To display checkboxes on front end in wordpress metabox - php

Question

I am building a plugin that provides author names as checkboxes on the admin side. The names that have been checked should be displayed on the front-end side in Wordpress.
I have written the code for the admin side, i.e. my code provides checkboxes and its values are saved.
How should the checked values be displayed on the front end?
<?php
add_action('add_meta_boxes', 'add_custom_boxx');
function add_custom_boxx($post) {
add_meta_box(
'Meta Box', // ID, should be a string.
'Featured People', // Meta Box Title.
'people_meta_boxx', // Your call back function, this is where your form field will go.
'post', // The post type you want this to show up on, can be post, page, or custom post type.
'side', // The placement of your meta box, can be normal or side.
'core' // The priority in which this will be displayed.
);
}
function people_meta_boxx($post) {
wp_nonce_field('my_awesome_nonce', 'awesome_nonce');
$checkboxMeta = get_post_meta($post->ID);
$html = "";
$blogusers = get_users('blog_id=1&orderby=nicename&role=author');
// Array of WP_User objects.
foreach ($blogusers as $user) {
?>
<input type="checkbox"
name="<?php echo $user->display_name;?>"
id="<?php echo $user->display_name;?>"
<?php if (isset($checkboxMeta[$user->display_name])) {
checked($checkboxMeta[$user->display_name][0], 'yes'); } ?> />
<?php echo $user->display_name;?><br />
<?php
} // end foreach
?>
<?php } // end function people_meta_boxx
add_action('save_post', 'save_people_checkboxesx');
function save_people_checkboxesx($post_id) {
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
return;
if ((isset($_POST['my_awesome_nonce'])) && (! wp_verify_nonce($_POST['my_awesome_nonce'], plugin_basename(__FILE__))))
return;
if ((isset($_POST['post_type'])) && ('page' == $_POST['post_type'])) {
if (! current_user_can('edit_page', $post_id)) {
return;
}
} else {
if (! current_user_can('edit_post', $post_id)) {
return;
}
}
$blogusers = get_users('blog_id=1&orderby=nicename&role=author');
// Array of WP_User objects.
foreach ($blogusers as $user) {
//saves bob's value
if (isset($_POST[$user->display_name])) {
update_post_meta($post_id, $user->display_name, 'yes');
} else {
update_post_meta($post_id, $user->display_name, 'no');
}
}
}
function display_contributors($content) {
//Code to be inserted here.
return $content;
}
add_filter('the_content','display_contributors');
?>
