Код:

#define mysql_host "localhost"
#define mysql_user "root"
#define mysql_password ""
#define mysql_database "test"

public OnPlayerConnect(playerid)
{
	new Query[80];
	GetPlayerName(playerid,pName,24);
	format(Query,sizeof(Query),"SELECT `Username` FROM `Users` WHERE `Username` = '%s' LIMIT 1;",pName);
	mysql_store_result();
	if(mysql_num_rows() != 0)//if number of rows is different from 0 then continue
	{
		format(string,sizeof(string),"Hey, %s! \nYour account is registered.\nPlease enter the password to log in!",pName);
		ShowPlayerDialog(playerid,DIALOG_LOGIN,DIALOG_STYLE_INPUT,"Log in",string,"Login","");
	}
	else
	{
		format(string,sizeof(string),"Hey, %s! \nYour account is not registered. \nPlease register to continue!",pName);
		ShowPlayerDialog(playerid,DIALOG_REGISTER,DIALOG_STYLE_INPUT,"Register",string,"Register","");
	}
	mysql_free_result();
	return 1;
}

stock LoginPlayer(playerid,const password[])
{
	new EscapedText[60],pName[24];
	new Query[80];
	GetPlayerName(playerid,pName,24);
	mysql_real_escape_string(password, EscapedText);
	format(Query,sizeof(Query),"SELECT * FROM `users` WHERE `Username` = '%s' AND `Password` = '%s'",pName,EscapedText);
	mysql_store_result();
	if(mysql_num_rows() != 0)
	{
		SendClientMessage(playerid,COLOR_GREEN,"You have been logged in!");
		LoadStats(playerid);
	}
	else
	{
		SendClientMessage(playerid,COLOR_RED,"Wrong password!");
		Kick(playerid);
	}
	mysql_free_result();
	return 1;
}

stock LoadStats(playerid)
{
	new pName[24],Query[80];
	GetPlayerName(playerid,pName,24);
	format(Query, sizeof(Query), "SELECT * FROM `users` WHERE `Username` = '%s' ", pName);
	mysql_store_result();
	mysql_fetch_row_format(Query, "|");
	sscanf(Query, "e<p<|>s[24]s[23]i>", PInfo[playerid]);
	mysql_free_result();
	GivePlayerMoney(playerid,PInfo[playerid][Money]);
	return 1;
}

if(dialogid == DIALOG_REGISTER)
	{
		if(strlen(inputtext) == 0)
		{
			ShowPlayerDialog(playerid,DIALOG_REGISTER,DIALOG_STYLE_INPUT,"Register - Enter your password","You are about to register a new account! \nPlease choose the password for it! \n","Register!","");
		}
		else

			mysql_real_escape_string(inputtext, EscapedText);
			format(Query,sizeof(Query),"INSERT INTO `users` (Username,Password,Money) VALUES ('%s','%s,'0')",pName,EscapedText);
			SendClientMessage(playerid,COLOR_GREEN,"You have been successfully registered!");

That's because you are just formatting variable named Query, you forgot to do mysql_query
You have to do the following after the format line

Код:

mysql_query(Query);

what do you mean by connection handler,sorry i am new in this

[BleverCastard]

Under OnGameModeInit, you will have something like:

pawn Код:

ConnectionHandle = mysql_connect(...);

You use ConnectionHandle as the connection handler. Please don't take this and dump it into your gamemode, it will be different.

still can't understand :

can you help me with an example

Код:

new Query[80];
	GetPlayerName(playerid,pName,24);
	format(Query,sizeof(Query),"SELECT `Username` FROM `Users` WHERE `Username` = '%s' LIMIT 1;",pName);
	mysql_query(Mysql,Query);
	mysql_store_result();

[BleverCastard]

No, that's not even remotely close to what I said.
I said under OnGameModeInit not OnPlayerConnect.

And what do you mean "can you help me with an example" I gave you a perfectly reasonable one above.

[Nabster]

I tried,this is what i have done

new MySql = -1;

OnGameModeInit()
MySql = mysql_connect(mysql_host,mysql_user,mysql_database ,mysql_password);



new Query[80];
GetPlayerName(playerid,pName,24);
format(Query,sizeof(Query),"SELECT `Username` FROM `Users` WHERE `Username` = '%s' LIMIT 1;",pName);
mysql_query(MySql,Query);

but still its not saving my username everytime i reconnect its asks me to register

pawn Код:

new MySQLConnection;

pawn Код:

MySQLConnection = mysql_connect(MySQL_Host, MySQL_User, MySQL_DB, MySQL_Pass);
