Combine Galleries

Description

This plugin gives you the ability to use standard WordPress galleries and taxonomies to organize and reuse your images.

Let’s say you’re a builder and you post all your jobs on your site and include an image gallery with each post. Now, suppose you want to display all your job images on a single portfolio page. What’s the easiest way to do that? Use the following:

[combine-galleries]

Suppose you build patios, decks, and enclosures. Now, suppose you want to display all your job images, grouped by job type, on a single portfolio page. Categorize your job posts (patio, deck, enclosure) and use the following:

[combine-galleries category="patio"]
[combine-galleries category="deck"]
[combine-galleries category="enclosure"]

Finally, suppose you want to create a page optimized for a specific city (let’s use Raleigh). And, on that page you want to display all your Raleigh jobs grouped by type. Tag your job posts by city and use the following:

[combine-galleries category="patio" tag="raleigh"]
[combine-galleries category="deck" tag="raleigh"]
[combine-galleries category="enclosure" tag="raleigh"]

Combine-Galleries allows you to combine and display gallery images from multiple posts based on taxonomy. The combine-galleries shortcode combines and displays image galleries from posts that match the categories and/or tags you specify. You don’t need to categorize or tag your images, just the posts. If you just want to display all gallery images on a single page, you don’t need to categorize or tag anything.

Supports custom types. Compatible with the WordPress gallery shortcode and WordPress gallery plugins and viewers. Quickly and easily create galleries for your archive pages. See usage examples and options below…

Usage

There are several options that may be specified using this syntax:

[combine-galleries option1="value1" option2="value2"]

You can also print a gallery directly in a template like so:

<?php echo do_shortcode('[combine-galleries option1="value1"]'); ?><h3>Options</h3>-----------------------------------------------------

Supported options are listed below. All options are, well, optional. You are not required to provide any options. For example, “[combine-galleries]” will work just fine and will display all gallery images from every post and page on your site. Default option values are used when options are not specified.

type
Comma delimited list of post types from which to display images. Custom types are supported.

Default = “page,post”.

category
Comma delimited list of categories used to filter posts. If more than one category is specified, the default behavior is to AND the categories together. For example, if category=”featured,decks” then only images from posts categorized as both “Featured” and “Decks” will be displayed. Category values are case-insensitive. If no category is specified then no filter is applied. By default, all categories are included.
tags
Comma delimited list of tags used to filter posts. If more than one tag is specified, the default behavior is to OR the tags together. For example, if tag=”raleigh,durham,chapel hill” then images from posts tagged as “Raleigh” or “Durham” or “Chapel Hill” will be displayed. Tag values are case-insensitive. If no tags are specified then no filter is applied. By default, all tags are included.
taxonomy_join
Specify the boolean operator used to join multiple taxonomies, i.e. categories and tags. Combine-galleries does not support custom taxonomies… yet. The default boolean operator used to join multiple taxonomies is AND. For example, if category=”Patios” and tag=”Denver” then, by default, only images from posts categorized as “Patios” AND tagged as “Denver” will be displayed. Bool operators include:
  • AND (Default)
  • OR
category_join
Specify the boolean operator used to join multiple categories.
  • AND (Default)
  • OR
tag_join
Specify the boolean operator used to join multiple tags.
  • AND
  • OR (Default)
orderby
Specify the order in which galleries are combined. Order of galleries is based on their post. The default is post_date.
  • ID – order by post ID
  • post_author – order by post author
  • post_title – order by post title
  • post_date (Default) – order by post date
  • comment_count – order by post comment count
order

Specify the sort order of gallery posts. ASC or DESC (Default). For example, to sort by post ID from biggest to smallest:

[combine-galleries orderby=”ID” order=”DESC”]

limitposts
Limit the number of posts. By default there is no limit.
limitpostimages
Limit the number of images displayed per post. By default there is no limit.
columns

specify the number of columns. The gallery will include a break tag at the end of each row, and calculate the column width as appropriate. The default value is 3. If columns is set to 0, no row breaks will be included. For example, to display a 4 column gallery:

[combine-galleries columns=”4″]

size
Specify the image size to use for the thumbnail display. Valid values include:
  • “thumbnail” (Default)
  • “medium”
  • “large”
  • “full”
  • Any additional image size registered with add_image_size.

The size of the images for “thumbnail”, “medium” and “large” can be configured in WordPress admin panel under Settings > Media. For example, to display a gallery of medium sized images:

[combine-galleries size="medium"]

Advanced Options

itemtag
the name of the XHTML tag used to enclose each item in the gallery. The default is “dl”.
icontag
the name of the XHTML tag used to enclose each thumbnail icon in the gallery. The default is “dt”.
captiontag

the name of the XHTML tag used to enclose each caption. The default is “dd”. For example, to change the gallery markup to use div, span and p tags:

[combine-galleries itemtag=”div” icontag=”span” captiontag=”p”]

link
Specify where you want the image to link. If this option is not specified or if no value is given, the image links to the attachment’s permalink. Options:
  • “file” – Link directly to image file
  • “none” – No link

Ignored WordPress Gallery Option

id
specify the post ID. combine-galleries ignores the id option. The design goal of combine-galleries is to combine and display images from multiple posts based on taxonomy. The id option is used to display images from just one specific post. If you need to display images from a single post then the gallery shortcode is best.

Installation

Upload the plugin to your blog and Activate it. Now you are ready to use the combine-galleries shortcode. To test your installation,
create a new post, add the following shortcode to the body of your post, and preview:

[combine-galleries limitposts=”50″ type=”page,post” orderby=”post_date” order=”desc”]

This test should display all WordPress gallery images from your 50 most recent pages/posts.
