I have recently followed a video on YouTube of how to make a fully operational login system but I for some reason get an error that isn't in the video???
Here is the error message I am getting:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/a9994826/public_html/login.php on line 15
Here is line 15:
$numrows = mysql_num_rows($query);
Can anyone help be figure this out??
