Adding a subject line to PHP form - php

Question

So I've put a contact form into my site but I can't seem to add a subject line. (I'm SUPER new to PHP so I'm only about 40% sure of what I'm doing. The rest of the time I'm just learning through trial and error).
Here's what I have for the form:
<?PHP
require_once("./include/fgcontactform.php");
$formproc = new FGContactForm();
$formproc->AddRecipient('email address');
$formproc->AddSubject('Website Communication:');
$formproc->SetFormRandomKey('boQQEtSLenwppBa');
if(isset($_POST['submitted']))
{
if($formproc->ProcessForm())
{
$formproc->RedirectToURL("thank-you.php");
}
}
?>
<!-- Form Code Start -->
<form id='contactus' action='<?php echo $formproc->GetSelfScript(); ?>' method='post' accept-charset='UTF-8'>
<fieldset >
<legend>Contact us</legend>
<input type='hidden' name='submitted' id='submitted' value='1'/>
<input type='hidden' name='<?php echo $formproc->GetFormIDInputName(); ?>' value='<?php echo $formproc->GetFormIDInputValue(); ?>'/>
<input type='text' class='spmhidip' name='<?php echo $formproc->GetSpamTrapInputName(); ?>' />
<div class='short_explanation'>* required fields</div>
<div><span class='error'><?php echo $formproc->GetErrorMessage(); ?></span></div>
<div class='container'>
<label for='name' >Your Full Name*: </label><br/>
<input type='text' name='name' id='name' value='<?php echo $formproc->SafeDisplay('name') ?>' maxlength="50" /><br/>
<span id='contactus_name_errorloc' class='error'></span>
</div>
<div class='container'>
<label for='email' >Email Address*:</label><br/>
<input type='text' name='email' id='email' value='<?php echo $formproc->SafeDisplay('email') ?>' maxlength="50" /><br/>
<span id='contactus_email_errorloc' class='error'></span>
</div>
<div class='container'>
<label for='message' >Message:</label><br/>
<span id='contactus_message_errorloc' class='error'></span>
<textarea rows="10" cols="50" name='message' id='message'><?php echo $formproc->SafeDisplay('message') ?></textarea>
</div>
<div class='container'>
<input type='submit' name='Submit' value='Submit' />
</div>
</fieldset>
</form>
I added the $formproc->AddSubject('Website Communication:'); segment but it doesn't seem to be working and I'm wondering if there's something I'm missing?

What you're really asking is how to use a specific library class that you've downloaded from the Internet! If you look into the code of the class you're including at the top (which I assume is the same as this?) then you'll see it's automatically generating a subject line here:
$this->mailer->Subject = "Contact form submission from $this->name";
The reason your AddSubject function doesn't work is because that behaviour doesn't exist within the class.
If you want to change this behaviour, you'll have to change the class. You'll want to change the above line to something like
$this->mailer->Subject = $this->getSubject();
and implement a getSubject() method, similar to the GetFromAddress() one.
Better yet, create your own mailer class! Look into the PHP mail function to get started!
