Game_rating supposed to be an integer? If so, then make it one and check for <= to zero.
if(!isset($_Game_rating) || (int)$Game_rating <= 0)
{ $errors[] = "You didn't enter the Online Status for the Game."; }Now you _know_ $Game_rating is an integer above zero and is safe to display and/or put into a query.
Simply checking for
if($Game_rating == '')
will throw notices on some setups about an undefined variable (depending upon error_reporting level) and will allow text through when it's supposed to just be an integer.
