Data extraction from database by user name .. "ABC" records the user name screen print. How can I do?
I'm not sure you've explained the problem properly. Is this your site you are trying to get data from? The username should have an ID against it (here my username is sarahk, my id is 29) and that userid will be a "foreign key" in other tables too.
Is there a field with the user name? As for screen print, any web browser will allow you to print, so I'm not sure what you are looking for, otherwise I have a script that will do what you want, but I need more information such as variables, etc...
