Set default value for taxonomy list using form_alter how do I Set default value for taxonomy list?
I have tried altering form with the following line included, but it didn't work:

$form['taxonomy'][3]['#default_value'] = 6;


3 is my VOC ID and 6 TID that I want to select as default
If you are using hook_form_alter I believe this will work

$form['taxonomy'][3]['#default_value'] = array(0 =&gt; 6);
