Get All Photos From Folder and Paginate With PHP - php

Question

I'm trying to build a site that has a photo gallery and rather than build a database CMS I'm trying it with the use of PHP and folders. At the moment I have a script to get all of the images in a folder and display them on a page, however as there are going to be probably in excess of 100 photo's I'd like to use pagination to spllit this over several pages but I have no idea how to do this.
Here is the script I'm currently running:
<?php
$folder = 'cms/gallery/photo/';
$filetype = '*.*';
$filename = HOW DO I GET THE NAME WITHOUT FILE TYPE
$files = glob($folder.$filetype);
foreach ($files as $file)
{
echo '
<div class="galleryCellHolder">
<div class="galleryCell">
<a class="fancybox" rel="group" href="'.$file.'"><img class="galleryPhoto" src="'.$file.'" alt="'.$filename.'"></a>
</div>
</div>
';
}
?>
Q1 - How do I extract the file name without the file extension?
Q2 - How do I paginate this for say 24 images per page?

Answer 1

For paging you must calculate the total items to page , capture the parameter of the current page and iterate over the respective range.
<?php
$folder = 'cms/gallery/photo/';
$filetype = '*.*';
$files = glob($folder.$filetype);
$total = count($files);
$per_page = 6;
$last_page = (int)($total / $per_page);
if(isset($_GET["page"]) && ($_GET["page"] <=$last_page) && ($_GET["page"] > 0) ){
$page = $_GET["page"];
$offset = ($per_page + 1)*($page - 1);
}else{
echo "Page out of range showing results for page one";
$page=1;
$offset=0;
}
$max = $offset + $per_page;
if($max>$total){
$max = $total;
}
You can use the function pathinfo to get the file name without extension.
//print_r($files);
echo "Processsing page : $page offset: $offset max: $max total: $total last_page: $last_page";
show_pagination($page, $last_page);
for($i = $offset; $i< $max; $i++){
$file = $files[$i];
$path_parts = pathinfo($file);
$filename = $path_parts['filename'];
echo '
<div class="galleryCellHolder">
<div class="galleryCell">
<a class="fancybox" rel="group" href="'.$file.'"><img class="galleryPhoto" src="'.$file.'" alt="'.$filename.'"></a>
</div>
</div>
';
}
show_pagination($page, $last_page);
Using the following function you can create the navigation links
function show_pagination($current_page, $last_page){
echo '<div>';
if( $current_page > 1 ){
echo ' <<Previous ';
}
if( $current_page < $last_page ){
echo ' Next>> ';
}
echo '</div>';
}
?>
