WP_Metadata_Lazyloader::lazyload_comment_meta() WordPress Method
The WP_Metadata_Lazyloader::lazyload_comment_meta() method is used to lazy load comment meta data for a given comment ID. This is useful when comment meta data is not needed immediately, but can be loaded later when needed. This can help improve performance by avoiding unnecessary database queries.
WP_Metadata_Lazyloader::lazyload_comment_meta( mixed $check ) #
Lazy-loads comment meta for queued comments.
Description
This method is public so that it can be used as a filter callback. As a rule, there is no need to invoke it directly, from either inside or outside the WP_Query object.
Parameters
- $check
(mixed)(Required)The
$checkparam passed from the 'get_comment_metadata' hook.
Return
