Use Component from Form

Question

I would like to pass request-data to this form-class to validate generic information. I've implemented a component (outsourced for reusability) to bring address data into required model format.

namespace App\Form;

use Cake\Form\Form;
use Cake\Form\Schema;
use Cake\Validation\Validator;

class Foo extends Form {
    protected function _buildSchema(Schema $schema) {
        return $schema
                    ->addField('foo', 'string')
                    ->addField('bar', 'string');
    }
    [...]
    protected function _execute(array $data) {
        // How is it possible to use component-method here?
        // e.g. $this->MyAddressComponent->saveData($data);
        return true;
    }
}

Has anyone an idea what I have to do?

Thanks in advance!

Make your form accept the component in the constructor:

namespace App\Form;

use App\Controller\Component\MyAddressComponent;

class Foo extends Form {

    private $addressComponent;

    public function __constructor(MyAddressComponent $addressComponent)
    {
        $this->addressComponenent = $addressComponent;
    }

    ...

    protected function _execute(array $data) {
        $this->addressComponent->saveData($data);
        return true;
    }
}

Then instantiate the form from the controller as follows:

public function doStuff()
{
    $form = new Foo($this->MyAddressComponent);
    ...
}
