Integrating Zend Form in Zend Expressive and Zend View

Fri, 13 Nov 2015 00:00:00 +0000

Example is based using Aura.Di. But the functionality will be same for any containers. First register the service Zend\View\HelperPluginManager, so that we can access the same object.

To register the form helpers, create the object of Zend\Form\View\HelperConfig and pass the Zend\View\HelperPluginManager service.

Example code with Aura.Di version 3 configuration.

<?php
use Aura\Di\ContainerConfig;
use Aura\Di\Container;
use Zend\Form\View\HelperConfig;

class ViewHelper extends ContainerConfig
{
    public function define(Container $di)
    {
        $di->set('Zend\View\HelperPluginManager', $di->lazyNew('Zend\View\HelperPluginManager'));
    }

    public function modify(Container $di)
    {
        $serviceManager = $di->get('Zend\View\HelperPluginManager');
        $helper = new HelperConfig();
        $helper->configureServiceManager($servicemanager);
    }
}

Creating your own zend-view helper
#

Create your helper class

<?php
namespace App\View\Helper;

use Zend\View\Helper\AbstractHelper;

class HasError extends AbstractHelper
{
    // add as many parameters you want to pass from the view
    public function __invoke()
    {
        // some code
    }
}

Registering your helper class.

First get the Zend\View\HelperPluginManager service.

Speed Up Configuration in Aura v2

Sat, 06 Dec 2014 00:00:00 +0000

Aura v2 added auto resolution in-order to help lazy people writing configuration manually. Even though it was introduced to help, it introduced a few issues.

So auto resolution will be disabled in the future. Some of the complains/suggestions are how to easily write the di configuration.

So introducing you FOA.DiConfig
