我已经创建了登录页面模板，并通过wp admin->页面创建了登录页面。在这里，我选择“登录”模板
如果有人没有登录，现在我需要重定向此页面上的用户。wp admin登录和此登录页是分开的。是否有人登录wp admin没有关系。
我使用的代码如下所示，FireFox将我重定向到错误页面，并说“页面没有正确重定向”。
if ( !is_admin() ) {
if(!isset($_COOKIE[\'login_token\']) || $_COOKIE[\'login_token\']==\'\') {
//echo $_COOKIE[\'login_token\']."KKKKKKKRRRRRRRR";
$login_page = home_url(\'/login/\');
// Two things happen here, we make sure we are on the login page
// and we also make sure that the request isn\'t coming from a form
// this ensures that our scripts & users can still log in and out.
//if( $page_viewed == "wp-login.php" && $_SERVER[\'REQUEST_METHOD\'] == \'GET\') {
// And away they go...
wp_redirect($login_page);
exit();
}
$username=$_POST[\'log\'];
$password=$_POST[\'pwd\'];
echo $_COOKIE[\'login_token\'];
// try to log into the external service or database with username and password
//$ext_auth = try2AuthenticateExternalService($username,$password);
//echo "<pre>"; print_r($ext_auth); echo \'</pre>\';
// if external authentication was successful
$ext_auth[0] = \'success\';
if($ext_auth[0]==\'success\') {
// find a way to get the user id
$uname = explode(\'@\',$username);
$user_id = username_exists($uname[0]);
// userdata will contain all information about the user
//$userdata = get_userdata($user_id);
//$user = wp_set_current_user($user_id,$username);
// this will actually make the user authenticated as soon as the cookie is in the browser
//wp_set_auth_cookie($user_id);
$path = parse_url(get_option(\'siteurl\'), PHP_URL_PATH);
$host = parse_url(get_option(\'siteurl\'), PHP_URL_HOST);
//$expiry = strtotime(\'+1 month\');
$expiry = time() + (60 * 1);
setcookie(\'login_token\', $ext_auth[0], $expiry, $path, $host);
// the wp_login action is used by a lot of plugins, just decide if you need it
do_action(\'wp_login\',$userdata->ID);
//determine WordPress user account to impersonate
// you can redirect the authenticated user to the "logged-in-page", define(\'MY_PROFILE_PAGE\',1); f.e. first
//header("Location:http://executiveboard/audit-blog");
return \'success\';

如果用户未登录，即使用户已经在登录页面中，代码也会重定向到登录页面，因此最终会出现无限重定向循环。
您应该检查用户是否已登录以及他/她所在的页面，如果他/她未登录以及他/她不在登录页面中，则应重定向。将此代码添加到函数。php：
<?php
add_action( \'template_redirect\', \'wpse_redirect_to_login_page\' );
function wpse_redirect_to_login_page() {
//You can use also is_page() function to check for specific page instead for a page template
if( !is_page_template("login-template.php") && ! is_user_logged_in() ) {
wp_redirect( get_permalink( ID_of_login_page ); );
exit();
}
}
?>
此外，您应该将登录/身份验证过程从模板文件中删除。Ore，最好用
wp_login_form 在模板文件中。看见
