Question

我是CakePHP的新手，我现在正试图获取表格中的所有行＆＃34;流派＆＃34;和＆＃34;主题＆＃34;填写一些复选框，但是当我尝试foreach时，我总是得到以下错误：

通知（8）：未定义的变量：类型[APP / View / Pages / register.ctp，第88行]

警告（2）：为foreach（）提供的参数无效[APP / View / Pages / register.ctp，第88行]

注意（8）：未定义的变量：主题[APP / View / Pages / register.ctp，第98行]

警告（2）：为foreach（）提供的参数无效[APP / View / Pages / register.ctp，第98行]

然而，我设置了＃genies＆＃39;和＆＃39;主题＆＃39;在我的GenresController和ThemesController但我不断收到此错误。这是我的代码：

register.ctp

<div id='stream'>
            <?php
            foreach ($genres as $genre):
                echo $this->Form->checkbox('Genre.0.libelle', array(
                    'value' => $genre['Genre']['id'],
                    'name' => $genre['Genre']['libelle']
                ));
            endforeach;
            ?>
        </div>
        <div id='webserie'>
            <?php
            foreach ($themes as $theme):
                echo $this->Form->checkbox('Theme.0.libelle', array(
                    'value' => $theme['Theme']['id'],
                    'name' => $theme['Theme']['libelle']
                ));
            endforeach;
            ?>
        </div>

GenresController：

App::uses('AppController', 'Controller');

/**
 * CakePHP GenresController
 * @author Sen
 */
class GenresController extends AppController {

    public function index() {

        $this->set('genres', $this->Genre->find('all'));
    }

}

ThemesController：

App::uses('AppController', 'Controller');

/**
 * CakePHP ThemesController
 * @author Sen
 */
class ThemesController extends AppController {

    public function index($id) {
        $this->set('themes', $this->Theme->find('all'));
    }

}

我试图将数组设置为$ genres，但它表示我的GenresController索引没有定义：

$genres = array();
$genres[0]['libelle'] = "Lamb";
$genres[1]['libelle'] = "Ham";

提前感谢您的帮助。

Answer 1

App::uses('AppController', 'Controller');

class PagesController extends AppController {
     public $uses = Array('Genre');

     public function register() {
         $this->set('genres', $this->Genre->find('all'));
     }
}

添加以上代码以在页面控制器中注册操作，不要忘记使用模态

Answer 2

class GenresController extends AppController {
    public $uses = array('Genre','Theme');

    public function index() {
         $this->render('register');
         $this->set('genres', $this->Genre->find('all'));
         $this->set('themes', $this->Theme->find('all'));
    }

}

CakePHP Foreach不起作用
