如何使用表单将表单外的变量发送到PHP文件？
问题描述：
I've got a page where I have a form that gets sent on to a php file that renders an email with the information and sends it on.
However, there are variables in the url (form.php?a=12&b=hello) that I also need to send.
I don't like the idea of having a hidden input field with this value or something like this. Is there a way to send it in a way that I can just $_REQUEST($a) and $_REQUEST($b) in the email rendering script?
我有一个页面，我有一个表格被发送到一个php文件，该文件呈现一封电子邮件 信息并发送。 p>
但是，我还需要发送url中的变量（form.php？a = 12＆amp; b = hello）。 p>
我不喜欢使用此值或类似的隐藏输入字段的想法。 有没有办法在电子邮件呈现脚本中以$ _REQUEST（$ a）和$ _REQUEST（$ b）的方式发送它？ p> div>
答
Yes, you can. $_REQUEST contains both the $_POST and $_GET data, so you were already on the right track;
$_REQUEST['a']; // from the url
$_REQUEST['field_1']; // posted from <input name="field_1" />
