Shortcodes

Shortcodes work in text fields in specific places on Omeka Classic sites: on Simple Pages, and in the text fields of Exhibit BuilderExhibit Page blocks.

Note: This page is a user’s guide to shortcodes. For developer documentation, see Working with Shortcodes on Omeka’s Read the Docs site.

For shortcodes for Plugins, see the Plugin Shortcodes

General

Shortcodes can be added into html text fields. The general syntax is [shortcode key=value]

Values can be wrapped in single or double quotes, making the following variations valid as well: [shortcode key='value'] or [shortcode key="value"] Please note that shortcodes will not work with smart quotes.

If the shortcode results in an image display (from an item or file), the shortcode will use the Omeka default of displaying the filename or Dublin Core title as alt-text.

When using shortcodes on a SimplePage, you should not use the "HTML editor" option. Put the shortcode in the basic text field:

When using a shortcode in an Exhibit Builder block, place the code directly into the text editor:

A shortcode that leveraged all of the possible parameters would look like [geolocation lat=42 lon=117 zoom=7 type=hybrid collection=4 tags=baseball,math,oakland height=500px width=500px]

Shortcodes Carousel

Requires the Shortcode Carousel plugin.

The plugin adds a shortcode to create a carousel of items using jCarousel

The basic shortcode is [carousel].

[recent_carousel] and [featured_carousel] are shortcuts to creating a carousel of recent and featured items, respectively.

The same options available for the Items shortcode are available for the carousel, with the exception that has_image is always assumed to be true.
