function for displaying exhibit item thumbnail?

[Jonathan Reeve]

Hi everyone,

I'm making a new Omeka theme, and one of the things I'm trying to do is display thumbnails for exhibits. That's to say, I'd like the "Browse Exhibits" page to display associated images for each exhibit. I copied the Exhibit Builder plugin's exhibits/browse.php to my theme directory, and it seems to be working, but I can't seem to find a function that will allow me to display a thumbnail image of an item associated with an exhibit. Ideally, I'd like for the "Browse Exhibits" summary of the exhibit to contain a title, description, thumbnail image, and tags, but right now it only displays title, description, tags. It seems like it'd be easy to get the first thumbnail from the first item in the exhibit, but I can't seem to select it correctly. 

So far I've tried adding this code to browse.php, after the <h2> line: 

    <div class="exhibitImage"><?php echo exhibit_builder_exhibit_thumbnail(1); ?></div>

but I get: 

    Zend_Controller_Router_Exception: section_slug is not specified

I also tried: 

                <div class="exhibitImage">

<?php set_current_item(get_item_by_id(1)); ?>

<?php echo exhibit_builder_exhibit_display_item(); ?>

</div>  

but I get: 

    Catchable fatal error: Argument 1 passed to set_current_item() must be an instance of Item, null given,

Please forgive my lack of knowledge about this--I'm still working my way through the Omeka API. What I'd like to know is, is there a function for displaying an image from an exhibit? If so, how do I 1) select the first item in the currently selected (looping) exhibit? 2) Display the thumbnail from that item? Any help would be greatly appreciated.

Hi Jon,

Here is what I am doing to display the image from first item in first page in exhibit hope it help.
Maybe there is a better way to do that, but you can try this.

  $itemcount=0;
      $page="";
      $section = $exhibitobject->getFirstSection();
      if(!empty($section)){
          $page= $exhibitobject->getFirstSection()->getPageByOrder(1);
      $itemcount = count($page['ExhibitPageEntry']);
   
     $itempageobject = $page['ExhibitPageEntry'];
    $found=false;
    if($itemcount>0){
    for ($i=1; $i <= $itemcount; $i++) {
    if($found!=true){
        $item = $itempageobject[$i]['Item'];
        if(!empty($item)){
             while (loop_files_for_item($item)):
                            $file = get_current_file();                                            
                            //print_r($file['archive_filename']);
                            //exit;
                            if ($file->hasThumbnail()):               
                                if ($index == 0):                       
                                     $Exhibit_image = array('image'=>'/'.$file->getStoragePath('fullsize'),'title'=>item('Dublin Core','Title',array(),$item));
                                //     print_r($file->getStoragePath('fullsize'));
                                //     exit;
                                     $index=1;
                                     $found=true;
                                 endif;
                            endif;
            endwhile;
            }                   
        }
    }
    }

Followup a month later.  I've modified this concept to iterate through all the pages of an exhibit (in order) and grab the first image, which I use for the thumbnail on the exhibit browse page.

  

$imgurl = "";

foreach ($exhibit->Sections as $exhibitSection) 

{

// echo "\n   <!-- get next section -->";

if ($exhibitSection->hasPages()) 

{

foreach ($exhibitSection->Pages as $exhibitPage) 

{

// echo "\n      <!-- get next page, " . $exhibitPage->title . " -->";

for ($i = 1; $i <= count($exhibitPage['ExhibitPageEntry']); $i++)

{

$item = exhibit_builder_page_item($i, $exhibitPage);

// echo "\n         <!-- get next item, has " . count($item->Files) . " files -->";

if (count($item->Files) > 0)

{

foreach ($item->Files as $file)

{

// echo "\n            <!-- get next file, mime type: " . $file->getMimeType() . " -->";

if ($file->hasThumbnail())

{

  $imgurl = $file->getWebPath('fullsize');

  break;

}

}

}

if ($imgurl != "") break;

}

if ($imgurl != "") break;

}

}

if ($imgurl != "") break;

}
