如何在Cakephp中使用数组选项获取数组值而不是索引表单输入

Question

我遇到了一个问题。我有一个表单和表单字段名称card_number。 card_number来自数据库。提交card_number的入境卡号。在我的ctp文件中，我写了这个。

<div class="form-group">
    <label class="col-sm-2 control-label"> Entry Card Number </label>
    <div class="col-md-10">
        <?php echo $this->Form->input('card_number', array('options' => $readCard,'class'=>'form-control','div'=>false,'label'=>false));?>
    </div> 
</div>

我已在Controller中编写此代码。我的观点看起来像上面的图像。

public function add_card_to_device($btsId = null){
    $readerData = $this->CardManagement->find('list',
        array(
            'conditions'    =>  array('site_name'=>$site_name),
            'fields'        =>  array('card_number'),
            'keyField'      => 'card_number',
            'valueField'    => 'card_number'    
        )
    );
    debug($readerData);
    $this->set('readCard', $readerData);
    if ($this->request->is('post')|| $this->request->is('put')) {
        $dataa          =   $this->request->data;
        print_r($dataa);
    }
}

单击“提交”按钮时出现问题。当我单击提交按钮时，我得到这些值。我得到了id值而不是card_number [card_number] =＆gt; 5a13b3d9-67ac-4847-b3f9-1870991894ac

Array ( [CardManagement] => Array ( [id] => 5a12d321-a7e0-4cf6-ab84-1870991894ac [site_name] => 1235 [card_number] => 5a13b3d9-67ac-4847-b3f9-1870991894ac ) )

但是我想要的输出看起来像这样。 [card_number] =＆gt; 6473088

Array ( [CardManagement] => Array ( [id] => 5a12d321-a7e0-4cf6-ab84-1870991894ac [site_name] => 1235 [card_number] => 6473088 ) )

请提出任何解决方案或建议。

Cakephp 3.x

调用list时，您可以分别使用keyField和valueField选项配置用于键和值的字段：

https://book.cakephp.org/3.0/en/orm/retrieving-data-and-resultsets.html#finding-key-value-pairs

    $readerData = $this->CardManagement->find('list',
        array(
            'conditions'    =>  array('site_name'=>$site_name),
            'fields'        =>  array('card_number'),
            'keyField'      => 'card_number',
            'valueField'    => 'card_number'
        )
    );

  

Cakephp 2.x

https://book.cakephp.org/2.0/en/models/retrieving-your-data.html#find-list

    $readerData = $this->CardManagement->find('list',
        array(
            'conditions' => array('site_name' => $site_name),
            'fields' => array('card_number','card_number'),
        )
    );
