Description
The “fun_load_textdomain” filter is used to modify the path to the translation file. View load_plugin_textdomain for more details.
A plugin (or theme) can modify the path with the code:
<?php add_filter( 'fun_load_textdomain', 'filter_function_name' ); ?>
The hook is located in the file-un-attach/file-unattach.php file.
Example
// Apply filter
function modify_fun_load_textdomain $path ) {
return "path/to/custom/translation/file/";
}
add_filter('fun_load_textdomain', 'modify_fun_load_textdomain');
Note: $path is an string, path relative to the translation .mo file.
