mysqli fetch() ruft nicht ab

Es ist ziemlich lustig, was ich hier versucht habe. vielleicht wegen Überarbeitung.

Ich habe nichts von dieser Funktion zurückgegeben, selbst wenn mysqli fecth true zurückgibt.

Also ändere ich die if($stmt->fetch()){}-Anweisung, um ein Array zurückzugeben.

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
                );
    }
