Hooks to edit controller function - El Forum - 06-14-2012

Hi there,

Well, I'm try to create a plugin system based on hooks, but I'm so confused in how hooks could alter a specific controller function, look the example below:

Code:
class Article extends CI_Controller

{

 public function index()

 {

  $title = $this->input->post('title');

  $body = $this->input->post('body');

  //try to add a new line here using hooks

  //maybe to add a new property like:

  //$published = $this->input->post('date') 

 }

}

How can I add a new line after where I have a commented line? I have tried with hooks but not good results. Additionally, I thought that using hooks is the best way to create a plugin system without changing the core code.

Thanks in advance

OK, I found the answer (at least one option).You need to set "hooks point" as many you need, in my case I did it by this way:

Code:
class Article extends CI_Controller

{

 public function index()

 {

  $title = $this->input->post('title');

  $body = $this->input->post('body');

  $article = new Article();

  $article->setTitle($title);

  $article->setBody($body);

  do_action('before_persist', $article);

  $this->my_db->save($article);

 }

}

Finally, my "before_persist" function have the correct code in order to add new properties to $article object

Code:
$register_hook('before_persist', 'add_date_article', $params);

Code:
function add_date_article($params)

{

   $article = $params[0];

   $published = $this->input->post('date');

   $article->setPublished($publiched);

}
