Get values from a multi value field?

Question

I have a field that can accept unlimited values. I want to print those values in my template.

The array that I can see with the devel module looks like this....

Array
(
    [und] => Array
        (
            [0] => Array
                (
                    [value] => Dustin
                    [format] => 
                    [safe_value] => Dustin
                )

            [1] => Array
                (
                    [value] => Jen
                    [format] => 
                    [safe_value] => Jen
                )

            [2] => Array
                (
                    [value] => Mike
                    [format] => 
                    [safe_value] => Mike
                )

        )

)

What I'd like to do is have these values printed to a comma separated list like: Dustin, Jen, Mike

I've been using this code to print single value fields in my template but that of course isn't going to work well with a multi value field..

<?php echo $entityform->field_team_name['und'][0]['value']; ?>

Answer 1

field_get_items() will do the trick:

if ( ($items = field_get_items('entityform', $entityform, 'field_team_name')) ) {
  $values = array_map($items, function($x) { return $x['safe_value']; });
  $comma_separated = implode(', ', $values);
}
