Fatal error: Call to a member function on a non-object

[M8than]

I'm trying my hand at OOP and I am stuck, I try to pass some variables to an oop class and it comes up with that error.
My Global.php:

<?php
session_start();
 
if(isset($_SERVER['HTTP_CF_CONNECTING_IP']))
{
  $_SERVER['REMOTE_ADDR'] = $_SERVER['HTTP_CF_CONNECTING_IP'];
}
 
include "includes/config.php";
include "includes/class.essentials.php";
include "includes/class.users.php";
 
 
$db_host = $config['database']['host'];
$db_username = $config['database']['username'];
$db_password = $config['database']['password'];
$db_name = $config['database']['name'];
$db_connect = mysql_connect("$db_host", "$db_username", "$db_password");
$db_select = mysql_select_db("$db_name");
if(!$db_connect){
    die("Can not connect to database!");
}
if(!$db_select){
    die("Can not select database!");
}
 
$reg = new users\REG();
$login = new users\LOGIN();
$security = new cms\SECURITY();
?>

The code that causes the error:

<?php include "global.php";?>
<?php
if (isset($_POST['register']))
{
    $password = $_POST['reg_password'];
    $password2 = $_POST['reg_rep_password'];
    $username = $_POST['reg_username'];
    $refer = $_POST['reg_refer'];
    $reg->regcheck($username, $password, $password2, $refer);
}
?>

The functions:

 public function regcheck($username, $password, $confpassword, $refer)
    {
        $errors = "";
        $username1 = $security->filter($username);
        $password1 = $security->filter($password);
        $confpassword1 = $security->filter($confpassword);
        $refer1 = $security->filter($refer);
        if ($password1 != $confpassword1)

public function filter($data)
    { 
        if(empty($data)){
            return $data;
        }
        $data = str_replace(array('&','<','>'), array('&','<','>'), $data);
        $data = preg_replace('/(&#*\w+)[\x00-\x20]+;/u', '$1;', $data);

Basically it's trying to say that the function doesn't exist.

What is with the 'users\REG();' etc?

 

[M8than]

In the global.php? It's the namespace and class.

 

[Markshall]

I've never seen it done like that before. I just do

$reg = new REG();

Not sure if you need the 'users\' but try removing it and see if that makes a difference.

Okay but do you use namespaces?

EDIT: without the namespace it comes up with Class 'REG' not found

 

[Markshall]

No lol, I just use class... because I'm class. *true story*

 

[M8than]

Class REG not found without the namespace.

In regcheck put at the top of it

global $security;

and

<?php include "global.php";?>
<?php
if (isset($_POST['register']))
{
    $password = $_POST['reg_password'];
    $password2 = $_POST['reg_rep_password'];
    $username = $_POST['reg_username'];
    $refer = $_POST['reg_refer'];
    $reg->regcheck($username, $password, $password2, $refer);
}
?>

to

<?php include "global.php"; global $reg;?>
<?php
if (isset($_POST['register']))
{
    $password = $_POST['reg_password'];
    $password2 = $_POST['reg_rep_password'];
    $username = $_POST['reg_username'];
    $refer = $_POST['reg_refer'];
    $reg->regcheck($username, $password, $password2, $refer);
}
?>
