I'am making a message system with only username and password. I use a old script but when i remove this line:

if(preg_match('#^(([a-z0-9!\#$%&\\\'*+/=?^_`{|}~-]+\.?)*[a-z0-9!\#$%&\\\'*+/=?^_`{|}~-]+)@(([a-z0-9-_]+\.?)*[a-z0-9-_]+)\.[a-z]{2,}$#i',$_POST['email']))

i receive this error:


Parse error: syntax error, unexpected 'else' (T_ELSE) in .....\message\sign_up.php on line 66

If i don't remove this line i'll get the message on the signup page like:


Notice: Undefined index: email in ....\message\sign_up.php on line 30
The email you entered is not valid.

include('config.php');

The field for the email is removed already. I want to sign up with username and password only not with email. This is an old script where email is required but i try to remove it. When i remove this line (the email check : if(preg_match('#^(([a-z0-9!\#$%&\\\'*+/=?^_`{|}~-]+\.?)*[a-z0-9!\#$%&\\\'*+/=?^_`{|}~-]+)@(([a-z0-9-_]+\.?)*[a-z0-9-_]+)\.[a-z]{2,}$#i',$_POST['email']))
 
then i receive the error : Parse error: syntax error, unexpected 'else' (T_ELSE) in .....\message\sign_up.php on line 66

Thank u very much, i figured it out. // before the if(preg_match('#^(([a-z0-9!\#$%&\\\'*+/=?^_`{|}~-]+\.?)*[a-z0-9!\#$%&\\\'*+/=?^_`{|}~-]+)@(([a-z0-9-_]+\.?)*[a-z0-9-_]+)\.[a-z]{2,}$#i',$_POST['email']))
