$ _POST值以外的另一个属性 [英] $_POST another attribute than value

问题描述

是否可以通过$ _POST获得除名为value的属性以外的其他属性的值

Is it possible to get some other attribute's value than attribute named value with $_POST

example: <option value="FusRo" name="Dah"></option>

通常，当我使用$ _POST ['Dah']时，PHP会获取FusRo(值).

Normally when i use $_POST['Dah'] The php grabs FusRo (the value).

但是我想获取另一个属性的值，而不是名为value的属性.我希望你能理解.

But I want to grab another attribute's value than attribute named value. I hope you understand.

如果我不能使用$ _POST来获取其他值，那我可以使用其他命令吗?

If I cant use $_POST to grab some other value, is it some other comand i can use?

另一个例子: 如果我使用

Another example: If i use

<option value="FusRo" name="Dah"></option>

我可以用$ _POST代替"Fusro"来获得"Dah"吗?

Can I get the "Dah" with $_POST instead of "Fusro" ?

推荐答案

您可以将其他值放在隐藏字段中

You can put your other value in a hidden field:

<input type="hidden" name="DahHidden" value="somethingelse" />

然后使用以下方法从$_POST获取它:

Then get it from $_POST with:

$_POST['DahHidden']

如果必须根据<select>中的内容动态更改此值，那么您将需要JavaScript.

If this value has to dynamically change based on what's in the <select>, then you'll need JavaScript.

如果您想从$_POST中获取键(即表单字段中的name属性)，则可以像这样遍历$_POST:

If you want to grab the keys from $_POST (i.e. the name attributes from your form fields), you can iterate over $_POST like this:

foreach( $_POST as $key => $value) 
    echo $key . ' => ' . $value; // Will print Dah => value (eventually)

请注意，遍历$_POST可能会产生比仅一个表单元素更多的输出(除非'Dah'是您在表单中提交的唯一内容.

Note that iterating over $_POST will likely produce more output than just that one form element (unless 'Dah' is the only thing you submitted in your form.
