Display an area or a random scrapbook block

Posted by Jeremy on April 4, 2011

I wrote this little snippet of php code today to either show an area to throw a banner image in, or grab from a scrapbook filled with banner images and display a random one.  It's a little more advanced than the block->getByName() functions that I usually use, I thought I'd share.  I know other people could probably use this code...

  1. <?php
  2.      $_blocks = $c->getBlocks("Banner");
  3.      if ((count($_blocks) > 0) || $c->isEditMode()) {
  4.           $a = new Area("Banner");
  5.           $a->setBlockLimit(1);
  6.           $a->display($c);
  7.      } else {
  8.           $scrapbookHelper = Loader::helper('concrete/scrapbook');
  9.           $scrapbookPage = $scrapbookHelper->getGlobalScrapbookPage();
  10. // area name is what the scrapbook is called, scrapbooks are really just areas when you get right down to it.
  11.           $scrapbookArea = new Area("Random Inside Banners");
  12.           $bannerBlocks = $scrapbookArea->getAreaBlocksArray($scrapbookPage);
  13.           $totalBlocks = count($bannerBlocks) - 1;
  14.           $i = rand(0, $totalBlocks);
  15.           $bannerBlock = $bannerBlocks[$i];
  16.           $bannerBlock->display();
  17.      }?>
