mysqli fetch() wordt niet opgehaald

Het is best grappig wat ik hier probeerde te doen. misschien vanwege overwerk.

Ik heb niets van deze functie geretourneerd, zelfs als mysqli fecth true retourneert.

dus ik wijzig de instructie if($stmt->fetch()){} om een ​​array terug te geven.

if($stmt->fetch()){

        $id =  $this->xss_clean($id);
        $date =  $this->xss_clean($date);
        $name =  $this->xss_clean($name);
        $email =  $this->xss_clean($email);
        $phone =  $this->xss_clean($phone);
        $full_address =  $this->xss_clean($full_address);
        $total_amount_paid =  $this->xss_clean($total_amount_paid);
        $buyers_account_id =  $this->xss_clean($buyers_account_id);
        $sellers_account_id =  $this->xss_clean($sellers_account_id);
        $ad_reference =  $this->xss_clean($ad_reference);
        $transaction_id =  $this->xss_clean($transaction_id);
        $status_by_buyers =  $this->xss_clean($status_by_buyers);
        $status_by_sellers =  $this->xss_clean($status_by_sellers);
        $net_status =  $this->xss_clean($net_status);

        return array(
                $id,
                $date,
                $name,
                $email,
                $phone,
                $full_address,
                $total_amount_paid,
                $buyers_account_id,
                $sellers_account_id,
                $ad_reference,
                $transaction_id,
                $status_by_buyers,
                $status_by_sellers,
                $net_status
                );
    }
