Missing argument 1 for page::sponsor()

Question

i'm having this really frustrating error. I'm calling the sponsor function from another function and pass an argument. The sponsor function however keeps giving the missing argument error.

here's my code:

// get random sale
public function RandomSale() {
    static $sale = null;
    if(!isset($sale)){
        $sale = Sale::get()->filter(array('Title:not' => null))->sort("RAND()")->Limit('1');
        $this->sponsor(8);
    }
    return $sale;
}

public function sponsor($memberid) {
    $sponsor = Sponsor::get()->filter(array('MemberID' => $memberid))->Limit('1');
    return $sponsor;
}

how can i fix this?

Answer 1

Try naming your sponsor() function to something more specific, like SponsorByID($memberID). You may have a naming conflict between your Sponsor DataObject and your sponsor() function.
