Hi @Ibrahim50 
Try to use the function die it works with server side like that:
if(empty($_POST['name'])){ die("You need to enter your name.");
This link will help you:
When I come home I’ll try your code

A simple way to check errors again
Don’t use an array to put your errors, you can only declare variables error for each fields like that:
<?php
// define variables and set to empty values
$nameErr = $emailErr = $genderErr = $websiteErr = "";
$name = $email = $gender = $comment = $website = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (empty($_POST["name"])) {
$nameErr = "Name is required";
} else {
$name = test_input($_POST["name"]);
}
if (empty($_POST["email"])) {
$emailErr = "Email is required";
} else {
$email = test_input($_POST["email"]);
}
if (empty($_POST["website"])) {
$website = "";
} else {
$website = test_input($_POST["website"]);
}
if (empty($_POST["comment"])) {
$comment = "";
} else {
$comment = test_input($_POST["comment"]);
}
if (empty($_POST["gender"])) {
$genderErr = "Gender is required";
} else {
$gender = test_input($_POST["gender"]);
}
}
?>

ستفيدك الملاحظات التالية، خذها بعين الإعتبار.
المشكلة الأولى في كودك:
أنك قمت بعمل form لإضافة Course ولكن الفورم الـ inputs الخاصة به تحمل الأسماء التالية:
name="name"
name="Lecturer"
name="Status"
ومن ثم في عملية إضافة الكورس Insert قمت بإستخدام أسماء مختلفة:
$_POST['name']
$_POST['description']
$_POST['order'];
لهذا تحصل على تلك الأخطاء في الصورة التالية:
حقيقة أنا لم أفهم لماذا قمت بعمل ذلك الـ form بتلك الحقول التي تطلب Lecturer, Status, name ومن ثم عند إضافتها إستخدمت الأسماء التالية name, description, order ربما قمت بنسخها من صفحة أخرى قمت بالعمل عليها سابقاً ونسيت تعديل ذلك.
لهذا قم بترتيب ذلك وجعلها متطابقة بالشكل الذي يحقق هدفك
قم بمحاولة حل مشكلة إضافة الـ course أولاً من خلال الملاحظة أعلاة وأخبرني بالنتيجة.
