pre_user_id filter-hook . WP 1.5.0
Filters the comment author's user ID before it is set.
The first time this filter is evaluated, 'user_ID' is checked (for back-compat), followed by the standard 'user_id' value.
Usage
add_filter( 'pre_user_id', 'filter_function_name_2510' ); function filter_function_name_2510( $user_ID ){ // filter... return $user_ID; }
- $user_ID(int)
- The comment author's user ID.
