function workflowfield_field_prepare_view in Workflow 7.2

Implements hook_field_prepare_view().

This hook is needed in the following case:

  • Edit a node with Workflow Field;
  • Change the value of the widget;
  • Click [Preview] button;

See the "Notice: Undefined index: value in list_field_formatter_view() (line 467+472 of \modules\field\modules\list\list.module)." This is because in the Workflow Widget, the data is stored in a 'workflow' structure, not a 'value' value.

However, it is a pity that we run this hook in every view :-(

File

workflow_field/workflowfield.field.inc, line 228
Defines a Workflow field, widget and formatter. (copied from list field).

Code

function workflowfield_field_prepare_view($entity_type, $entities, $field, $instances, $langcode, &$items) {

  // I guess Preview mode is only with 1 entity at a time.
  if (count($items) !== 1) {
    return;
  }
  foreach ($items as $id => &$item_array) {
    foreach ($item_array as $index => &$item) {
      if (!isset($item['value'])) {
        $item['value'] = isset($item['workflow']['workflow_sid']) ? $item['workflow']['workflow_sid'] : '';
      }
    }
  }
}
