问题描述
我想在我的 cakephp 3.0 应用程序中上传图片.但我收到错误消息:
I want to upload images in my cakephp 3.0 app. But I get the error message:
Notice (8): Undefined index: Images [APP/Controller/ImagesController.php, line 55]
是否已经有一些在 cakePHP 3.0 中上传文件(一次多个文件)的示例?因为我只能找到 cakePHP 2.x 的示例!
Are there already some examples for uploading files (multiple files at once) in cakePHP 3.0? Because I can only find examples for cakePHP 2.x !
我想我需要在我的 ImagesTable.php 中添加一个自定义验证方法?但我无法让它工作.
I think I need to add a custom validation method in my ImagesTable.php? But I can't get it to work.
图像表
public function initialize(array $config) { $validator ->requirePresence('image_path', 'create') ->notEmpty('image_path') ->add('processImageUpload', 'custom', [ 'rule' => 'processImageUpload' ]) } public function processImageUpload($check = array()) { if(!is_uploaded_file($check['image_path']['tmp_name'])){ return FALSE; } if (!move_uploaded_file($check['image_path']['tmp_name'], WWW_ROOT . 'img' . DS . 'images' . DS . $check['image_path']['name'])){ return FALSE; } $this->data[$this->alias]['image_path'] = 'images' . DS . $check['image_path']['name']; return TRUE; }
图像控制器
public function add() { $image = $this->Images->newEntity(); if ($this->request->is('post')) { $image = $this->Images->patchEntity($image, $this->request->data); $data = $this->request->data['Images']; //var_dump($this->request->data); if(!$data['image_path']['name']){ unset($data['image_path']); } // var_dump($this->request->data); if ($this->Images->save($image)) { $this->Flash->success('The image has been saved.'); return $this->redirect(['action' => 'index']); } else { $this->Flash->error('The image could not be saved. Please, try again.'); } } $images = $this->Images->Images->find('list', ['limit' => 200]); $projects = $this->Images->Projects->find('list', ['limit' => 200]); $this->set(compact('image', 'images', 'projects')); $this->set('_serialize', ['image']); }
图片添加.ctp
<?php echo $this->Form->input('image_path', [ 'label' => 'Image', 'type' => 'file' ] ); ?>
图像实体
protected $_accessible = [ 'image_path' => true, ];
