    How can catch a message from MySQL if a unique constraint is violated?

    When i do an insert from a php-form to MySQL, which violates a unique constraint, i don't get an error message, just the data is not inserted.

    Print out mysql_error() after your INSERT command. The error is being generated. See what the error looks like, then you can create some kind of IF statement looking for keywords relating to unique error.
