copied!<p>I'm working through <a href="http://rads.stackoverflow.com/amzn/click/1590599063" rel="nofollow noreferrer">Practical Web 2.0 Appications</a> currently and have hit a bit of a roadblock. I'm trying to get PHP, MySQL, Apache, Smarty and the Zend Framework all working correctly so I can begin to build the application. I have gotten the bootstrap file for Zend working, shown here:</p> <pre><code><?php require_once('Zend/Loader.php'); Zend_Loader::registerAutoload(); // load the application configuration $config = new Zend_Config_Ini('../settings.ini', 'development'); Zend_Registry::set('config', $config); // create the application logger $logger = new Zend_Log(new Zend_Log_Writer_Stream($config->logging->file)); Zend_Registry::set('logger', $logger); // connect to the database $params = array('host' => $config->database->hostname, 'username' => $config->database->username, 'password' => $config->database->password, 'dbname' => $config->database->database); $db = Zend_Db::factory($config->database->type, $params); Zend_Registry::set('db', $db); // handle the user request $controller = Zend_Controller_Front::getInstance(); $controller->setControllerDirectory($config->paths->base . '/include/Controllers'); // setup the view renderer $vr = new Zend_Controller_Action_Helper_ViewRenderer(); $vr->setView(new Templater()); $vr->setViewSuffix('tpl'); Zend_Controller_Action_HelperBroker::addHelper($vr); $controller->dispatch(); ?> </code></pre> <p>This calls the IndexController. The error comes with the use of this Templater.php to implement Smarty with Zend:</p> <pre><code><?php class Templater extends Zend_View_Abstract { protected $_path; protected $_engine; public function __construct() { $config = Zend_Registry::get('config'); require_once('Smarty/Smarty.class.php'); $this->_engine = new Smarty(); $this->_engine->template_dir = $config->paths->templates; $this->_engine->compile_dir = sprintf('%s/tmp/templates_c', $config->paths->data); $this->_engine->plugins_dir = array($config->paths->base . '/include/Templater/plugins', 'plugins'); } public function getEngine() { return $this->_engine; } public function __set($key, $val) { $this->_engine->assign($key, $val); } public function __get($key) { return $this->_engine->get_template_vars($key); } public function __isset($key) { return $this->_engine->get_template_vars($key) !== null; } public function __unset($key) { $this->_engine->clear_assign($key); } public function assign($spec, $value = null) { if (is_array($spec)) { $this->_engine->assign($spec); return; } $this->_engine->assign($spec, $value); } public function clearVars() { $this->_engine->clear_all_assign(); } public function render($name) { return $this->_engine->fetch(strtolower($name)); } public function _run() { } } ?> </code></pre> <p>The error I am getting when I load the page is this:</p> <p><code>Fatal error: Call to a member function fetch() on a non-object in /var/www/phpweb20/include/Templater.php on line 60</code></p> <p>I understand it doesn't see $name as an object, but I don't know how to go about fixing this. Isn't the controller supposed to refer to the index.tpl? I haven't been able to discover what the $name variable represents and how to fix this to get the foundation working.</p> <p>Any help you have is much appreciated!</p>
