Programatically create multiple CCK fields in a module

Hello (my first post on drupal.org :) )
i've got exactly the same question, trying to figure out how to do it,
i've been "googling" it and found this thread interesting http://www.poplarware.com/articles/cck_field_module
hope it helps

something like this perhaps ?

function your_module_name_enable() { 
   // Get the files content
   $filename = drupal_get_path('module','your_module_name') . "/your_module_cck_export_file.cck";
  $content = implode ('', file ($filename));
  
   // Build form state
    $form_state = array(
       'values' => array(
            'type_name' => '<create>',
            'macro' => $content,
      ),
     );

   // Put it in there
     drupal_execute("content_copy_import_form", $form_state);

}

put the code above in the .install file, and create your_module_cck_export_file.cck file with the content from exported cck fields

you can export the cck fields then copy paste the content to the your_module_cck_export_file.cck.

Sample of .cck file

$content['type']  = array (
  'name' => 'my content type',
  'type' => 'my content type',
  'description' => 'my content type',
  'title_label' => 'Title',
  'body_label' => 'Body',
  'min_word_count' => '0',
  'help' => '',
  'node_options' => 
  array (
    'status' => true,
    'promote' => false,
    'sticky' => false,
    'revision' => false,
    'moderate' => false,
  ),
  'language_content_type' => '0',
  'upload' => '1',
  'addthis_nodetype' => 1,
  'old_type' => 'orchid_event',
  'orig_type' => '',
  'module' => 'node',
  'custom' => '1',
  'modified' => '1',
  'locked' => '0',
);
$content['fields']  = array (
  0 => 
  array (
    'label' => 'Event Host',
    'field_name' => 'field_host',
    'type' => 'text',
    'widget_type' => 'text_textfield',
    'change' => 'Change basic information',
    'weight' => '3',
    'rows' => 5,
    'size' => '60',
    'description' => '',

Hi Everyone,

I've been reading about how I can programmatically create a content type with cck fields. But, most of the solutions only create one particular content type on module_enable() ... just like above... But, what if I want to let the user pick the structure of the content type, based on a pre-defined set of fields. So, we could create several different content_types... as the user sees fit... also, for them to be able to add or remove fields later.. or maybe later define a field as "Required"

...most of the examples I've seen use the .cck export files... I suppose, since I only have 7 different fields they can pick from, (name, address, city, etc) then I could create a seperate file for each specific field. Then, ... ?

I fear I might have to go through the entire cck module and deconstruct it and call specific functions based on what I want to do with the dynamic content types.

...any tips on programmatically adding, removing, or changing the cck fields?
