Targeting CCK in 6 not working

Check out this issue: http://drupal.org/node/247399

Marking #270116: cannot populate cck fields as a duplicate of this. Looks like CCK changes for 6 are making this wonky.

I fixed CCK in D6 using the following patch. Not sure if this does something bad, as I really don't know how forms in D6 are handled. But var_dump() helped me finding the problem and it works for me now.

Thanks for the patch. I won't get a chance to look at this for a week or so but I'm marking it needs review and hopefully others can take it for a spin.

Perhaps I should describe what the problem was, so you don't have to find out yourself...:

I use the Prepopulate-module to fill nodereferences with initial data (other cck-fields may behave different). Within _prepopulate_get_walk() the module tries to find the last entry in $form according to the array given in $_GET. It seems like things have changed here, at least nodereference stores an array inside $field['#default_value']. So the array needs to be set right. Walking the $form-array fails, because it only tries to use the last element as a default value. Instead with the patch I checked if $form has an #default_value-item and set it using array_merge(), so the whole array gets copied into the form. I don't know if replacing the array instead of doing array_merge() would be better or if there is some better way to figure out that #default_value needs to be set (or further walking is needed). Like said before, I don't know much about drupal forms, but the patch just worked...so I thought it might be worth sharing. ;-)

Sorry, somehow the status of the ticket got changed...

On Drupal 6.3 this module works only with [title]. Body and CCK fields cannot be changed. #5 patch is ineffective on my installation.

Drupal: 6.3, CCK: 6.x-2.0-rc4

Well, It works only under some conditions.

Following tests run on a 6.x-2.x-dev (2008-Jun-24) patched with #5.

1. [taxonomy][1]=3

   <option value="2">A</option>
   <option value="3">AB</option>
   <option value="4">B</option>
   <option value="1">O</option>
   </select>
   

   Select AB option on from vocabulary 1

2. [field_references][0][value]=My%20References
   

   <textarea id="edit-field-references-0-value" class="form-textarea resizable textarea-processed" name="field_references[0][value]" rows="5" cols="60">My References</textarea>
   

   Add My References to field_references field (text field on multiple rows).
   Note: it only works outside Groups (fieldset). Moving a field outside fieldset make it works.

3. [language]=en
   

   <select id="edit-language" class="form-select" name="language">
   <option value="">Indipendente dalla lingua</option>
   <option selected="selected" value="en">Inglese</option>
   <option value="it">Italiano</option>
   </select>
   

   Select "Inglese" multilingual option (using the value as ID, like taxonomy) from Internationalization module.

4. edit[field_work][0][nid]=12

   <input id="edit-field-work-0-nid-nid" class="form-text form-autocomplete" type="text" value="Mai [nid:12]" size="60" name="field_work[0][nid][nid]" maxlength="128" autocomplete="OFF"/>
   

   To select Mai (node/12) on the first nodereference CCK field. Note: name is field_work[0][nid][nid] but only [field_work][0][nid] works.

Main issues:

• Cannot select any CCK field contained into a fieldset: moving out make they work.
• Second cck nodereference field (e.g. [field_work][1][nid]) cannot be populated.

Update: to select CCK field into fieldsets, postpone the fieldset class, replacing "-" with "_" (tested using #13 patch). e.g.:

Standard field targeting:

edit[field_surname][0][value]=Smith

Same field, into group (fieldset) named "ID":

edit[group_id][field_surname][0][value]=Smith

I hope these tests will be useful to fix these bugs.

I don't believe the patch is working for me, but I could have my URL formatted wrong too.

I want to prepopulate a CCK nodereference dropdown field. Here is the HTML for the field:

<select id="edit-field-customer-nid-nid" class="form-select required" name="field_customer[nid][nid]">

And here is what I attempted for a URL:

http://localhost/drupal-6/node/add/activity?edit[field_customer][nid][nid]=Kingdom

I'd appreciate any suggestions. :)

Try http://localhost/drupal-6/node/add/activity?edit[field_customer][0][nid]=$nid
($nid means it should be the ID, not the title)

Sometimes ddanier #5 patch on my installation causes a "warning: array_keys() [function.array-keys]: The first argument should be an array" when targeting page title. On _prepopulate_get_walk !is_null($form['#default_value']) else missed the is_array($getslice) control statement. I attach the new patch (I have to test it more deeply).

#13 works for me on a node reference field (single value, select widget). Since thats better than what we have today, I mark this RTBC. You might want to fix up a few braces before commit since they don't perfectly match coding standards.

I thought I would help out so I went ahead and fixed the patch.

Don't want to seem impatient, but I like this module and have a few projects that could benefit from it.

Yup! Thanks alot. Lost half aday because of this bug. I fixed it by myself and (idiot me) only afterwards looked at the issues queue to find this patch already exists :)

Anyways! Good job!

And... MERGE IT INTO HEAD please! :)

#15 works for me on a nodereference select widget.

Any maintainers know when we could get this rolled into a new release or dev?

I confirm patch #15 this works nicely, please commit.

Committed to 6 dev and HEAD. Thanks to all. There are some new maintainers for the project, so hopefully they will step up and start getting the code moving again.

As is stated in #10 there only can be the first value of a multiple value field pre-populated.
(Second cck nodereference field (e.g. [field_work][1][nid]) cannot be populated.)

Any ideas how to accomplish this? Just adding up the delta doesn't work. CCK seems to need a preparation of values beforehand, maybe this is of any use: _content_widget_invoke('prepare form values', $node);

I added in my _form_alter (using SESSION var instead of GET var):

...
    foreach (array_keys((array)$_SESSION['createfromweb_edit']) as $getvar) {
      if (isset($form[$getvar][1])) { // we have a multiple value field
        $fieldname = $form[$getvar][1]['#field_name'];
        $slots = count($_SESSION['createfromweb_edit'][$fieldname]);
        // prepare needed slots (copy array from first field) 
        for ($i = 1; $i<=4; $i++) {
          $form[$getvar][$i] = $form[$getvar][$i-1];
          $form[$getvar][$i]['#default_value'] = array();
        }
      }
      if (element_child($getvar) && !is_null($form[$getvar])) {
...

Then I can set multiple values via $_SESSION['createfromweb_edit'][$fieldname][$i]['value'] = trim($val);

This post was very helpful.

As a note, I was able to populate 6.X node_reference checkbox fields using:

<input id="edit-field-guides-nid-nid-18043" class="form-checkbox" type="checkbox" checked="checked" value="18043" name="field_guides[nid][nid][18043]"/>

The prepopulate URL looks like:
http://mysite/node/add/story?edit[field_guides][nid][18043]=18043

Thanks
