Meta key and Meta value in CodeIgniter

@nkhan

Like this?

Code:

function get_meta($key) {

    $row = get_instance()->db
        ->select('meta_value')
        ->from('site_settings')
        ->where('meta_key', $key)
        ->limit(1) // 'meta_key' should be unique anyway, this is just in case.
        ->get()
        ->result_array();

    return isset($row['meta_value']) ? $row['meta_value'] : null;
}

Edit: You can examine this library: https://github.com/ericbarnes/ci-settings and to make something simplified for your case.
