FieldRadar

A lightweight WordPress plugin to discover which meta fields for a post type are actually populated and which posts use them.

Features

• Finds the relevant post meta fields for the selected post type
• Finds the list of posts that have the selected meta key along with total count.

Installation

1. Copy the fieldradar folder to your site's wp-content/plugins directory.
2. Activate the plugin on the Plugins screen.
3. Go to Tools -> FieldRadar

Usage

In WordPress Admin go to: Tools → FieldRadar

• Select a post type (the plugin lists public post types).
• Click "Load fields" to list candidate fields/meta keys for that post type.
• Click "Show posts" for any field to see which posts have that field populated.

Limitations & caveats

• Large sites: scanning postmeta and loading values for many posts can be slow and memory-heavy. Create issue or reach out for any questions using contact page.
• The plugin only checks postmeta; if your field values are stored elsewhere (e.g. embedded JSON in post content, remote storage, or custom tables) they will not be detected.
