script has bad coding in admin page when go to admin page to show all movies its start counting all movies , this slow the site and it cause the page to crash , i want a beter way to count it fast and show only 10 first movies and not load all im not sure but its like that the script load all movies first then shot the first 10 and total , but this cause the page to crash and slowness .. i want a better way to show first 10 posts and count total movies! i would like to add pagination on search result on the front end and total actors next to the total movies tab in the admin panel, no need to count tv-series, i wont add them at all! on the front end, it should be 25 items visible on the search page in the pagination. Pagination code is already there on front end page it need only some modification on search result and its codeigniter framework so it will simple! next movies tabs add actor tab that show actor names and total movies have that actor and option to delete actor , if i deleted actor all his movies should be deleted too!
