Cakephp 3.0 $ query-> toArray(); [英] Cakephp 3.0 $query->toArray();

问题描述

嘿，我试图找到一个解决方案，我正在使用以下命令从mysql检索数据:

Hey I am trying to find a solution I am retrieving the data from mysql using this command :

$meals = TableRegistry::get('Users');
$query = $meals
->find()
->select(['id' ,'username'])
->where(['role' => 'patient']);
 $data = $query->toArray();

这是使用query-> toarray()之后的代码，我得到了这个值

This is my code after using query->toarray() I am getting this value

 { "id": 4, "username": "s2" }  

我想将此值放在我的表单中，如下所示:

I want to put this value in my form which is like this :

   echo $this->Form->input('user_id', [
        'options' => [1 => 'Admin', 2 => 'Author']
    ]) ;

如何使用foreach来获取ID和用户名作为任何快速解决方案的名称

推荐答案

使用find('list')

$users = TableRegistry::get('Users')
    ->find('list', ['valueField' => 'username'])
    ->select(['id' ,'username'])
    ->where(['role' => 'patient']);

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

echo $this->Form->input('user_id', [
    'options' => $users
]);
