It might be most appropriate to talk to you freelance developer and have them update your system.

Perhaps they could also create some documentation too. That might help into the future.

Your project uses the Grocery CRUD library. You will probably find the answer in the documentation : http://www.grocerycrud.com/

Thank you for your answers.

@Chroma our dev quite the Job. No help no Doku...

@includebeer we will take a look there, Thank you very mutch

i take a look, and found it have to work by

Code:

callback

so i try and try and now it work´s.

i write a new functions

PHP Code:

function modified_edit_by($post_array, $primary_key) {
        $post_array['edit_by'] = $this->session->userdata('name');
        return $post_array;
    } 


and add the fields

PHP Code:

$crud->change_field_type('edit_by','invisible'); 


PHP Code:

$crud->callback_before_update(array($this,'modified_edit_by')); 


i need a bit to found out that "name" is the session value for username. But i look in the headercode of my headerview and found it.

Thank you for helping.
