4.5 Validating Uploads
In this final lesson on developing our plugin, we implement the following:
- When users attempt to upload a non-MP3 file, the file is rejected.
- If an error message is displayed, we make sure it’s themed natively with the dashboard.
- When there’s an invalid file, we won’t display the link on the single post page.
Once that's all done, we'll review all of the source code for our plugin.
