私のテーマのfunctions.phpからプラグインの機能を変更するにはどうしたらいいですか？

Question

以下のコードは、 "All in One SEO"パックのプラグインです。私のテーマの404ページのタイトルを変更します。私は、この特定のプラグインがどのように機能するのかを理解しています。この例では、私のテーマの404投稿タイトルのオンボード管理と矛盾しています。

私のfunctions.phpファイルから、以下のコードでis_404（）コードの分岐をどのように掘り下げて無効にすることができますか？

class All_in_One_SEO_Pack {

    global $aioseop_options;

     return $header; 
    } 

    $post = $wp_query->get_queried_object(); 

    // the_search_query() is not suitable, it cannot just return 
    global $s; 

    global $STagging;

テンプレートタグは、非テンプレートファイルで作業している場合、私は知らないが、彼らは、あなたがプラグインのコードを変更する気にしないならば、あなたが作成することにより、プラグインのコードのあなたの迎撃を試みることができますし、あなた自身のアクションフックを追加する。

これは、カスタムコードが独自のプラグインまたはfunctions.phpに配置されていることを除いて、プラグインコードを修正することとほぼ同じです。

カスタムアクションフックに慣れていない場合は、ここでの処理を説明記事です：http://archive.extralogical.net/2007/06/wphooks/
