I have written a script mail.php to handle the validation of form data and to send the form data via email. I have been testing this script by entering known invalid data however the script does not echo the error messages and just sends the data anyway.

Here is the form html:

<form method="post" action="mail.php" class="col-12" id="form-book">
 <div class="row">
 <div class=" form-group col-12">
 <p>Fill out the form below to tell me about your problem. <strong>Any problems to do with technology, all the solutions.</strong> Just tell me what you can, however the more info you give the better.</p>
 </div>
 <div class="form-group col-6">
 <label></label>
 <input id="name" name="name" placeholder="Name" type="text" required="required" class="form-control here bottom"> <span class="error"> <?php echo $nameErr; echo $nameErrEmpty;?></span>
 </div>
 <div class="form-group col-6">
 <label></label>
 <input id="phone" name="phone" placeholder="Phone#" type="text" required="required" class="form-control here bottom"> <span class="error"> <?php echo $phoneErr; echo$phoneErrEmpty;?></span>
 </div>
 <div class="form-group col-12">
 <label></label>
 <input id="email" name="email" placeholder="Email (Optional)" type="text" class="form-control here bottom"> <span class="error"> <?php echo $emailErr; echo $emailErrEmpty;?></span>
 </div>
 <div class="form-group col-6">
 <input data-provide="datepicker" id="date" name="date" placeholder="Pick a date" required="required" class="form-control here bottom"> <span class="error"> <?php echo $dateErr; echo $dateErrEmpty;?></span>
 </div>
 <div class="form-group col-6">
 <input type="text" id="time" name="time" placeholder="Choose the best time" required="required" class="form-control here bottom timepicker"> <span class="error"> <?php echo $timeErr; echo $timeErrEmpty;?></span>
 </div>
 <div class="form-group col-12">
 <label></label>
 <textarea id="message" name="message" cols="40" rows="5" class="form-control" required="required" aria-describedby="messageHelpBlock"></textarea> <span class="error"> <?php echo $messageErr; echo $messageErrEmpty;?></span>
 <span id="messageHelpBlock" class="form-text text-muted">Tell me a little about whats going on or what you need help with.</span>
 </div>
 <div class="form-group col-12">
 <button name="submit" type="submit" class="btn btn-primary">Send your message</button>
 </div>
 </div>
 <!--row-->
 </form>

Here is mail.php:

 <?php
 error_reporting(-1);
 ini_set('display_errors', 'On');
 set_error_handler("var_dump");

 date_default_timezone_set("Pacific/Honolulu");

 if (isset($_POST['submit'])) 
 $name = $_POST['name'];
 $phone = $_POST['phone'];
 $email = $_POST['email'];
 $date = $_POST['date'];
 $time = $_POST['time'];
 $message = $_POST['message'];
 $subject = "Appointment Booked";

 $mailTo = "itguy@johnpuaoi.com";

 $email = filter_var($email, FILTER_SANITIZE_EMAIL);

 function test_input($data) 
 $data = trim($data);
 $data = stripslashes($data);
 $data = htmlspecialchars($data);
 return $data;
 


 if (empty($name)) 
 $nameErrEmpty = "Your name is required";
 elseif (is_int($name)) 
 $nameErr = "That is not a valid name";
 else 
 $nameTested = test_input($name);
 

 if (empty($phone)) 
 $phoneErrEmpty = "Your phone number is required";
 elseif (is_int($name)) 
 $phoneTested = test_input($phone);
 else 
 $phoneErr = "Phone Number needs to be in this format e.x 1234567890";
 

 if (empty($email)) 
 $emailErrEmpty = "Your name is required";
 elseif (filter_var($email, FILTER_VALIDATE_EMAIL)) 
 $emailErr = "That is not a valid email";
 else 
 $emailTested = test_input($name);
 

 if (empty($message)) 
 $messageErrEmpty ="You must tell me about your problem";
 else 
 $messageTested = test_input($message);
 


 $dateTested = test_input($date);
 $timeTested = test_input($time);

 $headers = "From: ".$emailTested;
 $txt = "An appointment was booked by ".$nameTested.".nn".$dateTested." @".$timeTested.".nn".$messageTested;

 mail($mailTo, $subject, $txt, $headers);
 header("Location: index.php?mailsend");
 
 ?>

I have searched stack for similar issues but have found none. I am a total noob to php so any help would be appreciated. Thanks!
