how to get php to scan all subdirectories

[natturefrk]

I have been trying to figure this out for about a week now and cannot figure it out for the life of me. I have a script that displays images from a folder and I can limit the images displayed by what ever number I choose that is what $per_row is for. It has an more images link at the bottom of the div that feeds a function the id of the group to display the rest of the images. What I am trying to figure out is how to get php to scan all the directories and have a seperate div for each directory where the more images link will still feed the right id to the function.

 

Here is what I got so far:

 

 
<?php

echo '<link rel="stylesheet" type="text/css" href="../css/normalize.css" />';

echo '<link rel="stylesheet" type="text/css" href="../css/sizing.css" />';

echo '<link rel="stylesheet" type="text/css" href="../css/images.css" />';

include '../includes/connect.php';

include '../includes/vars/images.var.php';

include '../includes/functions/images.func.php';

$group_id = grab_group_id2($db, $album_name);

$dir = 'upload/hello/';

$per_row = 16;

if(file_exists($dir) == FALSE){
    
    echo 'Sorry, but the folder' . $dir . ' does not exist!';
    
}else{
    
    $dir_contents = scandir($dir);
    
    echo '<div class="images_container">';
    
    foreach ($dir_contents as $file) {
        
        $explode_image_filename = explode('.', $file);
        
        $file_type = strtolower(end($explode_image_filename));
        
        if($file !== '.' && $file !== '..' && in_array($file_type, $ext) == TRUE){
            
            if($counter % $per_row === 0 && $counter !== 0){
                        
                break;
                
            }
            
              echo '<a href="' . $dir . '/' . $file . '" alt="' . $file . '"><img src="' . $dir . '/thumbs/thumb_' . $file . '" alt="' . $file . '" class="images" /></a>';
                
                $counter++;             
                
        }
        
    }
            
            echo '<br /><a href="more_images.php?id='.$group_id.'" class="more-images-link">More Images...</a>';
}
        

?>

You can use the RecursiveDirectoryIterator class.

 

Working example

ok I got all the paths but how do I display the images in there own divs while limiting how much is displayed in those divs and still be able to us the more images link. I am really sorry for the noob question, but I have 0% knowledge about PHP OOP. Is there a way to do this with procedural coding?

 

This is what I got so far

 

$startpath = 'upload/';

$ritit = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($startpath, RecursiveDirectoryIterator::SKIP_DOTS), RecursiveIteratorIterator::CHILD_FIRST);
$r = array();
foreach ($ritit as $splFileInfo) {
   $path = $splFileInfo->isDir()
         ? array($splFileInfo->getFilename() => array())
         : array($splFileInfo->getFilename());

   for ($depth = $ritit->getDepth() - 1; $depth >= 0; $depth--) {
       $path = array($ritit->getSubIterator($depth)->current()->getFilename() => $path);
   }
   $r = array_merge_recursive($r, $path);
 
}

echo '<pre>';

print_r($r);

echo '</pre>';

I added wrong code above and can't edit it. Just realized it though.

 

$path = 'upload/';

/* @var $file SplFileInfo */
foreach (new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($path)) as $file) {
    if ($file->isFile()
        && in_array(strtolower($file->getExtension()), array('jpg', 'png', 'gif'))) {
        $all_paths = $file->getPathname()."<br>";
    
        //echo '<img src="'.$all_paths.'" />';
        
    }

}

 

When I echo $all_paths this is the output. So I am getting the paths. I tried to put $all_paths in the src attribute as you can see above but it just returns broken images.
