[zf2 beta5] How to perform operations on generated HTML?

[Jonathan Maron]

Hello all

I have a number of components, which perform operations on all of the
generated HTML.

For example, one component writes the "generated at" date as a comment
to the end of the HTML page. Another one rewrites all <img /> src
attributes to point to a CDN etc.

Previous to zf2 beta5, I achieved this as follows:

namespace Application

class Module [..]

public function init(ModuleManager $moduleManager)
{
    $sharedManager = $moduleManager->events()->getSharedManager();

    $sharedManager->attach('Zend\Mvc\Application', 'finish',
            array('My\X\GeneratedAt', 'execute'), 2);

    $sharedManager->attach('Zend\Mvc\Application', 'finish',
            array('My\X\Cdn',         'execute'), 3);
}

Where My\X\GeneratedAt and My\X\Cdn perform their operations on the HTML.

How can I achieve the same functionality in ZF2 beta5?

TIA

Jonathan

Hi Jonathan,

that should quite work,  try it with the alias 'application'  instead of 'Zend\Mvc\Application'

Hello Hasan

Thanks for your assistance. It turns out, the solution is as follows.
How this helps someone:

public function onBootstrap(\Zend\Mvc\MvcEvent $e)
{
    $sharedManager =
$e->getApplication()->getEventManager()->getSharedManager();

    $sharedManager->attach('Zend\Mvc\Application', 'finish',
            array('My\X\GeneratedAt', 'execute'), 2);

    $sharedManager->attach('Zend\Mvc\Application', 'finish',
            array('My\X\Cdn',         'execute'), 3);

}

Hi Jonathan,

my fault,  your first one will also work with

getEventManager()  

instead of

events()

I've overseen that.  But onBootstrap is ok in this case

By the way, there's actually no reason to use the shared event manager
in this instance. Since you're grabbing the EM from the application
instance already, just register directly with it.

    public function onBootstrap(\Zend\Mvc\MvcEvent $e)
    {
        $events = $e->getApplication()->getEventManager();
        $events->attach('finish', array('My\X\GeneratedAt', 'execute'), 2);
        $events->attach('finish', array('My\X\Cdn',         'execute'), 3);
    }

Thank you Matthew for the suggestion. This does, indeed, make more sense.
