在CakePHP 2.x中使用命名参数

我有以下方法来查询我的笔记:

function search( $q = null )
{
    if ( $q == null )
    {
        $this->redirect(array('action' => 'index'));
    }

    $this->paginate = array(
    'limit'=>5,
    'order'=>'Note.datetime DESC',
    'conditions' => array(
        'OR' => array(
            'Note.title LIKE' => '%'. $q . '%',
            'Note.content LIKE' => '%'. $q . '%'
            )
        ),
        'Note.status'=>1
    );

    $this->set('notes', $this->paginate());

    $this->render('index');
}

正如您所看到的,它需要一个名为“q”的参数来查询模型数据。

我把它连接到路由器就像这样:

Router::connect('/notes',
    array('controller'=>'notes','action'=>'index', 'page' => 1),
    array(
        'pass' => array('page')
    )
);

Router::connect('/notes/page/:page', 
    array('controller' => 'notes', 'action' => 'index'),
    array(
        'pass' => array('page'),
        'page' => '[1-9]+'
        )
);

Router::connect('/notes/search/:page/:q',
    array('controller'=>'notes','action'=>'search', 'page' => 1),
    array(
        'pass' => array('page','q')
    )
);

Router::connect('/notes/search/:q/page/:page', 
    array('controller' => 'notes', 'action' => 'search'),
    array(
        'pass' => array('page','q'),
        'page' => '[1-9]+'
        )
);

这样我应该获取网址:

domain.com/notes - loads page 1 of notes

domain.com/notes/page/2 - loads page 2 of notes

domain.com/notes/search/Hello - searches for Hello in notes

domain.com/notes/search/Hello/page/2 - shows page 2 of the above search

视图中的寻呼机如下所示:

<?php if(isset($this->request->params['named']['q'])) { ?>
<?php $this->Paginator->options(array('url'=>array('controller' => 'notes', 'action' => $action, 'q' => $this->request->params['named']['q']))); ?>
<?php } else { ?>
<?php $this->Paginator->options(array('url'=>array('controller' => 'notes', 'action' => $action))); ?>
<?php } ?>

它对索引方法工作正常,但是对于搜索方法来说,它变得很混乱,因为当我进行搜索时,它不会像预期那样将寻呼机与路由匹配。例如,我正在获取domain.com/notes/search/2/:q

等网址

此外,我真的不喜欢在if语句中包装paginator选项,所以如果我能让它自动找出url那将是非常棒的,因为它很麻烦必须这样做,似乎是导致以上问题。

我已将命名参数连接到路由器顶部,如下所示:

Router::connectNamed(array('q'));

答案 0 :(得分:2)

最后,我选择使用POST代替GET进行搜索,以便所有内容都在服务器端进行处理,而不是使用杂乱的URL重写并尝试变聪明。

这是我制作表格的样子:

<?php echo $this->Form->create('search', array('url'=>array('controller'=>'notes','action'=>'search'),'class'=>'search')); ?>
    <label class="placeholder" for="q">Search</label>
    <?php if( isset($q) ) { $term = $q; } else { $term = ''; } ?>
    <?php echo $this->Form->input('q', array('label'=>false,'id'=>'q','value'=>$term)); ?>
    <button type="submit" class="btn ss-icon ss-search"></button>
<?php echo $this->Form->end(); ?>

搜索方法:

function search()
{
    if ($this->request->is('post')) {

        $this->Session->write('q', $this->request->data['search']['q']);

        $this->redirect(array('action' => 'search'));

    } else {

        $q = $this->Session->read('q');

        $this->paginate = array(
        'limit'=>5,
        'order'=>'Note.datetime DESC',
        'conditions' => array(
            'OR' => array(
                'Note.title LIKE' => '%'. $q . '%',
                'Note.content LIKE' => '%'. $q . '%'
                )
            ),
            'Note.status'=>1
        );

        $this->set('q',$q);

        $this->set('action','search');

        $this->set('notes', $this->paginate());

        $this->render('index');

    }

}

和路线:

Router::connect('/notes/search',
    array('controller'=>'notes','action'=>'search', 'page' => 1),
    array(
        'pass' => array('page')
    )
);
Router::connect('/notes/search/page/:page', 
    array('controller' => 'notes', 'action' => 'search'),
    array(
        'pass' => array('page'),
        'page' => '[1-9]+'
        )
);

我清理会话,如果在AppController中正在使用任何其他页面但搜索方法:

if(strpos($this->here, Router::url(array('controller'=>'notes','action'=>'search'))) === 0 ) {

    //echo 'yes';

} else {

    $this->Session->delete('q');

}

这给了我一些网址:

domain.com/notes - 加载第1页的笔记

domain.com/notes/page/2 - 加载说明的第2页

domain.com/notes/search - 在笔记中搜索Hello(存储在会话中)

domain.com/notes/search/page/2 - 显示上述搜索的第2页
