multi-recipient PHP email form not sending emails - php

Question

I'm trying to get my email form working, but something seems to be hanging up. it's not sending out emails at all!
For reference, this uses Wordpress, and this is the code:
<?php
$action=$_REQUEST['action'];
if ($action=="") /* display the contact form */
{
?>
<form action="#" method="POST" enctype="multipart/form-data">
<input type="hidden" name="action" value="submit">
Your name:<br>
<input name="username" type="text" value="" size="30"/><br>
Department:<br>
<select id="department" class="form-control-footer">
<option value="Email_0">Sales</option>
<option value="Email_1">Support</option>
<option value="Email_2">Website Feedback</option>
<option value="Email_3">Other</option>
</select><br>
Email Subject<br>
<input name="emailsubject" type="text" value="" size="30"/><br>
Your email:<br>
<input name="email" type="text" value="" size="30"/><br>
Your message:<br>
<textarea name="message" rows="7" cols="30"></textarea><br>
<input type="submit" value="Send email"/>
</form>
<?php
}
else /* send the submitted data */
{
$name=$_POST['username'];
if (($department=="Email_0"))
{
$mailto=$_POST['example#website.com'];
}
if (($department=="Email_1"))
{
$mailto=$_POST['example#website.com'];
}
if (($department=="Email_2"))
{
$mailto=$_POST['example#website.com'];
}
else
{
$mailto=$_POST['example#website.com'];
}
$emailsubject=$_POST['emailsubject'];
$email=$_POST['email'];
$message=$_POST['message'];
if (($name=="")||($email=="")||($message==""))
{
echo "All fields are required, please fill the form again.";
}
else{
$from="From: $name<$email>\r\nReturn-path: $email";
$subject="Webform : $emailsubject";
mail($mailto, $subject, $message, $from);
echo "Thank you for your email! Your email has been sent, and we will try to respond as soon as we can!";
}
}
?>
I've modified the base form to add in departments, which changes the recipient of the contact form. but in doing so, it seems the form no longer sends out those emails at all.
Anyone know what I've done wrong?

Here you need to add "name="department"" to the code below
<select id="department" name="department" class="form-control-footer">
Here you need to change your code as showed below:
if (($_POST['department'] == "Email_0"))
{
$mailto='example#website.com';
}
else if ($_POST['department'] == "Email_1")
{
$mailto = 'example#website.com';
}
