Lately I have used jCarousel and Modx for a site with a photo gallery and it works quite well. Since it works with a simple unordered list on the gallery page I got to thinking that it would be nice to have a snippet that could return the contents of an assets directory in that list item format.

It seems this would create a gallery within Modx that the CMS user could manage by simply uploading to/deleting from a specified directory. Has anyone done anything like this?

I've done something similar (if I'm understanding you).  It's a fairly simple process.

I've adapted some code I had laying around. This is very quick and dirty code and untested, but should get you started.

Code:

<?php

// Shows all files in the directory,

$newline = "<br/>";

$dir = $modx->config['base_path'].'assets/yourfiles'; // set path to files

$dir_array = array(); // main array - contains all file names in directory


// open directory and parse file list

if (is_dir($dir)) {

   if ($dh = opendir($dir)) {

      // iterate over file list to create full directory array

      while (($filename = readdir($dh)) !== false) {

          if (($filename != ".") && ($filename != "..") && ($filename != "WS_FTP.LOG")) { // skip self, parent, and ftp log

   $dir_array[] = $filename; // add the filename to the array
          }
      }
      closedir($dh);  // close directory
   }

   natsort($dir_array); // sort in ascending order -- delete if you don't need them sorted.
   // $dir_array = array_reverse($dir_array, false); // reverse array (descending) if needed.

   $n = count($dir_array); // total number of files -- might want this for something

    $output = "";

    $output .= "<ul>"

    foreach ($dir_array as $value) {  // iterate through array of filenames.

         $output .= '<li>'.$value.'</li>';

    }

    $output .='</ul>';
    
}

return $output;

?>

BTW, you might look at the MaxiGallery snippet if you haven't already. It does all this for you and makes for much easier and more full-featured gallery management by the users (e.g. picture order, uploading and deleting, titles, descriptions, dropshadows, masks, slideshow, etc).

Hope this helps,

Bob

Hey BobRay -

I am working w/ Greg on this and we think we almost have it.  The only thing we want to do now is to exclude the .thumb_ file prefix so the thumbnails don't show, do you have any suggestions for that?

We tried this,

if (($filename != ".") && ($filename != "..") && ($filename !=
"WS_FTP.LOG") && (!preg_match('/^\.*thumb_$/', $filename ) ) { // skip
self, parent, and ftp log and thumb prefix

and it didn't seem to exclude them,
thanks for your help in advance.

using strstr or stristr would be easier... http://ch2.php.net/stristr

I think that @pleth has it working now. He found me on twitter and I gave him the correct pattern to add to BobRay's post.

I changed the following:

Code:

if (($filename != ".") && ($filename != "..") && ($filename != "WS_FTP.LOG")) { // skip self, parent, and ftp log

to

Code:

if (($filename != ".") && ($filename != "..") && ($filename != "WS_FTP.LOG") && (!preg_match('/^.thumb_/', $filename))) { // skip self, parent, and ftp log

And it works.

The pattern just checks to see if the filename starts with .thumb_ and if it does skip it.

Thanks guys, we appreciate the help.

Just thought I would post this to let you know where we ended up on this. I realize there are other solutions available and am planning on diving into MaxiGallery next but this solution proved sufficient as well as a good exercise. Maybe this will be useful to someone as I think it could be applied to other types of documents. Once again, thanks.

Code:
