i know how display data without using class, have been asked use mysql class instead. seems have initiate class , use written functions, whatever try display - doesn't work. getting "resource id #14", means should connection. please help!

this part of mysql class:

class sql //mysql {   var $link_id;   var $query_result;   var $num_queries = 0;    function connect($db_host, $db_username, $db_password, $db_name = '', $use_names = '', $pconnect = false, $newlink = true) {      if ($pconnect) $this->link_id = @mysql_pconnect($db_host, $db_username, $db_password);     else $this->link_id = @mysql_connect($db_host, $db_username, $db_password, $newlink);         if (!empty($use_names)) $this->query("set names '$use_names'");      if ($this->link_id){       if($db_name){         if (@mysql_select_db($db_name, $this->link_id)) return $this->link_id;           else die(mysql_error());// = "can't open database ('$db_name')";         if (!empty($use_names)) $this->query("set names '$use_names'");       }     } else die(mysql_error());// = "can't connect mysql server";   }    function db($db_name) {     if ($this->link_id){       if (@mysql_select_db($db_name, $this->link_id)) return $this->link_id;         else die(mysql_error());// = "can't open database ('$db_name')";     } else die(mysql_error());// = "can't connect database";   }    function query($sql){     $this->query_result = @mysql_query($sql, $this->link_id);      if ($this->query_result){       ++$this->num_queries;       return $this->query_result;     } else {         $error = "             <pre>                 query: \n {$sql} \n\n                 error: <span style=\"color:red\">" . mysql_error() . " </span>             </pre>         ";       die($error);     }   }   function result($query_id = 0, $row = 0, $field = null){     return ($query_id) ? @mysql_result($query_id, $row, $field) : false;   }    function fetch_row($query_id = 0){     return ($query_id) ? @mysql_fetch_row($query_id) : false;   }    function fetch_array($query_id = 0){     return ($query_id) ? @mysql_fetch_array($query_id) : false;   }    function fetch_assoc($query_id = 0){     return ($query_id) ? @mysql_fetch_assoc($query_id) : false;   }    function num_rows($query_id = 0){     return ($query_id) ? @mysql_num_rows($query_id) : false;   } ....

and php code:

<?php require_once('c:/wamp/www/smarty-3.1.21/libs/smarty.class.php'); include('c:/wamp/www/smarty-3.1.21/libs/mysql.class.php');  $smarty = new smarty(); $smarty->enablesecurity();  $smarty->settemplatedir('c:\wamp\www\forum\templates'); $smarty->setcompiledir('c:\wamp\www\forum\templates_c'); $smarty->setconfigdir('c:\wamp\www\forum\configs'); $smarty->setcachedir('c:\wamp\www\forum\cache');  $db = new sql(); $db->connect('localhost','root','','job', '', false, true);  $db->db('job'); $sql = "select * job"; $db->query($sql); $output = $db->query_result; $result = $db->fetch_row();   $smarty->assign('rez', $result); $smarty->assign('output', $output); $smarty->display('index.tpl');  ?>
