CiviCRM Community Forums (archive)

OK, here's my quick-and-dirty solution.  If there's a better way to do this, I'd love to hear it...

function get_civicrm_image($id, $dimensions=array(200,200)) {
civicrm_initialize();
require_once('api/File.php');

// get the file details
$file = array_shift(crm_get_file(array('id'=>$id)));
$filename = $file['uri'];

$root = $_SERVER['DOCUMENT_ROOT'];
$file_ext = strrchr($filename, '.');
$file_base = substr($filename, 0, 0 - strlen($file_ext));
$old_path = $root . '/' . file_directory_path() . '/civicrm/custom/' . $filename;
$new_file = file_directory_path() . '/civicrm/custom/' . $file_base . '_' . $dimensions[0] . 'x' . $dimensions[1] . $file_ext;
if(!file_exists($root . '/' . $new_file)) {
image_scale_and_crop($old_path, $root . '/' . $new_file, $dimensions[0], $dimensions[1]);
}
return $new_file;
}

Then I call it from my view template like so:

$img_uri = url(get_civicrm_image($fields['image_1']->content, array(300, 200)));

You'll need to know the custom field ID of the image (in this case "image_1") in order to call the function.  This can be found in the Theme information section of the view -- for instance  "Field CiviCRM Custom: Event Details: Image (ID: image_1)".

I'm assuming that image_scale_and_crop works only in drupal ?

Yes, it's part of Drupal's core image API -- docs are here.

You need to write a custom template for your view.  You can either put the function there or in template.php for your custom theme (I recommend the latter), and then call it from the custom view template. 

I don't seem to be able to get this solution to work. I managed to get the page to stop throwing errors, but instead of an image it displays the numeral "1".

I dont think this will. We are basically just exposing the image_url in various contexts. check:

The first snippet goes in your template.php file (I'm assuming you're using a custom phptemplate theme) so that you can call it from anywhere.  Alternatively you could put it in a custom module.  The function basically takes the file ID (that number 1 that the view spits out), and gives you the path to a thumbnail of the image with dimensions you specify (creating the thumbnail if it doesn't already exist).

Second snippet goes in your custom View fields template (views-view-fields.tpl.php or views-view-fields--view-name.tpl.php, etc).  You have to replace "image_1" with the ID of your civicrm custom image field.  This info should be available somewhere in the views administration screen (I forget exactly where, and I'm not able to check right at this moment).  The second snippet basically just calls the function in the first snippet and then has Drupal turn the path into a canonical URL.  $img_uri should then contain the URL of the thumbnail, which you can print into the src attribute of an img tag.

I believe that changing the field ID is that only change you have to make, but it's possible that the solution breaks if Drupal is installed somewhere other than the domain root, in which case you'll have to fiddle with the paths in the first snippet -- in particular, this line, which can undoubtedly be rewritten to be more portable:

$root = $_SERVER['DOCUMENT_ROOT'];
If you're getting PHP errors, it's a lot easier for us to help you troubleshoot if you tell us what errors you're actually getting.

As DanilaD suggested, you can probably do something with a  Views Custom Field that requires less fiddling with the templates, but I'm not entirely familiar with how that's done, so you'll have to work that out on your own.

fm, the first thing I'd try is to make sure that your custom view block template is being loaded correctly.  I usually do that by putting some nonsense ("asdf") or whatever in it and making sure that nonsense shows up.

I'm not sure if saving the theme configuration will do anything, but you may have to clear your theme cache, which you can do with the Devel module.  Or you can paste the following at the top of your template.php file, and clear the theme cache so it'll start to take effect:

drupal_rebuild_theme_registry(); // clear theme cache on each page load
Just remember to remove it again before taking your site live, since it slows page generation times.
