选择要在php邮件程序中使用的变量

Question

I'm using a simple php mailer for my sites contact form. I have a form asking first for their subject of contact, and if they select a spesific option, then the recipient selection will fade in and you can select the recipient you want to use. BUT. I don't want to write the email addresses in the code, because of spam. So I'm trying to achieve this via php variables.

My mailer looks like this:

<?php
$var1="[e-mail]";
$var2="[e-mail]";
$to = "$_POST[kohde]";
$subject = "$_POST[asia]";
$message = "
$_POST[tiedot]

$_POST[nimi]
$_POST[email]
$_POST[puhelin]
IP-osoite: $_POST[ip] ";
$from = "xxx.fi";
$headers = "From:" . $from;
mail($to,$subject,$message,$headers);
?>

But using the variable names as is in value wont work. So how would I select the email to use with the option without hard coding the email to the option value?

 <select name="kohde" style="width:233px;" >
    <option value="$var1">xxx.fi</option>
    <option value="$var">Sivun tekijälle</option>
    </select>

Answer 1

I would do it this way...

Use this PHP to get the $to address:

$goodAddresses = array(1 => '[e-mail]', 2 => '[e-mail]');
$to = '[e-mail]';
if(isset($goodAddresses[$_POST['kohde']])) {
    $to = $goodAddresses[$_POST['kohde']];
}

And change the values of your select options in our html file to match the array keys in the PHP:

<select name="kohde" style="width:233px;" >
    <option value="1">xxx.fi</option>
    <option value="2">Sivun tekijälle</option>
</select>
