The filter name is gettext
, and you would add it like this:
add_filter( 'gettext', 'my_wp_text_email_filtering', 10, 3 );
function my_wp_text_email_filtering( $translated, $text, $domain ) {
return FilterTextOfEmail( $translated );
}
The $text argument is there also in case you want to access the pre-translated text.
