Question

在阅读并应用所有关于下拉列表的建议答案后，我的下拉列表仍然没有结果。即时新手，这真的让我头痛解决这个问题。我有与belongsTO Client_Group表关联的客户端表。无论我对命名约定做了什么代码修改，我仍然无法将CLIENT GROUP的数据显示在我的下拉列表中。请帮忙！请帮忙！提前谢谢

CREATE TABLE `clients` (
  `id` int UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  `client_group_id` int ,
  `client_package_id` int ,
  `client_account_id` int ,
  `name` VARCHAR(40), 

CREATE TABLE `client_groups` (
  `id` INTEGER NOT NULL AUTO_INCREMENT  PRIMARY KEY,
  `name` VARCHAR(50), 

    INSERT INTO `client_groups` (`id`,`name`) VALUES (1,'Top Company Holdings');
    INSERT INTO `client_groups` (`id`,`name`) VALUES (2,'Cadiz Group of Companies');

In CLient Model:

    public $belongsTo = array(
         'ClientGroup' => array(
            'className'    => 'ClientGroup',
            'foreignKey'   => 'client_group_id' ,
            'fields'       =>   'name'
             ),

Client Group Model:
     public $hasMany = array(      
        'Client' => array(
            'className'     => 'Client',
            'foreignKey'    => 'client_group_id',
            'order'         => 'Client.name DESC' )

在客户端控制器中： $ clientgroups = $ this-＆gt; Client-＆gt; ClientGroup-＆gt; find（'list'，array（'type'=＆gt;'select'， '字段'=＆GT;数组（'id'，'name'）， 'order'=＆gt; array（'name'=＆gt;'ASC'）））; $这 - ＆gt;设置（紧凑（ 'clientgroups'））;

In Client Add.ctp :
    <?php echo $this->Form->input('client_group_id',array( 'option'=>$clientgroups ,  
               'type'=>'select', 'empty'=>'Select Group'));
    ?>

Answer 1

您有与belongsTO Client_Group表关联的客户端表。你想显示客户群＆＃39;数据到我的下拉列表。

$ clientGroup = $ this-＆gt; CLient Model-＆gt; Client Group Model-＆gt; find（＆＃39; list＆＃39;）; $这 - ＆gt;设置（紧凑（＆＃39; clientGroup＆＃39;））;

并在您的ctp页面中执行此操作

echo $ this-＆gt; Form-＆gt; input（＆＃39; client_group_id＆＃39;）;

Answer 2

您是否尝试过使用驼峰式情况设置变量？ $clientGroups和'clientGroups'？这是正确的命名约定。

他们的约会很疯狂!!试着这样工作，好吗？ ;）

CREATE TABLE `clients` (
  `id` int UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  `group_id` int ,
  `package_id` int ,
  `account_id` int ,
  `name` VARCHAR(40)
)

CREATE TABLE `groups` (
  `id` INTEGER NOT NULL AUTO_INCREMENT  PRIMARY KEY,
  `name` VARCHAR(50)
)

INSERT INTO `groups` (`id`,`name`) VALUES (
 1,'Top Company Holdings'
);
INSERT INTO `groups` (`id`,`name`) VALUES (
 2,'Cadiz Group of Companies'
);

In CLient Model:

public $belongsTo = array(
     'Group' => array(
        'className'    => 'Group',
        'foreignKey'   => 'group_id'
     )
);

In your Cliente controller

public function myFunction()
{
...
$groups = $this->Cliente->Group->find('list');
$this->set(compact('groups'));
...
}

In your view
echo $this->Form->input('group_id');
