Question

How can I get all options for a fields?

For example, There is a field with 3 options in allowed values, like option1, option2, option3.Is there any function which receive the field name and returns selected values not a keys ?

With this just return key of selected opinion

  print ($node->field_opinion['und'][0]['value'])

Answer 1

You can do this using list_allowed_values function :

 $key = $node->field_opinion['und'][0]['value']; $options = list_allowed_values('field_opinion'); $label = $options[$key]; 

Answer 2

The accepted answer did not work for my use case, I had to do the following:

$key = // db_select('node'...
$field_definition = field_info_field('field_name');
$options = list_allowed_values(field_definition, 'node');
$label = $options[$key];
