Question

大家早上好。

我在发布表单时遇到问题：我的目标是使用我的表单上传许多文件，在我的模型中处理上传，但我甚至无法访问Model :: beforeSave（），因为我的请求不断变黑。这是代码。

查看：

echo $this->Form->create('Gallery', array('type' => 'file'));
echo $this->Form->hidden('id');
echo $this->Form->input('title', array(
    'required'  => true,
    'label'     => false,
    'class'     => 'form-control'
));
echo $this->Form->input('description', array(
    'required'  => true,
    'label'     => false,
    'type'      => 'textarea',
    'class'     => 'ckeditor'
));
echo $this->Form->input('photos.', array(
    'required'  => false,
    'label'     => false,
    'type'      => 'file',
    'class'     => 'form-control',
    'multiple'  => 'multiple'
));
echo $this->Form->end(array(
    'label'     => $button,
    'class'     => 'btn btn-default'
));

控制器：

public function admin_update($id = null) {
    if ($id != null && !$this->Gallery->exists($id)) {
        throw new NotFoundException('Elemento non valido');
    }
    if ($this->request->is(array('post', 'put'))) {
        if ($this->Gallery->save($this->request->data)) {
            $this->Session->setFlash('Galleria salvata', 'default', array(), 'good');
            return $this->redirect(array(
                'admin'     => true,
                'action'    => 'index'
            ));
        }
        $this->Session->setFlash('Non sono riuscito a memorizzare la galleria', 'default', array(), 'bad');
    }
    $this->request->data = $this->Gallery->findById($id);
}

型号：

App::uses('AppModel', 'Model');
App::uses('String', 'Utility');
class Gallery extends AppModel {
    public $useTable = 'gallery';
    public $displayField = 'title';
    public $validate = array(
        'title' => array(
            'notEmpty' => array(
                'rule' => array('notEmpty')
            )
        ),
        'description' => array(
            'notEmpty' => array(
                'rule' => array('notEmpty')
            )
        )
    );

    public function afterSave($created, $options = array()) {
        $dir = new Folder('img/galleries/' . $this->id, true, 0777);

        foreach ($this->data[$this->alias]['photos'] as $Photo) {
            move_uploaded_file($Photo['tmp_name'], 'img/galleries/' . $this->id . '/' . String::uuid()); // I'll add more controls later
        }
    }

    public function beforeDelete($cascade = true) {
        $dir = new Folder('img/galleries/' . $this->id);
        return $dir->delete();
    } 
}

因此，每次我尝试上传我的表单时，我的请求都会出现此错误

The request has been black-holed
Error: The requested address '/ciardi/admin/galleries/update' was not found on this server.

即使我尝试使用相同的代码上传单个图像，也会出现同样的问题。有没有办法在没有插件的情况下解决我的问题？请帮帮我:)。

解决了我的问题。我只是在我的数据库中添加了一个名为'images'的表和一个Image模型。 Gallery :: afterSave（）方法为我正在尝试上传的每个图像调用Image :: save（），Image :: beforeSave（）使用is_uploaded_file（）检查图像并将其移动到右侧dir和Image :: beforeDelete （）帮助我保持文件系统清洁。就是这样。

如何使用类型为'file'和'multiple'的<input />发布表单而不会使请求变黑？
