Showing thumbnails in blog - problem after hosting move, maybe caching?

Permalink August 22, 2014 at 11:23 AM

Here's the code that should show thumbnails in a custom blog template, on a site running Concrete 5.5.1 on php 5.3.1:

for ($i = 0; $i < count($cArray); $i++ ) {
      $cobj = $cArray[$i]; 
      $title = $cobj->getCollectionName();
      $link = $nh->getLinkToCollection($cobj); 
               $pt = $cobj->getCollectionAttributeValue('page_thumbnail');
                  if($pt){
                     echo("<a href=\"$link\">");
                     $imgHelper->outputThumbnail($pt, 190,190, $title);
                     echo("</a>");
            }
}

$link and $title are displayed correctly, but image src, width and height are not. They worked on the old server, but not on the new one.

I tried adding

print_r($pt)

and got, for example:

File Object ( [error] => [fID] => 6558 [fDateAdded] => 2014-07-24 20:00:32 [uID] => 5 [fslID] => 0 [ocID] => 0 [fOverrideSetPermissions] => 0 [fPassword] => [fvID] => 1 )

When I did:

if (is_object($pt[0])) { }

the template died completely and showed nothing.

Here is the page I am working on, complete with output of print_r

I'm sure I'm missing something here, and would really appreciate any help!

Do you have this at the top of your document

<?php  
   defined('C5_EXECUTE') or die(_("Access Denied."));
   $textHelper = Loader::helper("text"); 
   $imgHelper = Loader::Helper('image');

Thanks for looking! Yes, I have those lines in there.

The code I gave is also inside an if statement: if (count($cArray) > 0) {

That seems to be working correctly.

As I said, this exact code was showing images on a different server: unfortunately, that server was so overloaded that it was causing tons of other problems, so the site had to be moved. I assume that there must be some minor difference in the configuration on the new server that is stopping the code from working.
