Only allow sub domain order

[mroxidane]

For some reason, we would like to block  activating our service with main domain.

I mean, we will only allow sub  domain orders to be processed.

Please do not misunderstand, we are not offering sub domains from our domain. Customers must use a sub domain using their own domain to purchase our service. I do not want to make changes on the template or add any hooks, because we are also having reseller system for this specific product, meaning, we get orders from reseller whmcs too.

So we want to block it from WHMCS admin side, we will hightlight it that customers must use a sub domain. But in case if someone orders with their main domain name, their order should not auto provision, instead it should be in pending state and we will cancel it informing the customer that they should use a sub domain instead.

This is the main idea, our product is specifically developed to be used with a sub domain.

For example, users should order the service with sub.userdomain.com NOT userdomain.com However, the sub domain is not restricted, they can use any prefix of their choice.

Is there no solution to this?

I think a product custom field might be the simplest way to collect your client’s preferred 3rd—level domain…

I don't think WHMCS  support  cPanel account provisioning with domain from custom field. I tried but failed.
