Handling Laminas Forms with Dependencies - the view results

If only the select element needs entries from a database then you can create a separate form element with the required dependencies.

  1. Create the element:

    class CountrySelectElement extends Laminas\Form\Element\Select
{
    // …

    public function init()
    {
        $this->setName('country_id');
        $this->setLabel('Countries');
        $this->setValueOptions($categories->fetchAllCountries());
        // …
    }
}

  2. Create a factory for the element.

  3. Register the new element:

    return [
    'form_elements' => [
        'factories' => [
            CountrySelectElement::class => CountrySelectElementFactory::class,
        ],
    ],
    // …
];

  4. Usage in a form:

    class MyForm extends Laminas\Form\Form
{
    public function init()
    {
        $this->add(['type' => CountrySelectElement::class]);
    }
}

This allows the element to be reused without factories for forms.
