Little help with yet another advanced query...

[JJR512]

Suppose I want to add a new settinggroup and settings to the vBulletin Options section of the admin cp. I know that to do this, I add a new record to the settinggroup table, like so: INSERT INTO settinggroup (settinggroupid,title,displayorder) VALUES (xx,"Group Title",xx);. I also know that to add settings to that setting group, I would use something like: INSERT INTO setting (settingid,settinggroupid,title,varname,value,desc ription,optioncode,displayorde r) VALUES (nn,xx,"Setting Name","$varname","1","Description about setting","yesno",yy);.

Now my question is, if I use NULL for xx while creating the settinggroup so that it takes the next auto-increment number, is there a way I can do the second query, making the setting, so that it uses the same number for xx? Some kind of join or something where it looks in settinggroup for a settinggroupid where the title equals "Group Title"?

After running the first query (INSERT INTO settinggroup), do this:
$newSettingGroupID = $DB_site->insert_id();
// Same as mysql_insert_id();
And then use $newSettingGroupID as XX.

So I'd have to do it as a script, and not as a simple query straight to the db?

You could run these two queries, one after another:
INSERT INTO settinggroup (settinggroupid,title,displayorder) VALUES (null,"Group Title",1);
INSERT INTO setting (settingid,settinggroupid,title,varname,value,desc ription,optioncode,displayorder) SELECT null,LAST_INSERT_ID(),"Setting Name","varname","1","Description about setting","yesno",1 FROM settinggroup LIMIT 1;

This is how I did the exact same thing in the installer of my Default PM-hack.

SELECT @displayorder:=displayorder+1 FROM settinggroup ORDER BY displayorder DESC LIMIT 1;
INSERT INTO settinggroup (title, displayorder) VALUES ('Default PM', @displayorder);
SELECT @settinggroupid:=LAST_INSERT_ID();
INSERT INTO setting (settinggroupid, title, varname, value, description, optioncode, displayorder)
VALUES (@settinggroupid, 'Send default PM to new users?', 'defpmactive', '0', '', 'yesno', 1);

Umm, Chen... The board did some strange parsing when I posted that inside [sql ] instead of [code ]
