I am attempting to create a pop-up form for suggestions that will email me whenever somebody hits submit. I keep getting an error message stating "Fatal error: Uncaught Error: Call to a member function AddAddress() on null" here is my php file:
<?PHP
require_once("./include/fgcontactform.php");
$formproc = new FGContactForm();
$myemail="johndoe@gmail.com";
$formproc->AddRecipient($myemail); //<<---Put your email address here
$formproc->SetFormRandomKey('CnRrspl1FyEylUj');
if(isset($_POST['submitted']))
{
if($formproc->ProcessForm())
{
$formproc->RedirectToURL("thank-you.php");
}
}
?>
