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. -- ---John Holmes...
