Hi, thanks for the help, I just had a look at the db and they are just the
default tables, so that must be it. I'll let them know to either change
them over or add validation.
Again, thanks for your help.

Subject: Re: [PHP-DB] Problem with php and mysql
One of our customers has written a php application that we are hosting.
Basically, there is a province/state table which populates a combo box.
When the form containing this combo box is submitted, the information is
added into the database.
The problem is that when nothing is selected from the combo box, it adds a
number which seems to be random in the database, rather than the
province/state ID which it references from the province table. Obviously
there are many methods of avoiding this such as javascript to make sure
something is selected, or even giving the combo box a default value, but I
was wondering if anyone knew why the database itself isn't catching the
error (foreign key violation) and accepting the data.
Any ideas?
Are you using InnoDb tables? Otherwise there are no foreign key
restrictions.
How about some validation to make sure something is selected? Or, some
validation that'll give the value a default if nothing is selected.
Validate everything from the user!
