我可以使用PHP从表单发送数据并选择下拉列表发送电子邮件吗？

Question

I'm currently building a form in which a visitor inputs their information and submits it, in then sends an email across to the department that they've selected via the dropdown menu, just wanted to see if this is actually possible and if so how do i continue the IF statement, also is there anything wrong with my code, i'm no pro when it comes to html/php.

    <input type="text" name="full_name" placeholder="*Enter Name">

    <input type="email" name="email" placeholder="*Enter Email">

    <input type="text" name="company"  placeholder="*Enter Company">
    <br>

    <select id="Visiting">
     <option>Select Department to email</option>
      <option name="Visiting1" value="event1">Operations</option>
      <option name="Visiting2" value="event2">Security</option>
      <option name="Visiting3" value="event3">Shunters</option>  
      <option name="Visiting4" value="event2">Stock & Systems</option>
      <option name="Visiting5" value="event3">Goods In</option>  
      <option name="Visiting6" value="event3">Facilities</option>
      <option name="Visiting7" value="event3">IT</option>
      <option name="Visiting8" value="event3">Despacth</option>
      <option name="Visiting9" value="event3">Transport</option>
    </select>

    <br>
    <br>
    <br>

    <button type="submit">Sign In</button>

<?php
$name = $_POST['full_name'];
$email = $_POST['email'];
$company = $_POST['company'];
$visitor = $_POST['visitor'];

if($visitor == "security"){
    $mail_to = 'your security email';    
}elseif
  ($visitor == "it"){
    $mail_to = 'your it email';    
}else
  ($visitor == "Transport"){
$mail_to = 'your transport email';




$body_message = 'From: '.$name."\n";
$body_message .= 'E-mail: '.$email."\n";
$body_message .= 'Message: '.$company;
$body_message .= 'Message: '.$visitor;

$headers = 'From: '.$email."\r\n";
$headers .= 'Reply-To: '.$email."\r\n";

$mail_status = mail($mail_to, $subject, $body_message, $headers);

if ($mail_status) { ?>
<script language="javascript" type="text/javascript">
    alert('Thank you for notifying us, we will be with you shortly.');
    window.location = 'http://nameofwebsite.co.uk';
</script>
<?php
}
else { ?>
<script language="javascript" type="text/javascript">
    alert('Message failed. Please, try again or select another department');
    window.location = <'http://nameofwebsite.co.uk.>/';
</script>
<?php
}
?>

Your HTML is wrong, you can only add a name-attribute to a <select> -tag it doesn't work on <option> -tags.

Your html code should look like this:

<select id="Visiting" name="Visiting">
    <option disabled selected>Select Department to email</option>
    <option value="Visiting1">Operations</option>
    <option value="Visiting2">Security</option>
    <option value="Visiting3">Shunters</option>  
    <option value="Visiting4">Stock & Systems</option>
    <option value="Visiting5">Goods In</option>  
    <option value="Visiting6">Facilities</option>
    <option value="Visiting7">IT</option>
    <option value="Visiting8">Despacth</option>
    <option value="Visiting9">Transport</option>
</select>

PHP:

$visitor = $_POST['Visiting'];
    switch ($visitor) {
        case 'Visiting1':
        $mail_to = 'your Visiting1email';
        break;
    case 'Visiting2':
        $mail_to = 'your Visiting2 email';
        break;
    case 'Visiting3':
        $mail_to = 'your Visiting3 email';
        break;
    ...
}

I hope this helps

First of all, the PHP function mail() is probably the issue here if you are getting errors. You must have PHP set up to actually send emails, it doesn't typically work out-of-the-box without some configuration.

SMTP for sending emails is a very old protocol, and in it's original form it didn't require a username/password (authentication) to send an email. It was on the honor system that you weren't spoofing someone else in the "From:" field.

Obviously things have changed, and servers that receive email verify that the origin server matches the "From:" field on the email, and the origin server itself asks for a username/password to be able to send an email in the first place (and restricts the authenticated user's ability to customize the "From:" field as well).

This being said, you can run your own SMTP server and you can do so as insecurely as you like, but other email servers online won't take you very seriously because you'll look like just another spammer out there. Instead it's much more reliable to use an externally "properly" set up SMTP server through a web hosting company, or from a popular web mail service such as Gmail or Yahoo.

Under the hood, PHP's mail() function uses the Linux command line utility called sendmail . You can also use other libraries out there like PEAR's mail package.

A lot of people have sendmail using a default local SMTP server, and set up the that server as a relay to Gmail (or whatever) external server. This way scripts can send emails without a username/password (the relay takes care of that). Obviously this has some security implications, but it can be a simple way to do it.

If you let us know more about what email server you want to send mail from, and what type of server you website is running on, I could point you in the right direction for configuring a mail sending utility.
