Working on a sort of a poll plugin. On each anwser in the poll there is a "vote" submit button that is connected with the answers ID.
At first, I used the $wpdp->update to increase the value by one. With that solution the submit button only worked once per answer. Don´t know the reason for that though.
Another member at this forum helped me out and said I should use the £wpdp->insert method instead, when I tried that some new rows where added to the table.
So, my question is, how do I write a ->insert statement that only increases the value? Or, how do I write a update ->update statement that can be used more than once.
If you have any questions about my database setup or similiar, tell me! =)
