Hello,

[snip]
I suspect that the problem is with file permissions. I recall that since
Metabase uses include to load class files, the script will not exit when
it fails to include a PHP class file. Assuming that is the case, make
sure that all Metabase class files are readable by your Web server user.
[/snip]
The permissions seem fine. However, I've discovered something else.
I was able to use Metabase without any trouble on a linux server to
access a Postgres database. I then removed the call to
MetabaseSetDatabase and changed the drive to odbc-msaccess, and the
errors returned. Changed it back to pgsql or mysql and the errors go
away.
I just now tried this on the IIS box and got the same results. If I
specify postgres I get an error telling me that postgres is not enabled
in that php implementation, and if I specify mysql it works fine. If I
change it back to odbc-msaccess, the errors are there.
So, the error message I get is only triggered when I specify Access as
the database.
Does this provide any further insight?
Not really but I looked again at your error message and sample script
and realized a few things that seem to be the problem.
Your error message said:
Fatal error: Class metabase_manager_odbc_class: Cannot inherit from
undefined class metabase_manager_database_class in
C:\Inetpub\wwwroot\etrakFE\classes\metabase\metabase_odbc.php on line 13
There is no class definition on line 13 of metabase_odbc.php . That
definition is in manager_odbc.php. So I wonder if you did not typed the
error message with inadverted changes.
In your example you call SetDatabase. That does not make Metabase load
the ODBC driver schema manager extension. I suspect that you meant
CreateDatabase. That would trigger the extension class loading and
eventual errors.
If you are sure permissions are ok, the only other possibility to make
the class loading include fail is incorrect include path. I suspect you
need to specify absolute path to make it work. What is your include path
in php.ini?
Anyway, I changed Metabase base class to make it gracefully fail (not
make PHP exit with a fatal error) if any of the extension include files
does not load properly for some reason.
Please try the updated version getting it from CVS or a current snapshot
that you can download from here:
http://www.meta-language.net/download.html#snapshots
Metabase is inside the archive:
http://www.meta-language.net/download/metal-cvs.zip
or
http://www.meta-language.net/download/metal-cvs.tar.gz
Once you use this version your script should no longer exit with a fatal
error. It should fail but a call to $db->Error() should return a
meaningful error message.
