Custom domsetic flat rate shipping not picked up while ordering

[elibaba]

Hello,

I've duplicated the default flat shipping module to offer cheaper domestic flat rate shipping, only in my domestic zone.

All works fine, except that when a customer picks the radio button for my domestic_flat module (e.g picks in the store front "flat rate domestic shipping" on checkout_shipping page) - they arrive to the next page, checkout_payment, with the worldwide flat rate selected!

This makes customers unable to select the domestic_flat shipping module option, so I am forced to use storepickup for that as a workaround, but than storepickup is not offered as the default in the shipping estimator even if it's the cheapest... (by design, so I understand).

I am positively sure I wrote the domestic shipping module fine, as well as configured it. No debug messages are in the cache dir.

Where can I look to understand the logic, why a shipping option other then the one selected in the storefront in applied ?

I'm on Zen Cart 1.3.8a, PHP Version 5.2.8.

Thanks for any hint!

If you took the Flat Rate flat.php shipping module and cloned it for Domestic Rate by copying the files:
/includes/modules/shipping/flat.php
/includes/languages/english/modules/shipping/flat.php

to the files:
/includes/modules/shipping/domestic_flat.php
/includes/languages/english/modules/shipping/domestic_flat.php

or to something like:
/includes/modules/shipping/flat_domestic.php
/includes/languages/english/modules/shipping/flat_domestic.php

then you have an error ...

You really want to use either:
domesticflat
flatdomestic

the _ in the filename and where you changed FLAT to FLAT_DOMESTIC and flat to flat_domestic are causing a conflict ...

Really ? the underscores aren't allowed in php file names ?

I'm checking this right away!

Thanks

Underscores are fine in php filenames ... the problem is in tihs particular instance of the way the classes are written that the functions etc. will fail on the modules if you clone one such as flat.php to make flat_something.php the flat and flat_something will conflcked in one area or another in the module and make some pretty weird things happen ...
