pre_load_script_translations filter-hook . WP 5.0.2

Pre-filters script translations for the given file, script handle and text domain.

Returning a non-null value allows to override the default logic, effectively short-circuiting the function.

Usage

add_filter( 'pre_load_script_translations', 'filter_function_name_1869', 10, 4 );
function filter_function_name_1869( $translations, $file, $handle, $domain ){
	// filter...

	return $translations;
}

$translations(string/false)

Default: null

$file(string/false)

Path to the translation file to load. False if there isn't one.

$handle(string)

Name of the script to register a translation domain to.
