How to Add Custom Taxonomy Conditional Tag in WordPress

Are you looking for a way to add custom taxonomy conditional tag? While there’s probably a plugin for this, we have created a quick code snippet that you can use to add custom taxonomy conditional tag in WordPress.

Conditional tags are a useful tool for those who want interactive and more awesome themes. They let you place if-statements and do stuff if certain conditions are true.

Since WordPress 3.0 you can add your own taxonomies, but unfortunately there are no conditional tags for it, so you’ll have to add your own.

How to use:

if ( has_person( 'tom-cruise' ) ) {
/* do something */
};

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

function has_person( $person, $_post = null ) {
	if ( empty( $person ) )
		return false;
	if ( $_post )
		$_post = get_post( $_post );
	else
		$_post =& $GLOBALS['post'];
	if ( !$_post )
		return false;
	$r = is_object_in_term( $_post->ID, 'person', $person );
	if ( is_wp_error( $r ) )
		return false;
	return $r;
}
