Answer 1

As per the documentation, you are using the variant which requires a connection variable to be passed as an argument:

string mysqli_real_escape_string ( mysqli $link , string $escapestr )

The object-oriented style (with one parameter) is performed on a connection variable thus (from the same page linked to above):

$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$city = $mysqli->real_escape_string($city);

Answer 2

try this return mysqli_real_escape_string ($conection,$string);

mysqli_real_escape_string need two parameter, $connection variable is the variale which you uses to connect with the database, you might have to change this with your original variable
