+----+---------------------+-------------------+-------+-------------------+ This was the query I was using: $query = "INSERT INTO guitarwars (date, name, score, screenshot) VALUES (NOW(), '$name', '$score', '$screenshot')"; It seems to be inserting a default value of 0 since the id is not being specified and that's when I realized that I had failed to auto_increment the id column. D'oh! So once I did that everything worked like a charm. @Ken

First -- NEVER post code with your database username/password. Since you

did, change your db password immediately. Well actually I did not. Did you really think 'secretsauce' was my password? :) But I guess you're right in that this may be a little ambiguous when seeking advice in lists so from now on I will take your advice on making login information unambiguously fake in the form of user='xxxx' and password='xxx'. @Stuart But take note of what everyone else is saying. You should be getting the error message when this happens which will tell you exactly what the problem is, above and beyond "Cannot insert query" (which, btw, makes no sense at all :)). Ok well I'm using an 'insert' query so I'm not sure why you say that this makes no sense at all. :)) If you don't mind giving this n00b advice what would be a better/more accurate error message? They take away from this for me was.. don't skimp on the error messages! The one I got was so clear that fixing the problem was easy at that point. But thanks again guys.. this list has been an indispensable source source of wisdom on my journey in learning PHP. Tim Thanks again guys, Tim I think the comment about your "cannot insert query" was because it really did not make sense. Once truly cannot "insert a query". Since you ask tho, a more approp message might be

"Insert query failed to execute.<br>Error returned was " . mysqli_error() . "<br>Query was $q" As for your index issue - you are using an autoincrement(?) field as the primary key. Is this related to another record in your db? If not, why even have the primary key?
