Question

我的图片上传验证总是触发与要上传的文件的允许大小相关的消息，之后我将代码复制到验证数组的顶部，其中previouslly是is_valid规则，即使文件大小低于限制，甚至文件上传成功，也会始终触发。我的is_unique规则按预期工作，但其余的似乎总是被触发，即使文件遵守规则。什么是触发此行为？我正在使用CakePHP 2.4.4。

控制器

public function admin_upload_image(){
        $this->set('title_for_layout', 'Inserir Fotografias');
        if(!$this->Session->check('User')) {
            $this->Session->setFlash('Está a aceder a uma zona restrita. Por favor faça Login.');
            $this->redirect(array(
                            'controller' => 'users',
                            'action' => 'login'));
        }

        $this->layout = 'admin_index';
        if($this->request->is('post') || $this->request->is('put')) {
          /*  $file = $this->request->data['gallery_images']['path']['name'];*/
       //debug($this->request->data['gallery_images']['path']['name']);
       //die;
        $file = array(
                'GalleryImage' => array(
                'path' => $this->request->data['gallery_images']['path']['name']
                                        )
                );
            move_uploaded_file($this->data['gallery_images']['path']['tmp_name'], $_SERVER['DOCUMENT_ROOT'] . '/html/PushUp/app/webroot/img/gallery/' . $this->data['gallery_images']['path']['name']);

            $this->loadModel('GalleryImage');

            $this->GalleryImage->create();
           //debug($file);
           //die;
            if($this->GalleryImage->save($file)){
                $validationErrors = $this->GalleryImage->invalidFields();
                $this->Session->setFlash($validationErrors['path']); // named key of the rule
                $this->Session->setFlash('Fotografia guardada com sucesso.', 'default', array('class'=>'alert alert-success'));
            }
            //else{
                //debug($this->GalleryImage->invalidFields());
                //die;
                //$error = $this->Notification->validationErrors;
                //$this->set('error', $error);

                //$this->Session->setFlash(__($error), 'Flash/warning');
            //}
        }
    }

模型

<?php
App::uses('AppModel', 'Model');
class GalleryImage extends AppModel{
    public $displayField ='path';
    public $useTable = 'gallery_images';
    //public $actsAs = array('MultipleDisplayFields' => array('fields' => array('path', 'id')));
    var $name = 'GalleryImage';
    var $validate= array(
        'path' => array(

            'size' => array(

                'message' => 'O ficheiro deve ter um tamanho igual ou inferior a 1.5MB.',
                //'last' => true,

            'is_valid' => array(

Answer 1

您正在传递$ file变量以进行保存的 $这 - ＆GT; GalleryImage-＆GT;保存（$文件）

并且您手动设置此变量值

$file = array( 'GalleryImage' => array( 'path' => $this->request->data['gallery_images']['path']['name'] ) );

因此您不会将文件信息传递给您的模型。您必须将 $ this-＆gt; request-＆gt;数据[＆＃39; gallery_images＆＃39;] [＆＃39;路径＆＃39;] 传递给您的保存方法

验证始终是触发规则消息
