Php 数据未插入数据库游戏重新注册

因此，我正在制作一个网络游戏应用程序。我的问题是我的

注册表。php

没有在数据库中插入用户。请需要帮助，顺便说一句，我只是一个php初学者谢谢

代码如下：

<?php
    require_once('mysql_conn.php');
    $Username = mysql_real_escape_string($_POST['Username']);
    $Password = md5(mysql_real_escape_string($_POST['Password']));
    $Email = mysql_real_escape_string($_POST['Email']);

    $query_check ="SELECT user_name FROM account_info WHERE user_name = '$Username'";
    $retval_check = mysql_query( $query_check, $conn );

    if( $Username == "" || $Password == "" || $Email == "" ){
        echo"Please fill the field";
    } else{
        if(mysql_num_rows($retval_check)){
            echo"Username Already Taken";
        } else {
            $query = "INSERT INTO account_info(user_name,user_passemail) VALUES ('$Username','$Password','$Email');";
            $retval = mysql_query( $query, $conn );

            echo "<script>";
            echo "alert('Thank you for registering Enjoy the game !')";        
            echo "</script>";

            echo "<script>";
            echo 'location.href = "menu.html";';
            echo "</script>";
        }
    }

     mysql_close($conn);

?>

更改：

$query = "INSERT INTO account_info(user_name,user_passemail) VALUES ('$Username','$Password','$Email');";

致：

你忘了加逗号“，”错了

  $query = "INSERT INTO account_info(user_name,user_passemail) VALUES ('$Username','$Password','$Email');";

正确的

  $query = "INSERT INTO account_info(user_name,user_pass,email) VALUES ('$Username','$Password','$Email')";

警告mysql\u查询、mysql\u获取\u数组、mysql\u连接等。。扩展在PHP5.5.0中被弃用，在PHP7.0.0中被删除。 相反，应该使用MySQLi或PDO_MySQL扩展

您错过了用户名中的用户密码和电子邮件之间的错误

$query = "INSERT INTO account_info(user_name,user_pass,email) VALUES ('$Username','$Password','$Email');";

试试mysqli

            //db connection

             global $conn;

                $servername = "localhost";  //host name

                $username = "username"; //username

                $password = "password"; //password

                $mysql_database = "dbname"; //database name

            //mysqli prepared statement 

                $conn = mysqli_connect($servername, $username, $password) or die("Connection failed: " . mysqli_connect_error());

               mysqli_select_db($conn,$mysql_database) or die("Opps some thing went wrong");


        //require_once('mysql_conn.php');

        $Username = mysqli_real_escape_string($_POST['Username']);
        $Password = md5(mysqli_real_escape_string($_POST['Password']));
        $Email = mysqli_real_escape_string($_POST['Email']);

        //$query_check ="SELECT user_name FROM account_info WHERE user_name = '$Username'";
       // $retval_check = mysqli_query( $query_check, $conn );

       if(!empty($Username))
       {


            $stmt = $conn->prepare("SELECT user_name FROM account_info WHERE user_name =? ");

                            $stmt->bind_param('s',$Username);

                            The argument may be one of four types:

                            i - integer
                            d - double
                            s - string
                            b - BLOB
                            //change it by respectively 

                            $stmt->execute();

                            $get_result =$stmt->get_result();

                            $row_count= $get_result->num_rows;

                            //$row_count= $stmt->affected_rows;

                            $stmt->close();
                             //$conn->close();




       }                     

        if( $Username == "" || $Password == "" || $Email == "" ){
            echo"Please fill the field";

您有任何错误吗？

mysql\uuu

函数已被弃用-避免痛苦，将代码升级到$query上的

mysqli

或

pdo

您正在数据库上传递3个值，但您只选择了两列。您需要在用户密码、电子邮件之间添加逗号。这在您的查询中丢失，请搜索mysqli或pdo谢谢您的回答
