如何在 cakephp 2.0 中保存我的产品 ID

Question

我有两个 table Location 和 Car ，我想要的是：

当我点击汽车图片时（查看/汽车/view.ctp）
重定向到位置添加表单（视图/位置/add.ctp），同时保留我之前选择的汽车 ID

Answer 1

你必须在 url 中传递汽车的 id，使用 cakephp Html 助手。

在你的/Views/Car/view.ctp中添加

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

在你的Controllers/locations_controller.ctp

function add($car_id){
    $this->set('car_id', $car_id);
    //Or do what ever you want with the id
}

更新

在你看来，改变这个说法

echo $this->Html->input("cars/car_id", array(
    "alt" => "Cars",
    'url' => array('controller' => 'locations', 'action' => 'add', 'car_id')
));

至此

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

请注意，我假设您的图像文件夹结构，请告诉我是否可行。

Answer 2

this is LocationsController


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

class LocationsController extends AppController {


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

 public function index() {
  $this->Location->recursive = 0;
  $this->set('locations', $this->Paginator->paginate());
 }


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


 public function add($car_id) {
  if ($this->request->is('post')) {
   $this->Location->create();
   $this->set('car_id', $car_id);
   if ($this->Location->save($this->request->data)) {
    $this->Session->setFlash(__('The location has been saved.'));
    return $this->redirect(array('action' => 'index'));
   } else {
    $this->Session->setFlash(__('The location could not be saved. Please, try again.'));
   }
  }
  $users = $this->Location->User->find('list');
  $agencies = $this->Location->Agency->find('list');
  $cars = $this->Location->Car->find('list');
  $this->set(compact('users', 'agencies', 'cars'));

  
   
  





 }


 public function edit($id = null) {
  if (!$this->Location->exists($id)) {
   throw new NotFoundException(__('Invalid location'));
  }
  if ($this->request->is(array('post', 'put'))) {
   if ($this->Location->save($this->request->data)) {
    $this->Session->setFlash(__('The location has been saved.'));
    return $this->redirect(array('action' => 'index'));
   } else {
    $this->Session->setFlash(__('The location could not be saved. Please, try again.'));
   }
  } else {
   $options = array('conditions' => array('Location.' . $this->Location->primaryKey => $id));
   $this->request->data = $this->Location->find('first', $options);
  }
  $users = $this->Location->User->find('list');
  $agencies = $this->Location->Agency->find('list');
  $cars = $this->Location->Car->find('list');
  $this->set(compact('users', 'agencies', 'cars'));
 }


 public function delete($id = null) {
  $this->Location->id = $id;
  if (!$this->Location->exists()) {
   throw new NotFoundException(__('Invalid location'));
  }
  $this->request->allowMethod('post', 'delete');
  if ($this->Location->delete()) {
   $this->Session->setFlash(__('The location has been deleted.'));
  } else {
   $this->Session->setFlash(__('The location could not be deleted. Please, try again.'));
  }
  return $this->redirect(array('action' => 'index'));
 }


 public function admin_index() {
  $this->Location->recursive = 0;
  $this->set('locations', $this->Paginator->paginate());
 }


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


 public function admin_add() {
  if ($this->request->is('post')) {
   $this->Location->create();
   if ($this->Location->save($this->request->data)) {
    $this->Session->setFlash(__('The location has been saved.'));
    return $this->redirect(array('action' => 'index'));
   } else {
    $this->Session->setFlash(__('The location could not be saved. Please, try again.'));
   }
  }
  $users = $this->Location->User->find('list');
  $agencies = $this->Location->Agency->find('list');
  $cars = $this->Location->Car->find('list');
  $this->set(compact('users', 'agencies', 'cars'));
 }


 public function admin_edit($id = null) {
  if (!$this->Location->exists($id)) {
   throw new NotFoundException(__('Invalid location'));
  }
  if ($this->request->is(array('post', 'put'))) {
   if ($this->Location->save($this->request->data)) {
    $this->Session->setFlash(__('The location has been saved.'));
    return $this->redirect(array('action' => 'index'));
   } else {
    $this->Session->setFlash(__('The location could not be saved. Please, try again.'));
   }
  } else {
   $options = array('conditions' => array('Location.' . $this->Location->primaryKey => $id));
   $this->request->data = $this->Location->find('first', $options);
  }
  $users = $this->Location->User->find('list');
  $agencies = $this->Location->Agency->find('list');
  $cars = $this->Location->Car->find('list');
  $this->set(compact('users', 'agencies', 'cars'));
 }


 public function admin_delete($id = null) {
  $this->Location->id = $id;
  if (!$this->Location->exists()) {
   throw new NotFoundException(__('Invalid location'));
  }
  $this->request->allowMethod('post', 'delete');
  if ($this->Location->delete()) {
   $this->Session->setFlash(__('The location has been deleted.'));
  } else {
   $this->Session->setFlash(__('The location could not be deleted. Please, try again.'));
  }
  return $this->redirect(array('action' => 'index'));
 }}



and this CarsController






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

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

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


 
 
 public function admin_index() {
  $this->Car->recursive = 0;
  $this->set('cars', $this->Paginator->paginate());
 }

 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 admin_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 admin_add() {
  if ($this->request->is('post')) {
   $this->Car->create();
   if ($this->Car->save($this->request->data)) {
    
     


    $this->Session->setFlash(__('The car has been saved.'));
    return $this->redirect(array('action' => 'index'));
   } else {
    $this->Session->setFlash(__('The car could not be saved. Please, try again.'));
   }
  }
  $categories = $this->Car->Category->find('list');
  $subcategories = $this->Car->Subcategory->find('list');
  $this->set(compact('categories', 'subcategories'));
  $this->set('categories', $this->Car->Subcategory->Category->find('list'));
 }

 
 public function admin_edit($id = null) {
  if (!$this->Car->exists($id)) {
   throw new NotFoundException(__('Invalid car'));
  }
  if ($this->request->is(array('post', 'put'))) {
   if ($this->Car->save($this->request->data)) {
    $this->Session->setFlash(__('The car has been saved.'));
    return $this->redirect(array('action' => 'index'));
   } else {
    $this->Session->setFlash(__('The car could not be saved. Please, try again.'));
   }
  } else {
   $options = array('conditions' => array('Car.' . $this->Car->primaryKey => $id));
   $this->request->data = $this->Car->find('first', $options);
  }
  $categories = $this->Car->Category->find('list');
  $subcategories = $this->Car->Subcategory->find('list');
  $this->set(compact('categories', 'subcategories'));
 }

 
 public function admin_delete($id = null) {
  $this->Car->id = $id;
  if (!$this->Car->exists()) {
   throw new NotFoundException(__('Invalid car'));
  }
  $this->request->allowMethod('post', 'delete');
  if ($this->Car->delete()) {
   $this->Session->setFlash(__('The car has been deleted.'));
  } else {
   $this->Session->setFlash(__('The car could not be deleted. Please, try again.'));
  }
  return $this->redirect(array('action' => 'index'));
 }

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

}



and this is cars/view.ctp : 







<div class="cars view">
<h2><?php echo __('Car'); ?></h2>

<?php 


echo $this->Html->input("cars/car_id", array(
    "alt" => "Cars",
    'url' => array('controller' => 'locations', 'action' => 'add', 'car_id')
));

 ?>

  </dd>
  
 </dl>
</div>
<h5><?php echo $this->Html->link(__('Rent a Car'), array('controller'=>'locations','action' => 'add')); ?></h5>








and this locations/add.ctp : 








<div class="locations form">
<?php echo $this->Form->create('Location'); ?>
 <fieldset>
  <legend><?php echo __('Add Location'); ?></legend>
 <?php
  echo $this->Form->input('status');
  echo $this->Form->input('departure_date');
  echo $this->Form->input('expected_return_date');

  echo $this->Form->input('car_id');

  //echo $this->$Session->read('Auth.User.username');

 <h3><?php echo __('Actions'); ?></h3>
 <ul>

  <li><?php echo $this->Html->link(__('List Locations'), array('action' => 'index')); ?></li>
