Select2 initSelection

Question

I have a problem to set the method initSelection with an ajax call, I returns \"undefined\". I checked and the ajax call returns the correct result .. I donot understand the

Answer 1

Here the way to solve:

initSelection: function(element, callback) {

        return $.ajax({
            type: "POST",
            url: path,
            dataType: 'json',
            data: { id: (element.val())},
            success: function(data){

            }
        })

care must be taken that the array is created in the controller and it should be something like this:

foreach ($entities as $member) {
        $json['id'] = $member->getId();
        $json['name'] = $member->getComune();
        $json['region'] = $member->getRegione()->getRegione();
        $json['prov'] = $member->getProvincia()->getSigla();
}

        $result = $json;
        return json_encode($result);
