我不知道如何更新我的上次登录时间 [英] I can't figure out how to update my last inlog time

问题描述

我正在尝试为网站提供最后一个活动功能.但我无法使它正常工作.我希望你们能在这里帮助我.

I'm trying to make an last activity function for an website. but i can't get it to work. I hope you guys can help me out here.

这是我的查询:

$last_activity_query = "UPDATE users_table SET user_name  = '$user_name' WHERE 'date_last_inlog' = NOW()";

$result_update =  mysql_query($last_activity_query);

$last_activity_update = mysql_fetch_array($result_update);

这是我的数据库表的打印屏幕:

this is an print screen of my database table:

我想将此更新存储在最后一行.

I want to store this update in the last row.

提前谢谢！

我现在已经更改了脚本，但是它仍然没有更改数据库表中的任何内容.

i've changed my script now but its still not changing anything in my database table.

这是更改:

if (isset($_REQUEST['inlog_submit'])){//checks if form is submitted


                    $user_name = $_REQUEST['username_input'];//request username from inlog_form
                    $password = $crypt;//gets enqrypted pass
                    //$tbl_name="user_table"; // Table name
                    $query = "SELECT * FROM users_table WHERE user_name= '$user_name' AND password='$password'";//query stored in var
                    $last_activity_query = "UPDATE users_table SET 'date_last_inlog' = NOW() WHERE user_name  = '$user_name'";
                    $result = mysql_query($query);//var with result of query
                    $result_update =  mysql_query($last_activity_query);

                    if ($user_name = mysql_fetch_array($result)){//checks inlog data from form with the $result query
                        $_SESSION['user_name'] = $user_name[user_name];//creates session with username
                        $_SESSION['password'] = $password[password];//creates session with password
                        $last_activity_update = mysql_fetch_array($result_update);
                        header ('Location: admin.php');//when login is correct redirect to specified page
                    }else{
                        $error_inlog = 10;//when inlog data is incorrect this error will show
                    }
                }
            ?>

推荐答案

您的SQL查询顺序错误.

Your SQL query is in the wrong order.

$last_activity_query = "UPDATE users_table SET 'date_last_inlog' = NOW() WHERE user_name  = '$user_name'";
