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);
?>
输出为
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>
我想删除这个
<option value=""></option>
默认情况下有空白选项：

您可以传入$attributes数组来修改该行为：
如果您希望显示自己的默认选项，请将字符串值添加到$attributes变量中的"empty"键，或者将其设置为false以关闭默认的空选项
所以，我假设这可以做到：
<?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);
?>
