Answer 1

The array $d contains values of mixed types. One of the values is a string (a kind of model name, according to your comment: "model" => "models\BackendSportartenAendern").

Thus the error: you're trying to use the string as if it were a (sub-)array.

One easy way to fix the code is to modify your loop so that non-array values are skipped:

foreach($d as $k => $v) {
    if (!is_array($v)) {
        continue;
    }

    \sys\CDatabase::query(...);
}
