Question

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。我尝试了以下示例代码段在自定义页面中进行测试：

<?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');

?>

但我得到了以下错误。

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都要在不触及主题功能的情况下进行自动登录。如果您有任何想法或解决方案可以帮助我...

Answer 1

您应该使用核心功能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();
}

您可以尝试这种方式：

   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;

            if ( !is_user_logged_in() ) {
                $UserData = get_user_by('login', $username );
                $iUserid = $UserData->ID;
                $UserLogin = $UserData->user_login;
                wp_set_current_user($iUserid, $UserLogin);

                do_action('wp_login', $UserLogin);
            }     
        }

        auto_login('admin');
