Using multiple valueFields in find('list')

问题

Trying to use multiple fields in my find method -

$users = $this->AdressesUsers->users->find('list', [
            'keyField' => 'id',
            'valueField' => ['firstname','lastname'],            
        ]);

Works, kinda. Because the two get seperated by a semicolon. Also tried using a mutator method, but this failed badly.

In my Function

'valueField' => function ($e) {
        return $e->author->get('full_name');
    }

In my Entity User

protected function _getFullName()
    {
        return $this->firstname . '  ' . $this->lastname;
    }

I would never mess with the entity, keep it without logic and as simple as possible.

A better approach here is to use what you already tried:

'valueField' => function ($e) {
    return $e->first_name . ' ' . $e->last_name . ' ' . $e->more;
}

etc Just debug() the entity here and you will see that it contains the whole data set and you can put it together however you like.

I'd suggest you to use Queries As Collection Objects here. Try this:

$users = $this->AdressesUsers->Users->find()
              ->map(function ($row) { // map() is a collection method, it executes the query
                  $row->fullName = $row->firstname . ' ' . $row->lastname;
                  return $row;
               })
               ->combine('id', 'fullName') // combine() is another collection method
               ->toArray(); // Also a collections library method

pr($users);  // Check your result

you can use virtual field just like normal field,

$this->AdressesUsers->users->find('list', [
    'keyField' => 'id',
    'valueField' => function ($e) {
           return $e->full_name;
    }
]);

Additional you can also return array in valueField,

$this->AdressesUsers->users->find('list', [
    'keyField' => 'id',
    'valueField' => function ($e) {
        $d=[];
        $d['firstname'] = $e->firstname;
        $d['lastname'] = $e->lastname;
        return $d;
    }
]);
