Integration with Molongui Authorship plugin

Hi, yes that would be possible.

You can filter and override author markup output using this filter: schema_wp_author, here is an example of code:

add_filter( 'schema_wp_author', 'schema_author_output_modify_8198771356' );
/**
 * Modify The Author Schema Markup in Schema Plugin
 *
 * @param array $author
 * @return array 
 */
function schema_author_output_modify_8198771356( $author ) {
  	
	// Modify author name
	$author['name'] = 'Another Name';
	
	// Modify description
	$author['description'] = 'Some other description';
	
	// Remove Author URL from the markup
	unset($author['url']);
	
	// Return the array
	return $author; 
}

P.S. Find more details and other example of how to modify author markup.

So practically, you can check if there is a guest author for a post, then get data from author post meta and return it.

I hope this helps.

Awesome, thanks Hesham!

You are welcome.
