Hey guys.
I really need help here. I've looked everywhere, but I can't find anything I understand. And I never use code I don't understand: I'm pretty new to PHP.
I'm building a blog/cms system and I need a way to easily allow the use of plugins.
The plugins should have access to the $this-> object of the current class. It should also work a little like hooks like this:
<?php
// do stuff
$plugins->execute("before_render");
// do stuff
//render
?>
The plugins class should load all the plugins (in the beginning of the app) and then execute the ones that are labeled to be executed in the hook point "before_render."
Now, imagine I have something like this, in a class:
<?php
// do stuff
$this->content = "test";
$plugins->execute("before_render");
echo $this->content;
?>
And in the plugin, it says something like:
<?php
$this->content = "asdfsadf";
?>
So that when the page loads, $this->Content has been changed by the plugin!
I've already made a hooks system, and it works quite well. However it has no ability to access the parent class. I saw something somewhere which uses "implements Plugins" or something like, but I don't understand that.
Basically what I'm asking for is a really short and clean example of how I would do all this.
I found an example of what I mean: http://www.w3style.co.uk/?p=9. That code looks really complex and unnecessary, can someone help explain it better or help me write this cleaner?
Thanks so much!
