Answer 1

also, to use the function mysqli_real_escape_str, you need the mysqli , to get it

function get_mysqli() { 
$db = (array)get_instance()->db;
return mysqli_connect('localhost', $db['username'], $db['password'], $db['database']);}

The above function returns a mysqli object such that you can use,

$escaped = mysqli_real_escape_string(get_mysqli(),$string);

It works well, not so important here though!
