Social icons in Pagelist template

Permalink
I am building out a blog with 5.7 and have the Social "Share" block in my Post template. I need to pass that to the pagelist template I created for the blogroll on the homepage.

I found how to pass the "Content" block over instead of the description. But it's set to truncate at 200 characters.

How can I pass the Share Page block to my Pagelist view?

I thought I could do it like the content block but it's throwing an error.

<?php 
                        $pBlocks = $page->GetBlocks();
                          foreach ($pBlocks as $pBlock){
                                if ($pBlock->btHandle == 'content') {
                                    $blockContent = $pBlock->getInstance();
                                    $description = $blockContent->getContent();
                                    $description = substr($description,0, 200);
                                    echo $description;
                                    echo '...';
                                }
                          }
                        ?>
