Cakephp 3.0 表单下拉列表如何显示级别

Cakephp 3.0 form dropdown how to show level

我正在尝试为性别添加一个表单字段,下面是我的代码:

$options = ['m' => 'Male', 'f' => 'Female']; echo $this->Form->select('gender', $options);

但是在我的视图文件中我无法看到 lebel 性别是否有任何其他代码可以帮助我建议。

From->select 没有给出正确的标签。只是做:

echo $this->Form->input('gender', array(
    'options' => $options,
    'type' => 'select',
    'empty' => 'Select the gender',
    'label' => 'Gender'
   )
);
 <?= $this->Form->select('gender', ['m' => 'Male', 'f' => 'Female'], ['class' => 'form-control', 'required' => true])?>
