Zend framework 为什么我的模型函数在ZEND中不起作用？

我想知道我的代码有什么问题： 这是我的控制器的功能：

public function testareAction(){ 
    // $this->getResponse()->setHeader('Content-Type', 'application/json');
    $this->_helper->layout->disableLayout();
    $this->_helper->viewRenderer->setNoRender(true);
    //$myarray =  $_POST['data_post'];
    //$product_ids = $_POST['product_ids'];
    //$type = 1;
    $model = new Application_Model_Order(); 
    echo $model -> saveOrderNames();
}

public function indexAction()
    {
        if (!($locationUrl = $this->_getParam('locationUrl'))) {
            throw new \Zend_Controller_Action_Exception('Location URL was not provided.', 404);
        }        

        $this->maiDivClass = "block clear step1";

        // get Location row
        $mapper = new DbTable\Location();
        $sql = $mapper->select()->where('url = ?', $locationUrl);

        if (!($this->view->location = $mapper->fetchRowActive($sql))) {
            throw new \Zend_Controller_Action_Exception('Location not found', 404);
        }

        // set active markup for location menu
        $this->_helper->layout()->locationMainMenuUrl = $this->view->location->url;

        // SEO
        $this->setSeo(
            $this->view->location->meta_title, 
            $this->view->location->meta_description, 
            $this->view->location->meta_keywords
        );

        // get day from param
        $dayName = $this->_getParam('day', Cronos::getCurrentDayName());

        $this->view->dayNo = Cronos::getWeekDayNumber($dayName);
        if ($this->view->dayNo === false) {
            throw new \Zend_Controller_Action_Exception('Invalid weekday provided.', 404);
        }

        $this->view->selectedDate = Cronos::getDateWithOffset($this->view->dayNo); // get date offset

        $testCfg = Zend_Registry::get('Zend_Config')->custom->test->toArray();

                }
                for($day = 0; $day<$currentDay; $day++) {
                    $week[] = $day;
                }
            }

            $this->view->week = $week;

        $model = new Application_Model_OrderNames(); 
        echo "2<hr>";
        $model -> saveOrderNames();

}

这是我模型中的功能：

public function saveOrderNames(){
    return 1;
}

为什么我不能在浏览器中得到结果1？ 我是一个新手，所以请给我好的说明

thx:D 这是来自控制器的索引：

}

好的，我在models文件夹中创建了这个文件：OrderNames.php 这就是我的模型所包含的内容：

<?php
    class OrderNames {

        public function saveOrderNames(){
                 return 1;
                } 
    }   
?> 

这是控制器的功能：

    // $this->getResponse()->setHeader('Content-Type', 'application/json');
    $this->_helper->layout->disableLayout();
    $this->_helper->viewRenderer->setNoRender(true);
    //$myarray =  $_POST['data_post'];
    //$product_ids = $_POST['product_ids'];
    //$type = 1;
    $model = new Application_Model_Order(); 
    echo $model -> saveOrderNames();
}

        }

        $this->_helper->layout()->locationMainMenuUrl = $this->view->location->url;

        $model = new Application_Model_OrderNames(); 
        echo "2<hr>";
        $model -> saveOrderNames();

}

为什么字符串2tralala没有出现

您调用：$model=newapplication\u model\u ordername； php文件的名称是OrderNames.php 这个班是

class OrderNames {

    public function saveOrderNames(){
             return 1;
            } 
}   

因此，请尝试替换类的名称：

class Application_Model_OrderNames {...

---

采取有效的措施，粘贴代码，并将var_转储到debbug。也许是你的行动要求不好，也许是你的模型没有放在正确的目录中。您还应该在post变量中添加isset如果我使用var_dump$model->saveordername，它不会显示任何内容；是空的吗？如果是，尝试替换$model=新应用程序\模型\订单；echo$model->saveordername；由回声'福'；它也是空的，在$model=newapplication\u model\u Order之后显示的所有内容；是否将类名替换为OrderNamesTest，并将TestReaction中的代码替换为：$model=new Application\u model\u OrderNamesTest；。正如您所说，文件名仍然是OrderNames.php。我没有得到回音字符串，其他选项？没有，如果你想要一个foo模型，你必须在application/models中有一个foo.php。在Foo.php中，类必须是class Application\u Model\u Foo{…}，对Foo类的调用是new Application\u Model\u Foo{；
