I'm using some hook code I got from Drupal 7 show empty fields in order to show all of the empty fields on my node when viewing it. I would like to put a simple - as the displayed value when the field is empty.
function mymodule_field_attach_view_alter(&$output, $context) { // other stuff clipped... $output[$field_name] = array( '#theme' => 'field', '#title' => $instance['label'], '#label_display' => 'inline', '#field_type' => $field['type'], '#field_name' => $field_name, '#bundle' => $node->type, '#object' => $node, '#items' => array(), '#entity_type' => 'node', '#weight' => $display['weight'], 0 => array('#markup' => '-'), ); } I pulled the code from the linked page above and just changed the one line at the end that has #markup. As far as I can tell from the api docs, this code should work, but nothing that I put into that #markup value shows up.
All of the empty fields DO show up, it's just that the value shown is empty instead of - or blah or foo, because I've tried those as well. :)
How do I set the value to display when I use hook_field_attach_view_alter?
