Using a Template Varible to modify output of custom Object Field

Is it possible to use a Template Variable as a helper for rendering output of a custom Object's field value?
I have a select drop-down TV with the name order_status with the following input options:

Waiting for Payment==WAITING||Payment Received==PAYMENT_RECEIVED||Shipped=SHIPPED

Then i have an Order custom Object where i can do something like this:


$order = $modx->getObject('customOrder',33);
$status = $order->get('order_status');


// Here's where i need to call the template variable template
// to help me render "Waiting for Payment" instead of the original field value "WAITING"

$renderedStatus = "?????"

$ouput .= $renderedStatus

Remember i'm using a custom object here and the normal getTVValue will not help as i'm not using modResource as the source of the data.
Any suggestions?
Regards,

Pablo. [ed. note: lithiumlab last edited this post 12 years, 7 months ago.]

If this orderObject is associated with the current resource, or if it is associated with a known resource, then you can just get the value of the TV for that resource.

Thanks for the reply.
I've already checked the docs, and the examples are related to modResource

Order objects in my case are not related to modResource.
I'm using a MIGXdb / custom package to render the update form in the backend. (See screenshot attached)
A helper Single Select type TV called order_status renders the input options in the dropdown.

Now i want an easy, reusable way to render the friendly value in the frontend using the helper TV.
Its applicable to many other uses cases i think.

Is it possible to process a value trough the template variable without sending a modResource reference?
Tha same way i'm using a helper TV to render input options i want it to help render output in the frontend.
Maybe i'm missing something obvious

Where is the TV value coming from? Is it a default value when you create the TV, or is the value coming from a resource - for example, if a product is a resource.

what are the input-option-values of that TV?

[Edit]
sorry, didn't read the whole thread.

found it

Waiting for Payment==WAITING||Payment Received==PAYMENT_RECEIVED||Shipped=SHIPPED

ok, hardcoded, then its easy to get them, will post the solution later today

Not using resources. This is a custom Object to be manipulated with a migxdb form.
I'm using the tv only as helper to render input options in the update form. It works as expected in the manager.

Orders are created programatically when a user checksout in the frontend.
a WAITING status is assigned to that order at creation time until the order is confirmed using PayPal IPN Message to change it to PAYMENT_RECEIVED

So i end up with a custom_order table with a order_status field where this is stored.
In the frontend i want to display the user's order history with cart items and status.

If i do something like

[[+order_status]]

the result will be "WAITING" instead of "Waiting for Payment"
I just feel the need of a reusable way of using TV as templates for outputting this data. (which is not linked to Resources)
An output filter maybe will suffice if i can extract input options from a given Template Variable called by its name.
Something like:

[[+order_status:renderWith=`helperTVname`]]

I can't find how to do it in the docs.

try this one. This should work with hardcoded inputOptionValues and with dynamic generated options by Bindings

//[[+status:optionstextoftv=`tvname`]]

$tvname = $options;

if (!empty($tvname) && $tv = $modx->getObject('modTemplateVar', array('name' => $tvname))) {
    $elements = $tv->parseInputOptions($tv->processBindings($tv->get('elements')));
    //$elements = explode('||', $tv->get('elements'));
    foreach ($elements as $element) {
        $opt = explode('==', $element);
        $value = count($opt) > 1 ? $opt[1] : $opt[0];
        $text = $opt[0];
        $text_array[$value] = $opt[0];
    }
}

return $text_array[$input];
