Sending and retriving an email using a php form - php

Question

I am attempting to retrieve a sender's email, sender's name, mail subject, and mail message sent.
You will also see in the code i want to check if the name, email address, and message of a sender are not empty using empty()function. If one of them are empty, i want to display an error message in the document. Otherwise, call send_email() function.
Right now my output is displaying parts of my code. I need help with the formatting or maybe I am missing a step.
<?php
require_once ('c:/wamp64/www/Lab6/PHPMailerAutoload.php');
function sendEmail($fromEmail,$fromName,$subject, $message){
$mailer = new PHPMailer;
$mailer->isSMTP();
$mailer->Host = 'smtp.gmail.com';
$mailer->Port = 587;
$mailer->SMTPSecure = 'tls';
$mailer->SMTPAuth = true;
$mailer->Username= "geogumd#gmail.com";
$mailer->Password= "gis#umd2016";
$mailer->From= $fromEmail;
$mailer->FromName=$fromName . "(" . $fromEmail . ")";
$mail->IsHTML(true);
$mailer->Subject=$subject;
$mailer->Body=$message;
$mailer->addAddress('worthem.aleah#terpmail.umd.edu', 'Aleah');
$mailer->Sendmail($fromEmail,$fromName,$subject,$message);
if(!$mailer->send()) {
$h = "Mailer Error " . $mailer->ErrorInfo;
$m = "Mailer Error was not sent";
print "<h1>$h</h1>";
print "<pre>$m</pre>";
}else{
print "<h1>Mail Sent</h1>";
print "<p>Thank you. Your message has been sent successfully.</p>";
}
}
?>
<div id="content">
<?php
$user_input1 = $_POST['From'];
$user_input2 = $_POST['FromName'];
$user_input3 = $_POST['Subject'];
$user_input4 = $_POST['Body'];
if(!empty($user_input1) && is_string($user_input1)&&
(!empty($user_input2) && is_string($user_input2))&&
(!empty($user_input3) && is_string($user_input3))&&
(!empty($user_input4) && is_string($user_input4))
)
{
sendEmail($user_input1, $user_input2, $user_input3, $user_input4);
}
else{
print "<h4>Sorry</h4>";
print "<p>You didnt fill out the form completley. <a href='index.php?action=sendmail'>Try Again";
}
?>
