Question

I’m trying to update a tuple in a table using php and sql via a website. Two of the attributes in the table are foreign keys that reference other tables.

$query="UPDATE store SET street='$street', city='$city', state='$state', zipcode='$zipcode', region_id='$region', manager_id='$manager' where id='$storeid'";
mysql_query($query) or die(mysql_error());

region_id and manager_id reference other tables and my query is failing as a result i think, because when i remove these two columns from the code then it executes fine.

how can i make this work? how do i make it so i can update this information and have it update the other two tables as well?

thanks for any suggestions and comments!

Answer 1

You will make it work when you provide values that are present in the referenced tables for the foreign key fields.
