pre_get_language_files_from_path │ filter-hook │ WP 6.5.0

Filters the translation files retrieved from a specified path before the actual lookup.

Returning a non-null value from the filter will effectively short-circuit the MO files lookup, returning that value instead.

This can be useful in situations where the directory contains a large number of files and the default glob() function becomes expensive in terms of performance.

Usage

add_filter( 'pre_get_language_files_from_path', 'wp_kama_pre_get_language_files_from_path_filter', 10, 2 );
