Drupal7: list allowed values from a field type list [SOLVED]

In Drupal 7, how do you list all the allowed values in a certain field of some content type?

You can use the list_allowed_values function.

Lets see it with an example.

I will define a new Content Type called “Actividad” (machine name=’actividad‘), which will have a title, a body and a List(text) field type called ‘tipo_actividad‘ (machine name=’field_tipo_actividad‘):

And then I will define the allowed values for this field_tipo_actividad field:

Now, how do I programmatically list the allowed values for that field? Using list_allowed_values function:

$field = field_info_field('field_tipo_actividad'); /* field_tipo_actividad=machine name of the field */
$allowed_values = list_allowed_values($field);     /* what are the values allowed for that field? */
return var_dump($allowed_values);

If you want a prettier output, you can change the code to:

$field = field_info_field('field_tipo_actividad');
$allowed_values = list_allowed_values($field);
$salida = "";
foreach ($allowed_values as $key=>$value){
    $salida = $salida."Key: ".$key." Value: ".$value."<br />";
}
return $salida;

And you’ll get something like:
