Subscribe to Double-Opt-In Comments

Mô tả

Allows readers to receive notifications of new comments that are posted to an entry, after they successfully used the mandatory double-opt-in process to verify their e-mail address.
First, the user will get an e-mail with a confirmation link, after the user has confirmed the subscription, he or she will be noticed about new comments. This reduces junk and other unwanted e-mail communication.
This plugin is based on Mark Jaquith´s “Subscribe to Comments” plugin. More information on my blog:

  • Part of the settings menu.
  • The checkbox to subscribe to a comment thread.

Cài đặt

The most used way is to use the WordPress plugin installation process in your admin panel. Just search for the plugin name and click “Install”. After that, you can configure the plugin within its settings page.

Another, manual, way would be:

  1. Upload all files to the “/wp-content/plugins/” directory
  2. Activate the plugin through the “Plugins” menu in your WordPress admin panel
  3. Set settings via “Settings” menu in WordPress
  4. Ready, steady, go 🙂

Hỏi đáp

What do I need to know regarding the GDPR / DSGVO?

This plugin stores the following information additionally to the regular WordPress comment data:
– flag if the user has received a doube-opt-in e-mail,
– flag if the user successfully subscribed,
– anonymous hash to identify the double-opt-in e-mail.

This plugin also uses cookies to:
– check if the user has commented on a blog post with a specific e-mail address (Name: comment_author_email_, Lifespan: stored for 1 year),
– check if the user has checked or unchecked the double-opt-in checkbox for a blog post (Name: subscribe_checkbox_, Lifespan: stored for 1 year),
– optionally if used, check whether the feature “subscribe to a blog post without commenting” was used by the user (Name: comment_withoutCommentToken_, Lifespan: stored for 3 days).

Hint: WordPress, by itself, stores the IP address of the user commenting! You have to ensure that this personal information is handled according to the law of your country!

How can I change the place of the subscription checkbox?

Use this code (within the loop) in your template file, to change the place of the checkbox: <?php show_subscription_checkbox(); ?>

Can people subscribe manually without commenting?

Yes, just place this code snippet in your template (outside the comments form): <?php show_manual_subscription_form(); ?>

I use as my website hoster and I cannot send e-mails via this plugin

The public managing part for the subscriber looks a little bit like 1990. A total different design as the main site. Some PHP Count Error on the managing site. Different other errors if u delete a subscription. Don’t know, have the developer test his own work ? Why u haven’t implemented the managing part as a part of the site? Why u have chosen the own, creepy one ? The Backend Part work as expected, but the other….

Tested a bunch. Best plugin I’ve found to subscribe people to comments. Simple to set up. Worked out of the box. I donated 3 euros. Keep up the good work, Etienne

I installed the plugin and tested it out. I got an error message when trying to manage subscriptions, saying that “You may not access this page without a valid key”. I asked for support on this and have had no replies from the developer at all. Just other users having the same problems. Having said that, it does seem that when a subscriber receives a follow up to the comments to which they subscribe, the email they receive contains a link to manage subscriptions and that does work, it seems, at least. Due to lack of support by developer and the confusing message to the user, it can’t have more than 2 stars.
