0. You already have access to the content's properties. $this->content->getUsername(); $this->content->isSection(); etc. Look at the public functions of vBCms_Item_Content & vBCms_Item_Content_Article for the methods you can call.

You really don't need to directly query the database again for on-page content.

1. Caching is done in vBCms_Widget_ExecPhp::getPageView() between lines 174 & 175. For testing, I added the NodeId to the hash to make the cache unique to the current node...you can just comment out the reading of the cache on 175 if you want to.

This was my code in line 174 for testing:

PHP Code:

$hash = $this->getHash($this->widget->getId() . _ . $this->content->getNodeId()); 


But, no hooks. You have to modify the code.

2. Again, you'll have to directly modify the widget's code. Around line 173, add the following line:

PHP Code:

$view->issection = $this->content->IsSection()?1:0; 


Then your conditional should work.

My sample widget code:

PHP Code:

$output = 'Username: ' . $this->content->getUsername() . '<br/>';
$output.='Content Type Id: ' .  $this->content->getContentTypeId() . '<br />';
$output.= 'Is Section: ' .  $this->content->IsSection() . '<br />'; 


My edited widget class code:

PHP Code:

$view = new vBCms_View_Widget($config['template_name']);
        $view->class = $this->widget->getClass();
        $view->title = $view->widget_title = $this->widget->getTitle();
        $view->description = $this->widget->getDescription();
        $view->issection = $this->content->IsSection()?1:0;

        $hash = $this->getHash($this->widget->getId() . _ . $this->content->getNodeId());
        $view->output = vB_Cache::instance()->read($hash, true, true); 


Edit: In lieu of editing core code, you could also subclass the PHP widget and implement a new getPageView method. You'd have to install a new version of the widget...but it would make your changes less global.
