在我的wordpress网站上，我创建了一个自定义注册页面，使用"PHP Code"插件在wordpress中注册。现在我想在用户完成注册后自动登录。我做了很多研究，但找不到解决问题的方法。我尝试在自定义页面中测试以下示例代码片段:
<?php
//Log in a WordPress user programmatically
function auto_login( $user ) {
$username = $user;
if ( !is_user_logged_in() ) {
$user = get_user_by('login', $username );
$user_id = $user->ID;
wp_set_current_user( $user_id, $user_login );
wp_set_auth_cookie( $user_id );
do_action( 'wp_login', $user_login );
}
}
auto_login('admin');
?>
但我得到以下错误。
Warning: Cannot modify header information - headers already sent by (output started at /home/content/19/11054119/html/wp-content/plugins/sitepress-multilingual-cms/inc/language-switcher.php:921) in /home/content/19/11054119/html/wp-includes/pluggable.php on line 925

所以我想知道无论如何要做自动登录而不触及主题功能。如果你有任何想法或解决方案，请帮助我。
谢谢
您应该使用核心函数wp_signon https://codex.wordpress.org/Function_Reference/wp_signon这是示例代码
function custom_login() {
$creds = array();
$creds['user_login'] = 'example';
$creds['user_password'] = 'plaintextpw';
$creds['remember'] = true;
$user = wp_signon( $creds, false );
if ( is_wp_error($user) )
echo $user->get_error_message();
}
您可以这样尝试:
if( isset($_POST['log']) && isset($_POST['pwd']) ):
$creds = array( 'user_login' => $_POST['log'], 'user_password' => $_POST['pwd'], 'remember' => $_POST['rememberme'] );
$user = wp_signon( $creds, false );
if ( is_wp_error($user) ): echo $user->get_error_message(); endif;
wp_set_current_user($user->ID);
return $user;
endif;
你可以在这里查看更多信息
//Log in a WordPress user programmatically
function auto_login( $username ) {
if ( !is_user_logged_in() ) {
$UserData = get_user_by('login', $username );
$iUserid = $UserData->ID;
$UserLogin = $UserData->user_login;
wp_set_current_user($iUserid, $UserLogin);
wp_set_auth_cookie($iUserid);
do_action('wp_login', $UserLogin);
}
}
auto_login('admin');
