如何在cakePHP 2x中上传帖子的多个图像

Question

我是CakePHP的新手，并且正在使用CakePHP 2x。我正在做一个项目，用户可以使用帖子上传多个图像。到目前为止，我无法上传文件。

这是我数据库的图像表：

post_id是外键。这是帖子模型：

<?php

class Post extends AppModel {
    // The $validate array tells CakePHP how to validate your data when the save() method is called
    public $belongsTo = array('Catagory','User');
    public $hasMany = array(
        'Image' => array(
            'className' => 'Image',
            'foreignKey' => 'post_id',
            'dependent' => false,
            'conditions' => '',
            'fields' => '',
            'order' => '',
            'limit' => '',
            'offset' => '',
            'exclusive' => '',
            'finderQuery' => '',
            'counterQuery' => ''
        )
    );

现在是Post控制器：

public function addPost() {

    if ($this->request->is('post')) {

        // pr ($this->request->data);
        //die();
        $rootfolder = WWW_ROOT . 'img/uploads/' ;



        if(!empty($this->request->data))
        {
                //Check if image has been uploaded
            if(!empty($this->request->data['Post']['Image']))
            {
                foreach ($this->request->data['Post']['Image'] as $i => $image) 
                {
                    $file = $this->request->data['Post']['Image'][$i];
                    $tmp = $file['tmp_name'];

                    // debug( $file);
                    // debug( $tmp );
                    // die();

                    $ext = substr(strtolower(strrchr($file['name'], '.')), 1); 
                    //get the extension

                    $arr_ext = array('jpg', 'jpeg', 'gif'); //set allowed extensions

                        //only process if the extension is valid
                    if(in_array($ext, $arr_ext))
                    {

                        $name = substr(md5(time()), 0,10).$i.'.'.$ext;
                        $path = $rootfolder.$name;
                        debug($name);
                        debug($path);
                        // die();
                        move_uploaded_file($tmp,$path);
                        $file = array('name'=>$file['name'],'path' => $path );
                        debug($file);

                        $images[] = $file;


                        // $this->data['Post']['image']['name'] = $file['name']

                        // $this->Post->data['Image']['image'];


                        // $this->data->Post['Image']['image'] = $file['name'];
                    }
                }
                debug($images);

                // die();                   

                //now do the save (optional)
            }    //if($this->Image->save($this->data)) {...} else {...}
        }



        $this->Post->create();
             // the save() method will check for validation errors and abort the save if any occur

            // pr ($this->request->data);
    //      die();
        $this->request->data['Post']['user_id'] = AuthComponent::user('id');

        if ($this->Post->saveAll($this->request->data)) {
            $this->Flash->success(__('Your post has been saved.'));
                // redirect function redirects to another URL
            return $this->redirect(array('action' => 'index')); 
        }
        $this->Flash->error(__('Unable to add your post.'));
    }
    $catagories = $this->Post->Catagory->find('list');
    $this->set(compact('catagories'));
    $image = $this->Post->Image->find('list');
    $this->set(compact('image'));
}

有人可以帮我完成这些吗？谢谢。
