Question

我有以下代码，但我在这里被阻止..

<?php
require 'members/core/init.php';
$general->logged_in_protect();

if (empty($_POST) === false) {

$username = trim($_POST['username']);
$password = trim($_POST['password']);

if (empty($username) === true || empty($password) === true) {
    $errors[] = 'Sorry, but we need your username and password.';
} else if ($users->user_exists($username) === false) {
    $errors[] = 'Sorry that username doesn\'t exists.';
} else if ($users->email_confirmed($username) === false) {
    $errors[] = 'Sorry, but you need to activate your account. 
                 Please check your email.';
} else {
    if (strlen($password) > 18) {
        $errors[] = 'The password should be less than 18 characters, without spacing.';
    }
    $login = $users->login($username, $password);
    if ($login === false) {
        $errors[] = 'Sorry, that username/password is invalid';
    }else {
        session_regenerate_id(true);// destroying the old session id and creating a new one
        $_SESSION['id'] =  $login;
        header('Location: http://www.site.ro/1/index.html');
        exit();
    }
}
} 
?>

以及以下内容：

<?php if ($page == 'login'): ?>
<?php endif; ?>

有人可以帮我组合这部分代码吗？

我已经尝试过，但告诉我标题已发送..

<?php if ($page == 'login'): ?>
<?php
require 'members/core/init.php';
$general->logged_in_protect();

if (empty($_POST) === false) {

$username = trim($_POST['username']);
$password = trim($_POST['password']);

if (empty($username) === true || empty($password) === true) {
    $errors[] = 'Sorry, but we need your username and password.';
} else if ($users->user_exists($username) === false) {
    $errors[] = 'Sorry that username doesn\'t exists.';
} else if ($users->email_confirmed($username) === false) {
    $errors[] = 'Sorry, but you need to activate your account. 
                 Please check your email.';
} else {
    if (strlen($password) > 18) {
        $errors[] = 'The password should be less than 18 characters, without spacing.';
    }
    $login = $users->login($username, $password);
    if ($login === false) {
        $errors[] = 'Sorry, that username/password is invalid';
    }else {
        session_regenerate_id(true);// destroying the old session id and creating a new one
        $_SESSION['id'] =  $login;
        header('Location: http://www.site.ro/1/index.html');
        exit();
    }
}
} 
?>
<?php endif; ?>

我是php的初学者，所以请理解我。提前谢谢。

已解决！

这是最终的代码：

<?php if ($page == 'login'):
require 'members/core/init.php';
$general->logged_in_protect();

if (empty($_POST) === false) {

$username = trim($_POST['username']);
$password = trim($_POST['password']);

if (empty($username) === true || empty($password) === true) {
    $errors[] = 'Sorry, but we need your username and password.';
} else if ($users->user_exists($username) === false) {
    $errors[] = 'Sorry that username doesn\'t exists.';
} else if ($users->email_confirmed($username) === false) {
    $errors[] = 'Sorry, but you need to activate your account. 
                 Please check your email.';
} else {
    if (strlen($password) > 18) {
        $errors[] = 'The password should be less than 18 characters, without spacing.';
    }
    $login = $users->login($username, $password);
    if ($login === false) {
        $errors[] = 'Sorry, that username/password is invalid';
    }else {
        session_regenerate_id(true);// destroying the old session id and creating a new one
        $_SESSION['id'] =  $login;
        header('Location: http://www.site.ro/1/index.html');
        exit();
    }
}
} 
endif; ?>

Answer 1

将任何内容发送给用户后，您无法修改标头。这包括任何错误的空格或换行符。

<?php if ($page == 'login'): ?>
<?php
require 'members/core/init.php';
$general->logged_in_protect();

你停止执行php的时间足以在第1行和第2行之间发送一个换行符。

将此更改为以下内容并重试。

<?php if ($page == 'login'):

require 'members/core/init.php';
$general->logged_in_protect();

Answer 2

您的代码中可能有某些空格。

你可以找到它。
或者最简单的解决方法是启用output buffering

您可以使用什么输出缓冲来回显/打印您想要的任何内容，并且仍然能够在页面的任何位置发送标题信息。
