致命错误：在Zend框架中找不到类2 [英] Fatal error : class not found in Zend framework 2

问题描述

我被困在zend框架中，我是新的，试图实现一个网站只是为了学习它。所以我的网站是关于比萨饼。当我尝试添加比萨饼，发送表单数据后，我得到这个错误消息说：致命错误：类'PizzaPoint\Controller\Pizza'没有找到C：\wamp\www\pizzalast\module \PizzaPoint\src\PizzaPoint\Controller\PizzaController.php在第27行，在这一行正好实例化一个对象类Pizza，它位于模型文件夹中。

I'am stuck in zend framework , i am new to it and trying to implement a website just to learn it . So my website is about pizzas . when I try to add a pizza , after sending form data , i get this error message saying : Fatal error: Class 'PizzaPoint\Controller\Pizza' not found in C:\wamp\www\pizzalast\module\PizzaPoint\src\PizzaPoint\Controller\PizzaController.php on line 27 , at this line exactly i instantiate an object of the class Pizza which is located in the " Model " folder .

这是来自披萨控制器的添加操作：

this the add action from the pizza controller :

public function addAction()
    {
    $form = new PizzaForm();
    $form->get('submit')->setValue('Add');

    $request = $this->getRequest();
    if($request->isPost())
        {
        $pizza = new Pizza();
        $form->setInputFilter($pizza->getInputFilter());
        $form->setData($request->getPost());

            if($form->isValid())
                {
                    $pizza->exchangeArray($form->getData());
                    $this->getPizzaTable()->savePizza($pizza);
                }       
        }   
    return array('form' => $form);
    }

这些是Pizza.php文件的前40行代码： / p>

these are the first 40 lines of code of the Pizza.php file :

namespace PizzaPoint\Model;

use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;

use Zend\InputFilter\InputFilterInterface;

class Pizza implements InputFilterAwareInterface {

public $id;
public $title;
public $zutaten;
public $smallprice;
public $bigprice;
public $familyprice;
public $partyprice;

protected $inputFilter;

public function exchangeArray($data)
    {
        $this->id            = (!empty($data['id']))         ? $data['id']         : null;
        $this->title         = (!empty($data['title']))      ? $data['title']      : null;
        $this->zutaten       = (!empty($data['zutaten']))    ? $data['zutaten']    : null;
        $this->smallprice    = (!empty($data['smallprice'])) ? $data['smallprice'] : null;
        $this->bigprice      = (!empty($data['bigprice']))   ? $data['bigprice']   : null;
        $this->familyprice   = (!empty($data['familyprice']))? $data['familyprice']: null;
        $this->partyprice    = (!empty($data['partyprice'])) ? $data['partyprice'] : null;
    }

public function getArrayCopy()
    {
        return get_object_vars($this);
    }
public function setInputFilter(InputFilterInterface $inputFilter)
    {
        throw new \Exception("Not used");
    }

我认为我应该负担的第三件事是module.php文件

the third thing i think i should afford here is the module.php file

namespace PizzaPoint;

use PizzaPoint\Model\Pizza;

use PizzaPoint\Model\PizzaTable;

use Zend\Db\ResultSet\ResultSet;

use Zend\Db\TableGateway\TableGateway;

class Module {

public function getAutoloaderConfig()
    {
        return array('Zend\Loader\ClassMapAutoloader'=>array(__DIR__ . '/autoload_classmap.php',),
        'Zend\Loader\StandardAutoloader'=>array('namespaces'=>array( __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__ , ),),);
    }
public function getConfig()
    {
    return include __DIR__ . '/config/module.config.php';   
    }

public function getServiceConfig()
    {
        return array(
          'factories' => array(
              'PizzaPoint\Model\PizzaTable' => function($sm) 
                    {
                        $tableGateway = $sm->get('PizzaTableGateway');
                        $table = new PizzaTable($tableGateway);
                        return $table;
                    },
               'PizzaTableGateway' => function ($sm)
                    {
                       $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
                       $resultSetPrototype = new ResultSet();
                       $resultSetPrototype->setArrayObjectPrototype(new Pizza());
                       return new TableGateway('pizza', $dbAdapter, null, $resultSetPrototype); 
                    },
              ),
            );
    }

}

最后这里是根的结构：

module 

----- \Application

-----\Application

------ \ PizzaPoint

------\PizzaPoint

    2. -----\config



              3 ------\ module.config.php

    2------\src
                   3 ------\PizzaPoint
                           4 --------\Controller
                                    5 -------\PizzaController.php
                           4---------\Form
                                     5--------\PizzaForm.php
                           4 ---------\Model
                                    5--------\Pizza.php
                                    5--------\PizzaTable.php

推荐答案

由于您的控制器位于 PizzaPoint\Controller 命名空间中，当您运行 new Pizza（）时，PHP认为您的意思是 new PizzaPoint\Controller\Pizza（）。您要使用全局命名空间：

Since your controller is within the PizzaPoint\Controller namespace, when you run new Pizza(), PHP thinks you mean new PizzaPoint\Controller\Pizza(). You either want to use the global namespace:

new \PizzaPoint\Model\Pizza()

或更好地添加：

use PizzaPoint\Model\Pizza;

到控制器类的顶部（在命名空间声明下面），将该类导入当前命名空间。然后您现有的代码应该工作。

to the top of the controller class (below the namespace declaration) to import that class into the current namespace. Then your existing code should work.
