Question

I’ve seen many questions like this on stack overflow, but I want to know why my code won’t work. It makes perfect (logical) sense. Can anyone please explain to me what code I would have to write to actually complete the if statement I have in mind?

$result = mysql_query("SELECT confirmed FROM usernames WHERE username = '$username' AND password = '$password'")
if ($result==NULL)
echo 'Failure';

I’m attempting this in php.

NOTE:

confirmed in the DB is set to NULL, so the final echo should display.

The variable $result contains an internal representation of the result of the query (as returned by the mysql_query() function). To get the actual value you need to use another function, like mysql_fetch_assoc() or mysql_result(). Kind of like this:

$result = mysql_query("SELECT confirmed FROM usernames WHERE username = '$username' AND password = '$password'");
$conf = mysql_result($result, 0, 0);
if ($conf == NULL){
    echo 'Failure';
}
