Javascript and Wordpress Modification

Hello, i want your help to make some changes to my site. Today i buy an old theme (keremiya v5) it works but with some issues. like i say is a kind of old that means the developer no updated. my problem is on IMDB Importer. is not working anymore. 1) IMDB to TMDB i want to change the imdb importer with tmdb importer. [login to view URL] my site gonna have Greek traffic and tmdb support greek language, i want the descriptions of movies on greek. 2) Modification TMDB and Embed codes ***HOW IT WORKS NOW*** At the moment if you want to insert a link (and mirror links) is complicated, you should write all of that ([login to view URL]) : <!--title:Hdvid, Greek, 720p--> [login to view URL] <!--nextpage--><!--title:Openload, Greek, 1080p--> [login to view URL] <!--nextpage--><!--title:Streamcloud, Greek, 4K--> [login to view URL] <!--nextpage--><!--title:Openload, Greek, HD--> [login to view URL] <!--nextpage--><!--title:[login to view URL], Greek, Low Quality--> [login to view URL] and links also not working if is not iframe with embed code (except youtube links), what i mean ? if i put [login to view URL] not working but if i put <iframe scr="[login to view URL]" allowfullscreen="true"></iframe> works fine! ***HOW I WANT TO WORK*** 2.a) line and link, when i insert a direct link that take automatically the embed code from that direct link with favicon from site ([login to view URL]) 2.b) lets remove the Language option, the site gonna have movies only with greek subs, lets set greek language as default. 2.c) like i say before, line and link. lets change that code: <!--nextpage--><!--title:[login to view URL], Greek, Low Quality--> [login to view URL] and make works like this: [login to view URL],Low Quality if i dont insert ",quality" take automaticly HD. p.s. (dont forget, at the moment if i insert direct link not working, if i want to work i should insert iframe with embed code, i want you to fix that and make it to takes embed codes from direct links) 2.d) Trailers going here like this: [login to view URL] 2.e) If categorys is $id,$id (for tv-series and animes) enable the function for season and episode list like this: [login to view URL] (season number on buttons) and after that choice u do the same for episode list. example: Season > Episode > Source, miror link of specific season and episode. 2.f ) Add link in all published post, registered members can send us links for specific movie or tv-serie-season-episode. like this : [login to view URL] that link not auto published, i should approve first. 3) Edit Add content ( [login to view URL] ) for users. Like before, replace imdb importer with tmdb and remove all that fields ( [login to view URL] ) do it like this: Title : for title. TMDB ID: $id of tmdb and that id takes automaticly all important infos (trailer, genres, photo, stars, directror, etc.) Change Summary: with Greek Excerpt. remove all other fields and insert a field for links (like 2.c)
