General question about validation in router

Question

I have a news-module.

It got a Router.php.

At the moment, I validate in there, if theres an entry in DB for the URL it wants to rout to. If yes -> got to my news_view.phtml -> if not -> 404

What I want to achieve is to transfer the already loaded collection to my view because I dont want to load it twice. Once for validation in Router and then to display Data in view.

I know bout parameters, but is it a good idea to transfer like 50 lines news-text over parameters?

May I miss something totally here :-/

May someone of you got completely different approach. I am open for everything! Thx in forward!

Answer 1

You can use the Mage::register for this, here you can store data and retreive it in some other place.

To register a variable use:

Mage::register('some_name', $var);

Then to retreive the value simply use:

$my_var = Mage::registry('some_name');

And if you want to unload the variable you can use:

Mage::unregister('some_name');

The values stored in the register are only available during the active request, when you reload your page the register is flushed.

Answer 2

First of all I don't know why you get 50 lines in the collection. You should get one or none.
Maybe you should have a different approch on the validation of the url. Add a limit of 1 to the collection.
But anyway...you can use Mage::register to remember the loaded data.

Mage::register('news_data', $newsData);

And in the news view page just check:

$newsData = Mage::registry('news_data');
if (!$newsData){
   $newsData = 'Load data again'
}

My way to find out what is wrong with my adminhtml module: I've added logging in

Mage_Core_Controller_Varien_Router_Standard::collectRoutes() (at the end)

mage::log("collectRoutes:". print_r($this->_modules,1),1,'router.log');

and also in Mage_Core_Controller_Varien_Router_Standard::getControllerFileName mage::log("Mage_Core_Controller_Varien_Router_Standard::getControllerFileName\n $file\n",1,'router.log');

and Mage_Core_Controller_Varien_Router_Standard::validateControllerFileName

 mage::log( "Mage_Core_Controller_Varien_Router_Standard::validateControllerFileName\n $fileName\not valid/not readable\n",1,'router.log');

from these logs I've found out what exactly the router is searching and fixed the issue
