Hi,
I have these two tables in the database:

Subservices:
id, ..., background_id

Backgrounds:
id, filename

With grocery crud I'd like to show the background thumbnail (which is the "filename" field) in a column of subservices.

In the controller I have this:

function index()

{

	    $crud = new grocery_CRUD();

	    ...

	    $crud->columns('service_id', 'name','english_name', 'italian_text', 'english_text',

		    'background_id');

	    ...

	    $crud->set_relation('background_id', 'backgrounds', 'filename');

	    $crud->callback_column('background_id', array($this, 'show_picture_in_row'));

	    ...

}

function show_picture_in_row($id, $row)

{

  $string = '<img src="images/backgrounds/thumbs/'.$row->filename.'"   />';

  return $string;

}

It's not working. It just displays the filename, for example: picture_1.jpg

What am I doing wrong?

This is how i solved the problem. I hope it may help you

function show_picture_in_row($value, $row)

{

    $path=base_url();

    $this -> db -> where('cat_id', $row->cat_id);

	    $select = $this -> db -> get('category') -> row();

		  $string = "<img src='$path"."uploads/albumarts/table/$select->album_art'/>";

  return $string;

}
