Push items to PHP array using a form

one text

Solution:

I tried to implement the same using sessions, that works fine for me,

if (isset($_POST['insertProduct'])) {
$inserted_code = $_POST['code'];
$inserted_products = array("Entry 1", "Entry 2");
if (isset($_SESSION['myArray'])) {
    $inserted_products = $_SESSION['myArray'];
    array_push($inserted_products, "Entry $inserted_code");
    $_SESSION['myArray'] = $inserted_products;
} else {
    array_push($inserted_products, "Entry $inserted_code");
    $_SESSION['myArray'] = $inserted_products;
}
}
