Hi, I tried to add email as readonly field / readonly in grocery crud
in the add form, the callback is works fine

but when I click save, the callback is ignored

this is my code, is I am missing something? thanks
// the function
function tema(){
        $crud = new grocery_CRUD();
        $crud->set_table('design_theme')
             ->add_fields('theme','email')
             ->edit_fields('theme','email','status')
             ->field_type('email','readonly')
             ->display_as('theme','Tema')
             ->display_as('theme_date','Tanggal Tema')
             ->callback_add_field('email',array($this,'mail_callbacks'));
        $output = $crud->render();
        $this->kekgwpeduliaja($output);
    }
// the callback
function mail_callbacks(){
        $user = $this->ion_auth->user()->row();
        $mail = $user->email;
        return '<input type="text" id="email" name="email" value="'.$mail.'" disabled />';
    }
