Here I am going to show how one can create breadcrumbs in the web application based on Zend Framework. This can be achieved by creating a helper method. Before creating helper method, we need to do the following exercise:
- Create Zend view object,
- Add view script path,
- Add the default helper path to the view object,
Now lets start step by step:
Creating Zend view object:
$view = Zend_View();
Adding view script path:
$viewPath = “path/to/viewsDirectory”;
$view->addScriptPath($viewPath);
Adding the default helper path to the vew object:
$helperPath = “path/to/helperDirectory”; Zend_Controller_Action_HelperBroker::getStaticHelper(‘viewRenderer’)->setView($view);
$view->addHelperPath($helperPath, ‘Helper_’);
Now creating the class for the breadcrumbs:
class Helper_BreadCrumbs {
public function breadCrumb(){
$cFront = Zend_Controller_Front::getInstance();
$module = $cFront->getRequest()->getModuleName();
$module = strtolower($module);$controller = $cFront->getRequest()->getControllerName();
$controller = strtolower($controller);$action = $cFront->getRequest()->getActionName();
$action = strtolower($action);if($module == “default” && $controller == “index” && $action == “index”){
return;
}
//Home link
$home = ‘<a href=”/”>Home</a>’;//start breadcrumbs
$bCrumbs = $home . “::”;
if($action == “index”){
$bCrumbs .= $controller;
}
else{
$bCrumbs .= “<a href=’/$controller’>$controller</a>::
<a href=’/$controller/$action’>$action</a>”;
}return $bCrumbs;
}
}
Hope this article will help the web application users to indicate “where are you”.
