Magento - 如何在观察者中为块设置不同的phtml？

Question

Here is what I'm trying to do: I need to add a tab on category edit page on the backend (admin panel).

I add it from an Observer file this way:

$tabs = $observer->getEvent()->getTabs();
$tabs->addTab('features', array(
              'label'     => Mage::helper('catalog')->__('Related Pages'),
              'content'   => '',
));

The problem is that I do not know how to properly populate the 'content' attribute so I was thinking of getting the "Content" block and manually assigning to it a different phtml file.

Can it be done?

Thanks in advance.

Try this.

$tabs->addTab('features', array(
              'label'     => Mage::helper('catalog')->__('Related Pages'),
              'content'   => Mage::app()->getLayout()->createBlock('[module]/[block]')->setTemplate('path/to/template.phtml')->toHtml(),
));

So you need to create you own block that will be rendered by the path/to/template.phtml template.
If you don't need any logic in your template you can skip the creation of the block and use adminhtml/template . Something like this.

$tabs->addTab('features', array(
              'label'     => Mage::helper('catalog')->__('Related Pages'),
              'content'   => Mage::app()->getLayout()->createBlock('adminhtml/template')->setTemplate('path/to/template.phtml')->toHtml(),
));
