Meta Box

Thanks. I see WP has filters for default content and some others, but not for meta. 🙁 A bit hacky, but I got the desired result with some JS:

add_action( 'admin_footer', function() {
?>
    <script>jQuery(function($){
        var $input1 = $('.post-new-php.post-type-staff_testimonial input[name="attributes[0][heading]"]');
        if(!$input1.length) return;
        var $clone1 = $input1.closest('.rwmb-clone');
        $clone1.siblings('.add-clone').click().click();
        var $clones = $clone1.siblings('.rwmb-clone');
        $input1.val('Position');
        $clones.first().find('input[name^="attributes"]:first').val('Team Member');
        $clones.last().find('input[name^="attributes"]:first').val('Location');
    });</script>';
<?php
} );

I already was, and when that didn't do what I want, I changed it to a callback, and the callback does not update dynamically, so I can't use the builder per your other suggestion.

Thanks. That is disappointing.

This is getting really annoying. I'm about ready to uninstall Metabox and switch to ACF. Under active development, I need to push changes from dev to staging frequently, and it's frustrating having to go in to each field group and re-save it.

Long Nguyen, a staging or dev site is a duplication of a site, where all the files and database are copied over. After making changes, a staging site can be "pushed to production" on most platforms, where the database and files are copied back to the public site. Exporting and importing MB settings would be redundant to this process, and also quite a lot of hassle.

I'm wondering why MB requires me to go into the group and hit the Update button, just to work again after moving between dev/staging/production. This doesn't happen with ACF or most other plugins.
