Question

大家好，我正在使用cakephp创建表单。在这里，我使用了一个选择下拉列表。此下拉列表从数据库中填充。我有两个表，分支和员工。 Branch表中的PrimaryContactID是外键。这个选择下拉列表中填充了Employee表中的EmployeeID（截至目前）。但是，我需要，下拉列表应该显示名称，保存时我应该保存ID。

这就是我写的：

controller:
public function add()
    {
        $branch = $this->Branch->newEntity();
        if ($this->request->is('post')) {
            $branch = $this->Branch->patchEntity($branch, $this->request->data);
            if ($this->Branch->save($branch)) {
                $this->Flash->success(__('The branch has been saved.'));

                return $this->redirect(['action' => 'index']);
            } else {
                $this->Flash->error(__('The branch could not be saved. Please, try again.'));
            }
        }
        $employee = $this->Branch->Employee->find ( 'list', [ 
                'limit' => 200 
        ] );
        $this->set(compact('branch', 'employee'));
        $this->set('_serialize', ['branch']);
    }
BranchTable.php:
class BranchTable extends Table
{

    /**
     * Initialize method
     *
     * @param array $config The configuration for the Table.
     * @return void
     */
    public function initialize(array $config)
    {
        parent::initialize($config);

        $this->table('branch');
        $this->displayField('BranchID');
        $this->primaryKey('BranchID');

        $this->addBehavior('Timestamp');

        $this->belongsTo('Employee', [
                'foreignKey' => 'EmployeeID',
                'joinType' => 'INNER'
        ]);
    }
}
  add.ctp:
<div class="branch form large-9 medium-8 columns content">
    <?= $this->Form->create($branch) ?>
    <fieldset>
        <legend><?= __('Add Branch') ?></legend>
        <?php
            echo $this->Form->input('BranchName');
            echo $this->Form->input('BranchCode');
            echo $this->Form->input('Address');
            echo $this->Form->input('Telephone');
            echo $this->Form->input('PrimaryContactID', ['options' => $employee]);
        ?>
    </fieldset>
    <?= $this->Form->button(__('Submit')) ?>
    <?= $this->Form->end() ?>
</div>

截至目前，下拉列表中填充了EmployeeID的值。我需要的是，我需要同时拥有EmployeeID和EmployeeName。当我点击下拉列表时，我应该看到EmployeeName，在保存时我应该保存ID。

怎么做？我应该做的所有改变是什么？

Answer 1

调用列表时，您可以配置用于键和的字段分别使用keyField和valueField选项的值：

$employee = $this->Branch->Employee->find('list', [ 
    'keyField' => 'EmployeeID',
    'valueField' => 'EmployeeName',
    //'limit' => 200
]);

//write your query like this

$employee = $this->Branch->Employee->find('list')->select(['EmployeeID','EmployeeName']));
