Requirements

Documentation

Very simple gallery solution to upload images and display them in a basic gallery using Fancybox.

A gallery can be added to any page type, GalleryPage is shipped with this module as an example.

Uses customised UploadField to manage the images, allowing bulk upload of images then resorting using drag drop and editing of captions inline.

An example implementation using Fancybox2 has been provided. You are required to purchase a licence for Fancybox for commercial websites. Fancybox can be replaced easily for each page type you apply the gallery to.

Installation Instructions

Composer

1. composer require frankmullenger/gallery 1.0.*@dev
2. Visit yoursite.com/dev/build?flush=1 to rebuild the database (you may need to do this twice).

Manual

1. Place this directory in the root of your SilverStripe installation, rename the folder 'gallery'.
2. Visit yoursite.com/dev/build?flush=1 to rebuild the database (you may need to do this twice).

Usage

1. Create "Gallery page" in the CMS
2. Edit the gallery page and go to "Gallery" tab
3. Drag images into the "Drop" area
4. Edit caption for images
5. Drag and drop images to re-order them

Extended usage

You can make any page type a gallery by applying the extensions in this module to a page type. Using GalleryPage as an example:

Create a page type

Including Javascript in your controller to display the images in your gallery and a DataObject representing the join table. Because we are applying an extension with a many_many Images component you will need a DataObject {PageType}_Images to represent the join. This object requires Caption and SortOrder fields.

<?php

class GalleryPage extends Page {

}

class GalleryPage_Controller extends Page_Controller {
	
	public function init() {
		parent::init();

		Requirements::javascript('gallery/javascript/jquery-1.7.1.min.js');
		Requirements::javascript('gallery/javascript/jquery.fancybox.js');
		Requirements::javascript('gallery/javascript/GalleryPage.js');

		Requirements::css('gallery/css/jquery.fancybox.css');
	}
}

class GalleryPage_Images extends DataObject {
	
	static $db = array (
		'PageID' => 'Int',
		'ImageID' => 'Int',
		'Caption' => 'Text',
		'SortOrder' => 'Int'
	);
}

You may need to run /dev/build twice during this process to ensure the join object is created correctly.

Create a template

Using the GalleryPage.ss layout template as an example, loop through the ordered images and display them with necessary markup for your lightbox Javascript.

<% loop OrderedImages %>
	<a class="fancybox" data-fancybox-group="gallery" href="$Filename" title="$Caption">
		$SetSize(250,250)
	</a>
<% end_loop %>

Apply the extension

Apply the extension to the page type in a config yaml file:

GalleryPage:
  extensions: 
    - 'Gallery_PageExtension'
