How can I use laminas-form view helpers?

If you've selected laminas-view as your preferred template renderer, you'll likely want to use the various view helpers available in other components, such as:

• laminas-form
• laminas-i18n
• laminas-navigation

By default, only the view helpers directly available in laminas-view are available; how can you add the others?

ConfigProvider

When you install laminas-form, Composer should prompt you if you want to inject one or more ConfigProvider classes, including those from laminas-hydrator, laminas-inputfilter, and several others. Always answer "yes" to these; when you do, a Composer plugin will add entries for their ConfigProvider classes to your config/config.php file.

If for some reason you are not prompted, or chose "no" when answering the prompts, you can add them manually. Add the following entries in the array used to create your ConfigAggregator instance within config/config.php:

    \Laminas\Form\ConfigProvider::class,
    \Laminas\InputFilter\ConfigProvider::class,
    \Laminas\Filter\ConfigProvider::class,
    \Laminas\Validator\ConfigProvider::class,
    \Laminas\Hydrator\ConfigProvider::class,

If you installed Mezzio via the skeleton, the service Laminas\View\HelperPluginManager is registered for you, and represents the helper plugin manager injected into the PhpRenderer instance. This instance gets its helper configuration from the view_helpers top-level configuration key — which the laminas-form ConfigProvider helps to populate!

At this point, all view helpers provided by laminas-form are registered and ready to use.
