JSM Show Post Metadata Plugin

Show post metadata (aka custom fields) in a metabox when editing posts / pages - a great tool for debugging issues with post metadata.

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

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' )
