Major discovery of discuz DB layer cross-database mapping relationship table name prefix BUG, ​​discuz relationship table

Scenario:

Create a Table model in Discuz, but the Table is not in the same library as Discuz.

Discuz seems to provide a cross-library mapping mechanism after version 3.

There is no problem with the mapping. The main reason is that the table name prefix is ​​not mapped accordingly. Of course, it's not actually a bug. Because he only considers discuz's own system, generally speaking, the table name prefixes are the same.

In the db driver class, db_driver_mysql(i):

Append code to function table_name

<span>if</span>(!<span>empty</span>(<span>$this</span>->config[<span>$id</span>]['tablepre'<span>])){
                </span><span>$this</span>->tablepre = <span>$this</span>->config[<span>$id</span>]['tablepre'<span>];
            }</span>
