How to comma-separate multiple values from a CCK field?

Is there a div wrapper around the list? Is it set with LI tags? If so, you can use CSS to collapse the list, but that won't put the and in it.

As for doing the list programatically, take a look at the examples at http://us.php.net/manual/en/function.implode.php. Especially the comment from "richard at happymango dot me dot uk".

If it helps somebody, below is the code which solves this problem:

1. you need to rewrite content.css value in your theme:

   .field .field-label-inline {
     visibility:visible;
   }
   

2. Follow readme instructions in cck/theme, create your field.tpl.php and insert there this code:
   

   <?php if (!$field_empty) : ?>
   <div class="field field-type-<?php print $field_type_css ?> field-<?php print $field_name_css ?>">
     <?php if ($label_display == 'above') : ?>
       <div class="field-label"><?php print $label ?>:&nbsp;</div>
     <?php endif;?>
     <div class="field-items">
       <?php $buffarray = array();
              foreach ($items as $delta => $item) :
               if (!empty($item['view']) || $item['view'] === "0") : 
                 $buffarray[] = $item['view'];
                   if ($delta == count($items) - 1) { ?>
                     <div class="field-item">
                       <?php if ($label_display == 'inline') { ?>
                         <div class="field-label-inline"><?php print $label ?>:&nbsp;</div>
                       <?php }
                       if (count($buffarray) > 1) { print implode(', ', $buffarray); } else {
                         print $buffarray[0]; 
                       } ?>
                     </div>
                   <?php } ?> 
         <?php endif;
             endforeach;?>
     </div>
   </div>
   <?php endif; ?>
   

Results:

1. "Inline" mode -
   Animals: Dog, Cat, Hamster, Rabbit
2. "Above" mode -
   Animals:
   Dog, Cat, Hamster, Rabbit

If tried to do it your way, but finally i tried to return to the basics (i had some problems with the implode2 function). I hope it can also help you.

<?php
$puntuacion = "";
$i = 0;
foreach ((array)$field_proyectos_otrosmiembros as $item) { 
$i = $i+1;
if ($i < count($field_proyectos_otrosmiembros)) { $puntuacion = ", "; } else { $puntuacion = ". "; }
print $item['view'].''.$puntuacion.' ';
}; 
?>

Thanks u all for the help in the forum!
