保存按钮不发送数据到 mysql 数据库。基本增删改查 mysql db 上的所有内容都是正确的，所有表名等 保存按钮什么也没做 感谢 4 的帮助
<?php
require("./connection.php");
if (isset($_POST['save'])) {
$stmt = $connect->prepare('INSERT INTO account (fullname,contact,address,email)
VALUES(:fullname,:contact,:address,:email)');
$stmt->bindValue('fullname', $_POST['fullname']);
$stmt->bindValue('contact', $_POST['contact']);
$stmt->bindValue('address', $_POST['address']);
$stmt->bindValue('email', $_POST['email']);
$stmt->execute();
}
