How can i modify the share button script to be added to my web page, but with reference capabilities.

Scenario:

Currently my website has the share button. I want this share button, when clicked; a box should pop up asking to enter his of her name.

Then when the name has been entered, the sharing would be posted on FB. The link should be having my name on it.

e.g: http://www.domain.com/ref=gopi

The reason why i want this is because, on the website there is a inquiry form, where when users visit this website and they seem interested to know more, they could fill out the inquiry form.

The problem is users who fill out the inquiry form sometimes forget to fill out the introducer information, and this has caused the leads to go to anybody, coz we don’t know who is it from.

So if anyone who clicks on the shared link with the example address (http://www.domain.com/ref=gopi), on my webpage the name gopi is automatically inserted into the introducer column.

Hope to get a reply soonest, and have a great day.

Please also advice if you don’t understand the scenario. It’s more like affiliate marketing the links.
