>我有以下代码，但我在这里被阻止了。
<?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; ?>
有人可以帮助我组合这部分代码吗？
我已经试过了，但告诉我标题已经发送了。
<?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'] = $login;
header('Location: http://www.site.ro/1/index.html');
exit();
}
}
}
?>
<?php endif; ?>
我是 php 的初学者，所以请理解我。提前谢谢你。
解决！
这是最终代码：
<?php if ($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'] = $login;
header('Location: http://www.site.ro/1/index.html');
exit();
}
}
}
endif; ?>
一旦将任何内容发送给用户，就无法修改标头。这包括任何错误的空格或换行符。
<?php if ($page == 'login'): ?>
<?php
require 'members/core/init.php';
$general->logged_in_protect();
您停止 php 执行的时间足够长，可以在第 1 行和第 2 行之间发送一个换行符。
将其更改为以下内容，然后重试。
<?php if ($page == 'login'):
require 'members/core/init.php';
$general->logged_in_protect();
代码中的某处可能有一些空格。

你可以找到它。

或者最简单的解决方案是打开输出缓冲
输出缓冲允许您做的是回显/打印您想要的任何内容，并且仍然保持将标题信息发送到页面任何位置的能力。
