fix: give session cookie prefix #3819

Bug Report

User Story

As a web host like Pantheon, we exclude sessions cookies from caching when they are prefixed according to the WP Codex cookie naming convention of wp-.

Current Behavior

Give currently names its cookies with an underscore, as in wp_give_session. This means that Give users on Pantheon cannot see their donation confirmation receipt successfully but see the email access or login form instead.

$this->cookie_name = apply_filters(
'wp_give_session_' . COOKIEHASH, // Cookie name.
'session' // Cookie type.

Expected Behavior

I expect the Give cookies to follow the WP Codex naming convention so that cookies are named more predictably for hosts.

Bug Type

  • This bug describes functionality that once worked as expected in version X.X.X.
  • This bug describes functionality that never worked as expected.
  • I am not sure whether this functionality ever worked as expected.

Steps to Reproduce

  1. Attempt a donation on this page hosted on Pantheon: -- Credentials to the site can be provided to Give devteam via Slack.
  2. Note that the donation receipt does not appear correctly.
  3. Login to the site and change the cookie name to start with wp-
  4. Attempt a new donation and note that it now DOES appear correctly.

Possible Solution

Change the cookie name with backward compatibility.

Acceptance Criteria

  • The new cookie name is reflected every time the session is created successfully
  • There are not any other dependencies on that cookie name in the plugin that might negatively impact the functioning of Give or its Addons

@mehul0810 Please look into this issue on the Pantheon server. If you need to manipulate the cookie name, you can change the coookie name on this line using the Dashboard > Plugins > Edit screen.

  • See if you can recreate the issue and fix it by using wp- instead of wp_.
  • Report whether there would be any issue with changing the cookie name to use wp- permanently going forward.
  • Report whether there are other cookies used by Give that should also be updated.

As a reference, this is the snippet we sent to customers as a workaround for this issue:

add_filter('give_session_cookie', 'my_custom_give_cookie_prefix', 99, 2);

function my_custom_give_cookie_prefix( $cookie, $session ) {
    $cookie = 'wp-give_session_' . COOKIEHASH; // Cookie name.

    return $cookie;

@mathetos @kevinwhoffman We already addressed this issue because Pantheon only allow cookies with specific prefix: #3705 (comment)

I will suggest adding support for Pantheon host in core if a user coming so often. Pantheon host defines PANTHEON_ENVIRONMENT global variable on basis of that we can set our logic:

Slack Call Summary

Participants: @mehul0810 @ravinderk
Topic: Discussion about cookies for a pantheon host
Result: I've noticed that changing cookie prefix from wp_ to wp- will make donation receipt working on pantheon. I'll make those changes in PHP as well as JS files and test it again to ensure it is working fine.

Slack Call Summary

Participants: @mehul0810 @ravinderk
Topic: Discussion about making the cookie names dynamic
Result: Ravinder suggested me to make the cookie names dynamic as using session anyone can easily change the name and there is hardcoded cookie names implemented earlier which need to be dynamic.
