Multiple Custom Meta Boxes & Fields

(@tmw27529)

I have a Custom Post Type that has multiple Custom Meta Boxes, each with multiple Custom Fields. The code is a bit overwhelming and I wondering if there might be a better way to go about doing this.

// Add the DATE OF BIRTH and DEATH DATE Meta Box
function add_bldob_meta_box() {
    add_meta_box(
        'bldob_meta_box', // $id
        'Date of Birth and Death', // $title
        'show_bldob_meta_box', // $callback
        'obituaries', // $page
        'normal', // $context
        'default'); // $priority
}
add_action('add_meta_boxes', 'add_bldob_meta_box');

// Field Array
$prefix = 'bldob_';
$bldob_meta_fields = array(
	array(
    	'label' => 'Date of Birth',
    	'desc'  => '',
    	'id'    => $prefix.'bdate',
    	'type'  => 'date'
	),
	array(
    	'label' => 'Date of Death',
    	'desc'  => '',
    	'id'    => $prefix.'ddate',
    	'type'  => 'date'
	)
);

function show_bldob_meta_box() {
global $bldob_meta_fields, $post;

// Use nonce for verification
echo '<input type="hidden" name="bldob_meta_box_nonce" value="'.wp_create_nonce(basename(__FILE__)).'" />';

    // Begin the field table and loop
    echo '<table class="form-table">';
    foreach ($bldob_meta_fields as $field) {
        // get value of this field if it exists for this post
        $meta = get_post_meta($post->ID, $field['id'], true);
        // begin a table row with
        echo '<tr>
                <th><label for="'.$field['id'].'">'.$field['label'].'</label></th>
                <td>';
                switch($field['type']) {
                    // case items will go here

					break;

                } //end switch
        echo '</td></tr>';
    } // end foreach
    echo '</table>'; // end table
}

// Save the Data
function save_bldob_meta($post_id) {
    global $bldob_meta_fields;

Here is a link to the site

I want to make sure I am doing things the best efficient way. The site currently works great for the client but I really want to be able to showcase it as an awesome custom WordPress solution (like in the WP community & with other developers).
Any suggestions are greatly appreciated!

You’ve already done the important thing, structure the fields and use loops to manage the structure. Large amounts of disparate data often require a lot of code to deal with it, it’s just the way it is.

If all the meta boxes always appear together, you could combine everything into one meta box that uses tabs to keep the various groups organized. It’s just as organized as separate boxes, but takes up less screen space. It should reduce you code volume at least by the extra code for multiple boxes.
