PHP

Album listings pages

• Add shared album listings template on the page, enclosed in a `<div>
  • class listings album-listings
  • data-tid attribute
    • Value is the site_section representing the listings content.
    • Used for all shared AJAX scripts.
  • data-p` attribute
    • Value is the position of the first record on the page within the entire set of matching records.
    • Used for sorting.

Example:

<div class="listings album-listings" data-tid="<?=$filters->site_section->id->value ?>" data-p="<?=$filters->calc_rec_position()?>">
<? include (CMS_COMMON_TEMPLATE_DIR."content/albums/album_listings.php"); ?>
	</div>

Album details pages

~~TK~~

Javascript

Album listings pages

$(document).ready(function() {
	/* Binds AJAX functionality to album listings elements */
	$('.album-listings').galleries('bindAlbumListingsHandlers');
});

Album details pages

$(document).ready(function() {
	/* retrieves gallery content */
	$('.gallery-listings').galleries('retrieveGallery');	
});

AJAX

Assign AJAX handlers through the Content Properties CMS.

• Listings /_ajax/utils/listings.php
• Delete record /_ajax/utils/delete_record.php
• Resort /_ajax/utils/resort.php
• Update Cache /_ajax/utils/update_cache.php

PHP templates

Listings pages

This comes into play in album listings where there is an expand button for each of the albums which reveals the album's gallery.

Album details and edit pages

PHP include that inserts the gallery container element into the page. It allows for either default listing content, or custom gallery listings content:

<? include (CMS_COMMON_TEMPLATE_DIR."forms/images/gallery_listings_container.php"); ?>

Image rollovers

See Image Rollovers (Poshytip)

Image lightbox

Markup

• Surround thumbnail <img> element in <a> tags with the following attributes:
  • href="javascript:void(0)" rel="nofollow"
  • class="img-details-link"
    This is the selector used to assign the onclick handler.
  • data-id="[IMAGE_LINK_ID]"
  • data-tid="[GALLERY_SECTION_ID]"
  • data-op="view" or data-op="details"
    This allows the jQuery handler to retrieve the correct AJAX script to call to retrieve the details dialog content.
• Note that it doesn't seem to work having this link around the preview image. I.e. it's not immediately apparent that it's possible to click on the tooltip preview of the image to open up a full-sized version of the image in a lightbox.

JavaScript

• $('img-details-link') onclick handler opens a dialog containing the full-resolution version of the image.
• onclick handler defined in $.galleries('bindAlbumListingsHandlers')
• The onclick handler invokes $.formDialog('open', {dialogClass, 'gallery-dialog'})

CMS

• Details URI: /_ajax/images/image_details.php
  This returns markup containing the full-resolution version of the image to be displayed in the lightbox dialog.

Inserting an "add image" button

Markup

<button class="add-img-btn" data-id="<?=$img->id->value?>" data-pid="<?=$input->id->value?>" data-tid="<?=$img->type_id->value ?>" title="add image">add image</button>

JavaScript

$('.add-img-btn', $p)
.iconButton('addchild')
.on('click', methods.editImage); /* "methods" in the context of $.galleries() */

The $('.add-img-btn') handler is rolled into $.galleries('bindGalleryHandlers').

AJAX handler script

The handler script is determined by section_properties.upload_uri. If no value is found in that column, the code falls back on section_properties.edit_uri.

That page will expect a combination of values to be passed in via the id, pid, and tid arguments. Only tid (type id) is strictly required. pid (parent id) can be null in cases when creating a new parent record and uploading images simultaneously. id (image link record id) can be null in cases when uploading a new image.

Pagination

PHP

Album listings:

include (COMMON_TEMPLATE_DIR."framework/navigation/listings_page_links.php");

JavaScript

Handlers rolled into Album listings:

$('#listings-container').galleries('bindListingsHandlers');

.alb-nav click > $.galleries('gotoAlbumPage')

Sorting

JavaScript

LITTLED.Gallery.configureSorting(parent_dom_id) which is rolled into LITTLED.Gallery.bindGalleryHandlers(parent_dom_id).

Markup

Container and sortable elements selectors are table.gallery-listings and tr.page-row or any div selector passed to LITTLED.Gallery.configureSorting() and .page-cell for the sortable selector.

AJAX handler script

Specified through with "Sections" CMS > Content Type > Sorting URI. The generic shared script is /_ajax/utils/resort.php. See Sorting Listings for more details.
