PHP mysqli_real_escape_string returning empty string

Question

The code works fine if I don\'t use the mysql_real_escape_string function. But the function is returning nothing! I read that the problem may be due to the fact that I do no

Answer 1

php.net says
Procedural style
mysqli_real_escape_string ( mysqli $link , string $escapestr )
So you will need to add your $con to it:
$title = mysqli_real_escape_string($con, $_POST["title"]);
