Automatically select term when only one term is available [#311694]

Hi,
for a type of content, the numbers of options in a selectBox are determined by Taxonomy Acess Control.
for a particular group the selectBox had only one option.

Is possibile to automatically preselect that value?

thanks

This is an issue that extends beyond the scope of TAC (See #180109: Only taxonomy term selected by default when there is only one)

I'm inclined to wait for that issue to be resolved before deciding what to do within TAC.

For my own sites where this issue is a problem, I've create a simple module with the following code:

/**
 * Implementation of hook_form_alter().
 */
function taxonomy_default_form_alter(&$form, $form_state, $form_id) {
  if ($form['taxonomy']) {
    foreach (array_keys($form['taxonomy']) as $vid) {
      if ($form['taxonomy'][$vid]['#required'] && 0 == count($form['taxonomy'][$vid]['#default_value'])) {
        if ($form['taxonomy'][$vid]['#options'][0]) {
          $term_keys = array_keys($form['taxonomy'][$vid]['#options'][0]->option);
          $form['taxonomy'][$vid]['#default_value'] = $term_keys[0];
        }
      }
    }
  }
}

It seems to work.

I should explain that this code will set the first (or only, if there is just one) item as the default selection (where no default selection exists) for only required fields.
