Meta Box

Hello,

I try to reproduce the issue on the demo site but don't see that. I can set a date, save post and delete it as well. You can try to deactivate all plugins except Meta Box, MB extension plugin, switch to a standard theme of WordPress and check the issue again.

Hello,

You need to add the attribute edit_page to the frontend dashboard shortcode and assign the ID of the page where you add the frontend submission form, screenshot https://imgur.com/5Iy8aE8

The frontend dashboard shortcode would be:
[mb_frontend_dashboard edit_page="1807" post_type="news-message"]

Hello,

In case of using Bricks Builder, please reach out to them if you have any issues with installation, configuration, compatibility, or usage.
Refer to our support policy https://metabox.io/support/topic/support-policy/

Hello,

You can create a field group, then:
- add a number field with the ID _regular_price to add the product price.
- add the field group ID to the frontend submission form.
- add thumbnail value to the attribute post_fields to add a featured image.

the frontend shortcode looks like this

[mb_frontend_form id='product-meta' post_fields='title,content, thumbnail' post_type="product"]

Following the documentation https://docs.metabox.io/extensions/mb-frontend-submission/#field-order

When you output the coupon post with code, you can use the helper function rwmb_meta() to output the field value of the coupon post. Please follow the documentation
https://docs.metabox.io/functions/rwmb-meta/

Hello,

It is possible to use those functions in the View editor. You can see in your code, you are using a WordPress function as well get_terms()

{% set portfolios = mb.get_terms( args ) %}

View editor supports Twig, which is a PHP template engine. It doesn't mean "I bought meta box for not doing php, as I'm not a PHP coder". You should understand how the PHP function works to combine it with Twig code to use the view editor.

Following the documentation https://docs.metabox.io/extensions/mb-views/#twig

And last thing, if you are not familiar with PHP, you can contact us and request a customization code with an extra fee.

Hello Will,

Can you please clarify the question? Do you mean to add a custom field to the WooCommerce coupon post in the admin area? Or output the field value of a coupon post in the frontend?
