Default Smarty Implementation
Frist of all I am a newbie to zf. I have been out of the programming scene for a while.

I came across zf and decided to take a look at it.After reading the manual and some other sites I started playing around with it.

I guess first things first my directory structure
Code:
/application
    /config  --holds zf config file
    /controllers
    /models
    /Smarty  -- Smarty specific folders
         /cache
         /config
         /templates
         /templates_c
    /views
         /index
         /user
/library
    /Smarty  --  holds all smarty files
    /Zend  --  holds all zf files
.htaccess
index.php  --  bootstrapper file
I am using the zend veiw smarty layout that is in the manual. Zend Framework: Documentation

made a few adjustments to the Smarty.php script
PHP Code:
<?php
require_once 'Zend/View/Interface.php';
require_once 'Smarty/Smarty.class.php';

class Zend_View_Smarty implements Zend_View_Interface
{
    /**
     * Smarty object
     * @var Smarty
     */
    protected $_smarty;
    /**

    public function __construct($tmplPath = null, $extraParams = array())
    {
        $this->_smarty = new Smarty;
        if (null !== $tmplPath)
        {
            $this->setScriptPath($tmplPath);

My Bootstrapper looks like so:
PHP Code:
<?PHP

/*
*Error Reporting
*/
error_reporting(E_ALL|E_STRICT);
ini_set('display_errors', 'On');
set_include_path(dirname(__FILE__) . '/library' . PATH_SEPARATOR . get_include_path());

/*
* Zend Loader
* Loads all the Zend classes the script uses
*/
require'Zend/loader.php';
/*
* Required Classes
* Class we need are accesssed through namespaces instead of direct files
* example Zend_Controller_Front will load /Zend/Controller/Front.php
*/
Zend_Loader::loadclass('Zend_Controller_Front');
Zend_Loader::loadclass('Zend_Config_Ini');
Zend_Loader::loadclass('Zend_Registry');
Zend_Loader::loadclass('Zend_Db');
Zend_Loader::loadclass('Zend_View_Smarty');

/*
* Load the config file
*/
$config = new Zend_Config_Ini('application/config/Config.ini', 'general');

/*
* Connect to database
*/
$db = Zend_Db::factory($config->db);

/*
* Setup the controller
*/
$front = Zend_Controller_Front::getInstance();
$front->setControllerDirectory('application/controllers');
$front->throwExceptions(true);

/*
* Run the page and display it  GO!!!
*/
$front->dispatch();
I saved the Smarty.php to Zend/View so I can load it using the Zend_Loader

My IndexController.php looks like
PHP Code:
<?PHP

class IndexController extends Zend_Controller_Action {

    function indexAction()
    {
        //Logic Code goes here


        $view = new Zend_View_Smarty();
        $view->setScriptPath('application/Smarty');
        $view->books = 'Zend PHP 5 Certification Study Guide';
        $view->author = 'Davey Shafik and Ben Ramsey';
        $rendered = $view->render('bookinfo.tpl');


    }
}
What happens is everything works now to an extent but the .tpl files arenot outputing. I know I am overlooking something simple if someone could help me I would appreciate it.

If you need any more info just drop me a line.

Hello,

Perhaps you can try to expend Zend_View

Code:
class Zend_View_Smarty expends Zend_View implement...

Thanks for this, I spent the whole day trying to get Smarty working with Zend. I just followed your directory structure and got it working.
You may have already figured out, but all I did to get it to render is to echo out what is rendered.

PHP Code:
$rendered = $view->render('bookinfo.tpl'); 
echo $rendered;

Default New changes and addons
I have updated the code to fix a few problems and make the view default to the Smarty Directory structure
Code:
/application
    /config  --holds zf config file
    /controllers -- Holds the Controllers needed for the script
          IndexController.php
          UserController.php
          AdminController.php
    /models
    /Smarty  -- Smarty specific folders
         /cache
         /config
         /templates  -- templates for the site are stored here
         /templates_c --smarty cached directory
    /modules
         Whatever modules you want for the script
/images
/js
/library
    /Smarty  --  holds all smarty files
    /Zend  --  holds all zf files
.htaccess
index.php  --  bootstrapper file

Bootstrapper is like so:

$front->throwExceptions(true);
$front->setParam('useDefaultControllerAlways', true);

/*
* Run the page and display it  GO!!!
*/
$front->dispatch();
The controller files have this basic set up
PHP Code:
class IndexController extends Zend_Controller_Action {

    public function init()
    {
        // Set Smarty defaults so it is availale throught the class
        $this->view = new Zend_View_Smarty();
        $this->view->setScriptPath('application/Smarty');
        $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer($this->view);
        $viewRenderer->setViewBasePathSpec('application/Smarty/templates');
        $viewRenderer->setViewScriptPathSpec(':module/:controller/:action.:suffix');
        $viewRenderer->setViewScriptPathNoControllerSpec(':action.:suffix');
        $viewRenderer->setViewSuffix('tpl');
        Zend_Controller_Action_HelperBroker::addHelper($viewRenderer);
        require 'application/config/site_setting.php';
        $settings = $configarray;
        $this->view->assign('set', $settings);

    }

    public function indexAction()
    {
        //Logic Code goes here
        $results = array(
        'author' => 'Davey Shafik and Ben Ramsey',
        'title' => 'Zend PHP 5 Certification Study Guide'
        );


        $this->view->assign('results', $results);
        $this->view->display('book_view.tpl');
    }
} 
Routes file sample: We use this for a sort referrer url that defaults to admin if the user is not found and redirects to the main page automatically which was really neat
PHP Code:
[routes]
routes.r.type = "Zend_Controller_Router_Route"
routes.r.route = "r/:username"
routes.r.defaults.controller = user
routes.r.defaults.action = setreferrer
routes.r.default.username = admin

Changes are simple but made a lot more flexiblity in the script and in what we where trying to accomplish the use of the routes helped make the url short and sweet and search engine friendly.

It also Bypasses the views directory and goes straight to the smarty directory where all templates are stored. So we don't need to echo the rendered object it is displayed automatically when everything is done right.

I hope this helps anyone that likes the flexibility of smarty if you find a better way of doing this and want to share drop me a line.
