Array and foreach return Illegal string offset

Question

I have an array like:

array(
    'username' => array(
        'required' => true,
        'min' => 5,
        'max' => 20,
        'unique' => 'users',
        'name' => 'Username'
    )
);

This array goes into a function like (this is not the complete function):

//$source = $_POST
public function validate($source, $items = array()) {
    foreach($items as $item => $rules) {
        foreach($rules as $rule => $rule_value) {
                    //db->sanitize = mysqli_real_escape_string()
            $value = $this->db->sanitize($source[$item]);

            if($rule === 'required' && empty($value)) {
                            //The problem is here with $rule['name']
                $this->addError($rule['name'].' is empty');
            }
        }
    }
}

So I would like to use the 'name' key from the array to display a user friendly input field name but all it returns is: Warning: Illegal string offset 'name' in

Both $rule and $rule_value are strings. They are the key/value (respectively) of your $rules array. I'm guessing you want $rules['name']. — gen_Eric

if($rule === 'required' && empty($value)) {
    $this->addError($rules['name'].' is empty');
