Question

I know this has been asked before, and I’ve looked through every answer posted, but to no avail. Basically, I am trying to extend the Codeigniter form validation library on a CI2+ project, but every single time I get the error:

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

Below is my code:

application/core/CB_Form_validation.php

class CB_Form_validation extends CI_Form_validation{
    function __construct($rules = array()) {
        parent::__construct($rules);
        log_message('debug', "CB_Form_validaiton class initialized");
    }

    public function get_errors_array() {
        return $this->_error_array;
    }
}

and then in my ajax file I have the construct etc.

public function save(){
    if($this->form_validation->run() == FALSE){

    }
}

and inside that if statement I have tried the following:

echo $this->form_validation->get_errors_array();
echo $this->cb_form_validation->get_errors_array();
echo get_errors_array();

I have also tried placing the CB_Form_validation.php in application/libraries as well. Just as well, I have also tried this in my construct of my ajax controller

$this->load->library('CB_Form_validation');
$this->load->library('core/CB_Form_validation');

And I have set CB_ as my custom class prefix

Turns out that to fix this, you should do the following:

1. Move your custom form validation class to the application/libraries folder
2. You can keep the construct of your custom class how it is
3. Use $this->form_validation->method() to access the function you would like
4. As long as your loading the form_validation library, you don’t need to perform $this->load->library('custom_class') because CI picks up on your custom prefix anyways

Hope this helps someone
