I want free members on my site to send only 2 messages Is that possible I know I have to set and running a query on phpmyadmin... but I don't know the steps. I explore phpmyadmin and I click on QUERY tag. Now I see there also rules about running a query like Field: Sort: Show: Criteria: And: Or: Modify: Update and Modify I see also newflag on Field: rules. So if you tell me the steps I thing I can do it.
Yes, it is possible. But one can do only if he/she knows your application and database structure. In your application, there should be an option to set the number of messages a user can send. Try to figure out that point.
Sounds like you need to read up on SQL (structured query language) - when you've got the SQL you're after you can embed this into your web pages so that the query is run (checking for how many messages your users have entered) and you can give the users access to send a new message or not... Do you have a table/mechanism that is currently collecting your users activity? If you show us that we can help you build a script/query to check this Good luck!
What are you current table fields? Is there a field that determine the number of messages? If none, you can add a column in your database table and use the value on that new column to limit the number of messages.
