You can create as many metaboxes as you want. Use a function to create them then hook into init. The first line should be $meta_boxes = array();
then start each new metabox with $meta_boxes[] = array(
add_action( 'init', 'prefix_create_metaboxes' );
function prefix_create_metaboxes() {
$meta_boxes = array();
$meta_boxes[] = array(
'id' => 'venue_location',
'title' => 'Venue/Location',
'pages' => array('post'), // post type
'context' => 'normal',
'priority' => 'high',
array(
'name' => 'Venue',
'desc' => 'Venue Name',
'id' => 'venue_info',
'type' => 'text',
'default' => ''
),
array(
'name' => 'Location',
'desc' => 'Location of the Venue',
'id' => 'location_info',
'type' => 'text',
'default' => ''
),
)
);
$meta_boxes[] = array(
'id' => 'another_meta_box',
'title' => 'Another Meta Box Title',
'pages' => array( 'post' ), // post type
'context' => 'side',
'priority' => 'low',
'show_names' => true,
'fields' => array(
array(
'name' => 'Field Name',
'desc' => 'Field Desc.',
'id' => 'field_id',
'type' => 'text'
),
)
);
}
