How to add classes to images based on their categories?
-
I need to be able to: 1.) assign categories to images and 2.) add classes to all images that correspond to their assigned categories.
I was able to add categories to images with the following:
function ug_add_categories_to_attachments() { register_taxonomy_for_object_type( 'category', 'attachment' ); } add_action( 'init' , 'ug_add_categories_to_attachments' );
And I found a function to add a class to images as so:
function add_image_class($class){ $class .= ' additional-class'; return $class; } add_filter('get_image_tag_class','add_image_class');
But I’m not advanced enough with php to take it much further. I tried this
function ug_add_image_class($class){ foreach(get_the_category() as $cat) { $class .= ' category-'.$cat->slug; }; return $class; } add_filter('get_image_tag_class','ug_add_image_class');
but no love…
Help? Ideas? Please? and Happy Friday!
