Display hidden custom field _values

Adding this snippet to the functions.php of your wordpress theme will allow you to display hidden custom field values. When a custom field value is prefixed within an underscore _value it will not be displayed, using this snippet will display them temporarily.

add_action( 'admin_head', 'showhiddencustomfields' );
function showhiddencustomfields() {
	echo "<style type='text/css'>#postcustom .hidden { display: table-row; }</style>\n";

  1. Is the same of add_filter( ‘is_protected_meta’, ‘__return_false’, 999 ); ?

    I don’t think it’s working for me… It should allow me to select hidden (underscore prefix) fields from the post editor screen in the custom fields section, right? I can select other custom fields but don’t see any _… ones. Not on posts or pages. Is it supposed to work for both? Thanks.

    1.  Hi Cliff, it should, Ill take a look and test this snippet with the most recent version of wordpress.
