I need the safe output of a key from a select list field within a field collection item.

I'm theming a field collection item and one of the fields is a select list like:

icon-map|Map
icon-info|Info
icon-pencil|Pencil

I'm using the following to create some easy to use variables;

$fields = array_keys($content);
foreach ($fields as $field) {
  $field_items = field_get_items('field_collection_item', $content[$field]['#object'], $field);
  $$field = render(field_view_value('field_collection_item', $content[$field]['#object'], $field, $field_items[0]));
}

This works fine for all fields except for the select list. I need the key of that select list. For this select list field, $field_items is an array which looks like:

array(1) { [0]=> &array(1) { ["value"]=> string(13) "icon-map" } }

However, $field_icon (result of $$field = render(..) ) is Map, which makes sense.

I can get the key by using $field_items[0]['value'] but I'm not sure that's the best way.

I hope this may help

 $key = $form_state['values']['whatever'];
$options = list_allowed_values("field_whatever");
$value = $options[$key];

  • This is right, but it's possible for it not to work (if the allowed values have been altered in the form, list_allowed_values won't bring back the same as what was presented to the user, for example). In that case you could also check $form['whatever']['#options'], assuming you're in a validate/submit handler

  • else use this method , $items = field_get_items('node', $node, 'field_list'); $key = $items[0]['value']; If you need to match those up again at any point you can get the full key/value list from the field metadata: $info = field_info_field('field_list'); $values = $info['settings']['allowed_values']; $label = $values[$key];

  • Same problem with that method @user3783391 - you get the settings for the field, not necessarily what was actually used in the form

    then in that case I suppose wat @Chris Rockwell has given $field_items[0]['value'] is the right choice to get the key.
