Hooks Help

Where do I add the hook for this? It is three functions deep.
tainacan_the_metadata > tainacan_get_the_metadata > >get_metadata_as_html.
I would like to pull the session data and the link associated, like this:

and put it here:

The function in question:

I would like to pass

array(
							'metadata'	=> 'session'
};

to it. I guess I am having trouble finding hooks.

Hi @eeszarek, maybe this one?

tainacan/tainacan/blob/develop/src/classes/entities/class-tainacan-item.php#L787


      
          
          
			// Renders the metadatum name
          			$metadatum_title_before = $args['before_title'];
          			$metadatum_title_before = apply_filters( 'tainacan-get-item-metadatum-as-html-before-title', $metadatum_title_before, $item_metadatum );
          			$metadatum_title_after = $args['after_title'];
          			$metadatum_title_after = apply_filters( 'tainacan-get-item-metadatum-as-html-after-title', $metadatum_title_after, $item_metadatum );
          			$return .= $metadatum_title_before . $item_metadatum->get_metadatum()->get_name() . $metadatum_title_after;
          			
          			// Renders the metadatum value
          			$metadatum_value_before = $args['before_value'];
          			$metadatum_value_before = apply_filters( 'tainacan-get-item-metadatum-as-html-before-value', $metadatum_value_before, $item_metadatum );
          			$metadatum_value_after = $args['after_value'];
          			$metadatum_value_after = apply_filters( 'tainacan-get-item-metadatum-as-html-after-value', $metadatum_value_after, $item_metadatum );
          			$return .= $metadatum_value_before . ( $item_metadatum->has_value() ? $item_metadatum->get_value_as_html() : $args['empty_value_message'] ) . $metadatum_value_after;
          
          
			$after = $args['after'];
          
          
			// Let theme authors tweak the wrapper closer
          			if ( is_numeric($metadatum_index) ) {
          				$after = apply_filters( 'tainacan-get-item-metadatum-as-html-after--index-' . $metadatum_index, $after, $item_metadatum );
          			}

Could you explain in more details what you are trying to achieve? Maybe there is a way vie theme but there are several filters in the _as_html functions. In this case, the $item_metadatum object should contain information from the current item, the metadata and its value.
