Default Code: Player Flags (Perl and Command)

Hello all.
For awhile now I've been meaning to finish this command to restrict access to zones if you dont have a certain flag. After alot of reworks Ive got a working version.

It works very simply. Here is the schema:
Code:
DROP TABLE IF EXISTS qflags;
CREATE TABLE qflags (
  charid varchar(64) NOT NULL,
  zoneid int(11) NOT NULL default 0,
  UNIQUE KEY qflag (charid,zoneid)
) TYPE=MyISAM;

alter table zone add qflagreq int(2) NOT NULL default '0';
Below is the code, and below that will be the syntax for #qflag and quest::qflag();. How the code works is it checks qflagreq to see if the zone requires the client to have a flag to enter. If it is 0, it skips the qflag code. If it is 1, it will require a flag. It will then look up the user in the qflag table for that specific zone id. If the flag doesnt exist, the user will not be able to enter. If they do have a flag, the zone will process the user and send them off normally.

Database.cpp
FIND:
Code:
		cerr << "Error in GetLiveChar query '" << query << "' " << errbuf << endl;
		safe_delete_array(query);
	}
	
	return false;
}
ADD AFTER:
Code:
//Cisyouc: Begin qFlag Checks
bool Database::ControlqFlag(const char* name, uint32 zoneid, bool adding)
{
	char errbuf[MYSQL_ERRMSG_SIZE];

	{

Syntax:
Help: #qFlag 1 help
Help w/Quests: #qFlag 1 1
Help w/Commands: #qFlag 1 2
Flag Player: #qFlag 2 [charname] [zoneid]
De-Flag Player: #qFlag 3 [charname] [zoneid]

Perl Syntax:
Add Flag: quest::qflag(1, [zoneid]);
De-Flag: quest::qflag(2, [zoneid]);

So, again, to make a zone require a flag, do this mysql query:
Code:
UPDATE zone SET qflagreq='1' WHERE zoneidnumber='xxxx';
(Replacing xxx with the zone id)

Thanks to the guys at #perl for catching my stupid mistakes

Let me know what you think of this.

Double check the primary key on your schema.

Under that schema, a character can be flagged for only one zone at a time.

Code:
c:\documents and settings\adamxp\desktop\eqemucvs\source\common\database.cpp(1170) : warning C4715: 'Database::GetqFlag' : not all control paths return a value 



command.cpp(865) : warning C4805: '==' : unsafe mix of type 'char' and type 'bool' in operation
command.cpp(888) : warning C4805: '==' : unsafe mix of type 'char' and type 'bool' in operation
Other than that compiled great. Thanks Cisyouc. For those of you without a compiler, I added it here http://www.eqemulator.net/forums/viewtopic.php?t=17924

Hmmm. I'm not getting those warnings, ajb. Regardless as long as #qFlag works its not worth worrying about =)

Not to be a pedant, but it is good practice to fix warnings. Just because it works now does not guarantee it will work later on, or in another situation (ie: for someone else).
