Reply To: User voting system problem

[__]

I’m still not really sure how I test for users with less than 10 votes or no votes at all though?

I think @jurotek pointed this out earlier, but you’d simply use left join instead of a regular join. This way, you get all results from the user table that don’t have a matching vote.

I can add a vote once which works fine and if I try to vote again I get a SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry ‘2’ for key ‘PRIMARY’error.

Which points out how you can manage errors: if you get an SQL error, check if the error code was 23000. If so, you can display a message to the user along the lines of “You’ve already voted.”
