Add WordPress function content to filename

I’m going to add this to readme as I think it can help other users. It’s easy.

First you have to create a custom rule in the filename structure option using curly braces, like {my_custom_rule}. You just have to write it, in any position you want

Now you can use the filter frou_sanitize_file_name to create a custom function. In your case, as you want to put the user id it would be something like this:

add_filter( 'frou_sanitize_file_name', function($filename_infs){
	$filename_infs['structure']['translation']['my_custom_rule'] = get_current_user_id();
	return $filename_infs;
}, 20 );

You’re welcome. 🙂
No, you don’t need to redo. Your rule will be there on next update.

You can put that in your functions.php for example
