I was wondering if anyone could help me figure out where I am screwing up! I'm trying to write a really simple class that gets a MySQL resource link AND selects the proper database. In a separate definitions file I call the constructor and populate the new object's fileds. Then, in the actual working file, I include the definitions file. The MySQL error tells me that the resource link is invalid, and I don't know why. First, the class: [code]class DataConnection{ var $hostname; var $username; var $password; var $database; var $datalink; function setHostname($pV){ $this->hostname = $pV; } function getHostname(){ return $this->hostname; } function setUsername($pV){ $this->username = $pV; } function getUsername(){ return $this->username; } function setPassword($pV){ $this->password = $pV; } function getPassword(){ return $this->password; } function setDatabase($pV){ $this->database = $pV; } function getDatabase(){ return $this->database; } function setDatalink($pV){ $this->datalink = $pV; } function getDatalink(){ return $this->datalink; } function DataConnection($pV1,$pV2,$pV3,$pV4){ $this->hostname = $pV1; $this->username = $pV2; $this->password = $pV3; $this->database = $pV4; $this->datalink = mysql_pconnect($this->hostname,$this->username,$this->password); if(!$this->datalink){ return 0; } else if(!mysql_select_db($this->database,$this->datalink)){ return 0; } else return $this->datalink; } }[/code] Then, the definitions file (values deleted): [code]include "DataConnection.php"; function getDatalink(){ if($_SERVER['WINDIR']){ $db_link = new DataConnection("","","",""); return $db_link; } if(!$_SERVER['WINDIR']){ $db_link = new DataConnection("","","",""); return $db_link; } }[/code] Finally, part of the working document: [code]require_once('../inc/DataConnection.php'); session_start(); $query_myResult = "SELECT * FROM rickhomepage WHERE pageNumber = 1"; $myResult = mysql_query($query_myResult, $datalink) or die(mysql_error()); $row_myResult = mysql_fetch_assoc($myResult); $totalRows_myResult = mysql_num_rows($myResult);[/code] Any help would be appreciated!
