Read Offline

Read Offline example
I’m working on a plugin which allows you to download and read posts and pages offline in pdf, epub and mobi formats, and I need beta testers (please share this page with WordPress friends).

Please use the comments field below if you find bugs, typos etc.

Features

  • Settings page (Settings->Read Offline)
  • Read Offline widget (output shown in the image above)
  • Read Offline shortcode
  • You can download a pdf, epub or mobi file containing the current post or page (you have to add the Read Offline widget to see the download links)
  • The download filename is based on the posts slug ($post->post_name)
  • Adds meta data to the file
    • Title (PDF, ePub and mobi)
    • Author (PDF, ePub and mobi)
    • Subject (mobi)
    • Publisher (ePub)
    • Identifier (uPub)
    • Source URL (ePub)
    • Language (ePub)
  • Option: Add download links to the top and bottom of a post or page.
  • Permalink support (/read-offline/”postid”/”post-name”.”type”). I’ve written a how-to add permalink to plugins guide.
  • Option: Add a custom style to the ePub and PDF file
  • Option: Google Analytics read-offline event tracking. You can find these under Content » Events in your Google Analytics reports. Assumes you’re using the Asynchronous version of Google Analytics.
  • languages/read-offline.po for easy translation.

To-do / Wish List

Use

There are 3 ways you can add the Read Offline link

  1. At the top or bottom of each post and/or page (See Settings->Read Offline)
  2. Using the Read Offline widget
  3. Using the [readoffline] shortcode


The [readoffline] shortcode has the following parameters

  • format=”epub”, default: format=”pdf,epub,mobi”
  • text=”Read %title offline:”, default: text=””. %title% will be replaced with the post or page title
  • icononly=”true”, default=”false”

Examples

  • [readoffline] is the same as [readoffline text="" format="pdf,epub,mobi" icononly="false"]
  • [readoffline text="Download %title%:" format="epub"]

    When I use Read Offline with the Twenty Eleven theme, the print icons appear at the top of ALL pages (I selected top of page as the location in settings) but not at the top of posts. Is there a way to have 1) The print icons appear only on pages I select and 2) Also appear on posts I select. If there is code I need to modify could you provide the code and specify the (child) files that need to be edited. Thanks, Jerry

      You can run plugin the in your template (it must be activated first) by doing:

      There’s not support for styling yet and there’s no pro version yet.

    Hi,

    With the new versions of Cbox theme (1.0.5 and 1.0.6), the read later dowload pdf line appears in the caption of the slides in the slider. Increasing the width of the caption banner see here: http://dev.commonsabundance.net/

    This did not occur with Cbox 1.0.4.

    Is there anything to do on your end? The devs at Cbox suggest I deactivate your plugin…

    Thanks

    Hi,

    Impressive plugin with a lot of quality. Congrats, and thank you !
    Two questions please :
    - I didn’t understand how to use meta. Could you explain a bit more please? Could it be used to have some king of template (ex: always have site URL from which the pdf has been created. As I understand, PDF are a bit anonymous right now).
    - Is there a quick way to make the plugin compliant with custom posts? My site has plenty and I can’t generate PDF for them ;-(

    Thank you very much once again for the quality of plugin,
    Cédric.

      Hi Cédric,

      I’m working on the next version which will support custom post types + meta information. Not sure when it will be ready.
