I'm kinda newbie in mysql r7. So I need help in making login/register system.

pawn Код:

public OnPlayerConnect(playerid)
{
    new query[200];
    format(query,sizeof(query),"SELECT * FROM `players` WHERE `Name`=%s",name(playerid));
    mysql_function_query(connection,query,true,"CheckAccount","i",playerid);
    return 1;
}

forward CheckAccount(playerid);
public CheckAccount(playerid)
{
    new rows,fields,temp[15];
    cache_get_data(rows,fields,connection);
    if(!rows)
    {
        ShowPlayerDialog(playerid,1,DIALOG_STYLE_INPUT,"Register","Register","Ok","quit");
    }
    else
    {
        ShowPlayerDialog(playerid,2,DIALOG_STYLE_INPUT,"Login","Login","Ok","quit");
    }
    return 1;
}

I don't know what am I doing(lol), the dialogs don't appear.
