image gallery needs limit and page count

woods42

This script reads a directory and shows thumbnails of all the photos in it. I need to make it loop to show xx amount of images per page and show a page navigation at the bottom such as " prev 2 3 4 5 next page" and so on. here is the full gallery script..... thanks. all i know is the loop needs to go someone around the line that says "//Loop through them all ." thanks for any help

the file is attached

Most common method of doing this is to pass a starting point (and if you want to make it be able to have different amounts, a total) by GET eg:

http://www.yourdomain.com/images.php?start=50&limit=10

then make your Query something like this :
SELECT
image_information
FROM
image_table
LIMIT $start,$limit

then to make the links_to the next page :

echo "<A HREF='http://www.yourdomain.com/images.php?start=", $start+$limit , "&limit=", $limit , "'>Next Page</A>";

This tutorial has good information on developing a good pagination system for a script.

the images are not in a database

whoops where is my brain!!!
for some reason I thought you would be storing the image information in a database, and overlooked the "reads a directory" portion. sorry!

Ok, i got the page count.... and then divide by 30 images per page which give me the total pages.. I have no idea how to make a link to the next page and have it come back with the same variables and start displaying the next images.

$counter = 0;
while($file = readdir($dir)){
if($file != '.' && $file != '..'){
If(!is_dir($full_server.$album.$file)) {
$counter++;
}
}
}
closedir($dir);

$dir=@opendir($full_server.$album);
$pagetotal = $counter / 30;
$pagetotal = ceil($pagetotal);
