url 重定向的用户名

Question

我安装了一个基本系统 table 应该读取用户名和 url 但我是一个完全的菜鸟 PHP 这就是我得到的，如果有人可以帮助我，这样当输入用户名时，它会自动将他们重定向到与该帐户关联的 url 谢谢。

 <?php 
$host="localhost"; // Host name 
$username="root"; // Mysql username 
$password="root"; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="redirect"; // Table name 

// Connect to server and select databse. 
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB"); 

// username and password sent from form 
$myusername=$_POST['myusername']; 

// To protect MySQL injection (more detail about MySQL injection) 
$myusername = stripslashes($myusername); 

$myusername = mysql_real_escape_string($myusername); 
$sql="SELECT * FROM $tbl_name WHERE username='$myusername'"; 
$result=mysql_query($sql); 

// Mysql_num_row is counting table row 
$count=mysql_num_rows($result); 
// If result matched $myusername and $mypassword, table row must be 1 row 
if($count==1){ 
// Register $myusername, $mypassword and redirect to file"login_success.php" 
$_SESSION['username'] = $myusername;  
$result = mysql_query("SELECT redirect FROM members"); 

while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { 
   header("Location: " . $row['redirect']); 
} 
exit(); 
} 
else { 
echo "Wrong Username or Password"; 
} 
?>

编辑： 快速更新基本上这有一个文本输入框，当填入正确的密码短语时，它会将您重定向到一个外部 url，它与数据库中的名称一起保存。我不知道如何获得它，以便如果有人有关于此 ID 的教程喜欢它，则重定向从文本框正确发生

Answer 1

if(isset($_SESSION['username'])){
    header("location: http://yoururl/" .$_SESSION['username']);
}

 <?php
    if($_POST){

        $host="localhost"; // Host name 
        $username="root"; // Mysql username 
        $password="root"; // Mysql password 
        $db_name="test"; // Database name 
        $tbl_name="redirect"; // Table name 

        // Connect to server and select databse. 
        $con = mysqli_connect($host, $username, $password, $db_name);

        // username sent from the form 
        $myusername = $_POST['myusername']; 
        // To protect MySQL injection (more detail about MySQL injection) 
        $myusername = stripslashes($myusername); 
        $sql = "SELECT * FROM redirect WHERE username='$myusername' LIMIT 1"; 

        $result = mysqli_query($con, $sql);
        // Mysqli_num_row is counting table row 
        $count = mysqli_num_rows($result);
        // If result matched $myusername, table row must be 1 row 
        if($count === 1){
            $_SESSION['username'] = $myusername; 
            $row = mysqli_fetch_array($result, MYSQLI_ASSOC);   
            //redirect to file url from database
            header("Location: " . $row['url']); 
        }else{
            echo 'Invalid Username';
        }
    }else{
?>  

    <html lang="en">
    <head>
        <title>My App</title>
    </head>
    <body>
        <form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post">
            <input type="text" name="myusername"/>
            <input type="submit" value="submit"/>
        </form>
    </body>
    </html>
<?php } ?>

这应该可以解决...

用你的替换这个。

$result = mysql_query("SELECT redirect FROM members where username = '.$myusername.'");

url 重定向的用户名

Username to url redirect
