我使用的代码调用了上传到帖子中的所有附件。我添加了图库自定义帖子类型，但没有显示任何内容。

但这在我的“漂亮的小骗子”帖子类型上有所体现。我做错了什么。

   <?php

if ( \'pretty-little-liars\',\'gallery\' == get_post_type() ) { //condition to show     gallery on post type - gallery

if ( $attachments = get_children( array(
    \'post_type\' => \'attachment\',
    \'post_mime_type\'=>\'image\',   //return all image attachment only
    \'numberposts\' => -1,   //get all the attachments
    \'post_parent\' => $post->ID
)));

foreach ($attachments as $attachment) {
    // you can customize the oputput
    echo \'<li><p class="alignleft">\';
    echo \'\'.wp_get_attachment_link( $attachment->ID,\'full\' , false, false );
    echo \'</p>\';
    echo \'\'.$attachment->post_excerpt.\'<br><br>\';
    echo \'<p class="alignright"><h5>\'.$attachment->post_title. \'</h5>\';
    echo \'\'.$attachment->post_content.\'\';
    echo \'</p></li>\';
}
}

?>
