I am creating a plugin called BANDS for my personal site which basically sits under PAGES and has added metaboxes to add band details such as videos, soundcloud & crucially Festival Appearances.
I have now created the plugin and it works really well for what I need. I have a new menu item called 'bands' for all my pages and the metaboxes in admin I require for the extra information.
I have one or 2 small issues left - 1 which is really vexing me! As you will see in the code below - I have one section called "Festival Appearances" which has a field for the festival name & then then the date of the show. I want to make this field a REPEATABLE field so the user can click a "add another +" link and get a new meta box to enter a 2nd festival appearance.
I have seen plenty of code to do it but am having a real hard time mixing it with what I have.
Along the way I wouldn't mind making the date field a 'date picker' rather than the standard text area if anyone know how?
Any help would be greatly appreciated! Code below:
// Registers the new post type and taxonomy
function wpt_bands_posttype() {
register_post_type( 'bands',
array(
'labels' => array(
'name' => __( 'Bands' ),
