<?php echo $this->Form->create('Movie'); ?>
    <?php echo __('Add Movie'); ?>
    <?php

    echo $this->Form->input('title');
    echo $this->Form->input('date', array(
        'type'  => 'date',
        'label' => 'Date',

表movies的表结构

    CREATE TABLE IF NOT EXISTS `movies` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `movie_id` int(11) NOT NULL,
  `title` varchar(100) NOT NULL,
  `file` varchar(200) NOT NULL,
  `date` date NOT NULL,
  `description` text NOT NULL,
   PRIMARY KEY (`id`),
   UNIQUE KEY `movie_id` (`movie_id`),
   KEY `id` (`id`)
  ) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ;

创建位于/app/Model/Movies.php的模型

  <?php
  class Movie extends AppModel {

  }
  ?>

在app / Controller / Movies.php中创建控制器

<?php 
class MoviesController extends AppController {
    public function add() {
    if ($this->request->is('post')) {
        $maxId = $this->Movie->find('first', array(
            'order' => 'movie_id DESC',
            'fields' => array('Movie.movie_id')
        ));
        $maxId = (isset($maxId['Movie']['movie_id'])? $maxId['Movie']['movie_id'] : 0);
        $this->request->data['Movie']['movie_id'] = $maxId+1;

        $folderToSaveFiles = WWW_ROOT . 'img/uploads/' ;

        if(!empty($this->request->data['Movie']['file']))
        {
            $file = $this->request->data['Movie']['file'];
            $ext = substr(strtolower(strrchr($file['name'], '.')), 1);
            $arr_ext = array('jpg', 'jpeg', 'gif','png');
            if(in_array($ext, $arr_ext))
            {
                $newFilename = $this->request->data['Movie']['title'].'.'.$ext;                 
                $result = move_uploaded_file( $file['tmp_name'], $folderToSaveFiles . $newFilename );
                $this->request->data['Movie']['file'] = $newFilename;
                $this->Movie->save($this->request->data);
                //debug($this->request->data);
            }
        }
    }
}

注意：在app / webroot / img / uploads /＆amp;中创建一个目录上传目录必须是写权限。
