Magento Custom Shipping Module - How to create multiple delivery options?

[amedeos]

Hi everyone,

I'm building up a custom shipping module based on my particular needs.

As a base, I'm using the one from the user MunchyMonster on magento's forum several years ago (=http://www.magentocommerce.com/boards/viewthread/7247/P0/).

 

Basically, MunchyMonster's module was set up in such a way to add 3 different flatrates based on postcodes without using any matrix rate table.

It was simple but it served the purpose.

 

Now, my needs are slightly different. I'm trying to use the 3 Zip Codes Tiers from MunchyMonster's module as 3 different Free Delivery options.

I'm trying to set up free delivery to specified postcodes on a certain day, if the order is placed within a specific time range of the week.

 

I offer free delivery on Tuesdays and Thursdays, if orders are placed within a time range in the week. For instance, if the customer misses the cutoff time of Tuesday, Tuesday delivery is automatically disable. So far I succesfully set up the first tier with php, in order to follow this behaviour (time range, activation etc).

So the module works and shows up in the front and back-end.

 

However, I'd need the module to display Thursday Free Delivery as an option, too. Ideally that could be done by using the 2nd tier of the module as a shipping options.

Unfortunately MunchyMonster's approach was such that just one of the Tiers could be used at once, and at the end a single shipping option would be fed to magento, as opposed to an array of shipping options.

If look at the code below (I'm using the original code because mine would be more complicated to check, due to all the conditional statements) you'll see that 3 tiers from the backend (see backend) cannot be used (and thus displayed in the front end at the same time).

 

Does anyone know how could I have this thing sorted (or at least point me in the right direction?). Although I have some php knowledge, I'm by no means confident in working with magento classes.

 

The fully operational module (without my conditional statments, for the sake of simplicity, can be found here:
