Fix Media MIME Types (CLI only)

Fixes incorrect MIME types in the Media Library using WP-CLI.

Description

Fix Media MIME Types (CLI only) is a lightweight and efficient plugin that identifies and corrects any incorrect MIME types in your WordPress Media Library.

Key Features:

• Scans your entire Media Library for potential MIME discrepancies.
• Uses PHP's FileInfo to detect the correct MIME type of media files.
• Updates the WordPress database only when a mismatch is found, ensuring minimal overhead.
• Designed solely for command-line usage (WP-CLI), with no impact on normal site visitors or admins.

This plugin is not visible in the standard WordPress interface (it is WP-CLI only). To use it, you must have WP-CLI installed on your server or local environment.

WP-CLI

You can use the following WP-CLI commands:

• wp fix-mime run

That will show something like:

Found 3 attachments. Starting the process...
Warning: Attachment ID 1: file does not exist on disk. Skipping...
