Call to a member function real_escape_string() on a non-object when using MySQLi

Question

I have tried every solution posted on other questions about this topic, but none of them work.

I\'m sorry if this is a basic question, but I\'m new

Answer 1

Currently, $connect is out of scope, just add it in the parameter:

$connect = new mysqli('localhost', 'shop', 'password', 'zen');
function cleanInput($connect, $string = '') {
    if(!empty($string)) {
        $stripsql = $connect->real_escape_string($string);
        return $stripsql;
    }
}
$my_string = 'your string here';
$escaped_string = cleanInput($connect, $my_string);

Sidenote: Or if you can, you can also use prepared statements.
