Question

我有两张表Location和Car，我想要的是：

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

Answer 1

您必须使用cakephp id帮助程序在网址中传递汽车的Html。

在/Views/Car/view.ctp添加

中

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

在Controllers/locations_controller.ctp

中

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

<强>更新

在您看来，更改此声明

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

到这个

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

请注意我假设你的图片文件夹结构，告诉我这是否有效。

Answer 2

this is LocationsController


<?php
App::uses('AppController', 'Controller');

class LocationsController extends AppController {


	
	public $components = array('Paginator', 'Session');
	public $helpers = array(

		'GoogleMap'

	public function index() {

	}


	public function view($id = null) {

			throw new NotFoundException(__('Invalid location'));
		}

	}


	public function add($car_id) {

	}


	public function edit($id = null) {

	}


	public function delete($id = null) {
		$this->Location->id = $id;

		$this->request->allowMethod('post', 'delete');

		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) {

	}


	public function admin_add() {

	}


	public function admin_edit($id = null) {

		return $this->redirect(array('action' => 'index'));
	}}



and this CarsController






<?php
App::uses('AppController', 'Controller');
 
class CarsController extends AppController {

 
	public $components = array('Paginator', 'Session');

 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) {

			throw new NotFoundException(__('Invalid car'));
		}
		$options = array('conditions' => array('Car.' . $this->Car->primaryKey => $id));

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

		}
		$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) {

	}

public function index() {

	}

}
