Hi All,

I have the following code:

<?php

$files = array_merge(glob("*.jpg"), glob("*.JPG"),

                    glob("*.JPEG"), glob("*.jpeg"));


array_multisort(

    array_map( 'filemtime', $files ),

    SORT_DESC,

    $files

);


//simple foreach loop

foreach($files as $photo) {

   //replace thumbnails to thumbnails directory

   $thumbnail = str_replace('.', '.', $photo);

   echo '<li><a href="'.$photo.'"><img src="'.$thumbnail.'" alt=" " width="120" height="120" /></a></li>';

}

?>

I would like to add pagination to it that it will show certain amount of photos per page.

Thanks in advance,
Amir

Pagination? If you want to do that you'd need to count the elements and do a while or for loop to iterate through them, stopping at the end of the page and offsetting based on the page you are on.

<?PHP
//?p=1
$perPage = 20;
$page = (int)$_GET['p']; // 1
$i = ($page-1)*$perPage; //offset = 0
$max = $i+$perPage; // Max = 20

while($i < $count && $i  < $max) {
//code goes here
}

Hi,
Found the way:

 <?php



$files = array_merge(glob("*.jpg"), glob("*.JPG"),

                    glob("*.JPEG"), glob("*.jpeg"));


array_multisort(

    array_map( 'filemtime', $files ),

    SORT_DESC,

    $files

);


array_multisort(array_map('filemtime',$files),SORT_NUMERIC,SORT_DESC,$files); // Sort by modified date


$page = empty($_GET['page']) ? 1 : $_GET['page'];

$num_per_page =16;

$total_pages = ceil(count($files)/$num_per_page);

$break=1;

echo "<div id='gallery'><ul>";

for($i = ($page - 1) * $num_per_page; $i < $page * $num_per_page; $i++) {


if($files[$i] != '')

echo "<li><a href=\"$files[$i]\"><img src=\"$files[$i]\" width=\"120\" height=\"120\" alt=\"$files[$i]\" /></a></li>";

}

echo "</ul></div>";

if($break==6){echo "<br/>";} // Breaks the table into two rows of 6

if($break==12){echo "<br/>";}


$break++;


echo "<br/>";

if ($page == 1)

{

}

else

{

$first = 1;

$prev = $page-1;

echo "<a class='s'  href=\"$self?manage=media&page=$prev\"><img src=\"..\images\lightbox-btn-prev.gif\" alt='previous' /></a> ";

}


if ($page < $total_pages)

{

$next = $page+1;

echo " <a class='s' href=\"$self?manage=media&page=$next\"><img src=\"..\images\lightbox-btn-next.gif\" alt='next' /></a>";

}

else

{

$next = ''; 

$last = ''; 

}


?>

In this way also the rest of the javascript working pefect.

Thanks,
Amir
