Question

您好我在PHP核心中做过类似的事情，但是尝试在cakephp中做同样的事情对我来说很难。我想获取标签输入，并爆炸POST数据，并使用由“，”分隔的每个标签的posts id将新数组插入到自己的表中。但是，当我在创建帖子时插入爆炸数组为空时。

add.ctp

echo $this->Form->create('Post');
echo $this->Form->input('title');
echo $this->Form->input('body', array('rows' => '3'));
echo $this->Form->input('tags', array('label' =>'Separate tags by commas'));
echo $this->Form->end('Save Post');

PostsController

public function add() {
    if ($this->request->is('post')) {
        $tags = $this->set($this->request->data['Post']['tags']);
        $exploded_tags = explode(",",$tags);

        $this->Post->create();

        if ($this->Post->save($this->request->data)) {
            $this->Session->setFlash(__('Your post has been saved.'));
            return $this->redirect(array('action' => 'index'));
        }
        $this->Session->setFlash(__('Unable to add your post.'));
    }
}

$this->set()用于将变量发送到CakePHP中的视图。您不需要它来检索数据。

public function add() {
    if ($this->request->is('post')) {
        $tags = $this->request->data['Post']['tags'];
        $exploded_tags = explode(",",$tags);

        $this->Post->create();

        if ($this->Post->save($this->request->data)) {
            $this->Session->setFlash(__('Your post has been saved.'));
            return $this->redirect(array('action' => 'index'));
        }
        $this->Session->setFlash(__('Unable to add your post.'));
    }
}

cakepp在爆炸功能后插入数组
