CakePHP 2.x反向路由链接助手

标签: cakephp routing reverse routes view-helpers

在我的CakePHP App中,我连接了以下路线:

Router::connect('/:city/dealer/:id', 
    array('controller' => 'dealers', 'action' => 'view'),
    array(
        'pass' => array('city', 'id'),
        'city' => '[a-z]+',
        'id' => '[0-9]+'
        )
    );

这很有效,可以启用: domain.com/washington/dealer/1

但是如何在View的此URL中生成正确的HTML链接?如果我这样做:

echo $this->Html->link(
    'Testlink',
    array('washington', 'controller' => 'dealers', 'action' => 'view', 1)
);

它将所有参数添加到生成的链接的末尾:

http://domain.com/dealers/view/washington/1

我该如何正确地做到这一点?

我相信你仍然需要指定params,如下:

echo $this->Html->link('Testlink',
    array('controller' => 'dealers', 'action' => 'view', 'city' => 'washington',
                                                         'id'=> 1));

Cake在食谱中有一个类似的例子:

<?php
// SomeController.php
public function view($articleId = null, $slug = null) {
    // some code here...
}

// routes.php
Router::connect(
    '/blog/:id-:slug', // E.g. /blog/3-CakePHP_Rocks
    array('controller' => 'blog', 'action' => 'view'),
    array(
        // order matters since this will simply map ":id" to $articleId in your action
        'pass' => array('id', 'slug'),
        'id' => '[0-9]+'
    )
);

// view.ctp
// this will return a link to /blog/3-CakePHP_Rocks
<?php
echo $this->Html->link('CakePHP Rocks', array(
    'controller' => 'blog',
    'action' => 'view',
    'id' => 3,
    'slug' => 'CakePHP_Rocks'
));

嗨塞巴斯蒂安可能为时已晚,无法帮助你,但我可以帮助别人解决这个问题。解决问题的关键是在Helper类中添加url方法。我是通过在View / Helper中创建AppHelper.php来实现的。看起来像这样。我为你的城市更改了我的参数。

查看/助手/ AppHelper.php

<?php
App::uses('Helper', 'View');
class AppHelper extends Helper {

    function url($url = null, $full = false) { 
            if (is_array($url)) { 
                   if (empty($url['city']) && isset($this->params['city'])) { 
                            $url['city'] = $this->params['city']; 
                    }

                    if (empty($url['controller']) && isset($this->params['controller'])) { 
                            $url['controller'] = $this->params['controller']; 
                    }

                    if (empty($url['action']) && isset($this->params['action'])) { 
                            $url['action'] = $this->params['action']; 
                    }
            } 

            return parent::url($url, $full); 
    }

 }
 ?>

然后我创建像

这样的路线
Router::connect('/:city/dealer/:id', 
array('controller' => 'dealers', 'action' => 'view', 'id'=>':id'),
array('pass' => array('city', 'id'),
      'city' => '[a-z]+',
      'id' => '[0-9]+'
));

希望这会有所帮助:)
