如何在 CakePHP 中定义变量并动态链接到 URL？

Question

我正在尝试从 cakephp 扩展到“博客教程”，但在链接到登录用户主页时遇到了一些问题，我在名为 view.ctp 的文件中创建了该主页。

我可以链接到我的大部分文件路径 http://localhost:8888/blogtest/users/view/，直到我需要 'id' 来定义也发送给某人的页面。

这是我链接到页面的方式：

<a href="/blogtest/users/view/<?php ?>">go</a>

我知道我需要在 php 标签中添加一些逻辑来告诉浏览器检索当前登录用户的 ID。

我该怎么做呢？我应该在哪里创建变量？*

var 是放在UsersController.php 中还是在User.php 中？非常感谢任何帮助！

UsersController php：

<?php

// app/Controller/UsersController.php
App::uses('AppController', 'Controller');



class UsersController extends AppController {

    public function beforeFilter() {
    parent::beforeFilter();
    // Allow users to register and logout.
    $this->Auth->allow('add', 'logout');
    }

    public function login() {
        if ($this->request->is('post')) {
            if ($this->Auth->login()) {
                return $this->redirect($this->Auth->redirectUrl());
            }
            $this->Session->setFlash(__('Invalid username or password, try again'));
        }
    }

    public function logout() {
        return $this->redirect($this->Auth->logout());
    }

    public function index() {
        $this->User->recursive = 0;
        $this->set('users', $this->paginate());
    }

    public function view($id = null) {
        $this->User->id = $id;
        if (!$this->User->exists()) {
            throw new NotFoundException(__('Invalid user'));
        }
        $this->set('user', $this->User->read(null, $id));
    }

    public function add() {
        if ($this->request->is('post')) {
            $this->User->create();
            if ($this->User->save($this->request->data)) {
                $this->Session->setFlash(__('The user has been saved'));
                return $this->redirect(array('action' => 'index'));
            }
            $this->Session->setFlash(
                __('The user could not be saved. Please, try again.')
            );
        }
    }

    public function edit($id = null) {
        $this->User->id = $id;
        if (!$this->User->exists()) {
            throw new NotFoundException(__('Invalid user'));
        }
        if ($this->request->is('post') || $this->request->is('put')) {
            if ($this->User->save($this->request->data)) {
                $this->Session->setFlash(__('The user has been saved'));
                return $this->redirect(array('action' => 'index'));
            }
            $this->Session->setFlash(
                __('The user could not be saved. Please, try again.')
            );
        } else {
            $this->request->data = $this->User->read(null, $id);
            unset($this->request->data['User']['password']);
        }
    }

    public function delete($id = null) {
        // Prior to 2.5 use
        // $this->request->onlyAllow('post');

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

        $this->User->id = $id;
        if (!$this->User->exists()) {
            throw new NotFoundException(__('Invalid user'));
        }
        if ($this->User->delete()) {
            $this->Session->setFlash(__('User deleted'));
            return $this->redirect(array('action' => 'index'));
        }
        $this->Session->setFlash(__('User was not deleted'));
        return $this->redirect(array('action' => 'index'));
    }

}

关注the blog tutorial text：

动作中的单条指令使用 set() 从 控制器到视图（我们将在接下来创建）。该行设置 名为“posts”的视图变量等于 Post 模型的 find('all') 方法。

It goes on here 并解释正是你想要什么：

        <td>
            <?php echo $this->Html->link($post['Post']['title'],
array('controller' => 'posts', 'action' => 'view', $post['Post']['id'])); ?>
        </td>

老实说，我怀疑你是否试图阅读它。如果您真的再次阅读了本节。 It is all there 非常详细。
