I am a newbie in CakePHP 1.3... I want to display or show the USER's username instead of USER's id, who post the COMMENTS in the POST view... Anyone can help me please?

Here is the model association I made:

  1. POSTS 'has many' COMMENTS
  2. COMMENTS 'belongs to' USERS

POST->COMMENT->USER

I already read the Containable Behavior of CakePHP 1.3, but still I can't understand it well... Please help me what codes to put in the post_controller's view & view.ctp that can show the related's related table in the POST view.

And How to call the USER's data in the POST view.

I'm still confused.

Thanks in Advance, Azure

假设

您有如下三个表

(1) Posts
    *  id
    *  title

(2) Comments
    * id
    * post_id
    * user_id

(3) Users
    * id
    * name

在PostsController.php文件中查看函数

public function view($id) {
    if (!$id) {
        throw new NotFoundException(__('Invalid post'));
    }

    $this->Post->recursive=2;
    $post = $this->Post->findById($id);
    if (!$post) {
        throw new NotFoundException(__('Invalid post'));
    }
    $this->set('post', $post);
}

app/View/Posts/ 文件夹中view.ctp文件的内容

<!-- File: /app/View/Posts/view.ctp -->
<h1><?php echo 'Post ID : '.h($post['Post']['id']); ?></h1>
<h1><?php echo 'Post Title : '.h($post['Post']['title']); ?></h1>
<?php 
echo 'Comments By Users : ';
if(!empty($post['Comment'])){
    foreach ($post['Comment'] as $key=>$value){?>
    <p>User Name : <?php echo $value['User']['name'];?></p>
    <?php }
}
else {
    echo '<br/>';
    echo 'No Comments Yet';
} ?>

模型文件:User.php

<?php
class User extends AppModel {
    public $hasMany = array(
        'Comment' => array(
                'className' => 'Comment',
        )
);
}
?>

模型文件:Comment.php

<?php
class Comment extends AppModel {
public $belongsTo = array(
        'User' => array(
                'className' => 'User',
                'foreignKey' => 'user_id'
        )
);
}
?>

模型文件:Post.php

<?php
class Post extends AppModel {
public $hasMany = array(
        'Comment' => array(
                'className' => 'Comment',
        )
);
}
?>

我假设您将用户 ID 保存在评论表中,并且用户名在发布评论的用户表中,然后使用以下解决方案

在控制器方法中:

$userdata=$this->User->find('all',array('fields'=>array('id','username'),'recursive'=>-1));
$userid=Set::extract('/User/id', $userdata);
$username=Set::extract('/User/username', $userdata);
$data=array_combine($username,$userid);
$this->set('name',$data);

在视图中:

$cid=$var['Comment']['user_id'];
$username=array_search($cid, $name);
echo $username;
