添付ページで次および前の添付画像ナビゲーションを作成する方法
'。 __( '前の画像'、 '$ text_domain') ''); ? __( '次の画像'、 '$ text_domain') ''); ?>
素晴らしい作業:)
Image.phpまたはattachment.phpファイルで previous_image_link
および next_image_link
を使用します。
<nav id="image-navigation" class="navigation image-navigation">
<div class="nav-links">
<?php previous_image_link( false, '<div class="previous-image">' . __( 'Previous Image', '$text_domain' ) . '</div>' ); ?>
<?php next_image_link( false, '<div class="next-image">' . __( 'Next Image', '$text_domain' ) . '</div>' ); ?>
</div><!-- .nav-links -->
</nav><!-- #image-navigation -->
