如何在cakephp中自定义视图2

Question

我正在尝试创建一个汽车租赁网站，当客户预订汽车时我遇到了问题，必须在预订后从可用汽车的窗口拆除汽车，我有一张桌子＆＃39;汽车＆＃39和桌子＆＃39;地点＆＃39;，我想要的是当客户租车时，必须从汽车列表中取出汽车出租，这里是页面：/view/cars/index.ctp,/view / cars / view。 ctp，/ LocationsController.php，CarsController.php

＆＃13;

＆＃13;

view/cars/index.ctp : 

<div class="row">

	<?php foreach ($cars as $car):?>
 
	<div class="col-sm-6 col-md-4">
		<div class="">
			<?php echo $this->Html->link($this->Html->image($car['Car']['avatar']),
					array('action'=>'view',$car['Car']['id']),
					array('escape'=>false,'class'=>'thumbnail'));?>
			<div class="caption">
				<h5>
					<?php echo $car['Car']['title'];?>
				</h5>
				<h5> 
					Price: $
					<?php echo $car['Car']['price'];?>
				</h5>
                <h5><?php echo $this->Html->link(__('Rent a Car'), array('controller'=>'cars','action' => 'view', $car['Car']['id'])); ?></h5>
			</div>
		</div>
	</div>

	<?php endforeach;?>
  
  
  and the view/cars.view.ctp :
  
  <div class="cars view">
<h2><?php echo __('Car'); ?></h2>
    <dl>
		<dt><?php echo __('Id'); ?></dt>
		<dd>
			<?php echo h($car['Car']['id']); ?>
		</dd>
      <dt><?php echo __('Picture'); ?></dt>
		<dd>
			<?php echo h($car['Car']['picture']); ?>
		</dd>
		<dt><?php echo __('Price'); ?></dt>
		<dd>
			<?php echo h($car['Car']['price']); ?>
		</dd>
		
	</dl>
    </div>
    <?php 

echo $this->Html->image("cars/".$car['Car']['id'].".jpg", array(
    "alt" => "Cars",
    'url' => array('controller' => 'locations', 'action' => 'add', $car['Car']['id'])
));

 ?>
  
  //and the CarsController : 
  
  
  <?php
App::uses('AppController', 'Controller');
 
class CarsController extends AppController {

 
	public $components = array('Paginator', 'Session');

	public $helpers = array('Js', 'GoogleMap');


	
 public function view($id = null){
		if (!$this->Car->exists($id)) {
			throw new NotFoundException(__('Invalid car'));
		}
		
		$options = array('conditions' => array('Car.' . $this->Car->primaryKey => $id));
		$this->set('car', $this->Car->find('first', $options));
 		
 }

public function index() {
		$this->set('cars', $this->Car->find('all'));
	}

}


//and the LocationsController


<?php
App::uses('AppController', 'Controller');

class LocationsController extends AppController {


	
	public $components = array('Paginator', 'Session');
	public $helpers = array(
		'Js',

	public function index() {
		$this->Location->recursive = 0;

	}


	public function edit($id = null) {
