Custom taxonomy

Just one more time. Does your code accomodates multiple dropdown.
I cloned it one for “status” and one for “property type”. When i click the update button, only “property type” works and “status” stops working.

Yap. Ive done that already. Still does not work.

For Property

add_action('admin_head', 'remove_property_taxonomy_box');
function remove_property_taxonomy_box(){

	remove_meta_box('tagsdiv-sector', 'listings', 'side');

}

if(current_user_can('manage_categories')) :

	add_action('admin_menu', 'add_property_dropdown');

	add_action('save_post', 'save_property_data');

endif;

function add_property_dropdown(){

	add_meta_box('property-dropdown', __('Property Type'), 'do_property_dropdown', 'listings', 'side', 'core');

}

function do_property_dropdown(){

	global $post;

	echo '<input type="hidden" name="taxonomy_noncename" id="taxonomy_noncename" value="'.wp_create_nonce('taxonomy_pt').'" />';

	$properties = get_terms('property_type', 'hide_empty=0');

	$property_selected = wp_get_object_terms($post->ID, 'property_type');

	$dropdown = "\n\n".'<select style="width: 180px; height: 200px;" name="prop_type[]" id="prop_type" multiple="multiple">'."\n";
	foreach($properties as $property) :
		$selected = (!is_wp_error($property_selected) && !empty($property_selected) && !strcmp($property->slug, $property_selected[0]->slug)) ? ' selected="true"' : false;
		$dropdown.= "\t".'<option id="property-'.$property->term_id.'" value="'.$property->slug.'"'.$selected.'>'.$property->name .'</option>'."\n";
	endforeach;
	$dropdown.= '<select name="prop_type" id="prop_type">'."\n\n";

	echo $dropdown;

}

function save_property_data($post_id) {

 	if(!wp_verify_nonce($_POST['taxonomy_noncename'], 'taxonomy_pt')) :
    	return false;
  	endif;

  	if(!current_user_can('edit_post', $post_id)) :
      	return false;
  	endif;

  	if(defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) :
    	return false;
	endif;

	$post = get_post($post_id);
	if($post->post_type === 'listings') :
		wp_set_object_terms($post_id, $_POST['prop_type'], 'property_type', true);
    endif;

	return $sector;

}

For Status

add_action('admin_head', 'remove_sectors_taxonomy_box');
function remove_sectors_taxonomy_box(){

	remove_meta_box('tagsdiv-sector', 'listings', 'side');

}

if(current_user_can('manage_categories')) :

	add_action('admin_menu', 'add_sectors_dropdown');

	add_action('save_post', 'save_sectors_data');

endif;

/**
 * Create the custom 'Sector' meta box
 */
function add_sectors_dropdown(){

	add_meta_box('sectors-dropdown', __('Status'), 'do_sectors_dropdown', 'listings', 'side', 'core');

}

/**
 * Populate the custom 'Sector' meta box
 */
function do_sectors_dropdown(){

	global $post;

	/** Create a security nonce for this dorpdown */
	echo '<input type="hidden" name="taxonomy_noncename" id="taxonomy_noncename" value="'.wp_create_nonce('taxonomy_sector').'" />';

 	/** Get all sector taxonomy terms */
	$sectors = get_terms('status', 'hide_empty=0');

	/** Get all of this object's terms that are in the 'sector' taxonomy */
	$selected_sectors = wp_get_object_terms($post->ID, 'status');

	$dropdown = "\n\n".'<select style="width: 180px; height: 200px;" name="sector[]" id="sector" multiple="multiple">'."\n";
	foreach($sectors as $sector) :
		$selected = (!is_wp_error($selected_sectors) && !empty($selected_sectors) && !strcmp($sector->slug, $selected_sectors[0]->slug)) ? ' selected="true"' : false;
		$dropdown.= "\t".'<option id="sector-'.$sector->term_id.'" value="'.$sector->slug.'"'.$selected.'>'.$sector->name .'</option>'."\n";
	endforeach;
	$dropdown.= '<select name="sector" id="sector">'."\n\n";

	echo $dropdown;

}

/**
 * Save the term that the user selects from the custom 'Sector' meta box
 *
 * @param required integer $post_id The id of the post being edited
 * @return false|string $sector The sector that the user selected
 */
function save_sectors_data($post_id) {

	/** Check the security nonce to ensure we have the proper authorisation  */
 	if(!wp_verify_nonce($_POST['taxonomy_noncename'], 'taxonomy_sector')) :
    	return false;
  	endif;

  	/** Ensure that the user has the correct permissions */
  	if(!current_user_can('edit_post', $post_id)) :
      	return false;
  	endif;

  	/** Check if this is an auto save routine. If it is our form has not been submitted, so we dont want to do anything */
  	if(defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) :
    	return false;
	endif;

  	/** Now save the data against the correct taxonomy */
	$post = get_post($post_id);
	if($post->post_type === 'listings') :
		wp_set_object_terms($post_id, $_POST['sector'], 'status', true);
    endif;

	return $sector;

}

Thanks. Works fine now.
