Default Using PEAR DB and Classes.

PEAR DB normally works fine for me but I'm trying to write a simple dummie class to test how it works within a class. I'm currently reading PHP mySQL Website Programing: Problem - Design - Solution from Wrox so that's where I'm learning most of this stuff.. Any way let me show you the code first.

    * Handles user login.

    class session {
        var $_strUserName;
        var $_strUserPass;
        var $_objConn;
        var $_objMail;

        // Class constructor...
        function session($name=' ',$pass=' ') {
            $this->_objConn =& DB::connect(DSN);

            if($_strUserName == ' ') {
                // Ensures a username was submitted...
                $this->_error("No user name was specified.");
                return FALSE;
            } else {
                $this->_strUserName = $name;
                $this->_strUserPass = $pass;

        // Authenticates the user...
        function _authenticate() {
            $sql = "SELECT admin_id,admin_pass FROM administrators WHERE admin_name=" . $this->_strUserName;
            echo $sql;    
            $objRS = $this->_objConn->query($sql);
            $objRow = $objRS->fetchRow(DB_FETCHMODE_ASSOC);

            if($objRS->numRows() < 1) {
                $this->_error("The user name you entered does not exist.");
                return FALSE;
            } elseif($objRS['admin_pass'] != $this->_strUserPass) {
                $this->_error("The password you entered is incorrect.");
                return FALSE;
            } else {
                echo "<p><strong>CONGRATULATIONS!</strong><br/>You have successfully logged into the site as: " . $this->_strUserName . "</p>";

        // Generates an error...
        function _error($strMessage) {
            echo "<p><strong class=\"error\">ERROR you could no be logged:</strong><br>";
            echo $strMessage;
I know for a fact that the Pear object is working up to the point fetchRow is called becuase when I echo $objRS I get the response 'Object' as output. But for some reason the page generates a fatal error saying the function fetchrow is undefined... does anyone know what I can do?

Are you sure it's working? Read the manual:

quote:[i]From http://pear.php.net/manual/en/packag...ntro-query.php[i]
On failure you get a DB_Error object, check it with DB::isError(). On succes you get DB_OK or when you set a SELECT-statment a DB_Result object.
so echo $objRS doesn't tell you anything useful. It tells you that $objRS is an object -- to assume it's a valid DBResult object is a really poor assumption.

Take care,
