Default Problems with chapter 1

I have set up the unmodified source code on a couple of systems running PHP 5.2.5 / MySQL 5.x without any problems. Once I try to run in on my web account, a system running PHP 5.2.6 / MySQL 5.x, problem with the users class occur. First a handful of warnings like:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /<snip>/lib/User.php on line 87

I can get pass these by defining: "IS_ENV_PRODUCTION" as false. I also managed to iron out the second problem, that of an undefined variable: "filter_var($email, FILTER_VALIDATE_EMAIL)". Here I use an ereg().

Then I ran into a halt though. Once I try to register I get a positive: "Thank you for registering. Be sure to verify your account by visiting" but no data is written to the wrox_pending or wrox_user tables. Also, in the accompanying link to verify.php, the UID is always 0. The token is there but: uid=0.

I would be grateful for any pointers, thanks.

IS_ENV_PRODUCTION is intended to be set false when you're developing, and then set true when you role your code out into production. Changing that doesn't make the problem go away; it just suppresses the error messages.

It sounds like the code can't find the database tables. Did you remember to create the database and set up the tables as shown in sql/tables.sql?

I suspect that'll fix the problem you're having with filter_var() since then it won't be passing in an empty value.
