magento - Add block to all CMS Pages with certain URL Key -

i'm trying discover whether possible or not. have series of cms pages represent our library.

so url keys these pages like:

• library/
• library/top-ten
• library/five-questions
• library/faq
• etc...

the powers want add static block appear only on library cms pages. there way, in layout xml file, target pages contain keyword, along lines of

<default>     .... </default> <library_*>     <reference name="right">         <block goes here/>     </reference> </library_*> 

you may find this question useful understand cms page layouts. while can’t accomplish trying in way going exactly, here couple of options consider:

add layout xml each of cms pages in admin

this preferred solution since leverages out of box functionality, requiring less maintenance , no coding knowledge modify.

when editing cms page, go design tab:

here can change page template. select custom page template—that create static block inserted in right column—under layout, or add custom layout xml directly textfield:

admittedly, violate dry principle since on each relevant cms page, it’s not of violation , uses magento’s intended features.

create custom layout handle

similar example in question linked earlier, create simple extension adds new layout handles relevant cms pages. observer this:

class my_layouthandle_model_observer {     public function addlibrarycmshandle(varien_event_observer $observer)     {         if ($observer->getaction()->getfullactionname() == 'cms_page_view') {             $page = mage::getsingleton('cms/page');             if (substr($page->getidentifier(), 0, 7) == 'library') {                 /** @var $layout mage_core_model_layout */                 $layout = $observer->getlayout();                 $layout->getupdate()->addhandle('custom_handle_library_page');             }         }     } } 

then target new handle this:

<custom_handle_library_page>     <reference name="right">         <block goes here/>     </reference> </custom_handle_library_page>
