 Hi,

I'm having some problems with getting and displaying information from a mysql table. What i want to do is have it connect to the database, read name, race, class and online from the table character and then output all the names that have a value of 1 in the online column. This is however proving quite difficult for a novice php/mysql programmer. I have attached my two files that im using for the module, i have also setup mysql in the bot.conf file and i am assuming it connects.

Any help on this topic will be much appreciated.

Cheers

mangos.php
Code

<?php

class mangos extends module {

    public $title = "MaNGOS PHP IRC";
    public $author = "mielie69";
    public $version = "0.01";

    public function online($line, $args)
    {
        $channel = $line['to'];

        if ($channel == $this->ircClass->getNick())
        {
            return;
        }

        if ($args['nargs'] == 0)
        {    
            // $OnlineResult = $this->db->query("SELECT name, race, class FROM 'character' WHERE online=1");
            $this->ircClass->notice($line['fromNick'], "Players Online:");
            $noticetxt = "";
            while ($online = $this->db->query("SELECT name, race, class FROM 'character' WHERE online=1"))
            {
                $noticetxt .= $online['name'] . ": " . $online['race'] . " " . $online['class'];
                $this->ircClass->notice($line['fromNick'], $noticetxt);
            }
            $this->ircClass->notice($line['fromNick'], "End of results.");
        }
    }
}
?>


mangos.conf
Code

file mangos    modules/mangos/mangos.php

priv    !online    true    true    true    0    mangos    online


P.S I have included the file in the function.php file as well

 I think you got a little confused there... ;)

This should work a little better

Code
        if ($args['nargs'] == 0)
        {   
            // Query the database 
            $OnlineResult = $this->db->query("SELECT name, race, class FROM 'character' WHERE online=1");
            $this->ircClass->notice($line['fromNick'], "Players Online:");
            // Get the results
            while ($online = $this->db->fetchArray($OnlineResult))
            {
                // Build and send the reply
                $noticetxt = $online['name'] . ": " . $online['race'] . " " . $online['class'];
                $this->ircClass->notice($line['fromNick'], $noticetxt);
            }
            $this->ircClass->notice($line['fromNick'], "End of results.");
        }

 you see this line:
while ($online = $this->db->fetchArray($OnlineResult))

You should probably check the number of rows returned with $this->db->numRows($OnlineResult);. If that's greater than zero, then you can use the fetchArray etc...

 Sounds to me like either the query is failing or you're not properly connected to the database.

You could try the following:
Code
        if ($args['nargs'] == 0)
        {   
            // Query the database 
            $OnlineResult = $this->db->query("SELECT name, race, class FROM 'character' WHERE online=1");

            // Check if the query failed
            if ($OnlineResult === FALSE) {
               $this->ircClass->notice($line['fromNick'], 'DB ERROR: '.$this->db->getError());
            // No users are online
            } else if ($this->db->numRows($OnlineResult) == 0) {
               $this->ircClass->notice($line['fromNick'], "No Players Online");
            // 1 or more users online
            } else {
               $this->ircClass->notice($line['fromNick'], "Players Online:");
               // Get the results
               while ($online = $this->db->fetchArray($OnlineResult))
               {
                   // Build and send the reply
                   $noticetxt = $online['name'] . ": " . $online['race'] . " " . $online['class'];
                   $this->ircClass->notice($line['fromNick'], $noticetxt);
               }
               $this->ircClass->notice($line['fromNick'], "End of results.");
            }
        }

 Well all i can say is thank you so much, that error statement helped alot, there was an error in my query, i was just calling <table> instead of <dbase>.<table>, after changing that it works like a charm.

Thank you again for all the help, its much appreciated.

Cheers
