[development] Array of fields on an admin settings form

[Jeff Greenberg]

Hi. I have an admin settings form that contains an array of select 
fields. The problem is that when submitted, the values don't end up in 
the db and are the select fields go back to having no selected value. 
The form was working fine as checkboxes, but when the need arose for 
each label value to have multiple values to choose from (instead of 
on/off) and I made it an array of fields, as below, it stopped working.


$results_tabs = array('' => 'None','a','b','c','d');

$form['myform']['form_text'] = array(
     '#value' => t('Select a setting for each type'),
);
$form['myform']['myform_types'] = array('#tree' => 1);
   foreach(myform_list_content_types() as $i => $type) {
     $form['myform']['myform_types'][$type] = array(
       '#type' => 'select',
       '#title' => t($type),
       '#options' => $results_tabs,
       '#default_value' => $edit['myform']['myform_types'][$i]
     );
   }
   return system_settings_form($form);
