Add Fields to Field Group programatically

Question

I have used "Field Group" module and created some groups in backend. Now i want to programatically add a field to the group. How can I do that.

I am using Hook_form_alter, I have noticed that every field has an 'und'attribute in which the field group it belongs to is listed, but if a create and 'und' array and add a field group name to it, it does not work.

How should I do it?

Answer 1

This is a bit old, but I wanted to do the same thing and couldn't find an answer on the web. I ended up figuring it out by myself.

Let's suppose you created a field group through the CMS interface with the name "group_product_fields". You added some fields to that group.

Now you have a new field being included in the form programatically via hook_form_alter. You want to add that field to "group_product_fields". Here is an example of what the field could be:

$form['new_product_field'] = array(
  '#type' => 'textfield',
  '#title' => t('New product field'),
  '#description' => t('Description for this new product field'),
);

All you need to do now is to add that new field to the field group. To do that add the line below to the hook_form_alter. It can be placed anywhere inside it.

$form['#group_children']['new_product_field'] = 'group_product_fields';

That's all. You may wish to adjust the field weight for it to be positioned as you want. But in the end this is really simple. :)

Quoting after Programtically add fields to a field group:

$groups = field_group_read_groups(array(
  'entity_type' => 'node',
  'bundle'      => 'article',
  'mode'   => 'full'
));
$your_group = $groups['node']['article']['form']['group_your_group'];
$your_group->children[] = 'field_your_new_field';
field_group_group_save($your_group);

Answer 3

Not sure how it worked for you. Because array key name must match with database field name. And They are:

| entity_type | varchar(32)
| bundle | varchar(128)

| mode | varchar(128)

I have to use following format to get it working. let me know if i am doing something silly here.

$groups = field_group_read_groups(array(
  'entity_type' => 'node',
  'bundle' => 'bundle type',
  'mode' => 'view_mode_name'));

Answer 4

Take a look at hook_field_group_build_pre_render_alter().

This provides you with an opportunity to change the structure of your groups programmatically.

For example, move the field "example_field" into the group "group_example" from the root form element:

function EXAMPLE_forms_field_group_build_pre_render_alter(&$form) {
  if (example_condition()) {
    $form['group_example'] = $form['group_example']['example_field'];
    unset($form['example_field']);
    // Further adjustments as necessary
  }
}

First, find your field group machine name in the CMS panel then in your form alter do

$form['#group_children']['FIELD_MACHINE_NAME'] = 'GROUP_MACHINE_NAME';

for an instanst, I've added a custom field mail into the User form field group field group :

$form['#group_children']['mail'] = 'group_user_form_field_group';
