# 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:

```PHP

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.
