Greetings - I'm looking to extend the Image gallery with a widget to allow displaying of x number images from a selected album

I have been able to create a function for the Calendar Module to display the Latest Events as below - where I added a select box for a Calendar event to be "featured" in the Calendar event Class

function UpcomingEvent()
   {
      Requirements::css('event_calendar/css/calendar.css');
      Requirements::javascript("event_calendar/javascript/calendar_core.js");
      return DataObject::get_one("Calendar")->upcomingEvents(1,"FeaturedEvent = 1");
   }

So I would like to create a similar function in the Image Gallery Module for a widget that allows a featured Album(s) to be displayed on any page .

Uncle Cheese - Can you point me in the direction for creating a function in the Class ImageGalleryAlbum or ImageGalleryPage similar to the upcomingEvents function in the Calendar Class?

E.g.

function LatestGallery()
   {
      Requirements::css( based on pop up mode );
      Requirements::javascript( based on pop up mode );
      return DataObject::get_one("ImageGalleryPage")->latestGalleries(1,"FeaturedEvent = 1");
   }

So need to develop the latestGalleries function

Thanks

Hi
I have tried modifying the Gallery widget for the ImageGallery Module

I created a file LatestAlbumsWidget.php
The orginal code uses a SQL call - I prefer to use a dataObject call so If anyone can assist that would be great!

Here's the code used that does return the latest pictures but what I am looking for is to be able to select the album to be featured and show latest images from that album only
- the function AlbumTitle doesn't currently work

The Template is not displaying the title or the decription of the album

LatestAlbumsWidget.php

<?php

class LatestAlbumsWidget extends Widget {
   static $db = array(
      "AlbumsToShow" => "Int",
      "ImagesToShow" => "Int",
      "ThumbnailWidth" => "Int",
      "ThumbnailHeight" => "Int"
   );
   
   static $defaults = array(
      "AlbumsToShow" => "2",
      "ImagesToShow" => "3",
      "ThumbnailWidth" => "120",
      "ThumbnailHeight" => "90"
   );
   
   function getCMSFields() {
      return new FieldSet(
         new NumericField("AlbumsToShow", _t("LatestAlbumsWidget.NTS", "Number of albums to show (0 for All)")),
         new NumericField("ImagesToShow", _t("LatestAlbumsWidget.NTF", "Number of pictures to show (0 for All)")),
         new NumericField("ThumbnailWidth", _t("LatestAlbumsWidget.THUMBWIDTH", "Thumbnail width")),
         new NumericField("ThumbnailHeight", _t("LatestAlbumsWidget.THUMBHEIGHT", "Thumbnail height"))
      );
   }
   
   function DescriptionSegment() {
      if(!class_exists("ImageGalleryAlbum")) {
         return _t("LatestGalleriesWidget.NOCLASS","You don't have the Image Gallery module installed, which is required by this widget.");
      }
      return parent::DescriptionSegment();
   }
   
   function Title(){
return _t("LatestAlbumsWidget.TITLE","Latest Events");
}

function CMSTitle(){
return _t("LatestAlbumsWidget.CMSTITLE","Latest Albums");
}

function Description(){
return _t("LatestAlbumsWidget.DESCRIPTION","Shows a list of albums that were changed most recently, and shows thumbnails of the pictures that have been added most recently to each gallery.");
}

   function Pictures() {
Requirements::css("widgets_gallery/LatestAlbumsWidget.css");
    $images_nrtoshow = (0<$this->ImagesToShow) ? $this->ImagesToShow : $this->defaults["ImagesToShow"];
    $pictures = DB::query("SELECT f.`ID`, f.`Filename`, f.`Name`, f.`Title`, a.`AlbumName` FROM `ImageGalleryItem` g LEFT JOIN `File` f ON g.`ImageID` = f.`ID` LEFT JOIN `ImageGalleryAlbum` a ON a.`ID` = g.`AlbumID` WHERE f.`ClassName` = 'ImageGalleryImage' ORDER BY g.`SortOrder` AND g.`AlbumID` DESC LIMIT 0,$images_nrtoshow;");
   $thumbnails = new DataObjectSet;
foreach ($pictures as $picture){
$picture["GalleryLink"] = Director::baseURL().$picture["Filename"];
$thumbnail = new Image($picture);
$thumbnail = $thumbnail->getFormattedImage( "PaddedImage", $this->ThumbnailWidth, $this->ThumbnailHeight);
$thumbnail->setField("GalleryLink", Director::baseURL().$picture["Filename"]);
$thumbnail->setField("Name", $picture["Name"]);
$thumbnail->setField("Title", $picture["Title"]);
         $thumbnails->push($thumbnail);
}
unset($pictures);
      return $thumbnails;
   }

   function AlbumTitle()
   {
      return $this->Pictures('AlbumID')->AlbumName;
   }
}

?>
