我很新的PHP所以请大家多多包涵。我有一个注册表单，并提交输入在该表单上的值，并将它们插入到MySQL数据库表中，但出现以下错误：的MySQL - PHP - 访问被拒绝的用户“” @“localhost”的数据库“MyProject的”
ErrorAccess denied for user''@ localhost'to数据库“MyProject的”
我已经授予所有的访问是可能的，我使用我的代码的用户，但我仍然有此错误。任何帮助表示赞赏和点将被授予！
这里是我的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;
}
}
</script>

这似乎是某处读“”作为用户名，但我不知道，但。 在此先感谢。非常感谢。
混合'mysql'和'的mysqli '是问题 – RamRaider
