In All in One SEO 4.2.2 we introduced a number of filter hooks that make it easier for multilingual plugin developers to integrate with our plugin.
Common uses for these filter hooks are:
- Localizing the post/term meta AIOSEO outputs in the source code
- Integrating with the multilingual sitemap capabilities of AIOSEO
- Localizing the options of AIOSEO (e.g. default title/description formats)
IMPORTANT:
This documentation is aimed at developers who know what filter hooks are and how to use them. If you simply want to know if your multilingual plugin supports AIOSEO, click here.

Localizing Post/Term Meta
One of the core functionalities of All in One SEO is outputting SEO data, social markup and JSON schema into the source code of every page.
AIOSEO stores this data in its own custom tables, aioseo_posts and aioseo_terms. As a result, this data cannot be accessed like traditional post/term meta.
Filtering Data When it is Loaded
When this data is loaded, it can be filtered using the aioseo_get_post and aioseo_get_term hooks.
The data is typically only loaded once per request and should stay consistent for the duration of the request.
Filtering Data When it is Saved
If needed, the data can also be filtered before it is saved by using the aioseo_save_post and aioseo_save_term hooks.
Please note the following:
- If a post is saved via the Block Editor, then this hook will run twice. Once when the post is saved via the REST API by the Block Editor; another time when the post is saved via a regular POST request.
- AIOSEO should automatically sanitize any of the data you’ve filtered, but we still implore you to adequately sanitize any data you manipulate on your end as well.
Integrating with the multilingual sitemap
All in One SEO is capable of generating a multilingual sitemap if you tell it what the translated versions of each post/term are. You can add dynamically add this information using our aioseo_sitemap_post and aioseo_sitemap_term hooks respectively.
