When migrating from another system (i.e. Drupal), WordPress can require data that is currently serialized to be unserialized and stored in its own WordPress-specific tables/columns. This plugin can look for such data, and deserialize and store it, based on the plugin settings.
This plugin handles one (configurable) imported field at a time, so all imported, serialized data needs to be stored in that single field. Each key in that field can be mapped to any column, and stored in either <code>wp_postmeta</code> or <code>wp_posts</code>, as shown below:
<pre><code>`
</code></pre>
if ( $maps[$key][‘wp_table’] === ‘wp_postmeta’ && $value != ” && $value != NULL ) { 
 add_post_meta( $post_id, $maps[$key][‘wp_column’], $value, $maps[$key][‘unique’] ); 
} else if ( $maps[$key][‘wp_table’] === ‘wp_posts’ && $value != ” && $value != NULL ) { 
 $post = array( 
 ‘ID’ => $post_id, 
 $maps[$key][‘wp_column’] => $value 
 ); 
 wp_update_post( $post ); 
} 
 `
The <code>wp_schedule_event</code> method is used to deserialize the data and place it into its appropriate fields, and it can run at any configurable interval (you pick a number, and then a unit of time).

The JSM Show Term Metadata plugin displays term (ie. categories, tags, and custom taxonomies) meta keys and unserialized values in a metabox at the bottom of the term editing page.
There are no plugin settings – simply install and activate the plugin.
<h4>Shows Yoast SEO Term Meta</h4>
Yoast SEO stores its term (ie. categories, tags, and custom taxonomies) metadata in the WordPress options table, not the term meta table.
The JSM Show Term Metadata plugin can read and display Yoast SEO’s term metadata, but it cannot be deleted (as it does not reside in the WordPress term meta table).
<h4>Available Filters for Developers</h4>
Filter the term meta shown in the metabox:
<pre><code>'jsmstm_metabox_table_metadata' ( array $metadata, $term_obj )
</code></pre>
Array of regular expressions to exclude meta keys:
<pre><code>'jsmstm_metabox_table_exclude_keys' ( array $exclude_keys, $term_obj )
</code></pre>
Capability required to show term meta:
<pre><code>'jsmstm_show_metabox_capability' ( 'manage_options', $term_obj )
</code></pre>
Show term meta for a taxonomy (defaults to true):
<pre><code>'jsmstm_show_metabox_taxonomy' ( true, $taxonomy )
</code></pre>
Capability required to delete term meta:
<pre><code>'jsmstm_delete_meta_capability' ( 'manage_options', $term_obj )
</code></pre>
Icon for the delete term meta button:
<pre><code>'jsmstm_delete_meta_icon_class' ( 'dashicons dashicons-table-row-delete' )
</code></pre>
