simple image gallery help

[murratw]

The code below works well and shows all the images in a folder in reverse chronological order. But I want to limit it to a certain number of images .  This would enable me to have several pages of images.

 

So the first page would display the latest 50 images, the second page would show 50-100, and the third, 100-150.

 

Any helps on how to modify? I can create the pages manually. I just want to know how to limit the current page to a certain range.

<?php

//Your folder
$files = glob("images/*.*");

function sortnewestfilesfirst($a, $b) {
    return filemtime($b) - filemtime($a);
}
usort($files, "sortnewestfilesfirst");

$colCnt=0;
echo '<table border="0" style="width:1000px;">';

for ($i=0; $i<count($files); $i++)
  {
  $colCnt++;
  if ($colCnt==1)
  echo '<tr>';
  echo '<td width="20%" style="font-size:8.5px; font-family:arial">';

  $num = $files[$i];
   
echo ' 
  <div class="ImgBorder">
   <div class="clipout">
    <div class="clipin"> <a href="' . $num . '" rel="lightbox[all]"><img class="thumb ImgBorder" src="'.$num.'">  
</a> </div>
   </div></div>'."  ";


  echo '</td>';

  if ($colCnt==6)
    {
    echo '</tr>';
    $colCnt=0;
    }
  }

echo '</table>';
?>

You could use array and $_GET from PHP to accomplish your goal

 

<?php
//how many image per page?
$img_per_page = 20;

//default page
$page = 1;
//sanitize GET var
if ((isset($_GET["page"])) && (is_int($_GET["page"]))) $page = $_GET["page"];

//Your folder
$files = glob("images/*.*");

//max page possible
$max_page = ceil(count($files) / $img_per_page);

if ($page > $max_page) {
echo "there is no page"; //or other warning
} else {

function sortnewestfilesfirst($a, $b) {
//the rest of your code.....

echo '</table>';

//add pagination
for ($x = 1; $x <= $max_page; $x++) {
echo "<a href='yourpage.php?page=$x'>[ $x ] </a>";
}

}
