Class

LayoutRendererStandard

The standard render for a Layout display object.

Code

function renderBlocks() {
  $this->rendered['blocks'] = array();

  // Do a pass through all blocks to check for the main system content block.
  // This serves a dual-purpose of rendering the system block first, allowing
  // modifications to other blocks (such as breadcrumb), and it prevents
  // rendering of all other blocks in the event of a 404 or 403 response from
  // the system menu handler.
  foreach ($this->prepared['blocks'] as $uuid => $block) {
    if ($block->module === 'system' && $block->delta === 'main') {

      // If a 404 or 403 skip all rendering and return nothing, as the error
      // page will generate its own replacement content.
      if ($response_code === MENU_NOT_FOUND || $response_code === MENU_ACCESS_DENIED) {
        $this->menu_response = $response_code;
