No output even with 'display' set to true

Have you tried updating to the latest 4.7 version of cck?

pgassner, I don't think you're asking too much! The documentation in the README.txt and on the project page says this:

If this [ie. Store using the database settings below] is checked then the field is computed on node save and stored. If it isn't stored then it will be recomputed every time you view a node containing this field.

which the behavior that you, I, and this user are looking for.

I've been trying to reproduce the fix you described in #3 involving adding a _computed_field_compute_value call to the «view» hook, but so far I get duplicates of my data (one updated correctly, one not). Can you post a code snippet of the computed_field_field function? It would be helpful to me, and also might help wrunt to fix this.

and wrunt, thanks for an excellent module!!

I;'m still trying to get this to work as advertised. I'm using the version updated 27 Nov. 2006. In looking at the changelog, I find this:

29th September 2006
...
* Made non-stored computed fields compute on load, rather than view.

which would appear to directly contradict the project page as cited in #4.

Here's how I've hacked the «view» hook in computed_field.module to make non-stored fields compute on view (only one line was added):

/**
 * Implementation of cck hook_field
 */
function computed_field_field($op, &$node, $field, &$node_field, $teaser, $page) {
  switch ($op) {
...
    case 'view':
      if ($field['display']) {
        if (empty($node_field)) {
          $node_field[0]['view'] = content_format($field, $node_field[0], 'default', $node);
        }
        else {
          foreach ($node_field as $delta => $item) {
// The next line was added to make non-stored fields recompute on view
            _computed_field_compute_value($node, $field, $node_field);
            $node_field[0]['view'] =  content_format($field, $node_field[0], 'default', $node);
          }
        }
        return theme('field', $node, $field, $node_field, $teaser, $page);
      }
      break;
...
  }
}

To make this work properly, I also have to be sure that the field is cleared out before use in any computed code (ex. $node_field[0]['value'] = "";); otherwise, I get multiple copied of the computed result.

Hi,
I am having issues here as well.
I don't even get the computed field to appear in the form for creating the node (it is also not displayed in the view).
I am using drupal 5 with the latest CCK

Using Drupal 5.1, CCK 5.x-1.4 and Computed Field dated 2006-Nov-27.

No output is given in a view or edit page. It looks like no hook functions from the module are called at load or view.

I believe that this happens because the function computed_field_field_settings() does not handle correctly the case where it is called with $op='callbacks', as documented in hook_field_settings() on cck/field.php.

Patch attached.

Thanks yhager, I've added your change to cvs, but it seemed to work for me even before making the change.

Even after this patch looks like it was rolled into release 5.2 I have problems where

I use the code provided to link back to the node.
I set the field to "display raw text in the content type field settings for my given content type.
When i PREVIEW a submitted node, it WORKS, I see the link back to the node BUT
When I submit it and view the node after submittal it's GONE.

MAGIC? I opened this back up because it seems related. Strange Behavior. I am fully up to date with
Computed Field 5.x-1.2
Content Construction Kit (CCK) 5.x-1.6-1

Same here no output. no field no nothing although it pretends to be there :/

CCK 1.6 and computed field downloaded today :/

Ckicked display field did store in data base, tried to add to a group ... nothing ... :(

Try latest patch at http://drupal.org/node/134661
Works for me.

5.x is unsupported. re-open for 6.x if applicable
