Check mysqli Insert Query excuted ok and display message and send email - php

Question

I am creating a registration form for a project, nothing secure or advanced, i am still fairly new to php etc.
I insert the data needed to into a login table and a customer tbl, the data inserts fine. But i cant get the code to check that its worked and fire off a an email and display a message to the user.
I have tried using a value retrieved from the database which would only be there is the user registered successfuly.
if($userID != null)
{
$msg1 = "Thank You! you are now registered, please check your email for a verification link to verify your new account! ";
$col1 = "green";
//require_once "Mail.php";
require_once "inc/email.php";
}
I have also tried this
if($query)
{
$msg1 = "Thank You! you are now registered, please check your email for a verification link to verify your new account! ";
$col1 = "green";
//require_once "Mail.php";
require_once "inc/email.php";
}
Thanks,
Edit - Here is all the code,
<?php
include ("inc/mysql.php");
error_reporting(0);
$msg = "";
$col = 'green';
function test_input($data){
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
// define variables and set to empty values
$name = $email = $chkemail = $password = $chkpassword =$address = $towncity = $postcode = "";
//Required field validation

Answer 1

Seems there was no issue, but instead an issue with the email.php that stopped the rest of the statement being executed. Now to pick that to bits. Sometimes a few hours away from the screen is all it needs!
Thanks all that answered..

Answer 2

You shouldn't check every statement for the success
The modern programming doesn't work this way. Any statement can report an error in case one occurs. While if there was no error, then everything went all right.
So, just get rid of all conditions and send your email.
