Get Named Blocks Content from Page Composer

Permalink
Hi!

I created a custom PageType (News Entry) from scratch where I added fields for the composer with named entities (e.g. "News Content").
After that I could successfully create standard output using a Composer-Block.

But now I want to be able to get the content of "News Content" programmatically for a given Page.

I can use

$page->getBlocks()


to get all Blocks on a page.
Using some code I found in the Composer Block I also can identify Composer controls with Custum Labels:

$pt = PageTemplate::getByID($page->getPageTemplateID());
$ptt = PageType::getByID($page->getPageTypeID());
$controls = PageTypeComposerOutputControl::getList($ptt, $pt);
foreach($controls as $control) {
   $fls = PageTypeComposerFormLayoutSetControl::getByID($control->getPageTypeComposerFormLayoutSetControlID());
   if($fls->getPageTypeComposerFormLayoutSetControlCustomLabel()) {
      echo $fls->getPageTypeComposerFormLayoutSetControlCustomLabel();
   }      
}


But how can I merge this information to get the content for the control labeled "News Content"?

Thanks for your help!

Or, to keep it simple, I want to get the value of e.g. "News Teaser" as shown in the composer (see attachment) programmatically for a given page object.

How can I achieve this?

I believe I know what you are asking.

An example, let's say the text area attribute called News Teaser has the handle "news_teaser".

One way to access that attribute value is with getCollectionAttributeValue().
Example:
$c->getCollectionAttributeValue('news_teaser')

Unfortunatly its not that simple...

...this is not an attribute, but a block from composer. As I understand the content is copied to a standard block when a page is published.

I found the class handling to get the block when the control is known (\Concrete\Core\Page\Type\Composer\Control\BlockControl), but the relevant function ( getPageTypeComposerControlBlockObject(Page $c)) is protected.

Is there any way to extend this class?

OK... as I could not figure out how to extend the BlockControl class, I managed to succeed using reflection to call the protected method:



// assuming $page contains a valid page object
// get page template and type
$pt = PageTemplate::getByID($page->getPageTemplateID());
$ptt = PageType::getByID($page->getPageTypeID());
// get all contrrols
$controls = PageTypeComposerOutputControl::getList($ptt, $pt);
foreach($controls as $control) 
{
   $fls = PageTypeComposerFormLayoutSetControl::getByID($control->getPageTypeComposerFormLayoutSetControlID());
    // check if control has custom label
   if($fls->getPageTypeComposerFormLayoutSetControlCustomLabel() == "News Content") { 
      $bc = $fls->getPageTypeComposerControlObject();
        $bc->setPageTypeComposerFormLayoutSetControlObject($fls);
        // invoke protected function using reflection...
        $r = new ReflectionMethod('Concrete\Core\Page\Type\Composer\Control\BlockControl', 'getPageTypeComposerControlBlockObject');

Maybe there is a more elegant way, but for the moment it works.
