content_taxonomy - make it comma seperated list

Hi!
yes, if you want your own theming, you have to override the default in a template file.

another possible solution;

http://drupal.org/node/167255

override in template.php (Drupal 6, actual version of content taxonomy)

/**
 * OVERRIDE Theme function for 'default' text field formatter.
 */
function yourthemename_content_taxonomy_formatter_default($element) {
  if (!empty($element['#item']['value'])) {
    $term = taxonomy_get_term($element['#item']['value']);
    _content_taxonomy_localize_term($term);
    $custom_content_tax = check_plain($term->name).'<span class="custom_comma_seperated">, </span>';
    return $custom_content_tax;
  }
}

now, you will get a comma after every term.

To do not display the last comma => add this to your css file: (I am not a php coder- i don't know another way, but there is one)

.field-type-content-taxonomy .field-item:last-child .custom_comma_seperated {
    display:none;} 

this applies to latest drupal 6 as of today, ive just copied the function from the module and added the $last variable and used it in the return

/**
 * Theme function for 'link' text field formatter.
 */
function SITETHEMENAMEHERE_content_taxonomy_formatter_link($element) {
  if (!empty($element['#item']['value'])) {
    $last = $element['#item']['#delta'] + 1 == count($element['#node']->$element['#field_name']);
    $term = taxonomy_get_term($element['#item']['value']);
    _content_taxonomy_localize_term($term);
    return l($term->name, taxonomy_term_path($term), array('attributes' => array('rel' => 'tag', 'title' => $term->description))) . ($last ? '' : ', ');
  }
}

p.s. handles not placing a comma for the 'last' element, this is a theme override in template.php, use it from your custom theme..

Looks great, seems great, great idea, but....I can't get it to work. Bah! Can the $last variable really used in this context?

Ok, I realize now that my previous comment may not have made much sense.

If I print the code count($element['#node']->$element['#field_name']); I get 0's for every element. And when I print_r($element) I wonder how count could be useful, since it is one of everything.

I'm depressed I have spent so long on this issue, but it isn't an optional requirement for me. Ah the life of a developer.

Subscribe and set do D6, which is where the last comments are about. How to get a bullit list of terms?
greetings, Martijn

Well, I officially have the lamest solution ever to this problem.

Step 1:
In the PHP from step 5, add a span with class "commaKiller"

    return check_plain($term->name) . '<span class="commaKiller">' . ($last ? '' : ', ') . '</span>';

Step 2:
Just before the end of the body tag in page.tpl.php, include the following code:

<script type="text/javascript">
	/* Comma Killer */
	$(".field-content .field-item:last-child .commaKiller").css("display","none");
</script>

There you have it. It works!

@trevorjfitz - you are using this from template.php in the site's active frontend theme right? not in a module
last time i used this (when i posted it) it worked fine.. maybe content taxonomy changed something in its theme_ function..
$last is a boolean deciding if this is the last printed element, i dont remember why it looks so cthulhian but it should make sense if you var_dump stuff there and content taxonomy DIDNT change something.. ->$element['#field_name'] is evaluated to a string like ->($[..]) http://php.net/manual/en/language.operators.precedence.php
