Question

您好我已经创建了一个文件上传表单，除了我按下提交时它完全正常工作，它不会将我重定向到Uploads / add.ctp，但它确实将文件保存到目录中数据库。实际上，如果我指向重定向上传/浏览它仍然不需要我上传/浏览。

这是我的控制器

public function add() {

if(!empty($this->data)){

    $file = $this->request->data['Upload']['file'];
if ($file['error'] === UPLOAD_ERR_OK && $this->Upload->save($this->data)){
    $this->Upload->save($this->data);
    if(move_uploaded_file($file['tmp_name'],APP.'webroot/files/uploads'.DS.$this->Upload->id.'.mp4')) {
    $this->Session->setFlash(__('<p class="uploadflash">The upload has been saved</p>', true));
    $this->redirect(array('controller'=>'Uploads','action' => 'add'));
    } else{

    $this->Session->setFlash(__('<p class="uploadflash">The upload could not be saved. Please, try again.</p>', true));

    }
} 


}
}

这是我的表格

      <div class="maincontent">
      <?php echo $this->Form->create('Upload', array('type' => 'file', 'class'=>'uploadfrm'));?>
<fieldset class='registerf'>
    <legend class='registerf2'>Upload a Video</legend>
<?php
    echo 'Upload your video content here, there is no size limit however it is       <b>.mp4</b> file format only.';
    echo '<br/>';
    echo '<br/>';
    echo $this->Form->input('name', array('between'=>'<br />', 'class'=>'input'));
    echo $this->Form->input('eventname', array('between'=>'<br />'));
    echo $this->Form->input('description', array('between'=>'<br />', 'rows'=> '7', 'cols'=> '60'));
    echo  $this->Form->hidden('userid', array('id' => 'user_id','value' => $auth['id']));
    echo $this->Form->hidden('username', array('id' => 'username', 'value' => $auth['username']));
    echo $this->Form->input('file', array('type' => 'file'));
    echo "<br/>"
?>
<?php echo $this->Form->end(__('Submit', true));?>
</fieldset>

     <?php

   class UploadsController extends AppController {
   public $name = 'Uploads';

      public $helpers = array('Js');



// Users memeber area, is User logged in…
 public $components = array(
    'Session',
    'RequestHandler',
    'Auth'=>array(
        'loginRedirect'=>array('controller'=>'uploads', 'action'=>'browse'),
        'logoutRedirect'=>array('controller'=>'users', 'action'=>'login'),
        'authError'=>"Members Area Only, Please Login…",
        'authorize'=>array('Controller')
    )
  );


       public function isAuthorized($user) {
            // regular user can access the file uploads area
        if (isset($user['role']) && $user['role'] === 'regular') {
            return true;
             }

             // Default deny
                return false;
            }





function index() {
        $this->set('users', $this->Upload->find('all'));

有什么建议吗？

Answer 1

这个add函数在你的UploadsController中，对吗？并且您希望它重定向到上传/浏览？

在您的UploadsController中，$name设置为什么？

<?php
class UploadsController extends AppController {
   public $name = ?; // What is this variable set to?
}

通过Cake的Inflector，当您在重定向中指定控制器时，它应该是小写的：

$this->redirect(array('controller' => 'uploads', 'action' => 'browse'));

或者，如果您指向的操作和要指向的操作位于同一个控制器中，则甚至不需要指定控制器。例如，如果您从UploadsController add()提交表单，并且想要重定向到browse()：

$this->redirect(array('action' => 'browse'));

尝试一下，看看它是否有帮助。

另请注意，您在add函数中两次调用$ this-＆gt;上传 - >保存（$ this-＆gt;数据）。

public function add() {

    if(!empty($this->data)){
        $file = $this->request->data['Upload']['file'];
        if ($file['error'] === UPLOAD_ERR_OK && $this->Upload->save($this->data)) {
            $this->Upload->save($this->data);
            if(move_uploaded_file($file['tmp_name'],APP.'webroot/files/uploads'.DS.$this->Upload->id.'.mp4')) {
                $this->Session->setFlash(__('<p class="uploadflash">The upload has been saved</p>', true));
                $this->redirect(array('controller'=>'Uploads','action' => 'add'));
            } else {
                $this->Session->setFlash(__('<p class="uploadflash">The upload could not be saved. Please, try again.</p>', true));
            }
        }
    } 

}

具体来说，这里：

if ($file['error'] === UPLOAD_ERR_OK && $this->Upload->save($this->data)) {
    $this->Upload->save($this->data);
    ...

当您在if条件下调用它时，它仍会将数据保存到数据库中。删除第二个就可以了。

如果我在函数add

中添加以下行

            $this->render();

一切都很完美，我为我的生活而努力解决为什么我必须渲染视图，如果肯定所有其他视图都是默认呈现的。但无论如何让它工作！希望这有助于其他人：）
