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”]

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:

The shortcode is [file]. It will not function if it is not provided a file ID.

Options:

id (required): specify the ID number of the file you wish to retrieve; see below for instructions on how to find the ID number. For example, to get the file with the ID of 362: [file id=362]

The shortcode is [featured_exhibits]. Without additional options, it will randomly return one exhibit from all of the ones marked as featured.

Geolocation

The geolocation shortcode will create a map of items based on parameters it is given.

The shortcode is [geolocation]. Without any additional parameters, it will return a map of all items that contain geolocation data, limited by the records per page as set in the Geolocation plugin configuration.

Options

fit: specify whether to allow google map to automatically center and zoom the map to fit all of the markers. This is on by default.

To manually specify the map/location zoom, use the following options. Note, to use these options, fit must be set to ‘0’ or ‘false’.

lat: specify the latitude of the map’s initial center point, in degrees. Must be between -90 and 90.

lon: specify the longitude of the map’s initial center point, in degrees. Must be between -180 and 180

zoom: specify the initial zoom level of the map. 0 is the most zoomed out.

If any of lat, lon, or zoom are not specifically set, and ‘fit’ is set to 0 or false, the settings from the Geolocation plugin configuration page will be used.

type: specify the type of google map that appears. Defaults to the setting from the Geolocation plugin configuration page.

Options:

• roadmap - displays the road map view
• satellite - displays Google Earth satellite images
• hybrid - displays a mixture of road map and satellite views
• terrain - displays a physical map based on terrain information

collection: limits the map’s items to those from a specific collection, using the collection ID number. Only one collection may be specified. For example: [geolocation collection=5]

tags; limits the map’s items to those from a specific tag. Multiple tags can be entered, separated by a comma, and without any spaces. For example: [geolocation tags=baseball,math]

height set the map height. Can be set in pixels or percentages, but requires specification with either px or %; defaults to 436px. For example: [geolocation height=300px] or [geolocation height=50%]

width: set the map width. Can be set in pixels or percentages, but requires specification with either px or %; defaults to 100%. For example: [geolocation width=200px] or [geolocation width=75%]

Examples

To print a map of all geotagged items, simply use: [geolocation]

For a map that gets all of the items from your first collection, that are also tagged ‘baseball’. Ex. [geolocation collection=1 tags=baseball]

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.

speed sets the speed for the scrolling animation. May be “fast”, “slow”, or a time in milliseconds. Default is 400. For example: [carousel speed=slow] or carousel speed=500]

autoscroll: setting autoscroll=true will make the items automatically scroll interval. When autoscroll is on, interval sets the interval between scrolling in milliseconds. Default is 3000. For example: [carousel autoscroll=true interval=700]
