Translate ACF Fields — Lang Forge Multilingual Integration

Advanced Custom Fields is the backbone of most content-heavy WordPress sites. Landing pages, product specs, team profiles, case studies — all built with ACF field groups and ACF Pro’s repeater, flexible content, and group fields. Translating those fields correctly is one of the hardest parts of running a multilingual WordPress site, and Lang Forge is one of the few plugins that gets it right.

Full ACF Pro support

Lang Forge understands every ACF field type and how it stores its data. No “might work” compatibility — every field type is explicitly supported.

The visual editor + ACF

The Lang Forge split-screen visual editor renders ACF field groups in their native structure. Repeaters show one row at a time, with sub-fields clearly labeled. Flexible content layouts appear with their chosen layout name. Groups collapse and expand for focused work.

You never have to hunt for fields. You never have to worry about which row of a repeater you’re in. The editor shows it exactly like ACF shows it in the post edit screen.

AI translation for every ACF field

Click the AI Translate button on any individual field — text, textarea, WYSIWYG, or a sub-field inside a repeater — and it’s translated with AI. Click AI Translate All to translate every translatable field in the post, including all ACF field group data, in one pass.

Post Object and Relationship fields

When a post has a Post Object or Relationship field pointing to another post, Lang Forge resolves the reference to the correct language version at display time. If your source language page links to English Product A, the German translation of that page links to German Product A, not English Product A.

This is one of the trickiest parts of multilingual ACF integration, and it works out of the box.

Options Pages

ACF Options Pages are fully translatable. Create an options page, add translatable fields, and Lang Forge exposes them in the visual editor for each language.
