使用这两个功能,这些将有很大帮助:这两个都经过测试

要将文件名添加到标题和标题,请使用下面的代码
/**
* Add the Media/Image filename to caption, Title
*
*/
function wpsx_5505_modify_uploaded_file_meta($meta, $file, $sourceImageType) {
// Get the parent post ID, if there is one

} else {

}
// Only do this if we got the post ID--otherwise they're probably in
// the media section rather than uploading an image from a post.
if($post_id && is_numeric($post_id)) {
// Get the post title
$post_title = get_the_title($post_id);
// If we found a title
if($post_title) {
$meta['title'] = $post_title;
$meta['caption'] = $post_title;
}
}
return $meta;
}
