Frog CMS

Hi all,

The Observer pattern is a good way to extend frog functionality with plugins. Thank you Philippe to have implemented it!

I just don't found a good list of all events that's can be observeable (this page is not totally up-to-date).

Here the actual (r162) list:

• view_page_edit_plugins
  Can be used to add custom field at the bottom of the page edit view
  Parameters:

  • $page: the Page model object

• view_page_edit_tabs
  Can be used to add a tab in the page edit view
  Parameters:

  • $page: the Page model object

• view_page_edit_popup
  ?
  No parameter.

• page_edit_before_save
  Can be used to perform special stuff before saving the page. No parameter.

• page_not_found
  When a page is not found
  No parameter.

• page_found
  just before displayed the page
  Parameters:

  • $page: the Page model object

I have some idea to improve this list:

First, it would be nice to have a reference to the page object in parameter when it is possible and when there are a sense (for example the page_edit_before_save event have no parameter).

It would be nice to have more observers too. Here some ideas:

• page_add_before_save (with a &$page params)
• page_delete (with an $id or $page params)
• part_edit_before_save (with a &$part param)
• page_requested (with a $url param) : I need an event like this in the frontend/main.php before trying to found a page. It would be useful to implement a cache plugin.

What do you think about that ?

Hi ricks,

Sure, it’s really easy :-) See this exemple:

// in your plugin index.php file
Observer::observe('page_edit_after_save', 'my_simple_observer');

// in the same file
function my_simple_observer($page)
{
    /* do want do you want */
   var_dump($page);
}

But perhaps, for your need, it’s better to use the ‘part_edit_after_save’ event:

Observer::observe('part_edit_after_save', 'my_simple_part_observer');

function my_simple_part_observer($part)
{
  if('body' == $part->name)
  {
     /* do something with the body content ($part->content or $part->content_html) */
     var_dump($part);
  }
}
