Tagging all assets in a sub directory

Question

I'm building a project with a lot of photo assets organized into sub directories of the main photos asset source. I'm trying to add tags to these assets so they are searchable when I try to use them in my entries.

With native features of Craft, this process seems to be very manual, I just have to click on each of these asset files and add the tags that I want.

Is there a way, either using a plugin or make a MySQL query, to bulk add tags to all the asset files under a certain sub directory?

Answer 1

Seems doable with a custom plugin.

The pseudo-code would be something like:

1. Use AssetsService to grab all of the files for the source.
2. Loop through the files and parse the parent folder paths.
3. Based on the subfolder for the asset, check if an existing tag already exists with the TagsService.
4. If 3 is true, assign that tag's value to a tag field on the Asset.
5. If 3 is false, create the tag using the TagsService, then assign that tag's value to a tag field on the Asset.
