【问题描述】：
我对 PHP 很陌生，所以请多多包涵。我有一个注册表单，我正在提交在该表单上输入的值并将它们插入到 MySQL 数据库表中，但我收到以下错误：
用户 ''@'localhost' 对数据库 'myproject' 的错误访问被拒绝
我已向我在代码中使用的用户授予所有可能的访问权限，但我仍然遇到此错误。任何帮助表示赞赏，并将获得积分！
这是我的 HTML 表单：
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="stylesheet.css">
<title>Registration Page</title>
<script>
function validateForm() {
var x = document.forms["myForm"]["netID"].value;
if (x == null || x == "") {
alert("NetID must be filled out");
return false;
}
var y = document.forms["myForm"]["email"].value;
if (y == null || y == "") {
alert("Email must be filled out");
return false;
}
var n = document.forms["myForm"]["fname"].value;
if (n == null || n == "") {
alert("First Name cannot be blank");
return false;
} else if (n.length < 2) {
alert("First name cannot be less than 2 characters!");
return false;
}
var b = document.forms["myForm"]["lname"].value;
if (b == null || b == "") {
alert("Last Name cannot be blank");
return false;
} else if (b.length < 2) {
alert("Last Name cannot b less than 2 characters!");
return false;
}
}

它似乎在某处将 '' 作为用户名读取，但我不确定。 提前致谢。非常感谢。

混合
mysql和mysqli是个问题 -
谢谢。您对如何解决此问题有什么建议？
