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).

With <a href="https://github.com/pixelgrade/pixfields" rel="nofollow ugc">PixFields</a> you can have a custom fields visual manager.
Note: this plugin does not add any style to the output of custom fields. Its just adding metadata and offers a way to overwrite the html from the theme. 
The theme should style the output of the metadata.

PixFields offers you a nice interface to add custom metadata into your favorite post type.
