Hello everyone!

I’m a new user of bbpress and I’m looking for a way for logged in users to subscribe/unsubscribe to all forums by clicking a button.

I’ve managed to do it by myself, but I’d like to know if there is an easier way to do it.

Here is the code in my loop-forums.php file:

<?php

/**
 * Forums Loop
 *
 * @package bbPress
 * @subpackage Theme
 */

// Exit if accessed directly
defined('ABSPATH') || exit;

do_action('bbp_template_before_forums_loop'); ?>

<?php
$current_user = get_userdata(get_current_user_id());

if (isset($current_user) && $current_user->ID > 0) :
  $user_subscribed_forum_ids = bbp_get_user_subscribed_forum_ids($current_user->ID);
  $forum_ids_list = array();

  while (bbp_forums()) : bbp_the_forum();
    if (bbp_get_forum_type() === 'category') :

      foreach (bbp_forum_get_subforums() as $subforum) :
        $forum_ids_list[] = $subforum->ID;
      endforeach;
    else :
      $forum_ids_list[] = bbp_get_forum_id();
    endif;
  endwhile;

  $check = sizeof($forum_ids_list) === sizeof($user_subscribed_forum_ids);
  $bbp_action = $check ? "bbp_unsubscribe" : 'bbp_subscribe';
  $label = $check ? "Unsubscribe of all forums" : "Subscribe of all forums";
  $label .= bbp_get_forum_type() === 'category' ? " of this category" : "";

  if (isset($_POST) && $_POST['action']) :
    foreach ($forum_ids_list as $forum_id) :
      $q_args = array(
        'action'      => $bbp_action,
        'object_id'   => $forum_id,
        'object_type' => 'post'
      );

      $permalink = bbp_get_forum_permalink($forum_id);
      $wp_nonce_url = esc_url(wp_nonce_url(add_query_arg($q_args), 'toggle-subscription_' . $forum_id));
      $wp_nonce_url = substr($wp_nonce_url, strlen('/'));
      $url = html_entity_decode($permalink . $wp_nonce_url);

      $ch = curl_init($url);
      curl_setopt($ch, CURLOPT_COOKIE, LOGGED_IN_COOKIE . '=' . $_COOKIE[LOGGED_IN_COOKIE]);
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
      $response = curl_exec($ch);
      curl_close($ch);
    endforeach;

    $user_subscribed_forum_ids = bbp_get_user_subscribed_forum_ids($current_user->ID);
    $check = sizeof($forum_ids_list) === sizeof($user_subscribed_forum_ids);
    $bbp_action = $check ? "bbp_unsubscribe" : 'bbp_subscribe';
    $label = $check ? "Unsubscribe of all forums" : "Subscribe of all forums";
    $label .= bbp_get_forum_type() === 'category' ? " of this category" : "";
  endif; // isset($_POST) && $_POST['action']
endif; // isset($current_user) && $current_user->ID > 0
?>

<?php if (isset($_POST) && $_POST['action']) : ?>
  <script id="prevent-form-resubmission-when-page-is-refreshed" type="text/javascript">
    // source: https://stackoverflow.com/questions/6320113/how-to-prevent-form-resubmission-when-page-is-refreshed-f5-ctrlr
    if (window.history.replaceState) {
      window.history.replaceState(null, null, window.location.href);
      document.getElementById('prevent-form-resubmission-when-page-is-refreshed').remove();
    }
  </script>
<?php endif; ?>

<?php if (isset($current_user) && $current_user->ID > 0 && !bbp_is_single_user()) : ?>
  <form action="" method="POST">
    <input type="hidden" name="action" value="<?= $bbp_action ?>">
    <button type="submit" style="color: black;"><?= __($label, 'ls') ?></button>
  </form>
<?php endif; ?>

<table id="forums-list-<?php bbp_forum_id(); ?>" class="table table-bordered forums-list">

  <thead>
    <tr>

      <th class="forum-title-column">
        <?php esc_html_e('Forum', 'ls'); ?>
      </th>

if that works, go for it 🙂

Yes, it works very well.
I would just like to know if anyone has a cleaner solution.

In the meantime, this can always be used by others.
