Question

我在cake php中使用该代码来创建下拉列表

<?php
   $selected = 'Select';
   $options = array('Select' => 'Select', 'New' => 'New', 'Used Dealer' => 'Used Dealer', 'Used Private' => 'Used Private');
   echo $this->Form->select('car_type', $options, $selected);
   ?>

输出

 select id="UsersCarType" name="data[Users][car_type]">
 <option value=""></option>
 <option selected="selected" value="Select">Select</option>
 <option value="New">New</option>
 <option value="Used Dealer">Used Dealer</option>
 <option value="Used Private">Used Private</option>
 </select>

我想删除此

<option value=""></option>

默认为空白选项：

您可以传入$ attributes数组来修改该行为：

如果您希望显示自己的默认选项，请将您的字符串值添加到$ attributes变量中的'empty'键，或将其设置为false以关闭默认的空选项

所以，我假设这样做：

<?php
    $selected = 'Select';
    $options = array('Select' => 'Select', 'New' => 'New', 'Used Dealer' => 'Used Dealer', 'Used Private' => 'Used Private');
    $attributes = array('empty' => false);
    echo $this->Form->select('car_type', $options, $selected, $attributes);
?>

额外的<option>标签显示在<select> </select> </option>中
