I have an AddPhoto.inc that writes to an xml file the data I need for a java applet. There is a link under the photo that runs the below inc file and redirects back to the page I just left.

Everything works to write to my file, except I need additional information. I've tried the fetchThumbnailsByItemIds to help me get the thumbnial ID and have tried to use the generate url function, but I can't seem to get any of this to work. I've had fetchThumbnailsByItemIds working on another page, but not here, which makes me wonder if I'm not calling something I should be.

Below are my variables I am trying to write. I really could use some help finding the values for these.

Quote:
class AddPhotoController extends GalleryController {

function handleRequest($form) {
/* Check input. */
if (!is_numeric(GalleryUtilities::getRequestVariables('itemId'))) {

} else {
$picture_id=GalleryUtilities::getRequestVariables('itemId');

//Full size picture url
$high_res = "gallery/main.php?g2_view=core.DownloadItem&g2_itemId=".$picture_id;
//Title of picture
$title = "";
//Full size image size
$size = "";
//Full Size resolution width
$res_width = "";
//Full Size resolution height
$res_height = "";
//800x600 mid size image url
$screen = "";
//Thumbnail url
$thumb = "";

//Write variables to my xml file

}
$redirect = $status = $error = array();
$results['return'] = 1;
$results['redirect'] = $redirect;
$status = "Added to Tray";
$results['status'] = $status;
$results['error'] = $error;

return array(null, $results);
}
}

I've tried mediaBlock.php earlier. I get the below error when I copy the getThumbUrl to my inc file.

Quote:
Fatal error: Call to undefined function getThumbUrl()...

so you called it like:

list($ret, $item) = GalleryCoreApi::loadEntitiesById($picture_id, 'GalleryItem');
    if ($ret) {
        print "Error loading item:".$ret->getAsHtml();
    }
list($thumbUrl, $thumbWidth, $thumbHeight) = AddPhotoController::getThumbUrl($item);

OK, that helped a lot. I am trying to generate the url for the full sized picture. I am using getView, but all it retrieves is "h".

with nearly every function in my script you need to pass an $item object which we loaded here: list($ret, $item) = GalleryCoreApi::loadEntitiesById($picture_id, 'GalleryItem');
you can pass the same object around to retrieve your desired output.

If you're trying to output an xml feed check function displayMediaRss

Thank you for your help, I've acomplished more in the last few hours than I have all day on this. I was looking through the list and did not find a function to get the file size. If you can point me in the right direction, I think I can write the function.

I also need to get an 800 x 600 view, and I saw the resize function, but I'm not sure how to make it work. Any thoughts?

Thanks again

hmmm... size I believe is simply $item->getSize(); from GalleryDataItem.
I don't believe that resize function is actually used, it returns a string of views, not what you want.
but function getBestImageId would.
you'd need to change:

if (isset($_REQUEST['g2_maxImageHeight'])) {
        $maxImageHeight = $_REQUEST['g2_maxImageHeight'];
    }
    if (isset($_REQUEST['g2_maxImageWidth'])) {
        $maxImageWidth = $_REQUEST['g2_maxImageWidth'];
    }

to:

        $maxImageHeight = 600;
        $maxImageWidth = 800;

and:

usort($potentialImages, "byWidth");

to:

usort($potentialImages, array('AddPhotoController', 'byWidth')););

and you would also need to include
function byWidth as well
