Login Issue
#1

Hi, I have this problem, where my script returns "Invalid Password" message. The password is saved when a player registers, and hashed using MD5. In the database, field "password" is formatted as char(32), which produces no more "sscanf warning: string buffer overflow" when entering the password, as I had that before.

Instead, the script now triggers the else clause, giving me a three time warning about an Invalid Password, as scripted in my code. I also verified that MD5 is correct, by dehashing it, and it gives me my password back, which is "testing". How can I fix this?

This is from MySQL debug:

Код:
[23:45:21] >> mysql_real_escape_string( Connection handle: 1 )

[23:45:21] CMySQLHandler::EscapeString(HighFlyer); - Escaped 9 characters to HighFlyer.

[23:45:21] >> mysql_query( Connection handle: 1 )

[23:45:21] CMySQLHandler::Query(SELECT * FROM `Accounts` WHERE `Username` = 'HighFlyer' AND `Password` = md5('testing')) - Successfully executed.

[23:45:21] >> mysql_store_result( Connection handle: 1 )

[23:45:21] CMySQLHandler::StoreResult() - Result was stored.

[23:45:21] >> mysql_num_rows( Connection handle: 1 )

[23:45:21] CMySQLHandler::NumRows() - Returned 0 row(s)
It seems to cut off there with no rows returned, but why? Here's my code:

Код:
stock Dialog_Login(playerid)
{
    new str[128];
    format(str, sizeof(str), "{FFFFFF}Welcome back to San Andreas Transport Clan {33FF33}%s\n{FFFFFF}Please login with your password below:", Player[playerid][Username]);
    ShowPlayerDialog(playerid, DIALOG_LOGIN, DIALOG_STYLE_PASSWORD, "{FFA19C}Welcome back, please login to SATC", str, "Login", "Cancel");
}
Код:
case DIALOG_LOGIN:
		{
		    if(!response) // Cancel
		    {
				Kick(playerid);
				return 1;
			}

			if(!inputtext[0])
			{
			    SendClientMessage(playerid, RED, "Error: Please enter a password.");
				Dialog_Login(playerid);
				return 1;
			}

			new esc_password[MAX_PASSWORD_LEN], query[512];
			format(esc_password, sizeof(esc_password), "%s", inputtext);

			mysql_debug(1);
			format(query, sizeof(query), "SELECT * FROM `Accounts` WHERE `Username` = '%s' AND `Password` = md5('%s')", GetPlayerEscapedName(playerid), esc_password);
			printf(esc_password);
			mysql_query(query);
			mysql_store_result();
			
			if(mysql_num_rows() != 0) // Password is correct
			{
			    new result[1024];
				mysql_fetch_row_format(result);
				printf("Password is correct.");

			    if(sscanf(result, MYSQL_PLAYER_LOAD_FORMAT, Player[playerid]))
			    {
					printf("MYSQL_PLAYER_LOAD_FORMAT OK");
			        WipeChat(playerid);

			        SendClientMessage(playerid, WHITE, "There was an error with the format of your account data.");
			        SendClientMessage(playerid, WHITE, "Please take a screenshot, if you know how, and post it as a bug report.");
					SendClientMessage(playerid, WHITE, "Forums: "FORUMS"");

					Kick(playerid);
					mysql_debug(0);
					printf("MYSQL_PLAYER_LOAD_FORMAT END OK");
					return 1;
				}
				
				OnPlayerLogin(playerid);
				printf("We have been successful");
			}
			else
			{
				Player[playerid][LoginAttempts]++;

				format(str, sizeof(str), "Error: Invalid password (%d/%d)", Player[playerid][LoginAttempts], MAX_LOGIN_ATTEMPTS);
				SendClientMessage(playerid, RED, str);

				if(Player[playerid][LoginAttempts] >= MAX_LOGIN_ATTEMPTS) // He has tried to login MAX_LOGIN_ATTEMPTS times (or more if that was to somehow happen..)
				{
					SendClientMessage(playerid, RED, "Error: Too many login attempts, you have been kicked.");

					Player[playerid][LoginAttempts] = 0;
					Kick(playerid);
					return 1;
				}
				
				Dialog_Login(playerid);
			}

			mysql_free_result();
		}
I only managed to get the first printf(esc_password). The rest have not been returned by the script into the console. This line also returns a warning, that I think could be the culprit, but I have no idea why it does that.
