ログインしていない状態で/wp-admin/にアクセスするとurl変更したログイン画面にリダイレクトされてしまう

By Anonymous User 16694661 (anonymized_16694661) on December 12, 2018

ワードプレスのデフォルトの仕様だと思いますが、/wp-admin/にアクセスするとプラグインで変更したログイン画面のurlヘリダイレクトされてしまいますのでこちらの改善もお願いいたします。例） example.co.jp/wp-admin ↓　リダイレクト example.co.jp/プラグインで設定したログイン画面のURL文字列個人的には下記のコードで対処しています。


add_action('init', 'remove_default_redirect');
add_filter('auth_redirect_scheme', 'stop_redirect', 9999);

function stop_redirect($scheme)
{
    if ( $user_id = wp_validate_auth_cookie( '',  $scheme) ) {
        return $scheme;
    }

    global $wp_query;
    $wp_query->set_404();
    get_template_part( 404 );
    exit();
}

よろしくお願いいたします。

Great tool, simple yet powerful.

By unostar on October 29, 2017

Like the simplicity and efficiency of the plugin. One thing I would really like to change is CAPTCHA. C'mon guys, haven't you seen Google's reCAPTCHA? It's way much better, imo.

大変良いプラグインです

By Tomo (tomoygt6) on September 29, 2017

ログインページの変更するなどの機能の他、不正にログインしようとしてきた履歴を見れるなど、一通りのセキュリティを提供してくれる良いプラグインです。
