PHP 获取下拉列表选择选项值
在我的下拉列表中,每个选项都有两个不同的值.我怎样才能检索两者?让我来说明一下我的意思.
In my dropdownlist I have two different values for each option. How can I retrieve both? Let me illustrate what I mean.
<select name="my_ddl">
<option value="<?php $value_Id ?>"><?php $value_text ?></option>
<option value="<?php $value_Id ?>"><?php $value_text ?></option>
</select>
当表单发布时,我希望能够同时获取所选选项的 $value_id 和 $value_text.我该怎么做?
When the form is posted, I want to be able to get both the $value_id and $value_text of the selected option. How can I do this?
$_POST['my_ddl'] 只能得到一个值,不能同时得到两个值.
$_POST['my_ddl'] only gets one value not both.
在 asp.net 中,我可以通过引用 my_ddl.Value 和 my_ddl.Text 来做到这一点.
In asp.net I could do this simply by referring to my_ddl.Value and my_ddl.Text.
谢谢!
推荐答案
严格来说,这是不可能的.
Strictly, this is not possible.
你可以做的是在你的value
属性中使用一个分隔符:
What you could do is use a delimiter in your value
attribute:
<select name="my_ddl">
<option value="<?php echo $value_Id ?>|<?php echo $value_text ?>"><?php echo $value_text ?>
</option>
</select>
还有……
<?php
list($id, $text) = explode('|', $_POST['my_ddl']);
//...
?>
