DBI layer Conversion

Posted: Fri Nov 07, 2008 11:03 pm

Well generally speaking there only a few general things you need do.

First is change the $dbi global (Your block my have more globals)

Code:




global $prefix, $dbi;

Code:




global $prefix, $db;

Then you need to remove the $dbi from all the quries.

Code:




$result = sql_query("select lid, title, hits, url from ".$prefix."_links_links order by linkratingsummary DESC limit 0,$mainlinkstoshow", $dbi)

Code:




$result = sql_query("select lid, title, hits, url from ".$prefix."_links_links order by linkratingsummary DESC limit 0,$mainlinkstoshow")

Finally you have to change the "query functions"

Code:




sql_query("select lid, ti .........

Code:




$db->sql_query("select lid, ti .........

You need to be carefull because all the functions are not like sql_query were you just append the $db->. For example with the old $dbi way you used sql_fetch_row(), but with the new way it has to be written $db->sql_fetchrow(). There are only a couple of functions that you will need to change, so just check in the newer blocks if you need help with one. Off the top of my head I can't think of the other functions that are different from old to new.

OLD:
sql_query($sql, $dbi)
sql_num_rows($sql, $dbi)
sql_fetch_row($sql, $dbi)
sql_fetch_array($sql, $dbi)
sql_fetch_object($sql, $dbi)
sql_free_result($sql, $dbi)

NEW:
$db->sql_query($sql)
$db->sql_numrows($sql)
$db->sql_fetchrow($sql)
$db->sql_fetchrow($sql)
$db->sql_fetchrow($sql)
$db->sql_freeresult($sql)

Excellent. Thank You Palbin!

You might also want to turn database error reporting on (see documentation in rnconfig) when you are doing the conversion and monitor the dblog file. Of course, if the function never gets to the database layer it won't show up in the log but it could show any function calls that aren't correct.

Just remember to turn the error reporting off when you are done or else monitor the dblog regularly.

Excellent. I was totally confuddled about sql_fetch_anything. Smile

Thank you.

Nice reminder, Palbin, thanks! I'm pretty sure Chatserv wrote a similar tutorial a few years ago on nukefixes or nukeresources.

Followed the instructions closely I think but my last 10 forums block, center down, in table format does not work. When activated, the left and right side blocks are missing altogether, here's the code:

Code:

What did I miss? It works just fine in the last RN version, running 2.3 now, default theme RavenIce.

Edit: I missed the fetch_row but changed it to fetchrow but didn't change anything.

I created the file "dblog". Is that it, no extension? Also did the permissions to 666 but I get nothing in the file when trying my top 10 forums file above.

Edit: Cripes, I placed it in the root instead of /rnlogs and there is already a dblog file there, just had to change the permissions. Sad

And nothing shows up in the dblog when the broken block is activated.

Cheers, Jay

Thank you again! I finished up with my latest forum block, then I updated the Admin module "VersionNumber" which took all of 1-2 minutes!

Best regards,

dad - change all instances of sql_fetch_row to sql_fetchrow and you should be good to go.

Posted: Wed Dec 24, 2008 11:19 am

gotcha - Note:

Edit: I missed the fetch_row but changed it to fetchrow but didn't change anything.

Already did that, no luck.

Cheers, Jay

EDIT: The block may be too "old" to modify. If that is the case I would like a compatible "Last Posts" block in table format, not like the "block-forums.php" that is included.

Posted: Wed Dec 24, 2008 12:01 pm

Nothing is too "old".

Posted: Wed Dec 24, 2008 3:06 pm

I think you can also do

Code:




  list( $auth_view, $auth_read ) = mysql_fetch_row( $result1 );

Posted: Wed Dec 24, 2008 3:50 pm

yes, but this thread is about conversion Smile

$db->sql_fetchrow($sql)

Posted: Wed Dec 24, 2008 5:03 pm

Nothing posted here is working to convert my particular block. Since when the block is activated, the right and left blocks are completely missing which leads me to believe that it's more serious than just DB conversion.

Cheers, Jay

Posted: Wed Dec 24, 2008 9:40 pm

Give me a few days I'll fix it. Also I am going to split this into a new thread. It really shouldn't be in this one.

Yes but

Code:




$result1 = $db->sql_query( "SELECT auth_view, auth_read FROM ".$prefix."_bbforums where forum_id = '$forum_id'", );


      list( $auth_view, $auth_read ) = mysql_fetch_row( $result1 );

should still work as $result1 contains both a persistant connection and the query Wink

Posted: Thu Dec 25, 2008 3:24 pm

Does not work, I don't think that's where the problem lies as there is no display of the table and both right and left blocks do not show.

Cheers, Jay

Try this:

Posted: Fri Dec 26, 2008 7:44 am

Thank you, that works just fine. We're back in business. I compared the new to the old and quite a bit of difference.

Cheers, best of the holidays.

Posted: Fri Dec 26, 2008 10:20 am

The big difference is that I added in some code to allow the block to consider the users time zone. The times in the block should match the times in the forums.
