RussellReal Posted February 28, 2009 Share Posted February 28, 2009 well.. in the script I altered for you.. I expect a GET variable called 'page' so you'd just do whatever.php?page=2 3 4 etc Quote Link to comment https://forums.phpfreaks.com/topic/147261-solved-displaying-images-from-a-folder-with-paginationpls-help/#findComment-773155 Share on other sites More sharing options...
timecatcher Posted February 28, 2009 Share Posted February 28, 2009 I think although im still a newby at the myself you can set up some kind of while statement so it checks what the most amount of pages is and automatically echos out the links to those pages, but Im busy so can't show you right now but I might later if you still need help.

RussellReal Posted March 1, 2009 Share Posted March 1, 2009 you get the number of pages by doing this 1 math operation: $numOfPages = ceil( TOTAL_IMAGES / MAX_IMAGES_PER_PAGE ); Quote Link to comment https://forums.phpfreaks.com/topic/147261-solved-displaying-images-from-a-folder-with-paginationpls-help/#findComment-773760 Share on other sites More sharing options...

RussellReal Posted March 2, 2009 Share Posted March 2, 2009 yeah that'd be pretty difficult to toy with what you should do, is avoid this whole loop thing, throw all the upload files into a database, with the filename and path to the file in the db, and an auto increment id that way you can order by descending an then get the filenames from there.

paparanch Posted March 2, 2009 Author Share Posted March 2, 2009 hehe...actually i already solved this one with database, but i want to try it without database so that i can just copy bunch of images to my folder at one time....which i can't do with database...T_T Quote Link to comment https://forums.phpfreaks.com/topic/147261-solved-displaying-images-from-a-folder-with-paginationpls-help/#findComment-774433 Share on other sites More sharing options...
