Babel question - checking for existence of translation in onHandleRequest plugin

Hello All! I'm hoping someone might be able to give me some help! I'm new to modx I'm afraid...

I'm working on an existing multi language website (modx 2.3.3 / babel 2.2.5). The separate language versions are set up in separate contexts, as I believe is usual with Babel.

There's a plugin called "Gateway" attached to the OnHandleRequest system event that is doing various things including some IP-to-geo.

But the site as a whole doesn't have translations for *every* page.

I need to check whether translations exist in the "Gateway" plugin, before (if necessary) switching context.

So... maybe I'm going about this the wrong way... but I thought I'd use runSnippet to run the BabelLinks snippet from "Gateway" and thereby work out which translations were available.

The problem is that $modx->resource is still undefined at this point so I can't pass a resourceId parameter to BabelLinks.

I've tried using findResource on $_REQUEST['q'] but I can't get this working - maybe when modx does it $_REQUEST['q'] gets cleaned up somehow?

Is there a better way to approach this?

With thanks for any help!

I don't know anything about Babel, but you can set $modx->resource yourself if you have a default page in mind and that would work for you.

$docId = 12; // ID of default page
$modx->resource =& $modx->getObject('modResource', $docId);

If the page you want is in the $_GET array, you should be able to pull it out and rewrite the code above to use it.

This might give you useful information in the MODX Error Log:

$msg = print_r($_GET, true);
$modx->log(modX::LOG_LEVEL_ERROR, $msg);

What I forgot to explain was that I don't have the resource id in the Gateway plugin because we're using friendly urls.

Rather than $_GET['q'] being the resource id (as I believe would be usual when NOT using friendly urls), $_GET['q'] is the friendly url.

This is why I was using the "findResource" method to find the resource id associated with the friendly url. But it doesn't always seem to work and I'm wondering if it's because I have to manually clean up things like the presence (or not) of trailing slashes in $_GET['q'].

Possibly. What does the code I posted above put in the error log?

Actually I think I have it working now. I'm basically doing this:

if (isset($_REQUEST['q']) && $_REQUEST['q'] != '') {
    $alias = $_REQUEST['q'];
    $resource_id = $modx->findResource($alias); 
    if (!is_numeric($resource_id)) $resource_id = $modx->findResource($alias . '/'); 
    if (is_numeric($resource_id)) {
        //got resource id so can now use BabelLinks snippet (slightly modified) to check for translations
    }
}

So if I fail to find the resource id from the alias without a trailing slash, I just slap one on the end and try again...

But thanks for your help, though, and not just here - I already recognise your name from various other modx postings!
