Hi there,

I'm trying to do something that I was hoping would be relatively simple. My goal is just to programmatically select a single radio button in a custom CCK field.

Custom Content Type & Field

I've created a custom content type ("deposit_campaign_response") in CCK with a custom field. Here are the specs on the field:

  • Field name: field_status
  • Field type: Text
  • Widget type: Check boxes/radio buttons
  • Allowed values list:
    • 1|Yes, I will deposit.
    • 2|I'm pretty sure that I am coming.
    • 3|I'm still thinking about it. I might need some more information.
    • 4|No, I've made other plans.
    • 5|I've already submitted my deposit.

Custom Module

I've created a custom module named "dcr". Here's the code that I've tried in order to select a specific option.

First Attempt:

First, I tried just a simple use of a form-specific form_alter function, like so. (I confirmed that the function was being run on the correct form.)

function dcr_form_deposit_campaign_response_node_form_alter(&$form, &$form_state) {
  $form['field_status']['#default_value'][0]['value'] = 1;
  return $form;
}

RESULT: The widget disappears completely from the $form array, and therefore doesn't display.

Second Attempt:

Next, I tried an "#after_build" function, like so (based on http://drupal.org/node/726282):

function dcr_form_deposit_campaign_response_node_form_alter(&$form, &$form_state) {
  $form['#after_build'][] = 'dcr_after_build';
  return $form;
}

function dcr_after_build($form, &$form_state) {
  $form['field_status']['#default_value'][0]['value'] = 1;
  return $form;
}

RESULT: No change.

Other Varied Attempts:

I also tried setting the keys to the option label, like
$form['field_status']['#default_value'][0]['value'] = t('Yes, I will deposit.');

As a last ditch effort, I tried going through every "value", "#value", or "#default_value" key in both the $form and $form_state arrays, but setting that didn't seem to help. Seems like I'm missing something simple or obvious.

Any ideas as to what I'm doing wrong?!

but try making [0] into ['0']? Also I think 'value' should be '#value' but #default_value might be better.
Print out (print_r()) the contents of $form[] in your _alter function so you can see exactly what the variables are named.

I'm having the exact problem and I can't find any solution. I manage to find the places the data from the selection is stored in $form and $form_state, but changing it there didn't make any change.
So have you found a solution yet?

hi,
we can use hook_form_alter to that.

function dcr_form_alter(&$form, &$form_state, $form_id) {
  if($form_id == 'deposit_campaign_response_node_form') {
    $form['field_status']['#default_value'][0]['value'] = 1;
  }
}
