функция помещает html за пределы предполагаемых тегов span

Question

Здесь вы увидите, что у меня есть две функции, настроенные для "fb_comment_count" и "my_post_gallery": Pastebin .

Вокруг строки 123 вы увидите, что я использую "fb_comment_count».Проблема в том, что сгенерированная разметка не помещает номер счетчика комментариев в эти span теги, а скорее где-то еще.

Ниже сгенерированная разметка показывает, что я имею в виду.Все счетчики комментариев (теги a) помещаются наверх, а теги span (<span class="comment-number"></span>) пусты.Может кто-нибудь помочь мне понять, почему это происходит?

Answer 1

В вашей PHP-функции используйте return вместо echo.так, для примера вместо этого в строке 26:

echo $comments;

измените его на:

return $comments;

То же самое относится и к другим строкам с echo.
