I am wondering to add feed source url to node content type. I can call it through feed item (url) in views but through "views" i can not call feed item (url) in single nodes. Is there any way to output it to "node custom field display" or any way to call it in "panels"(i can use panel node display.. no problem). Or tell me how can i call this function in php so i can print php in node? I searched through drupal.org but i can not find a way to do so. Any help would be appreciated.
