[RELEASED] Override Engine for OpenCart

Post by dfumagalli » Wed Aug 28, 2013 10:15 pm

I'd have a suggestion.

It'd be nice to have:

1) An easy to call, official "IsOverrideEngineInstalled()" function to quickly detect if your framework is installed. Modders would use that call to display a "OE not detected please install from <link>" or even perform an automated installation (like qQModerator does for vQMod).

2) A sort of "Installation success checker" php file. Basically a guy would install your framework and then enter an URL and would see something like:

- Checking if I can instantiate a class from the factory
- Checking for blah blah (basic sanity checks)

"OE succesfully installed"

3) A commented "Hello world" mod skeleton (maybe optional download) to help OE modders get started. After all vQMod comes with examples and the Hostjars website provides an OC module builder and even an OC module creator.

4) A badge, that is an icon that modders can put in their admin section or wherever (maybe embed the code to instantiate it directly in the framework) that says: "Powered by OE framework".
Nothing fancy, just something like the W3C badge you can get if your site validates:

I have just found a little issue.

OE has born to let extend OC easier.
However I did not find an easy way to extend OE itself.

Use case:

- I created a memcached cache manager for OC.
- I need to instantiate and use it in place of the default cache class.

In original OC, I'd open index.php and would replace:

$cache = new cache();

with

$cache = new mycache();

With OE I have to go dig what

$cache = $factory->newCache();

does.

In system/engine/factory.php I find:

public function newCache() {
return $this->newSystemClass( 'library/cache.php' );
}

Now, in an ideal OOP world I'd expect:

1) public function newCache( $cacheImpl = 'library/cache.php' ) {
return $this->newSystemClass( $cacheImpl );
}

where I can customize the php file I include. This is really easy to implement in the OE core *hint*

2) Ability to inherit

class Factory {
}

and override the newCache() method with my own.

But no, Factory declaration starts with

final class Factory
{

so I can't inherit from it.

What shall I do? A vQMod of factory.php? Sounds quite weird to have to hack in with vQMod into the core of the Engine born to avoid using vQMod.

<?php  
class mycache_Cache extends Cache {

	// overridden method
	public function get($key) {
		// do my own stuff
		// ........
		return parent::get($key);
	}

	// overriden method
	public function set($key, $value) {
		// do my own stuff
		// ........
		parent::set($key,$value);
	}
	..........
}
?>
