PHP Question

R_J

I was thinking about creating a little plugin that makes navigating through the long list of plugins easier by providing an alphabetical shortcut list. This is what I started with:

class PluginNavigatorPlugin extends Gdn_Plugin {
   public function SettingsController_BeforeRenderAsset_Handler($Sender) {
      // stop if not Content of Plugins section
      if (($Sender->EventArguments['AssetName'] != 'Content') || (substr($Sender->SelfUrl,0, 16) != 'settings/plugins')) {
         return;
      }
      $Content = $Sender->Assets['Content'];
      // some regex magic here
      $ContentNew = preg_replace('/(< div class="Info">)/', '$1Index: A B C D E F...< /div>$1', $Content);
      $Sender->Assets['Content'] = $ContentNew;
   }
}

Looks clean and easy but does not do anything

If I look at where the event is fired, I see this (class.controller.php):

public function RenderAsset($AssetName) {
   $Asset = $this->GetAsset($AssetName);

   $this->EventArguments['AssetName'] = $AssetName;
   $this->FireEvent('BeforeRenderAsset');

   //$LengthBefore = ob_get_length();

   if(is_string($Asset)) {
      echo $Asset;
...

So I would have to change the var $Asset in the scope of the function RenderAsset. Is this possible?

No.

There are other approaches to do what you want to do, but as far as I know, there is no way to access variables out of scope.

EDIT: Clever regex, btw.

the dreaded reflection methods.

Yes, I've thought about js and later on I remembered I could simply create a custom view. I think I simply create such a view. Thanks for answering even simple php questions
