Node import and domain access

If you are using Node import 1.x-rc4 or below with Domain Access, you can get this error on each row to be imported:

An illegal choice has been detected. Please contact the site administrator.

This error in this case is presented when Domain Access try to import a node without assigning it to a domain. Node import 1.x-rc4 and below  lacks Domain Access support on 1.x-rc4.

Domain Access support will be available on Node import by 1.0 RC5 version, you have to dowload the -dev version to have it now.

After that, the error should disappear. For more information, read the first lines of node_import/node_import.inc , where this error is explained.

Theme a multiple CCK field with a table

Sometimes CCK contrib modules cannot do exactly what you want. It’s time to build your custom CCK field!

Official documentation on CCK fields creation for Drupal 6 is incomplete and some passages are obscure. If there is a good howto you have to read before do any CCK customization, this is Creating Custom CCK Fields. This howto supposes you’ve read and understand it before continue. If you want to create a custom field, you can read the complete Creating a Compound field. A custom multiple compound field (with more than one field for element, e.g. an image and its description).

Read these howto well, you’ll spare time later

Well, you have followed the howto, you have your own compound field but now you have a problem. You want to display compound field data as cells in a table, and each field as row.

On following example, we have a name list made with a multiple compound field with “firstname” and “lastname” columns.

KarenS tell you that you’ve to use CONTENT_HANDLE_MODULE instead of CONTENT_HANDLE_CORE on hook_formatter_info() .

// The machine name of the formatter.
function my_funny_module_field_formatter_info() {
  return array(
    'default' => array(
      'label' => t('Default'),
      // An array of the field types this formatter
      // can be used on.
      'field types' => array('examplefield'),
      // CONTENT_HANDLE_CORE:   CCK will pass the formatter
      // a single value.
      // CONTENT_HANDLE_MODULE: CCK will pass the formatter
      // an array of all the values. None of CCK's core
      // formatters use multiple values, that is an option
      // available to other modules that want it.
      'multiple values' => CONTENT_HANDLE_MODULE,
    ),
  );
}

/** Set the formatter **/
function my_funny_module_theme() {
  return array(
    'my_funny_module_formatter_default' => array(
      'arguments' => array('element' => NULL),
      'function' => 'funny_display_table',
    ),
  );
}

/** Here you format your table data as array **/
function my_funny_module_formatter_default($element) {
  $data = array(
      $element['#item']['firstname'],
      $element['#item']['lastname'],
  );
  return $data;
}

/** This function will display a table even where data array is empty:
 ** You have to put an additional control statement to avoid this.
 ** $element will have $data from formatter_default() above
 **/
function my_funny_module_display_table($element) {
  $header = array(
    t('First name'),
    t('Last name'),
  );
  $i = 0;
  while (!$end) {
    /** Any row will contains **/
    if(array_key_exists($i, $element)) {
      $rows[] = array(
        'firstname' => $element[$i]['#item']['firstname'],
        'lastname' =>$element[$i]['#item']['lastname'],
      );
      $i++;
    }
    else {
      $end = TRUE;
    }
  }
  /** Theme a table with data from element and header **/
  return theme('table', $header, $rows);
}

Note: to format a table you have to change only “multiple values” on my_funny_module_field_formatter_info(): you can leave my_funny_module_widget_info() as is.
