Meta Box Changelog

This version introduces new parameter for field: clone_empty_start that makes cloneable groups not showing inputs at first. When users want to enter data, they’ll need to click the “+ Add new” button. This feature updates the UI and makes it cleaner.

See more details on our blog post.

Other changes:

• Replace sprintf with string concatenation in RWMB_Field::show to fix issues when $field['before'] or $field['after'] contains special characters (%). Props Daniel Haim.
• Fix mismatch filter params for rwmb_meta when no fields are found.

• Make validation work for blocks

• Security fix for ajax getting posts

• Fix modal not updating URL (when add new)
• Security fix for ajax get posts/users

• Fix show hide checkbox tree

• Fix security issue when users set object id in the helper functions where they don't have permission to view (such as private posts)

Highlights:

Fix security issue of the output shortcode not escaping. Users can disable escaping (to revert the previous behavior) by adding this snippet:

add_filter( 'rwmb_meta_shortcode_secure', '__return_false' );
// or
add_filter( 'rwmb_meta_shortcode_secure_{$field_id}', '__return_false' );

Other changes:

• Fix compatibility with PHP 8.3

Highlights:

Add new icon field type, which supports Font Awesome Free, Font Awesome Pro and custom icon set. Can be used with icon font with CSS file or with SVGs. See the plugin docs for how to use it.

The icon field type will be added to the new version of Meta Box Builder soon, which will allow you to configure its settings with UI.

• Google Maps & OSM: ask for current user location for the map if there is no saved location or no default location is set (#1537)
• Fix media templates missing in blocks (#1536)

• Fix missing validation files

Highlights:

This version improves validation module, makes it work for file’s MIME types and in groups. More specifically, validation now works in the following cases:

• Cloneable fields
• file and image fields, both non-cloneable & cloneable.
• Subfields in groups, including file and image. For required subfields, asterisks are also added properly.

It works well with Meta Box Builder and with code.

An improvement for registering validation rules with code is that you only need to set field ID in all cases. Previously, you had to set like _file_{field_id}[] for files, or field_id[] for taxonomy fields.

• Output media templates only on edit pages

This option improves the existing option for taxonomy, and now works for post and user fields as well. It also works with cloneable fields and all field types (select_advanced, select, checkbox_list, radio and even select_tree and checkbox_tree).
