我想更新我的SQL数据库，但表单中没有空值。那就是我所拥有的：if(isset($_POST['account_details_submit'])) {

$user_id = array_values($_SESSION['user_info'])[9];

$edited = date('d.m.Y h:i a');

if(isset($_POST['account_details_first_name']) and !empty($_POST['account_details_first_name'])) { $add .= " and `first_name` = '$_POST[account_details_first_name]'"; }

if(isset($_POST['account_details_last_name']) and !empty($_POST['account_details_last_name'])) { $add .= " and `last_name` = '$_POST[account_details_last_name]'"; }

if(isset($_POST['account_details_phone_number']) and !empty($_POST['account_details_phone_number'])) { $add .= " and `phone_number` = '$_POST[account_details_phone_number]'"; }

if(isset($_POST['account_details_address_1']) and !empty($_POST['account_details_address_1'])) { $add .= " and `address_1` = '$_POST[account_details_address_1]'"; }

if(isset($_POST['account_details_address_2']) and !empty($_POST['account_details_address_2'])) { $add .= " and `address_2` = '$_POST[account_details_address_2]'"; }

if(isset($_POST['account_details_city']) and !empty($_POST['account_details_city'])) { $add .= " and `city` = '$_POST[account_details_city]'"; }

if(isset($_POST['account_details_post_code']) and !empty($_POST['account_details_post_code'])) { $add .= " and `post_code` = '$_POST[account_details_post_code]'"; }

if(isset($_POST['account_details_country']) and !empty($_POST['account_details_country'])) { $add .= " and `country` = '$_POST[account_details_country]'"; }

$update = "UPDATE `users` SET `edited` = '$edited'".$add." WHERE `id` = '$user_id'";

if ($conn->query($update) === TRUE) {

echo "Record updated successfully";

} else {

echo "Error updating record: " . $conn->error;

}

}

消息为“记录已成功更新”，但只有一行正在更新的行称为“ [[已编辑”，并且该行始终更新为0我愿意以其他方式做到这一点。

P.S，我尝试使用数组值来执行此操作，但结果不是我想要的]]

我想更新我的SQL数据库，但表单中没有空值。这就是我得到的：if(isset($ _ POST ['account_details_submit'])){$ user_id = array_values($ _ SESSION ['user_info'])[9]; $ edited = ...
