Comment Reply Email Notification

Description

This plugin allows visitors to subscribe to get answers to their comments via e-mail.

Warning

This plugin uses the “wp_insert_comment” hook, therefore, everytime a comment is created, a notification is likely to be sent. If you are importing comments into your blog, it’s a good idea to disable this plugin.

Sending e-mails does not work?

The plugin uses the standard WordPress e-mail function. If you have problems getting e-mails sent, you might try using plugins like https://wordpress.org/plugins/wp-mail-smtp/ to improve sending e-mails from your site.

Customizing the layout of the checkboxes

The label next to the checkboxes don’t contain a whitespace. Depending on your theme you might want to add a custom style like this to get a space between the checkbox and the label:

input#cren_subscribe_to_comment, input#cren_gdpr {
  margin-right: 0.5em;
}

The plugin does not add this style be default as it depends on your theme if this is neccessary.

Customizing the email template

To customize the email template, copy the “templates” folder to your theme folder (a child theme should be used to avoid losing the custom templates when the theme is updated). The plugin will look for templates on the “/wp-content/themes/[THEME]/templates/cren/” folder; if a custom template is not found, then it will fallback to the default template.

Changing the subscription checkbox label

The checkbox label can be changed with the cren_comment_checkbox_label filter. This way you can update the text to your taste and keep the plugin updated.

Changing the GDPR checkbox label

The GDPR checkbox label can be changed with the cren_gdpr_checkbox_label filter. This way you can update the text to your taste and keep the plugin updated.

Modifiying HTML output

Using the filters cren_gdpr_checkbox_html and cren_comment_subscribe_html you can modify the HTML output of the checkboxes if needed.

Example:

add_filter('cren_gdpr_checkbox_html', function(string $html_output, string $label_text, string $privacy_policy_url): string {
    $html_output = '<div class="comment-form-gdpr-consent form-check mb-3"><input id="cren_gdpr" class="form-check-input" name="cren_gdpr" type="checkbox" value="yes" required checked><label for="cren_gdpr" class="form-check-label">' . $label_text . '<span class="text-danger fw-bold">*</span> (<a href="' . $privacy_policy_url . '" title="Privacy Policy" target="_blank" rel="internal">Privacy Policy</a>)</label></div>';

    return $html_output;
}, 10, 3);

add_filter('cren_comment_subscribe_html', function(string $html_output, string $label_text, bool $checked_default): string {
    $checked = $checked_default ? 'checked' : '';
    $html_output = '<div class="comment-form-email-consent form-check mb-3"><input id="cren_subscribe_to_comment" class="form-check-input" name="cren_subscribe_to_comment" type="checkbox" value="on" ' . $checked . '><label for="cren_subscribe_to_comment" class="form-check-label">' . $label_text . '</label></div>';

    return $html_output;
}, 10, 3);

  1. Extract the contents of the package to the /wp-content/plugins/comment-reply-email-notification directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress

I just wanted a simply solution to allow people to get email notifications. This works great. I tested the one with more downloaded and like this one better. It just works. I wish it was easier to edit the email template and design, but that isn’t a big deal. Using it on DIVI blog and it works great for me. Takes a few minutes to send but maybe that is my email server not the plugin. Check it out in action here: mattenser.me/blog/is-belief-in-god-reasonable/ Thanks for the great plugin!

I tried it with a test comment using an actual email address and then replied to the comment using another actual email address but did not receive any email on the first one. Any idea how this could work?

Not sure if this works with previous WP version but it does not work with WP 6.3. If you set your WP discussion settings to “email me whenever anyone posts a comment” — that should send an email to the author. If this plugin is then installed, the email will go to the site admin address and no email will be sent to the post author. When I removed the plugin, the Wordpress Settings worked as expected and notifications went to the post author.

This plugin seems like a viable replacement to Subscribe to Comments Reloaded.
