apply_filters( "get_{$meta_type}_metadata_by_mid", stdClass|null $value, int $meta_id )

Since
5.0.0
Short-circuits the return value when fetching a meta field by meta ID.

Description

The dynamic portion of the hook name, $meta_type, refers to the meta object type (blog, post, comment, term, user, or any other type with an associated meta table).
Returning a non-null value will effectively short-circuit the function.

Possible hook names include:

  • get_blog_metadata_by_mid
  • get_post_metadata_by_mid
  • get_comment_metadata_by_mid
  • get_term_metadata_by_mid
  • get_user_metadata_by_mid
