Preview custom fields WordPress Plugin

About this plugin

This plugin adds support for a missing piece of WordPress functionality regarding the previewing of post types with custom meta fields.

By default, the WordPress CMS only stores revisions and preview data for the primary title (post_name) and content (post_content) fields. Meta fields are not included which results in inconsistencies when attempting to view a preview version of a post type item.

This plugin hooks into the points at which a valid preview revision is made and enforces the saving of all associated custom fields for the item being previewed.

Installing

To install, simply download a .zip version of this repository and upload to your WordPress instance via the Admin screens, Plugins -> Add New -> Upload Plugin. Finally, active the plugin.

Usage

Every time a post item is previewed, this plugin will loop through an array of custom field meta keys and ensure they are saved correctly against the revision or autosave for the current item.

In order to add fields to this process you will need to use the following class function:

PreviewCustomFields::add_meta_keys([
  '_cmb2_page_author_name',
  '_cmb2_page_author_age'
]);

The code above adds the two example custom fields _cmb2_page_author_name and _cmb2_page_author_age fields. You can call this method as many times as required or all at once.
