WordPress：按帖子格式显示占位符文本

Question

如果帖子的帖子格式为“画廊”，我想在“内容编辑器”中生成占位符文本。但我无法让它工作：

functions.php：

add_filter( 'default_content', 'wpse57907_default_content', 10, 2 );
function wpse57907_default_content( $content, $post ) {
    if ( 'post' == $post->post_type && has_post_format('gallery')) {
        $content = '<i style="color:#999">Use this area to upload and edit images... any text put in here will NOT be generated on the project&apos;s page. Please use the fields above for text.</i>';

    return $content;
    }
}

Answer 1

应该这样做：

add_filter( 'default_content', 'wpse57907_default_content', 10, 2 );
function wpse57907_default_content( $content, $post ) {
    $format = get_post_format($post->ID);
    if ( 'post' == $post->post_type && $format == 'gallery') {
        $content = '<i style="color:#999">Use this area to upload and edit images... any text put in here will NOT be generated on the project&apos;s page. Please use the fields above for text.</i>';
    }
    return $content;    
}

另外，请确保您的主题已设置为通过 add_theme_support 实际支持帖子格式，并且您的帖子具有正确的帖子格式（图库）。
