WP filter for thumbnails suffix

Use the ‘upload_dir’ filter to manage the path and ‘wp_unique_filename’ filter to manage the file name. Coordinate with the ‘wp_handle_upload’ filter which manages the data returned by the wp_handle_upload() function, which becomes the data stored in attachment meta data.

I solved this using the wp_get_attachment_metadata filter. Removed the suffixes -{$width}x{$height} for all sizes, and put the prefix at the beginning of the file name, instead in the beginning URL.

function attachment_metadata_filter($data) {
  foreach ($data['sizes'] as $key => $size) {
    $width = $size['width'];
    $height = $size['height'];

    $fileNoSuffix = str_replace("-{$width}x{$height}", '', $data['sizes'][$key]['file']); // remove suffix
    $data['sizes'][$key]['file'] = "{$width}x{$height}/" . $fileNoSuffix; // add prefix
  }

  return $data;
}
add_filter('wp_get_attachment_metadata', 'attachment_metadata_filter');
