Hijacking WordPress Internationalisation
As part of a new feature I am developing for the next release of my Welcome Pack plugin for BuddyPress, I needed a really smart way of dynamically adding my own translations for strings at page-load time; creating a stand-alone .mo file to load the strings wasn’t a great solution, for reasons of requiring people to know how to configure file permissions on the server, having to figure out how to write a .mo file (I wish they were as easy as XML, but they aren’t), and — honestly — doing it that way feels like such a hack.

Hey Paul,
Was meaning to reply to this the other day, but got sidetracked!
Just tried it and it does what I want it to do, except for one instance.
I’m trying to override a string that BP uses on an AJAX request (in my case, when a private message is sent, BP outputs a message).
I’ve tried overriding the string by hooking into the “init” action, but not sure if this is the correct action I should be hooking into.
Here’s the full function:
function ray_override_l10n() {
global $l10n;
$mo = new MO();
$l10n['buddypress'] = &$mo;
if ( isset( $l10n['buddypress'] ) ) {
$l10n['buddypress']->entries['There was an error sending that message, please try again']->translations[0] = 'You are not friends with the person(s) you are attempting to send a message to. Your message has not been sent.';
$l10n['buddypress']->entries['There was a problem sending that reply. Please try again.']->translations[0] = 'You are not friends with the person(s) you are attempting to send a message to. Your message has not been sent.';
}
}
add_action( 'init', 'ray_override_l10n' );
Any ideas?

For Welcome Pack’s email feature, I use the above technique and have it hooked in like so:
add_action( 'init', 'dpw_load_dynamic_i18n', 9 );Have a look dpw_load_dynamic_i18n() in Welcome Pack’s core.php. It is a bit hard to read as there’s a pair of nested FOR loops, but would suggest you use MO->add_entry() etc rather than write directly to the arrays. I think I switched to doing that after I wrote the above post.

Paul, thanks for the moment of clarity!
Of course it has to do with setting the priority for the init action! *slaps head*
Thanks also for the add_entry() tidbit, I’ll look into that!
