Extension which is NOT module/payment, only 1 instance

Hi

Thanks for this forum. I am so glad that i can ask here for help!

I am creating an extension for opencart 2.1.x til 2.2.x.

My extension only needs to keep some general settings within admin, no Frontend catalog files needed.
Lets assume for simplicity's sake it only holds facebook and twitter id.
The settings should not be under settings since there is no need to make it multishop.
extension should save in oc_setting and NOT in oc_module table
Only 1 instance.
I want the menu-entry not to be auto created but i want to add it with ocmod (already done).

I started with copying the Html module and renaming, all working fine. The problem is that after every save of the module a NEW INSTANCE (Module id+) is created. But i want only 1 instance being possible. Can i create a module with only 1 instance?? How to change the code that this happens in the bitbucket module i link at the end?

Could you give me a start?

the module i use for a start is quite identical to https://bitbucket.org/mariavilaro/openc ... module/src this one.

Then you should know what to do.
One question: should that module be for you only (your own shop), a client or a commercial module?

Hi OsWorx

Only for me (my shop). Why does this matter? It would be funny if i work for others without any idea what to do . No, its for my wine shop.

OpenCart 2.x has two types of modules. I refer to these as "independent" and "global" modules.

Independent modules allow for multiple instances of the module and store their settings in the module table in your database. The HTML module is one of these.

Global modules only allow for a single instance of the module and store their settings in the setting table in your database. The Account and Category modules are examples.

You should use the Account or Category module as a starting point for your own custom module.
