i think there is some Can someone guide me please?

waning message is this

Warning: mysql_result(): Unable to jump to row 0 on MySQL result index 2 in /var/www/login/loginform.php on line 24

You really should fix whatever's causing the warning, but you can hide / show errors with error_reporting. To hide warning messages, you could use something like this:

error_reporting(E_ERROR | E_PARSE);

Edit your PHP.ini file :

Set these two lines as :

   display_errors = Off
    display_startup_errors = Off

You must fix your code rather turning it off. If you want to off warnings you can set it in php.ini of your server. Set

error_reporting = E_ALL & ~E_NOTICE

I recommend doing this globally is not a good idea. So do it in your project using PHP. To do this you can use PHP function

error_reporting(E_ALL ^ E_NOTICE);

Put this function before where your code starts execution.
