Question

您好，感谢您的时间。我有一个名为get getresult.php的文件，它在mysql服务器上为登录的用户检查用户名和密码。

如果登录成功，我只是将其重定向到页面index.php。感谢您提供任何帮助。

<?php
// version 1.1
if (isset($_POST['password'])) // if the password is set then the  form has been submitted on login.php page
{
 include("config.php");
 $username =  mysql_real_escape_string($_POST['username']);
 $password = mysql_real_escape_string($_POST['password']);
 $qstr = "SELECT * from members where username ='$username' and password ='$password'";

 $result = mysql_query($qstr);
 if (mysql_num_rows($result)) echo "<font color=#008000><Center><b>**Successful Login**</b></Center></font>" 
 **//// I thought maybe this would be the section for the redirection code****
;

else echo "<font color=#ff0000><Center><b>**Failed Login**</b></Center></font>";
 mysql_close();
}
else echo "<font color=#ff8000><Center><b>**No login attempted**</b></Center></font>";

?>

Answer 1

登录检查后

执行此操作：

header("Location: newPage.php"); // replace newpage with whatever you want

<强>更新

标题 BEFORE 任何回显：

header("Location: newPage.php"); // replace newpage with whatever you want
if (mysql_num_rows($result)) echo "<font color=#008000><Center><b>**Successful Login**</b></Center></font>"

Answer 2

你必须确保之前没有回音或打印任何内容，然后你可以这样做：

header("Location: http://www.yoursite.com");

或者，如果你想在打印东西后重定向，我通常会有一个打印javascript的函数

function refresh_to( $location = 'index.php'){
    $output = '<script> window.location.href = '.$location.'; </script>';
    return $output;
}

之后再打电话。

Answer 3

标题（“位置：/ my / new / location”）;

Answer 4

header("refresh:5;url=http://google.com");
// version 1.1
if ( isset($_POST['password']) ) { // if the password is set then the form has been submitted on login.php page
    include("config.php");
    $username =  mysql_real_escape_string($_POST['username']);
    $password = mysql_real_escape_string($_POST['password']);
    $qstr = "SELECT * from members where username ='$username' and password ='$password'";

    $result = mysql_query($qstr);
    if (mysql_num_rows($result)) {
        $return = "<font color=#008000><Center><b>**Successful Login**</b></Center></font>";
    } else {
        $return = "<font color=#ff0000><Center><b>**Failed Login**</b></Center></font>";
    }
    mysql_close();
} else {
    $return "<font color=#ff8000><Center><b>**No login attempted**</b></Center></font>";
}

// Do the output    
print($return);

请记住单独的逻辑和输出，这将是您编码的好习惯。

注意我使用header，然后执行print，同时在header我放refresh 5（秒），这将为您的访问者提供阅读时间注意你给（重点是，如果你发出通知，但他们没有时间阅读它。）
