Integration of Zend_View and Zend_Controller

Mainly in the Zend_Controller_Action class

/ * Initialize View object * * Initializes {@ link $view} if not otherwise a Zend_View_Interface. * * If {@ link $view} is not otherwise set, instantiates a new Zend_View * object, using the 'views' subdirectory at the same level as the * controller directory for the current module as the base directory. * It uses this to set the following: *-script path = views/scripts/ *-helper path = views/helpers/ *-filter path = views/filters/ * * @ return Zend_View_Interface * @ throws Zend_Controller_Exception if base view directory does not exist * / public function initView () {if (! $this- > getInvokeArg ('noViewRenderer') & & $this- > _ helper- > hasHelper (' viewRenderer')) {return $this- > view } require_once 'Zend/View/Interface.php'; if (isset ($this- > view) & & ($this- > view instanceof Zend_View_Interface)) {return $this- > view;} $request = $this- > getRequest (); $module = $request- > getModuleName (); $dirs = $this- > getFrontController ()-> getControllerDirectory (); if (empty ($module) |! isset ($dirs [$module])) {$module = $this- > getFrontController ()-> getDispatcher ()-> getDefaultModule () } $baseDir = dirname ($dirs [$module]). DIRECTORY_SEPARATOR. 'views'; if (! file_exists ($baseDir) | |! is_dir ($baseDir)) {require_once 'Zend/Controller/Exception.php'; throw new Zend_Controller_Exception (' Missing base view directory ("). $baseDir. '"));} require_once' Zend/View.php'; $this- > view = new Zend_View (array ('basePath' = > $baseDir)); return $this- > view;} / * * Render a view * * Renders a view. By default, views are found in the viewscript path as * / .phtml. You may change the script suffix by * resetting {@ link $viewSuffix}. You may omit the controller directory * prefix by specifying boolean true for $noController. * By default, the rendered contents are appended to the response. You may * specify the named body content segment to set by specifying a $name. * * @ see Zend_Controller_Response_Abstract::appendBody () * @ param string | null $action Defaults to action registered in request object * @ param string | null $name Response object named path segment to use; defaults to null * @ param bool $noController Defaults to false I.e. Use controller name as subdir in which to search for viewscript * @ return void * / public function render ($action = null, $name = null, $noController = false) {if (! $this- > getInvokeArg ('noViewRenderer') & & $this- > _ helper- > hasHelper (' viewRenderer')) {return $this- > _ helper- > viewRenderer- > render ($action, $name, $noController);} $view = $this- > initView (); $script = $this- > getViewScript ($action, $noController) $this- > getResponse ()-> appendBody ($view- > render ($script), $name);} / * * Render a given viewscript * * Similar to {@ link render ()}, this method renders a viewscript. Unlike render (), * however, it does not autodetermine the viewscript via {@ link getViewScript ()}, * but instead renders the script passed to it. Use this if you know the * exact viewscript name and path you wish to use, or if using paths that do not * conform to the spec defined with getViewScript (). * By default, the rendered contents are appended to the response. You may * specify the named body content segment to set by specifying a $name. * * @ param string $script * @ param string $name * @ return void * / public function renderScript ($script, $name = null) {if (! $this- > getInvokeArg ('noViewRenderer') & & $this- > _ helper- > hasHelper (' viewRenderer')) {return $this- > _ helper- > viewRenderer- > renderScript ($script, $name);} $view = $this- > initView (); $this- > getResponse ()-> appendBody ($view- > render ($script), $name);}
