My problem is I am having a cart_array which store the product added into my cart. when I press submit and process through the first block of php, if there's sufficient data, it should go to the unset($_SESSION['cart_array']); part and destroy the cart_array, however, it does not do so, the item added still show up in my cart.php. I tried session_destroy also no luck. Thing to note is that it does echo out $success which means the code should pass through that part but why it didn't unset my cart_array?
<?php
if ($_POST['cartOutput']) {
$customer_name = preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', '', $_POST['customer_name']);
$tel_num = preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', '', $_POST['tel_num']);
$customer_address = preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', '', $_POST['customer_address']);
$customer_messages = preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', '', $_POST['customer_messages']);
$error_status = false;
if (empty($customer_name)){
$error_customer_name ='<h4>Please Fill Your Name</h4>';
$error_status = true;
}
if (empty($tel_num)){
$error_tel_num='<h4>Please Fill Your Contact Number</h4>';
$error_status = true;
}
if (empty($customer_address)){
$error_customer_address='<h4>Please Fill Your Address</h4>';
$error_status = true;
}
if(!$error_status) {
include "storescripts/connect_to_mysqli.php";
$sql= 'INSERT INTO orders (customer_name,tel_num,customer_address,product_name, price, quantity, date_added,customer_messages) VALUES(?,?,?,?,?,?,NOW(),?)';
$stmt = $myConnection->prepare($sql);
$countArray = count($_POST["item_name"]);
for ($i = 0; $i < $countArray; $i++) {
$stmt->bind_param('sssssss', $customer_name,$tel_num,$customer_address, $_POST['item_name'][$i], $_POST['amount'][$i], $_POST['quantity'][$i],$customer_messages);
$stmt->execute();
}
;
$to_address="someone@gmail.com";
$subject="Online Store Order Submission";
$cartTotal=$_POST['cartTotal'];
$message="Input from online order form.
";
$message .="Name: ".$customer_name."

$message .="Tel: ".$tel_num."

mail($to_address, $subject, $message);
$success= 'ORDER SUMITTED SUCCESSFULLY! Thank you and WELCOME to shop again!';
unset($_SESSION["cart_array"]);
}
}
?>
another thing to note is when I make the form action posted to another file let's say order.php and put the above code in it, it UNSET the session, of cause i change the POST to ISSET and put exit() after the unset thou, when i try to put exit() in my cart.php it just go blank if it submitted succesffully.
any help would be appreciated
The below are all the PHP BLOCK above HTML tag for the reference.
