JSM Show Post Metadata

by JS Morisset

Description

The JSM Show Post Metadata plugin displays post (ie. posts, pages, and custom post types) meta keys (aka custom field names) and unserialized values in a metabox at the bottom of the post editing page.

Note that if you’re using WooCommerce HPOS (High-Performance Order Storage), available since WooCommerce v8.2, then your WooCommerce orders are NOT post objects and you should use the JSM Show Order Metadata plugin instead.

There are no plugin settings – simply install and activate the plugin.

Available Filters for Developers

Filter the post meta shown in the metabox:

'jsmspm_metabox_table_metadata' ( array $metadata, $post_obj )

Array of regular expressions to exclude meta keys:

'jsmspm_metabox_table_exclude_keys' ( array $exclude_keys, $post_obj )

Capability required to show post meta:

'jsmspm_show_metabox_capability' ( 'manage_options', $post_obj )

Show post meta for a post type (defaults to true):

'jsmspm_show_metabox_post_type' ( true, $post_type )

Capability required to delete post meta:

This plugin is incredibly helpful when converting and managing legacy websites, especially for uncovering all kinds of hidden metadata - even the obscure ones.

It's great for letting me see hidden metadata without having to open up the database. Plus, it's great for allowing non-technical users to see the information without the risk of sending them to the database.

Very useful plugin
