PHP Build a Basic PHP Website (2018) Enhancing a Form Displaying the Error Message

Empty Fields Error Not Display On The Screen (PHP)

My error messages for if a form field is blank, doesn't show on the page instead it submits the form. I am validating it from the server side, because I am trying to prevent blank fields from being submitted into my MySQL database. I also have JavaScript turned off.

if($_SERVER["REQUEST_METHOD"] == "POST"){
    $Fname      =  $_POST["Fname"];
    $Lname      =  $_POST["Lname"];
    $email      =  $_POST["email"];
    $address1   =  $_POST["address1"];
    $address2   =  $_POST["address2"];
    $city       =  $_POST["city"];
    $state      =  $_POST["state"];
    $zip_code   =  $_POST["zip"];
    $phone      =  $_POST["phone"];
    $distance   =  $_POST["distance"];  

    //form php validation blank error messages 
    if($Fname == "" || $Lname == "" || $email == "" || $address1 == "" || $city == "" || $state == "" || $zip_code == "" || $phone == ""){
        $msg =  "<p class='error'>The required fields cannot be blank</p>";
        }
        else if(!filter_var($email, FILTER_VALIDATE_EMAIL)  && !isset($msg)){ //email validation 
                 $msg = "<p class='error'>You must place a real email address</p>";
                }else{
                        require_once("inc/admin_login.php");  //log in database file
                        $query = "INSERT INTO runner(fname,lname,email,address1,address2,city,state,postcode,phone,distance) VALUES('$Fname','$Lname','$email','$address1','$address2','$city','$state','$zip_code','$phone','$distance')";
                        $result=mysqli_query($con,$query);

                            if($result){  //if successfull logining in to database message
                                $msg = "<h2 class='notice'>Thank You For Signing Up</h2>"; 
                            }else{

                            }// end if
                        }//end else
