Question

所以我正在尝试创建一个HTML / PHP代码，要求您订购糖果棒（火星，士力架，银河系），然后列出订单的收据，成本，总成本等等。我做了所有这些，现在我想将所有值存储到MySQL数据库中，当点击订单时我想列出从数据库中生成的每个订单。我正在努力，但无法理解。它立刻给我错误，它无法连接到MySQL数据库，我使用WAMP localhost，我创建了数据库和用户和所有权限，尝试了一百次，但没有。不知道我做错了什么。

错误如下：

警告：mysqli_connect（）：在第34行的C：\ wamp \ www \ MAKEUP2 \ Q1 \ order.php中调用堆栈＃时间内存函数位置1 0.0010 143072 {main}（）.. \ order.php：0 2 0.0010 144488 mysqli_connect（）.. \ order.php：34连接失败：Accèsrefusépourl'utilisateur：'revetinja'@'@ localhost'（mot de passe：OUI）

这就是我到目前为止所做的......

将输入表单中的值存储在MySQL中并输出它们，但无法连接到MySQL
