JSM Show Post Metadata

by JS Morisset

Version: 4.8.0

Download
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:

'jsmspm_delete_meta_capability' ( 'manage_options', $post_obj )

Icon for the delete post meta button:

'jsmspm_delete_meta_icon_class' ( 'dashicons dashicons-table-row-delete' )

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

Useful and Very Clean Post Meta Viewer Plugin

By Hesham Zebida (hishaman) on November 27, 2021

I've started recently to use this plugin to discover post meta values, I must say it's cleaner than other plugins I've used before. Thanks for the latest update release 2.0.0, the ability to have post meta updated without having to load the page is pretty awesome. I use the plugin almost everyday. I recommend it to anyone who wants to see what's in post meta. Keep it up!

Awesome! Now I can see all the fields attached to my posts!

Another great plugin by JSM
