I have a plugin that connect Tookan delivery system ([login to view URL]) to Woocommerce.
I would like to makes some little changes on it:
1)Now the plugin have in wp-admin a little interface where user can paste their Tookan API. I would like to add there a new backend interface that make possible to select for each shipping method and zone set in Woocommerce which one to send via API to Tookan and which not;
2)For each shipping method and zone that user has select that will be sent to Tookan API user will have another interface. In this interface user will be able to select a date and time for the delivery (these data will be sent to Tookan system). The date must be dynamic, so user will be able to say today, tomorrow, the day after tomorrow. Everything compare to the present date of the wordpress installation.
I attached to this description the working plugin how it is now. From this starting point you have to make the 2 changes.
