    $query_input = mysql_query($connect,"INSERT INTO    user_basic_info(username,email,password)VALUES('$username','$email','$password')");

    if($query_input){ 

        echo "done and dope";

    }
   else{


        echo "no";
    }
}

Answer 1

你的mysql_query函数中有错误

$query_input = mysql_query("INSERT INTO user_basic_info(username,email,password) VALUES('$username','$email','$password')",$connect);

请参阅http://php.net/manual/en/function.mysql-query.php

BTW请使用mysqli

mysqli_query("INSERT INTO user_basic_info(username,email,password)VALUES('$username','‌$email','$password')‌",$connect);

首先，您应该尝试使用MySQLi或PDO (tutorial here)

$connect = mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno())
{
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

if(isset($_POST['submit']))
{

    $username = $_POST['username'];
    $email = $_POST['email'];
    $password = $_POST['password'];

    $query_input = mysqli_query($connect,"INSERT INTO    user_basic_info(username,email,password)VALUES('$username','$email','$password')");

    if($query_input){ 

        echo "done and dope";

    }
    else{


        echo "no";
    }
    //close db connection
    mysqli_close($connect);
}

用户信息没有进入MYSQL db
