Edited on 2007-05-17 05:21:51 by NilsLindenberg [note on files]
Additions:
Let's start with the show handler... (**handler/page/show.php**)
Now it's time to replace the Action() method in **root/wikka.php**:
We'll do the same for the Run() method in the same file (**root/wikka.php**):
Now we need to open up **wikka.config.php** and add the following lines to the bottom of the file:
Speaking of writing a new config file, maybe we should go ahead and do that. Save the following code as **uploads/action.config.php**:
Save the following in the wikka root directory as "**util.php**"...
Save the following in the actions directory as **installer.php**:

Additions:
Now create a page like "ActionInstaller" and call the action from within it like so -- ""{{installer}}"".
Deletions:
Now create a page like "ActionInstaller," restrict read/write access to an admin user, and call the action from within it like so -- ""{{installer}}"".

Revision [10600]

Edited on 2005-08-10 13:44:51 by DennyShimkoski [Added question about handlers]
Additions:
As you can see, the entire file has changed. Instead of directly printing everything to output, we're collecting it in a variable called $page. Also, we've moved the calls to Header() and Footer() out of the Run() method in wikka.php and put them at the bottom of this file. This will allow for actions to send headers to the browser directly, rather than requiring developers to define a separate "handler" file for such cases (**please discuss: was this ever actually a requirement?**). With this setup, actions will now be processed before anything is sent back to the browser.

Additions:
Here we look through the current page for any calls to actions that are installed on the system (through the InstallableActions interface). If we find any that included a CSS file as part of their installation package, we add the corresponding CSS file to an array.

Additions:
A special case for the show handler has been added -- the elseif ""($this->method == 'show')"" part. That's the only change.
return preg_match("/%REMOVE ME%\($language\)(.*)%REMOVE ME%/ismU", $wikka_body, $matches) ? $matches[1] : false;
**Note:** You'll have to find %REMOVE ME% and replace with ""%%"" in your text editor before the above code will work.
