JPGraph/PHP/mySQL class

[argusvdm]

Hello all!

I have a problem using my own (mySQL) database classes with JPGraph http://www.aditus.nu/jpgraph/...

Situation:

• Configuration:

  • Windows 2000 Pro
  • Apache 2
  • PHP/mySQL

• config.php file:

    <?php
      $db = new mysql_actions;
      $db->host = "localhost";
      $db->dbase = "***";
      $db->username = "***";
      $db->password = "***";
      $db->connect();
  
      // mySQL database class
      class mysql_actions {
        var $host;
        var $dbase;
        var $username;
        var $password;
        var $CatParent;
        var $sql;
  
        function connect() {
          $host = $this->host;
          $user = $this->username;
          $pass = $this->password;
          $dbase = $this->dbase;
          $this->conn = mysql_connect($host,$user,$pass);
          mysql_select_db($dbase) or die ("error...");
        }
  
        function query($stmt) {
          $ret = mysql_query($stmt,$this->conn);
          return $ret;
        }
  
        function fetch_object($ret) {
          return mysql_fetch_object($ret);
        }
    }
    ?>
    

• main index.php file:

    <?php
      include ("./include/config.php");
    ?>
    ..
    ..
    etc...
  

• file graph.php

    <?php
      include ("jpgraph.php");
      include ("jpgraph_bar.php");
  
      $sql = "select * from database where blabla = 'xxx'";
      $result = $db->query($sql);
      $record = $db->fetch_object($result);
  
      $datay = array($record->field1,....,....,...);
  
      $graph = new Graph($width,$height);	
      $graph->SetScale("textlin");
        ...
        ...
        ...
      $graph->Add($bplot);
      $graph->StrokeCSIM("./include/stats/graph.php","graph");
    ?>
  

This doesn't work... 🙁

Creating the graph without use of my db classes (so with ex. $result=mysql_query($sql) etc....) does work well.... but I want to use my 'old' classes...

I've read http://www.aditus.nu/jpgraph/jpg_phpoo.php, but I don't really understand how I have to implement this in my db-class so that it works...

Can anyone help?????
