PHP动态画廊分页(略有不同) [英] PHP Dynamic Gallery Pagination (with a twist)
问题描述
好吧，我正在使用PHP显示动态画廊...我要的是代替在一页上显示很多缩略图，而宁愿进行分页..您知道数字页以及下一页以及全部..
well i am displaying a dynamic gallery using PHP... what i want is to instead of showing a lot of thumbnails on one page i rather do paging.. you know the number pages and next and all..
这是一件老事了，但我不知道该怎么做.
well its an old thing but i don't know how to do this..
- 如何做?
但抱住马匹扭腰
我在DIVS中显示缩略图，我在行中设置了缩略图，所以可以说如果有人打开1024x768的页面，则我会连续获得3个缩略图，并且有6行，因此它们总共制作了18个缩略图.
i am showing thumbnails in DIVS which i set in line so lets say if someone open the page in 1024x768 i get 3 thumbnails in a row and and there are 6 rows so they make 18 thumnails on the whole..
但是，如果有人打开其分辨率为1600 x 1200的页面，则我连续获得5个缩略图，因此18个缩略图将构成3行..可以说我想保留第6行并将缩略图弹出至30. .. 如何使用代码来做到这一点
but if someone open the page with their resolution lets say 1600 x 1200 i get 5 thumnails in a row so 18 thumbnails would make 3 rows.. lets say i want to keep the rows 6 and pop up the thumbnails to 30... HOW TO RIDE A CODE TO DO THAT
p.s.祝我疯狂的唐卡好运....
p.s. best of luck with my crazy thangs....
推荐答案
基本技术是这样的:您知道或计算每页显示多少图像.因此，当您进行查询时，这就是您的LIMIT.另外，您将需要一个偏移量-您需要跳过多少个结果.如果您每页显示8个结果，并且要显示第3页，则偏移量将为(3-1)* 8或16.
The basic technique is this: You know, or else calculate, how many images you're displaying per page. So when you do your query, that's your LIMIT. Also, you're going to need an offset - how many results you need to skip over. If you were showing 8 results per page and you wanted to show the 3rd page, your offset would be (3 - 1) * 8, or 16.
现在，您的有趣挑战听起来像是显示屏:您将根据显示屏显示不同数量的缩略图.因此，您可能需要使用javascript来计算所需的显示大小，然后基于显示的页面发出ajax请求以查询所需的结果量和偏移量.
Now, your interesting challenge sounds like your display: You're showing different amounts of thumbnails based on the display. So you will need to calculate how big of a display you want, probably with javascript, and then make an ajax request to query for the amount of results you want and the offset, based on the page you're showing.
