JSON Data Feed

Yes, you can! In your theme's functions.php file, you can use a filter to add whatever data you need. add_filter("get_json_meta", "my_metadata_function"); function my_metadata_function($metadata){ $myData = ""; //Add your data here. array_push($metadata, $myData); } Every post type also has it's own meta data filter. If you need to add metadata only to a single post type, add_filter("get_json_meta_{post_type}", "my_metadata_function"); function my_metadata_function($metadata){ $myData = ""; //Add your data here. array_push($metadata, $myData); } Any data you push onto the array will be available in {post}.meta section of the JSON feed.

Sure can! You can change that in the plug in settings. Settings can be accessed from Settings->JSON Data Feed.

Why yes, you can! Once again, through the magic of filters, anything is possible! add_filter("get_json_bloginfo", "my_bloginfo_function"); function my_bloginfo_function($bloginfo){ $myData = ""; //Add your data here. array_push($bloginfo, $myData); }
