SQL Num Rows Param/Boolean Error
I have been following these tutorials: http://www.youtube.com/watch?v=FUI2JDaNpk0 but for some reason when I enter the correct password I get this error:
Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /Applications/XAMPP/xamppfiles/htdocs/login.php on line 12

it seems like your mysql_query operation failed. When queries fail they return false, and when they succeed they return a record set. It makes no sense to say mysql_num_rows(false); and that's why you're getting this error.
