How to post checkbox that are unchecked In CI?

Here, My html view for multiple checkbox :

Html for check box is like below

For A_I Checkbox

<input type="hidden" name="auto_number[]" id="auto_numberhidden" value="0" />
<input type="checkbox" name="auto_number[]" id="auto_number" value="1" />

For Not Display IN Form Checkbox

<input type="hidden" name="not_show_in_form[]" id="not_show_in_formhidden" value="0" />
<input type="checkbox" name="not_show_in_form[]" id="not_show_in_form" value="1" />

Here is my CI function for add table data :

if ($this->form_validation->run() == TRUE) {

            $name_col = $this->input->post('name_col');
            $type_col = $this->input->post('type_col');
            $length_values_col = $this->input->post('length_values_col');
            $index_col = $this->input->post('index_col');
            $auto_number = $this->input->post('auto_number');
            $not_show_in_form = $this->input->post('not_show_in_form');
            $createTable = $post = array();
            for ($i = 0; $i < count($name_col); $i++) {
                $createTable['fields'][] = array(
                    'name_field' => $name_col[$i],
                    'type_field' => $type_col[$i],
                    'length_field' => $length_values_col[$i],
                    'index_field' => $index_col[$i],
                    'auto_field' => $auto_number[$i],
                    'not_show_in_form' => $not_show_in_form[$i]
                );
            }
            echo '<pre>';
            print_r($createTable);die;
}

When I'm submit my form, It will give me form array like :

    Array
(
    [fields] => Array
        (
            [0] => Array
                (
                    [name_field] => id
                    [type_field] => INT
                    [length_field] => 11
                    [index_field] => PRIMARY
                    [auto_field] => 0
                    [not_show_in_form] => 0
                )

            [1] => Array
                (
                    [name_field] => name
                    [type_field] => VARCHAR
                    [length_field] => 20
                    [index_field] => 
                    [auto_field] => 1
                    [not_show_in_form] => 1
                )

            [2] => Array
                (
                    [name_field] => gender
                    [type_field] => VARCHAR
                    [length_field] => 10
                    [index_field] => 
                    [auto_field] => 0
                    [not_show_in_form] => 0
                )

            [3] => Array
                (
                    [name_field] => created_date
                    [type_field] => DATE
                    [length_field] => 
                    [index_field] => 
                    [auto_field] => 0
                    [not_show_in_form] => 0
                )

        )

)

Issue:

Here, id field have two check value i.e. A_I and Not Display IN Form and created_date have only Not Display IN Form. According to my form my array like as below, But it give me above array.

Array
(
    [fields] => Array
        (
            [0] => Array
                (
                    [name_field] => id
                    [type_field] => INT
                    [length_field] => 11
                    [index_field] => PRIMARY
                    [auto_field] => 1
                    [not_show_in_form] => 1
                )

            [1] => Array
                (
                    [name_field] => name
                    [type_field] => VARCHAR
                    [length_field] => 20
                    [index_field] => 
                    [auto_field] => 0
                    [not_show_in_form] => 0
                )

            [2] => Array
                (
                    [name_field] => gender
                    [type_field] => VARCHAR
                    [length_field] => 10
                    [index_field] => 
                    [auto_field] => 0
                    [not_show_in_form] => 0
                )

            [3] => Array
                (
                    [name_field] => created_date
                    [type_field] => DATE
                    [length_field] => 
                    [index_field] => 
                    [auto_field] => 0
                    [not_show_in_form] => 1
                )

        )

)
