AIXF XFMG: Require Description 2.3.7

Overview​

Adds per-category / per-album rules to require a Description when users add or edit media in XenForo Media Gallery (XFMG).

What counts as “empty”?
After stripping BBCode/HTML, decoding entities, and removing Unicode spaces (NBSP/ZWSP), the text must contain at least one visible character.

Install / Upgrade​

1. Upload AIXF_XFMG_RequireDescription_2.3.7.zip via ACP → Add-ons → Install/upgrade from archive.
2. Tools → Rebuild caches (phrases/templates).
3. Configure: ACP → AIXF XFMG: Require Description
   • Tick categories and/or (up to 200) albums where a description is mandatory.
   • Save.

How it enforces​

The add-on blocks saves with an inline/overlay error if Description is empty. It checks in multiple places:

• XFMG\Service\Media\Creator & Editor (validation)
• XFMG\Entity\MediaItem::_preSave (field error on description)
• Global entity_pre_save listener (catch-all)
• Controller returns overlay-safe errors (both field-keyed and top-level)
