Read Later Buttons

Read Later Buttons provides a widget and a shortcode for displaying “read later” buttons for the popular apps Instapaper, Pocket, and Readability. It can also display a Send to Kindle button if that plugin is installed, letting your users send your content to their e-reader to enoy when they have the time.

This plugin is designed to function well and look good without much fuss, but it also provides a shortcode and filters so you can control how the buttons look & work.

Shortcode

Use the [read_later_buttons] shortcode to render buttons for every one of the supported services. You can also include the names of one or more services (i.e. [read_later_buttons instapaper pocket] ) to just get those buttons. Valid service names are kindle , instapaper , pocket , and readlater .

The shortcode can also display an estimated reading time if you include the “time” parameter ( [read_later_buttons time] ). The reading time can be combined with service names ( [read_later_buttons time instapaper] ) and the time will render above the buttons. When including the time estimate, the plugin won’t display all the buttons by default. You need to include the “all” parameter (i.e. [read_later_buttons time all] ) in that case. Also, the shortcode has to be used inside “the loop” in order to calculate a time — in other words in a page, post, or the appropriate parts of your theme template.
