Pagination for my situation? - php

Question

I have a pretty complicated script that doesn't fully work with MySQL, it does partially though. Let me try to explain...
The results of my page are purely image names from a specific folder, means I use this function to get my results:
function get_all_images($dir)
{
$dir = opendir($dir);
$dirArray = array();
while($entryName = readdir($dir))
{
if(($entryName != ".") && ($entryName != "..") && ($entryName != ".svn") && ($entryName != ".htaccess"))
{
$dirArray[] = $entryName;
}
}
closedir($dir);
(sizeof($dirArray)) ? arsort($dirArray) : '';
return (is_array($dirArray)) ? $dirArray : '';
}
This is how I basically get results in my page:
<?php
include('includes/header.php');
$images = get_all_images('i');
$url = str_replace('www.', '', generate_site_url());
$flag = false;
$count = 0;
if (empty($images))
{
echo '<h2>There are no uploaded images</h2><br>';
}
foreach ($images as $image)
{
$filename = $image_name = $image;
$image_link = $url . IMAGES_PATH . $filename;
$user_id = fetch_user_id($image_link);
$delete_link = (isset($_POST['delete_link'])) ? $_POST['delete_link'] : '';
$delete_image = (isset($_POST['delete_image'])) ? $_POST['delete_image'] : '';
if ($delete_admin_submit)
{
unlink('./t/' . $delete_image);
unlink('./t/big' . $delete_image);
adminDelete('./i/' . $delete_image, $delete_link);
header('Location: ' . $imgit_action);
exit();
}
echo '<div class="' . ($count++ % 2 ? "odd-color" : "even-color") . '">';
echo '<table>';
echo '<tr><td class="fullwidth"><a class="preview_img" href="' . $image_link . '"><img src="' . $image_link . '" title="Click to enlarge" width="300" class="thumb" /></a></td></tr>';
echo '<tr><td><span class="default">Direct link:</span> ';
echo '<input type="text" readonly="readonly" class="link-area" onmouseover="this.select();" value="' . $image_link . '" />';
echo '<form method="post" action="" onsubmit="return confirmSingleDeletion();" style="display: inline;"> ';
echo '<input type="submit" class="icon_delete" name="delete_link" value="' . $image_link . '" title="Delete this image" />';
echo '<input type="hidden" name="delete_image" value="' . $image_name . '" />';
echo '</form>';
echo '</td></tr>';
echo ($flag) ? '<hr /><br>' : '';
echo '</table>';
if (!empty($user_id))
{
echo '<br><strong class="normal">Uploader ID:</strong> ';
echo '<em class="normal">' . $user_id . '</em><br>';
}
echo '<br>';
$flag = true;
}
?>
<span class="button-sub">« Back to Index</span>
<?php echo '</div>'; ?>
<?php include('includes/footer_alt.php'); ?>
Now I have not ANY simple clue how to start breaking my results into pages. I'm working here with over 12000 results and it takes a lot for the page to load, I need help to break this big result into pages.
Anyone willing to help me? At least give me a clue how to start? I would be really grateful.
Thanks a lot for reading.

Answer 1

Consider your array as you collect up the file names but after you have sorted them:
$imgs = array(
0 => 'image1.jpg',
1 => 'image2.jpg',
2 => 'image3.jpg',
3 => 'image4.jpg',
4 => 'image5.jpg',
5 => 'image6.jpg',
6 => 'image7.jpg',
7 => 'image8.jpg',
);
// create some vars which you can use in your pagination
$perpage = 3 ;
$page=2;
$range_end = ($perpage*$page)-1;
$range_start = ($perpage*($page-1));
$display=range($range_start,$range_end);
// loop through results
foreach($display as $show){
echo $imgs[$show];
}
Does that get you a start?

Thanks for trying to answer me Cups and Umair Khan, but I found the working solution here:
