私は functions.php に持っています

問題は、index.php で$settings[]
が正しくエコーされないことです。例えば
query_posts('category_name='.$settings["categoriesmain3"].'&posts_per_page=1');,
追加するvar_dump
かprint_r
、カテゴリ名をエコーする代わりに Array {} (空の配列) のようなものをエコーする場合は、
query_posts('category_name=Category3&posts_per_page=1');
はCategory3
、ユーザーがバックエンドから選択したカテゴリです。私の functions.txt はhttp://pastebin.ca/2476028
です。ワードプレスの学習に最善を尽くしているので、助けてください。
