The Gallery feature allows you to add one or more image galleries to your posts and pages using a simple Shortcode. Since WordPress 2.5 and up until 3.5, the gallery shortcode was commonly used in its most basic form:
[gallery]
Following 3.5, gallery shortcodes includes the image IDs by default. Like this:
[gallery ids="729,732,731,720"]
It's important to note that this style of gallery shortcode is not new to 3.5, previously we could use the include attribute. However it is much easier to generate and manage with the new Media Workflow introduced in 3.5.
Specifying IDs in your shortcode allows you to include images in your gallery that aren't necessarily "attached" to your post — that is to say, not uploaded from within your post or page. This flexibility allows you to create and embed any number of galleries containing any number of images!
Note: If you choose to just use the "barebones" version of the [gallery] shortcode in your post or page, only images that are "attached" to that post or page will be displayed.
Usage
There are several options that may be specified using this syntax:
[gallery option1="value1" option2="value2"]
You can also print a gallery directly in a template like so:
This works too:
post_parent ] . '"]';
print apply_filters[ 'the_content', $gallery_shortcode ];
?>
Options
The following basic options are supported:
orderby specify how to sort the display thumbnails. The default is "menu_order". Options:- menu_order - you can reorder the images in the Gallery tab of the Add Media pop-up
- title - order by the title of the image in the Media Library
- post_date - sort by date/time
- rand - order randomly
- ID
[gallery order="DESC" orderby="ID"]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:
[gallery columns="4"]id specify the post ID. The gallery will display images which are attached to that post. The default behavior, if no ID is specified, is to display images attached to the current post. For example, to display images attached to post 123:
[gallery id="123"]size specify the image size to use for the thumbnail display. Valid values include "thumbnail", "medium", "large", "full" and any other additional image size that was registered with add_image_size[]. The default value is "thumbnail". 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:
[gallery size="medium"]
Some advanced options are available:
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".captiontagthe 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:[gallery itemtag="div" icontag="span" captiontag="p"]linkSpecify where you want the image to link. The default value links to the attachment's permalink. Options:
- file - Link directly to image file
- none - No link
[gallery ids="729,732,731,720"]0includecomma separated attachment IDs to show only the images from these attachments.
[gallery ids="729,732,731,720"]1excludecomma separated attachment IDs excludes the images from these attachments. Please note that include and exclude cannot be used together.
[gallery ids="729,732,731,720"]2
Developers - Things to consider
The default expected behavior for a gallery that has no explicit IDs stated is to add all images that have the post as post parent assigned. In other words, add all images that were uploaded using the "Add media" button/link on this post edit screen. Keep in mind that this as well means that every attachment added to that post later on will be interpreted to be part of the gallery. No matter if it was displayed as plain attachment or not.
This should be the default fallback if no argument were provided: ...lorem [gallery] ipsum...
[gallery ids="729,732,731,720"]3
And stop using extract[] on shortcode_atts[] [or anywhere else]. IDEs are not able to backtrace that.
