Question

我尝试按照CakePHP博客教程（http://book.cakephp.org/2.0/en/tutorials-and-examples/blog/blog.html）进行操作，除编辑方法外，一切正常。教程中指定的编辑功能似乎有效，但它不是更新旧条目，而是在数据库中创建一个新条目。（但是说它确实使用＆＃34更新了旧条目; Jop已更新＆＃34;消息）

我的源文件是：

edit.ctp

<html>
<!-- File: /app/View/Jobs/edit.ctp -->
<h1>Edit Job</h1>

<?php
echo $this->Form->create('Job');
echo $this->Form->input('type');
echo $this->Form->input('name');
echo $this->Form->input('company');
echo $this->Form->input('id', array('type' => 'hidden'));
echo $this->Form->end('Save Job');
?>
</html>

JobsController.php

class JobsController extends AppController 
    {
    public $helpers = array('Html', 'Form', 'Session');
    public $components = array('Session');

    public function index() 
    {
        $this->set('jobs', $this->Job->find('all'));
    }

    public function view($id=null) {
        if (!$id) 
        {
            throw new NotFoundException(__('Invalid job'));
        }

        $job = $this->Job->findById($id);
        if (!$job) 
        {
            throw new NotFoundException(__('Invalid job'));
        }
        $this->set('job', $job);
    }

    public function add() {
        if ($this->request->is('POST')) {
            $this->Job->create();
            if ($this->Job->save($this->request->data)) 
            {
                $this->Session->setFlash(__('Your job has been saved.'));
                return $this->redirect(array('action' => 'index'));
            }
            $this->Session->setFlash('Unable to add your job.');
        }
    }

    public function edit($id=null) {
        if (!$id) {
            throw new NotFoundException(__('Invalid job'));
        }

        $job = $this->Job->findById($id);

        if (!$job) {
            throw new NotFoundException(__('Invalid job'));
        }

        if ($this->request->is(array ('POST', 'PUT'))) {
            $this->Job->id = $id; 

            if ($this->Job->save($this->request->data)) {           
                $this->Session->setFlash(__('Job has been updated.'));
                return $this->redirect(array('action' => 'index'));
            }
            else {
                 $this->Session->setFlash(__('Unable to update the job.'));
            }

            if (!$this->request->data) {
                $this->request->data = $job;
            }

        }
    }

    public function delete($id) {
        if (!$id) {
            throw new NotFoundException(__('Invalid job'));
        }

        if ($this->request->is('GET')) {
            throw new MethodNotAllowedException();
        }

        if ($this->Job->delete($id)) {
            $this->Session->setFlash(__('Job has been deleted.'));
        }
        else {
            $this->Session->setFlash(__('Unable to delete job.'));
        }

        return $this->redirect(array('action' => 'index'));
    }
}

?>

Answer 1

如果其他人遇到此问题，这是适用于我的解决方案：

if (!$this->request->data) {
            $this->request->data = $job;
        }

缩进错误，它不应该在

之内

if ($this->request->is(array ('POST', 'PUT')))

阻止，但是在同一级别，即一个较少缩进的层。

Answer 2

请检查您缺少的edit.ctp页面。

<?php echo $this->Form->create('Job'); ?>

   <?php
    echo $this->Form->hidden('id', array('value' => $this->data['Job']['id'])); ?>

CakePHP中的编辑创建新条目而不是更新旧条目
