Subscribe to Comments 2.1

Subscribe to Comments 2.1 is a plugin that allows commenters on your blog to check a box before commenting and get e-mail notification of further comments. It is one of the most popular WordPress plugins out there for the simple reason that it helps foster a community around your blog by encouraging commenters to come back and stay engaged in the dialog.

Features

  • Rudimentary security
    • Users cannot enter a random e-mail into the subscription manager and modify someone else’s subscriptions
    • In order to modify subscriptions, users need to use a special link, given in notification e-mails, and printed in the comments form as long as they have their comment cookie
  • Recognition of subscription status
    • Unsubscribed users see the “subscribe to comments” checkbox, but subscribed users see a “Manage your subscriptions” link
    • The author of the post is recognized by either login or comment cookie and is assumed to be subscribed to the entry (as they will receive notifications through WordPress)
  • Themeable subscription manager
    • Uses visual style of WordPress interface
    • Can be optionally accessed via “Manage” menu in WordPress
    • E-mail verification of block requests
    • Javascript “invert selection” link to check/uncheck subscriptions for mass deletion
    • “Return to the page you were viewing” link that persists at the top of the page, so that users can easily return to the post they were reading once they are done modifying subscriptions
  • Ability to let users change notification e-mail address
    • In the subscription manager, users can request that their notification address be changed for all their subscriptions
    • Special link is sent to the old address for verification
    • Once clicked, their e-mail address will be changed instantly for all their comments
  • Easy integration into comments form
    • No modification of comments form needed for WP 1.5+ (supported themes)
    • For users who want custom placement of the checkbox/link to subscription manager, this can be done with one simple function call, placed anywhere in the comment form
  • Subscription without leaving a comment
    • By popular demand, you can now offer visitors the option of subscribing to comments on an entry without having to leave a comment themselves
    • If the reader later decides to join the conversation, their subscription continues without them having to explicitly set it
  • Customization
    • You can make the Subscription Manager that your users see use your theme’s header, footer and sidebar, using CSS to style it to fit your site
  • Internationalization
    • I’ve written Subscribe to Comments 2.1 with i18n in mind, making full use of __() and _e() functions. The domain is “subscribe-to-comments”.

Version 2.1 Update

Version 2.1 of Subscribe to Comments has a feature that people have been begging me to implement for many months: you can view the list of people who are subscribed to posts on your blog, and you can also see a list of the most “subscribed” posts. Also in this version is a new one-file install. You just put subscribe-to-comments.php in your /plugins/ directory, activate, and you’re done. This version will work on WordPress versions from 2.0.6 through 2.3.1 (highest tested).

Versions

  • 2.1.2 Fixed a few bugs that’d send bad notifications (thanks Donncha!), cleaned up some code and moved to using proper WP escaping functions
  • 2.1.1 WordPress 2.2 compatibility! Also note that support for attribute_escape() is needed, so if you get errors about that, upgrade to the latest version in your branch
  • 2.1 big update, fixing a few potential XSS holes, and misc error messages… see above for details
  • 2.0.8 XSS security fixes, hopefully fixed “+” symbols in e-mail for good
  • 2.0.7 additional “funky e-mail” fixes
  • 2.0.6 support for e-mail addresses with “+” symbols, option to disable CSS “clearing”
  • 2.0.4 potential security bugs, better WP 2.0 capabilities compat

    Thanks for making it so easy to install!

    2 easy questions…

    1) to embed the Manage Subscriptions link the comment box (just like with this blog), you say to use [manager_link]. I tried the following but it just shows it as code/text on my page:

    [manager_link]Manage your subscriptions.[/manager_link]

    What should it literally look like?

    2) to have the Manage subscriptions page follow my theme, you ask for the path. Can you provide an example of from where the path should implicitly start?

    ie
    ../wp-content/themes/faketheme/ ?
    or
    /wp-content/themes/faketheme/ ?

    etc.

    On my blog I’m not the author of each article and I don’t receive the email for tell me a new comment is post.

    It’s possible for the admin to receive a email for each comment post?

    I’m trying to install Comments 2.0 and have but when I test it, all I see is a check box and no instructions. Anyone kn ow what this is all about and how to fix?

    Thanks,

  48. Hi Neil,

    Subscribe to Comments 2.1 has a bug that doesn’t work with wordpress 2.2.x that are fr*esh installs. However, it works with up*grade from wordpress 2.1.x.

    This has been an issue with many of users who falls in the former scenario.

    We hope it could be resolved soon.

    Sherman

  49. Dennis Edell says:

    I have 2 freshly installed 2.2.2 blogs, and it works fine. I did however notice that it largely depends on the THEME you pick.

    I searched hard for a theme in which the plugin would work.

  50. Ron says:

    I am using Cutline v3 or something like that and it doesn’t work with that one. Which one does it work with?
    Thanks

  51. Dennis Edell says:

    Yea, I tried all 3 cutline themes, no good. The one I use is ModernPaper-10. A simple 3column right, template. Click my link, then either of the 2 links on top to see it.

    The plugin works right outa the box, no tweaking whatsoever. I’m REALLY hoping it still works when cPanel finally installs WP 2.3 for use.
