function fetch() on a non-object problem
- by shin
I have this url,
http://webworks.net/ww.incs/forgotten-password-verification.php?verification_code=974bf747124c69f12ae3b36afcaccc68&[email protected]&redirect=/ww.admin/index.php
And this gives the following error.
Fatal error: Call to a member function fetch() on a non-object in
/var/www/webworks/ww.incs/basics.php on line 23

The forgotten-password-verification.php
require 'login-libs.php';
login_check_is_email_provided();
// check that a verification code was provided
if(
!isset($_REQUEST['verification_code']) || $_REQUEST['verification_code']==''

login_redirect($url,'novalidation');
}
// check that the email/verification code combination matches a row in the user table
// $password=md5($_REQUEST['email'].'|'.$_REQUEST['password']);
$r=dbRow('select * from user_accounts where
email="'.addslashes($_REQUEST['email']).'" and
verification_code="'.$_REQUEST['verification_code'].'" and active'
);
if($r==false){
login_redirect($url,'validationfailed');
}
// success! set the session variable, then redirect
$_SESSION['userdata']=$r;
$groups=json_decode($r['groups']);

foreach($groups as $g)$_SESSION['userdata']['groups'][$g]=true;
if($r['extras']=='')$r['extras']='[]';
$_SESSION['userdata']['extras']=json_decode($r['extras']);
login_redirect($url);
And login-libs,
require 'basics.php';
$url='/';
$err=0;
function login_redirect($url,$msg='success'){
if($msg)$url.='?login_msg='.$msg;
header('Location: '.$url);
echo '<a href="'.htmlspecialchars($url).'">redirect</a>';
exit;
}
// set up the redirect
if(isset($_REQUEST['redirect'])){
$url=preg_replace('/[\?\&].*/','',$_REQUEST['redirect']);

}
// check that the email address is provided and valid
function login_check_is_email_provided(){

$_REQUEST["recaptcha_challenge_field"],
$_REQUEST["recaptcha_response_field"]
);
if(!$resp->is_valid){
login_redirect($GLOBALS['url'],'invalidcaptcha');
}
}
basics.php is,
session_start();
function __autoload($name) {
require $name . '.php';
}
function dbInit(){
if(isset($GLOBALS['db']))return $GLOBALS['db'];
global $DBVARS;
$db=new PDO('mysql:host='.$DBVARS['hostname'].';dbname='.$DBVARS['db_name'],$DBVARS['username'],$DBVARS['password']);
$db->query('SET NAMES utf8');
$db->num_queries=0;
$GLOBALS['db']=$db;
return $db;
}
function dbQuery($query){
$db=dbInit();
$q=$db->query($query);
$db->num_queries++;
return $q;
}
function dbRow($query) {
$q = dbQuery($query);
return $q->fetch(PDO::FETCH_ASSOC);
}
define('SCRIPTBASE', $_SERVER['DOCUMENT_ROOT'] . '/');
require SCRIPTBASE . '.private/config.php';
if(!defined('CONFIG_FILE'))define('CONFIG_FILE',SCRIPTBASE.'.private/config.php');
set_include_path(SCRIPTBASE.'ww.php_classes'.PATH_SEPARATOR.get_include_path());
I am not sure how to solve the problem. Any help will be appreciated.
Thanks in advance.
