在CakePHP中创建搜索表单

<!-- search.ctp -->
<?php echo $this->Form->create(null, ['url' => ['controller' => 'Posts', 'action' => 'search']]); ?>
    <?php echo $this->Form->input('keyword', ['label' => '关键词']); ?>
    <?php echo $this->Form->submit('搜索'); ?>
<?php echo $this->Form->end(); ?>

// PostsController.php
public function search()
{
    $keyword = $this->request->getData('keyword');
    $query = $this->Posts->find('all')
        ->where(['title LIKE' => '%' . $keyword . '%']);

    $this->set('posts', $query);
}

// PostsController.php
public function index()
{
    // 加载search视图文件
    $this->render('search');
}
