Set Value to a select field by its key in webform

Question

I'm trying to set a select field to one specific default value by it's key (one country, which i retrieve from another form), and then disable the field.

I implement hook_form_alter, i get the correct field inside the $form array, but, when i want to set the select field to one value, nothing happens. I'm trying this way:

 $form['#node']->webform['component'][91]['value']['#default_value'] = $country;

But, this does not work. Any guess on how i can achieved this, and if this is possible or the right way to do it?

Thanks

Answer 1

This is the way I do it and it works:

// set default value to a D7 form field
$form['FIELD_NAME']['und'][0]['value'] = $country;

// prevent user from changing the field value
$form['FIELD_NAME']['#access'] = false;

Hope this helps.
