我知道这项任务已经有了一些可用的功能，但它们似乎都没有按需要工作。
在我看来，最好的方法是在wp_handle_upload_prefilter 喜欢kaiser 他在吗this example. 不幸的是，只有当帖子已经保存到数据库中时，文件才能获取父帖子标题。
另一种方法是在add_attachment 喜欢Ijaas 做here. 然后该文件获取父帖子标题作为名称，但不会创建缩略图。以及我尝试使用wp_generate_attachment_metadata(); 创建丢失的图像大小，以无休止的循环结束（可能是因为我使用它的方式不对，但现在我有点害怕这个函数）。
如果有办法把头衔传给wp_handle_upload_prefilter 即使帖子还没有保存。
哦，顺便说一下，这是我的无穷函数，也许有人能告诉我它有什么问题。DON\'T USE THIS FUNCTION !!!
add_action(\'add_attachment\', \'fkp_rename_attacment\');
function fkp_rename_attacment($post_ID){
$post = get_post($post_ID);
$file = get_attached_file($post_ID);
$path = pathinfo($file);
$parent = get_post($post->post_parent);
$p_author = get_the_author_meta( \'display_name\', $parent->post_author );
$p_author_san = sanitize_title($p_author);
$newfilename = $parent->post_name . \'-\' . $p_author_san . \'-\' . $post_ID;
$newfile = $path[\'dirname\']."/".$newfilename.".".$path[\'extension\'];
rename($file, $newfile);
$wp_filetype = wp_check_filetype(basename($newfile), null );
$wp_upload_dir = wp_upload_dir();
$attachment = array(
\'guid\' => $wp_upload_dir[\'url\'] . \'/\' . basename( $newfile ),
\'post_mime_type\' => $wp_filetype[\'type\'],
\'post_title\' => preg_replace(\'/\\.[^.]+$/\', \'\', basename($newfile)),

$attach_id = wp_insert_attachment( $attachment, $newfile, $parent->ID );
require_once(ABSPATH . \'wp-admin/includes/image.php\');
$attach_data = wp_generate_attachment_metadata( $attach_id, $newfile );
wp_update_attachment_metadata( $attach_id, $attach_data );
}
DON\'T USE THIS FUNCTION !!!
最合适的回答,由SO网友:schwarzgrau 整理而成
尝试将函数添加到publish_post 创建了很多不必要的文件kaisers function 满足我的需要。
function modify_uploaded_file_names( $image ) {
// Use part of the post or user object to rename the image
get_currentuserinfo();
global $post, $current_user;
// 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 ( isset( $_REQUEST[\'post_id\'] ) ) {
// get the ID
$post_id = absint( $_REQUEST[\'post_id\'] );
// get the post OBJECT
$post_obj = get_post( $post_id );
// get the post slug
$post_slug = sanitize_title($post_obj->post_title);
// get the author
$author = sanitize_title( get_the_author_meta( \'display_name\', $post_obj->post_author ) );
switch( $image[\'type\'] ) {
case \'image/jpeg\' :
$suffix = \'jpg\';
break;
case \'image/png\' :
$suffix = \'png\';
break;
case \'image/gif\' :
$suffix = \'gif\';
break;
}
// if we found a slug
if ( $post_slug )
$image[\'name\'] = "{$author}-{$post_slug}-{$random_number}.{$suffix}";
}
else {
$image_name = str_place( \' \', \'-\', strtolower( $current_user->data->user_nicename ) );
$image[\'name\'] = $image_name . \'-\' . $file[\'name\'];
}
return $image;
}
// Only one arg, so 4th attr not needed - Priority set to later 20
add_filter( \'wp_handle_upload_prefilter\', \'my_modify_uploaded_file_names\', 20 );
只有一些小的变化
已替换$post_obj->post_name 具有sanitize_title($post_obj->post_title) 因为post\\u name只在我的测试中存在，而post已经保存wp_handle_upload 使用wp_unique_filename() 无论如何
