Function — Add custom fields for product data grid - martindubenet/Wordpress GitHub Wiki
A Custom Field is composed of a key and a value metadatas stored in the database and associated with a post type. You only need to create a new key once, after which you can assign a value to that key for every post (of the same type), if you so desire. You can also assign more than one value to a key.

if ( is_protected_meta( $keyt, 'post' ) ) {
continue;
}
$values = array_map( 'trim', get_post_custom_values( $key ) );
$value = implode( ', ', $values );
$html = sprintf(
'<dl class="meta-set"><dt class="post-meta-key">%s</dt><dd>%s</dd></dl>\n',
/* translators: %s: Post custom field name. */
sprintf( _x( '%s:', 'Post custom field name' ), $key ),
$value
);

$dl_html .= apply_filters( 'the_meta_key', $html, $key, $value );
}
if ( $dl_html ) {
echo '<section class="post-meta-list">\n{$li_html}</section>\n';
