PHP mail function 'from' address
提问by The Crazy Chimp
I'm not even sure this is possible, however what I'm trying to do is as follows. I have an HTML form that generates and email using a PHPscript. What I want is to recieve emails from this form to [email protected], then I want the fromaddress to appear as one of the fields in the form.
我什至不确定这是可能的，但是我正在尝试做的如下。我有一个 HTML 表单，它使用PHP脚本生成和发送电子邮件。我想要的是从这个表单接收电子邮件到[email protected]，然后我希望from地址显示为表单中的字段之一。
I have had a look around and found some useful information on this site. I'm not sure whether sendmail_fromcan be used in this situation, or if it does what I'm asking.
我环顾四周，在这个网站上找到了一些有用的信息。我不确定是否sendmail_from可以在这种情况下使用，或者它是否符合我的要求。
Is this possible, if so how?
这是可能的，如果可以，如何？

See this page on the same site (example 2): http://www.w3schools.com/php/func_mail_mail.asp
在同一站点上查看此页面（示例 2）：http: //www.w3schools.com/php/func_mail_mail.asp
You will have to set the headers of the message to include the From and other stuff like CC or BCC:
您必须设置消息的标题以包含发件人和其他内容，例如抄送或密件抄送：
<?php
$to = "[email protected]";
$subject = "My subject";
$txt = "Hello world!";
$headers = "From: [email protected]\r\n";
mail($to,$subject,$txt,$headers);
?>
Note that you have to separate the headers with a newline sequence "\r\n".
请注意，您必须使用换行序列分隔标题"\r\n"。

For a php mail script I have used this for contact forms:
对于 php 邮件脚本，我已将其用于联系表单：
$from = $_POST["from"]; //posted from the form.
mail("[email protected]", $subject, $message, "From:" . $from);
I have not used a sendmail_from in my php before, only a simple variable.
我之前没有在我的 php 中使用过 sendmail_from，只有一个简单的变量。
I hope this helps!
我希望这有帮助！

Any reason you cant do it in the email headers?
你有什么理由不能在电子邮件标题中做到这一点？
$to = '[email protected]';
$subject = 'my subject';
$message = 'hello';
$headers = 'From: '.$email_from_form. "\r\n";
mail($to, $subject, $message, $headers);
