single_page & thumbnail

Permalink 1 user found helpful
I have a package with several single_page pages.

Within one of the pages I wish to display the thumbnail of an asset from the library.

I have the fID of the asset... how do I (or indeed can I) use that to retrieve the thumbnail..?

$imgHelper = Loader::helper('image'); 
$imgHelper->getThumbnail($fileObj, 75, 75)->src

Thats great remo... and it does work... however... this only works for images and I need to display a thumbnail regardless of file type just like in the asset manager where zip files show a zip icon thumbnail.

I could do it by parsing the file extension and having icons to hand as part of my package but it seems C5 is able to do this itself.

I guess what I'm really after is the thumbnail associated with the asset identified by fID

Do you know of a way to do this from a single page given the fID...?

ah I see. That should be possible too. You have to work on the FileVersion object though.

There's a method called getThumbnail. I've seen the first paramter set to 1 and 2. You can also check if there's a generate thumbnail by using hasThumbnail

Try to start by calling "getVersion" on your file object.. There you should find everything you need

maybe something from here?

http://svn.concrete5.org/svn/concrete5/trunk/web/concrete/helpers/i...

public function getThumbnail($obj, $maxWidth, $maxHeight) {
      if ($obj instanceof File) {
         $path = $obj->getPath();
      } else {
         $path = $obj;
      }      
      $fh = Loader::helper('file');
      if (file_exists($path)) {
         $filename = md5($path . ':' . $maxWidth . ':' . $maxHeight . ':' . filemtime($path)) . '.' . $fh->getExtension($path);
      } else {
         $filename = md5($path . ':' . $maxWidth . ':' . $maxHeight . ':') . $fh->getExtension($path);
      }
      if (!file_exists(DIR_FILES_CACHE . '/' . $filename)) {
         // create image there
         $this->create($path, DIR_FILES_CACHE . '/' . $filename, $maxWidth, $maxHeight);

Cheers Remo...

This was my solution...

$f = File::getByID(fID);
$fv = $f->getApprovedVersion();
$src = $fv->getThumbnail(1);
