Question

我是zend框架的新手。我在模型文件夹中创建了Users.php。模型文件夹的代码如下。

<?php
include("Zend/Db/Table/Abstract.php");
include("Zend/Db/Table/Row/Abstract.php");
    class users extends Zend_Db_Table_Abstract {
        protected $_name = 'users';
        protected $_rowClass = 'Application_Model_DbTable_User';

        public function fetchUsers() {
            $select = $this->select();
            //$select->where('completed = 0');
            $select->order(array('date_created DESC', 'user_id ASC'));
            return $this->fetchAll($select);
        }
        public function insert_user1(array $data) {
            echo "called";
        }
    }

    class Application_Model_DbTable_User extends Zend_Db_Table_Row_Abstract {
        public function insert_user(array $data) {
        print_r($data);
        //$obj = new users();
        }   
    }
?>

我创建了一个表单，然后从控制器传递从表单到模型的数据，然后模型将数据插入到数据库中。

但是，如果我尝试创建用户类的对象，则会产生致命错误。

Fatal error: Uncaught exception 'Zend_Controller_Dispatcher_Exception' with message 'Invalid controller specified (error)

如果我尝试创建一个Application_Model_DbTable_User类，它工作正常，当我调用该类的方法时，它也可以正常工作，但是当我想将数据插入数据库时，它会生成致命错误如上所述。

这是我的控制器代码。

$data = array('first_name' => $request->getParam('first_name'),
              'last_name' => $request->getParam('last_name'),
                            'country' => $request->getParam('country'),
                            'address' => $request->getParam('address'),
                            'username' => $request->getParam('user_name'),
                            'password' => $request->getParam('password'),
                            'password' => $request->getParam('address'),
                            'date_created' => date('Y-m-d H:i:s')
              );
            //$tasksGateway = new users();

            $obj = new Application_Model_DbTable_User();
            $obj->insert_user($data);

这是确切的错误：

我认为您已删除ErrorController.php或未在默认模块中首先创建它。现在讨厌的是一些应用程序错误正在发生，因此ZF正在将控制器转移到ErrorController.php，但由于它不存在，你会遇到这样的致命错误。

错误控制器应该包含

class ErrorController extends Zend_Controller_Action
{

    public function errorAction()
    {
        $errors = $this->_getParam('error_handler');

        if (!$errors || !$errors instanceof ArrayObject) {
            $this->view->message = 'You have reached the error page';
            return;
        }

        switch ($errors->type) {
            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ROUTE:
            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_CONTROLLER:
            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ACTION:
                // 404 error -- controller or action not found
                $this->getResponse()->setHttpResponseCode(404);

                $this->view->message = 'Page not found';
                break;
            default:
                // application error
                $this->getResponse()->setHttpResponseCode(500);

                $this->view->message = 'Application error';
                break;
        }



        // conditionally display exceptions
        if ($this->getInvokeArg('displayExceptions') == true) {
            $this->view->exception = $errors->exception;
        }

        $this->view->request   = $errors->request;
    }




}

更新

你不能创建直接扩展Zend_Db_Table_Row_Abstract的类的实例，而应该使用table对象来实现例如

$user = new  Users();
$user->createRow()->insert_user($data);

而不是

$obj = new Application_Model_DbTable_User();
            $obj->insert_user($data);

致命错误：创建模型类对象时未捕获异常'Zend_Controller_Dispatcher_Exception'
