Passing infromation between regions / index blocks...

I am trying to figure out a way to structure (limit) my end-user's creativity whilst editing the website.

I am using a "Current Page" index block to gather all of the options the user can select/deselect using the Data Definition for the given page. That covers Region A. I am using a different index block in Region B for the navigation.

The problem I am running into is when it comes to passing information from one region to another. If Region A (Current Page Index Block) says: no navigation. How do I get Region B to adhere to that?

One way this could be done is allowing the user to select the navigation's index block in the Data Definition with a selector. Then all of the formatting could be done within the same index block.

Is this my only option?

   Hi Chris,

   You could accomplish this in one of two ways:

   • Include the calling page information with your navigation Index Block, so your navigation Format has access to both calling page data and the indexed content
   • Use a standalone Velocity Format and utilize the $currentPage variable, which will give you access to a Page API object for the calling page.

   Please let me know if you have any questions.

   Thanks!

   Awesome, thank you Mr. Griffith!

   Took me a little while to figure out where the $currentpage started looking through the XML, and then to get the values of a checkbox into an array, but I have it working great now!

   Reference Page Index Block Region A

   <system-data-structure definition-path="Default">
    <options>
     <value>Banner</value>
     <value>Sidebar</value>
    </options>
   </system-data-structure>
   

   Velocity Region B

   #set ($pageOptions = $currentPage.getStructuredDataNode("options").textValues)
   
   #if ($pageOptions.size() > 0 )
    #foreach ( $option in $pageOptions )
     ...
    #end
   #end
