2 questions (string customization + package upgrades)

Hello,

I am a developer and customizing a GeoDir based site for my client. I have 2 questions for you:

1. Is it possible to use conditional constant definitions in language.php in the future versions?
E.g. if I want to use a custom string for
define(‘NEW_USER_TEXT’, __(“New User? Register Now”, ‘geodirectory’));

then I can pre-define this string in my child theme like this:
define(‘NEW_USER_TEXT’, __(“Click here to Register”, ‘geodirectory’));

However, in this case WP_DEBUG throws me warnings (I always develop with DEBUG ON, so it’s a bit annoying).

If you used conditional constant definitions in language.php, like:
if ( !defined( ‘NEW_USER_TEXT’ ) ) define(‘NEW_USER_TEXT’, __(“New User? Register Now”, ‘geodirectory’));

then I could simply overwrite these strings and wouldn’t need to use tricky and hacky solutions in some places.

2. Upgrade listing packages in the front end

We are using the Payment Manager add-on (my client has the license for it, thus I’m asking here), however, I couldn’t figure out yet how we could Upgrade a free listing to a paid one.

We have 2 packages: Free and Premium.

What I would like to achieve is the following:
– User adds a Free listing
– Later, thanks for our marketing strategy, they decide to upgrade to the Premium one
– User goes to the listing’s single page, clicks on a link that says “Upgrade to Premium” (or something similar)
– Fills out the Premium form and pays

Is it something we can achieve somehow? Did I just miss something is the setup screens?

Our theme is based on Supreme Directory.

Thanks in advance,
Ervin
