[Urefeu]

Hello

I've a little script for connecting to my server :

Код:

new query[128], data[256];
	GetPlayerName(playerid, pPseudo[playerid], sizeof(pPseudo[]));
	
	format(query, sizeof(query), "SELECT `password` FROM `members` WHERE `pseudo` = '%s'", pPseudo[playerid]);
	mysql_query(query);
	mysql_store_result();
	
	if(mysql_fetch_field("password", pPassword[playerid])) {
		new sConnexion[128];
		format(sConnexion, sizeof(sConnexion), "{009FFB}Hello, {0032FB}%s !\n\n{009FFB}Please enter your password :", pPseudo[playerid]);
		ShowPlayerDialog(playerid, 1, DIALOG_STYLE_PASSWORD, "Connexion", sConnexion, "Connexion", "Exit");
	}

The problem is that when I go on this server, it is rebooted and the script doesn't function.

Here is mysql_log.txt :

[Mon Jul 02 18:43:52 2012] Connected (0) to root @ localhost via TCP/IP.

Thanks in advance !

Try with this:

pawn Код:

new query[128], data[256];
GetPlayerName(playerid, pPseudo[playerid], MAX_PLAYER_NAME);

format(query, sizeof(query), "SELECT password FROM members WHERE pseudo = '%s'",pPseudo[playerid]);
mysql_query(query);
mysql_store_result();
if(mysql_num_rows())
{
    if(mysql_fetch_field("password", pPassword[playerid]))
    {
        new sConnexion[128];
        format(sConnexion, sizeof(sConnexion), "{009FFB}Hello, {0032FB}%s !\n\n{009FFB}Please enter your password :", pPseudo[playerid]);
        ShowPlayerDialog(playerid, 1, DIALOG_STYLE_PASSWORD, "Connexion", sConnexion, "Connexion", "Exit");
    }
}

Best regards!

Hello !

I always have my error...

if(mysql_num_rows()) and if(mysql_fetch_field("password", pPassword[playerid])) do the same thing : the first check if there is a row in the result of the query and the second check if there is a password field (so nearly a row) in the result. Sorry for my bad english :P

Do you have an other idea ?

Thanks always !

[Urefeu]

No one has ideas? It completely blocks me :/

Please

Let me try something.

EDIT:
This line gives me doubts:

pawn Код:

mysql_fetch_field("password", pPassword[playerid])

I think its parameters are:

pawn Код:

mysql_fetch_field(value, destination[]);

//---Example:
new save_here[40];
mysql_fetch_field(2, save_here);

I mean, you're using it wrong.

Are you using BlueG's MySQL plugin?

Try with this:

pawn Код:

new query[128], data[256];
GetPlayerName(playerid, pPseudo[playerid], sizeof(pPseudo[]));
format(query,128, "SELECT * FROM members WHERE pseudo = '%s' LIMIT 1", pseudo[playerid]);
mysql_query(query), mysql_store_result();
if(mysql_num_rows())
{
    new sConnexion[128];
    format(sConnexion, sizeof(sConnexion), "{009FFB}Hello, {0032FB}%s !\n\n{009FFB}Please enter your password :", pPseudo[playerid]);
    ShowPlayerDialog(playerid, 1, DIALOG_STYLE_PASSWORD, "Connexion", sConnexion, "Connexion", "Exit");
} else {
    //Register dialog here.
}

Thank you very much, that functions !

Now, the problem is that when I do that, the server crash :

Код:

new query[128], data[256];
GetPlayerName(playerid, pPseudo[playerid], sizeof(pPseudo[]));
format(query,128, "SELECT * FROM members WHERE pseudo = '%s' LIMIT 1", pseudo[playerid]);
mysql_query(query), mysql_store_result();
if(mysql_num_rows())
{
    new sConnexion[128];
    mysql_fetch_field("password", pPassword[playerid]); // I have added this line
    format(sConnexion, sizeof(sConnexion), "{009FFB}Hello, {0032FB}%s !\n\n{009FFB}Please enter your password :", pPseudo[playerid]);
    ShowPlayerDialog(playerid, 1, DIALOG_STYLE_PASSWORD, "Connexion", sConnexion, "Connexion", "Exit");
} else {
    //Register dialog here.
}

I use this plugin by StrickenKid : https://sampwiki.blast.hk/wiki/MySQL_Plugin

The parameters are : mysql_fetch_field(const fieldname[], dest[], MySQL:handle)

What is wrong in my code ?

Here is an example of code with this plugin : http://www.strickenkid.com/mysql_plugin/example.pwn

In the second /login, you can see that he do the same thing as me when the server crashed...

I don't understand :/

[[DOG]irinel1996]

Can you show me pPassword array please?

Yes, I see, strange... Let's take a look at your variables.

Use [pawn] tag please!

PD: "That functions" ? (functions = works) (That works) I understand you because I speak three languages. xD
_______________________________
EDIT:
Try this, as I saw StrickenKid uses a 256 cells array.

pawn Код:

new pPassword[MAX_PLAYERS][256];

[Urefeu]

The strangest thing is that when I run the server and I connect, the server crash with the code of previous post.
By cons, when a friend logs on (her nickname is not in the database so it goes into the else who does anything yet) and after I connect, my script works perfectly for me to log ...

EDIT : new pPassword[MAX_PLAYERS][64];

You can see that when my friend logs on before me, my connection works. By cons, when I log in first, the script stops at mysql_fetch_field ... It's really strange ...
