can somebody explain this if/else statement?? it's got the ?: version of it...

It's a login/pw check, and I just want to understand the if/else order, and how it works here...

 

<CODE>

 

$loginUsername=$_POST['email'];

$password=$_POST['password'];

 

$LoginRS__query=sprintf("SELECT member_email, member_password FROM members WHERE member_email='%s' AND member_password='%s'",

    get_magic_quotes_gpc() ? $loginUsername : addslashes($loginUsername), get_magic_quotes_gpc() ? $password : addslashes($password));

 

</CODE>

 

Thanks!

Its simple.

 

<?php echo $expression ? 'true' : 'false' ?>

 

If $expression equals true, true will echo, otherwise false will echo.

In psuebo

if magic quotes are turned on use $loginusername otherwise add slashes to it

same with the password.

So if magic quotes are anabled on your server you'll get equivalent of:

 

$LoginRS__query=sprintf("SELECT member_email, member_password FROM members WHERE member_email='%s' AND member_password='%s'",$loginUsername,$password );

 

and if they're disabled you get:

$LoginRS__query=sprintf("SELECT member_email, member_password FROM members WHERE member_email='%s' AND member_password='%s'",addslashes($loginUsername),addslashes($password));
