[fw-general] layout placeholders

[vadim gavrilov]

I have the following structure:

class BaseMasterController extends Zend_Controller_Action
{
    public $view;
    public $breadcrumbs = array();

    public function init()
    {
        # Define module path
        defined('MODULE_PATH')
        or define('MODULE_PATH',
Zend_Controller_Front::getInstance()->getModuleDirectory() . '/');

        # Define controller path
        defined('CON_PATH')
        or define('CON_PATH',
Zend_Controller_Front::getInstance()->getModuleDirectory() . '/');

        # Set layout and views directories
        Zend_Layout::startMvc( MODULE_PATH .'/layouts/scripts' );

        # Init views object
        $this->view = Zend_Layout::getMvcInstance()->getView();
        $this->view->doctype( Zend_Registry::get('config')->layout->doctype
);
        $this->view->setScriptPath( MODULE_PATH . 'views/scripts/' );
        $this->viewRenderer = $this->_helper->getHelper('viewRenderer');
        $this->viewRenderer->setView($this->view)->setViewBasePathSpec(
MODULE_PATH . 'views/scripts/'
)->setViewScriptPathSpec(':controller/:action.phtml');

        # Build Helpers
        $this->view->addHelperPath( MODULE_PATH . 'views/helpers/',
'Helper');

        # setting content type and character set

$this->view->headMeta()->appendHttpEquiv('X-UA-Compatible','IE=EmulateIE7')->appendHttpEquiv('Content-Type','text/html;
charset=UTF-8')->appendHttpEquiv('Content-Language', 'en-US');

        # setting a separator string for segments:
        $this->view->headTitle()->setSeparator(' :: ');

        # Load the DB Adapter
        $this->db =
Zend_Db::factory(Zend_Registry::get('config')->production->database);

        # Clean Globals
        $this->input = new Input;
     }
}

class BaseEndController extends BaseMasterController
{
    public function init()
    {
        # Set Up view properties
                $this->view->breadcrumbs = array();

              # Create the base breadcrumb
                $this->view->breadcrumbs[] = $this->BB(
$this->lang->_('GL1'), array('index', 'index', 'admin'));
    }
}

class Admin_IndexController extends BaseEndController
{

    public function indexAction()
    {
        $this->view->breadcrumbs[] = "123";
        $this->viewRenderer->render('index');
    }
}

then in the layout i am doing:

<?php if( $this->breadcrumbs ): ?>
            <ul class="breadcrumbs">
                <?php foreach($this->breadcrumbs as $crumb): ?>
                <li><?php echo $crumb; ?></li>
                <?php endforeach; ?>
            </ul>
        <?php endif; ?>

but for some reason the $this->breadcrumbs array has only one element which
was added in the BaseEndController class. the element that was added in the
indexcontroller class was not actually added to the array and is not shown
when it prints it.

Any idea why, Or how to solve it? any other approach for something similar?

Thanks.
