Warning: Invalid argument supplied for foreach()

[freak4]

I have this code in one of my files:

                $requiredFields = array();
                foreach ($fields as $key => $field) {
                    if (1 == $field['required']) {
                        $requiredFields[$key] = $field['message'];
                    }
                }

Getting error:

 

Warning: Invalid argument supplied for foreach() in /home/USER/public_html/register.php on line 79

 

Anybody help?

 

thank you.

It's saying that $fields is not an array when it gets to the foreach loop.
