Selecting different recipient

[Mercer]

I am trying to modify a form so that a different recipient is chosen based on a drop-down box selection. I'm sure it's just me, but I feel like I'm breaking my brain trying to figure this out.

The basic form fields are Name, Email, Subject, Subject Matter, and Comments. Name, Email, and Subject are user-inputable text boxes, Subject Matter is the drop-down box, and Comments is a textarea.

What I want is for the user to select from the drop down box, and based on their selection, the email will go to a different address.

ie: User selects subject matter 'A', email goes to a@a.com. User selects subject matter 'B', email goes to b@b.com.

How would I do this using process.php?

Thanks in advance.

In the process.php you will find a line that starts with "mail(".
just above this line put in something like this:
if($a=="a"){
mail("a@a.com",...
Then just below end the if statement with a close bracket
}

Copy these lines and paste below and change the if statement to something like:
else if($a=="b"){
mail("b@b.com",...
}
else {
mail("a@a.com",...
}

Without details of the process.php I can not be too specific but you should get the general idea.  If you still need help come back and post again.

Having a bit of trouble figuring out where exactly to put the lines you mentioned; I got a syntax error when I placed where I thought it ought to go. Here's the edited version of process.php before adding the above...Any help is greatly appreciated, and I thank you so much for being willing to help those of us who aren't so familiar with php.

<?php
include("global.inc.php");
$errors=0;
$error="The following errors occured while processing your form input.<ul>";
pt_register('POST','Name');
pt_register('POST','Email');
pt_register('POST','Subject');
pt_register('POST','Department');
pt_register('POST','Comments');
$Comments=preg_replace("/(\015\012)|(\015)|(\012)/","&nbsp;<br />", $Comments);if($Name=="" || $Email=="" || $Subject=="" || $Department=="" || $Comments=="" ){
$errors=1;
$error.="<li>You did not enter one or more of the required fields. Please go back and try again.";
}
if($errors==1) echo $error;
else{
$where_form_is="http".($HTTP_SERVER_VARS["HTTPS"]=="on"?"s":"")."://".$SERVER_NAME.strrev(strstr(strrev($PHP_SELF),"/"));
$message="Name: ".$Name."
Email: ".$Email."
Subject: ".$Subject."
Department: ".$Department."
Comments: ".$Comments."
";
$message = stripslashes($message);
mail("a@a.com","$Subject",$message,"$Email");

header("Refresh: 0;url=thanks.html");
?><?php
}
?>

You still have to fill in the blanks but here it is:

<?php
include("global.inc.php");
$errors=0;
$error="The following errors occured while processing your form input.<ul>";
pt_register('POST','Name');
pt_register('POST','Email');
pt_register('POST','Subject');
pt_register('POST','Department');
pt_register('POST','Comments');
$Comments=preg_replace("/(\015\012)|(\015)|(\012)/","&nbsp;<br />", $Comments);
if($Name=="" || $Email=="" || $Subject=="" || $Department=="" || $Comments=="" ){ $errors=1;
$error.="<li>You did not enter one or more of the required fields. Please go back and try again."; }
if($errors==1) echo $error;
else{
$where_form_is="http".($HTTP_SERVER_VARS["HTTPS"]=="on"?"s":"")."://".$SERVER_NA
ME.strrev(strstr(strrev($PHP_SELF),"/"));
$message="Name: ".$Name."
Email: ".$Email."
Subject: ".$Subject."
Department: ".$Department."
Comments: ".$Comments."
";
$message = stripslashes($message);

if($Department=="FILL_IN_THE_BLANK") {
// First case email according to first department selection
mail("a@a.com","$Subject",$message,"$Email");
} else if($Department=="FILL_IN_THE_BLANK") {
// Second case email according to second department selection
mail("b@b.com","$Subject",$message,"$Email");
} else {
// Third case is the default in case of any mixup in the department selection
mail("a@a.com","$Subject",$message,"$Email");
}
