I'm working on a custom theme and googled the whole day but can't find an answer to my question:

how to print out a cck list field's key instead of its label?

I think it's the right way to access fields via the field api, right? so I try

$output = field_view_field('node', $node, 'field_list');
print render($output);

that seems to be the way to get the label value of the key|label pair. but even if i set the display options format to 'key' - it only prints the label value. what am I doing wrong?

I know there are other options to render the key but how is it possible using field api?

You can get the field value itself (which will be the allowed values array key) with field_get_items():

$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];

Here's a similar way. This example works for a Country list with ISO codes. The idea is to render the Name of the Country that was selected because the dump returns only the key ( iso code in this case)

Format of the select list on the backend:

AR|Argentina
US|United States

Assuming you have selected United States on the backend and you want to print the country name on the node template:

$country_field = field_info_field('field_country_iso');
$country_iso = $node->field_country_iso[LANGUAGE_NONE][0]['value'];
$country_name = $country_field['settings']['allowed_values'][$country_iso];

then

print $country_name; // This will return United States, not US code

I hope this helps.
