У меня возникли серьезные проблемы с обновлением моей информации о продукте. Он извлекает всю информацию о продукте, когда я нажимаю «Редактировать», но когда я нажимаю кнопку «Отправить», чтобы обновлять сведения о продукте, это не влияет на базу данных. Я потратил довольно много времени на это и посмотрел на интернет-решения. Ни один из них не похоже на работуОбновить запрос не обновит мой список продуктов
Вот мой код:
<?php
include("functions/mysqli_connect.php");
if(isset($_GET['edit'])) {
$get_id = $_GET['edit'];
$get_pro = "select * from shop where product_id='$get_id'";
$run_pro = mysqli_query($con, $get_pro);
$row_pro=mysqli_fetch_array($run_pro);
$pro_id = $row_pro['product_id'];
$pro_name = $row_pro['name'];
$pro_cat = $row_pro['category'];
$pro_description = $row_pro['description'];
$pro_quantity = $row_pro['quantity'];
$pro_price = $row_pro['price'];
$image = $row_pro['images'];
}
?>
