Problem with DataPacks
 
PHP Code:
public MenuHandler(Handle:menu, MenuAction:action, param1, param2)
{
    if (action == MenuAction_Select)
    {
        new Handle:data = CreateDataPack();
        WritePackCell(data, param1);
        SQL_TQuery(db, CheckDB "some query", data);
    }
}

public CheckDB (Handle:owner, Handle:hndl, const String:error[], any:data)
{
    new client = ReadPackCell(data);
    PrintToChat(data, "test");
} 

Code:
[SM] Native "PrintToChat" reported: Client index 431227078 is invalid
Why? How to fix?

Re: Problem with DataPacks
 
you forgot to reset the pack. Also your passing a handle to a native expecting client index, I'm assuming you meant to use the variable client instead of data.

Here's how to fix that issue:
Code:
public MenuHandler(Handle:menu, MenuAction:action, param1, param2)
{
        if (action == MenuAction_Select)
        {
                new Handle:data = CreateDataPack();
                WritePackCell(data, GetClientUserId(param1));
                SQL_TQuery(db, CheckDB "some query", data);
        }
}

public CheckDB (Handle:owner, Handle:hndl, const String:error[], any:data)
{
        ResetPack(data);
        new client = GetClientOfUserId(ReadPackCell(data));
        CloseHandle(data);
        PrintToChat(client, "test");
}
IF that's the only variable you're wanting to pass through, just pass that alone: (You probably already know this but It can help others)
Code:
public MenuHandler(Handle:menu, MenuAction:action, param1, param2)
{
        if (action == MenuAction_Select)
        {
                SQL_TQuery(db, CheckDB "some query", GetClientUserid(param1));
        }
}

public CheckDB (Handle:owner, Handle:hndl, const String:error[], any:data)
{
        new client = GetClientOfUserId(data);
        PrintToChat(client, "test");
}

Re: Problem with DataPacks
 
As a general rule, I do ResetPack as soon as I write the last data value. That way, even if you forget to ResetPack before reading, you've already reset it.

During a Threaded Query, the response time isn't instant so in that situation, It's best to get the client user ID and and revert it back on the other end just in case the client disconnects during the query.
