Adding Pagination to Gallery Script

Copy linkTweet thisAlerts:
Oct 03.2007

Hi,

I have a php gallery that automatically creates thumbnails via GD. [B]I have attached the php file within a zip file. [/B]

What I would like to have help with is I’m not sure how to add pagination to it. I’d like only 6 thumbnails to show up per page and have a type of navigation to go through the pages for a particular album.

Any help would be greatly appreciated! Thanks =]

@valenokOct 03.2007 — you have to select the appropriate images from db of elsewhere

for db you use - LIMIT from,to (WHERE 1 LIMIT 150,156)

will show you 6 images on page 26 (156/6)

for while use for()

@glitchgirlauthorOct 03.2007 — The thing is -- this script doesn't use a database -- I know how to do it if there was, but I'm building a website for a friend and their host allows php code but no database..

@MrCoderOct 03.2007 — Get the total amount of images divided by amount per page, in your case 6 this gives us the total number of "pages". (Use ceil())

Use a $_GET variable to store the current page number, we will call this $_GET["page"], default is 0.

Then simple build a sorted array of all the images in a folder and array_shift() 6 * $_GET["page"] images before displaying the final 6 images you want to display.

@valenokOct 03.2007 — I bet if she knows how to use limit she would deal with GET parameters.

Where do you store your images ?

In a folder getting them into array by readdir ?

You should sort you array by file's creation time back to front to ensure you have the latest newest images on the first page. use [I]multisort[/I] and [I]filectime[/I]

Then you just output them even not in cycle

< img src='createthubnail.php?img=".( intval($_GET['s']) + 1) ."'>

..

< img src='createthubnail.php?img=".( intval($_GET['s']) + 6) ."'>

echo "<a href='?".($s+7)."'>nextpage";

@sushiOct 13.2008 — Hey I have an idea for you.. you could encapsulate each set of images in divs with a class. And control them with javascript:

[CODE]link 1: onclick hide all except firstSet
link 2: onclick hide all except secSet
etc..


<div class="firstSet">lalalal 5 thumbs here alal</div>
<div class="secSet">lalalal alal</div>
<div class=thirdSet">lalalal alal</div>[/CODE]

Success!
