Greetings all, Although your Can't call method 'prepare' on an undefined value at... Error indicates to me that it is a problem with your $dbh not being initialized (perhaps post more code so we can see), I would also like to mention that you can alter your INSERT statement to see if it is in fact your SQL. Rather than: You could also do: This way you can map in the values you want to insert and you don't have to worry about AUTO_INCREMENT or TIMESTAMP fields since anything not specified in the field names list will get the default value from the databases column definitions. As well you can also do (update: at least in MySQL although its not standard SQL): INSERT INTO sponsor SET name=?, address=?, city=?, state=?, zip=?, country=?, contact=?, title=?, phone=?, bestime=?, email=?, license=?, type=?, capacity=?, distributor=? Which again allows you to specify which columns you want to insert and columns not specified get default values. Just some other approaches to your insert. However back to your error I would check that your $dbh is being successfully initialized. Should do it. side note: I have also seen people set AUTO_INCREMENT columns to 'NULL' to get values back... just a thought. Hope that helps
