Programatically editing a content block within a page

Permalink 2 users found helpful
Hi, All --

Given a page that I had just created from a page type, I was trying to find a (content) block and edit it with the "starter" text.

I spent a few hours trying to figure this out last night, and (surprisingly) couldn't find any help on the forums. Thought I'd document it here.

I was having tons of problems with the fact that the block is set up as an "alias" (to the "default" block held on the page type) and trying to de-alias the block. Then I realized I was running into caching issues, which made finding the solution harder (I assumed you get the block's controller instance in order to ->save(), but don't!).

Without further adieu:

$nb = $this->contentBlockObj->duplicate($this->pageObj); //pageObj is the same page the existing block is on... you can probably get it from the Block, but I had it stored for other reasons
$nb->update(array('content' => $this->descr));
$this->contentBlockObj = $nb;

James, I tried to implement your solution, but keep running into "the wall of unknown." :) Here's my code:

$blocks = $newPage->getBlocks('Sidebar');
foreach ($blocks as $b){
   $bID = $b->getBlockID();
   Log::addEntry('Group '.$group_name.' block id is '.$bID. ' and block handle is '.$b->getBlockTypeHandle().' and block type ID is '.$b->getBlockTypeID().' and block type name is '.$b->getBlockTypeName());
   $nb = $b->duplicate($newPage);
   $nb->update(array('frontend_access' => 'group', 'access_groupID' => $gID, 'fsID' => $fsID_bg ));
   $b = $nb;

$bID in the log shows 944, which refers to the page I created for test purposes a while ago. The most recent id in the DB is 1080, and I expected to log a block ID that followed 1080, not preceded it.

Is the newly created page pointing to the page type default's block ID? If so, how do I get the current instance of the block on the newly created page and update it?

Lots of thanks in advance for any help! I'm stuck...

To be honest, I don't really remember. It was one of those solutions that wasn't at all logical to me and required a lot of trial and error, and thus the solution didn't "click".

I think getting a bID of 944 is correct. That's the whole point of doing the ->duplicate() -- even a brand new page starts with a reference to the old blog that's part of the template. There is no "current instance".

But then I see that you' do the $b->duplicate() as I had done, and $b->delete(). So, basically, everything looks correct. Now, if you logged "block id is " . $nb->getBlockID(), you should have the new one.

Basically, what exactly is wrong, other than getting a confusing block id? Is your page not updating? Is the database not getting a new block?
