I am trying to make a single page where users can choose to subscribe or unsubscribe to their forums (see https://bbpress.org/forums/topic/manage-subscriptions/). I’m pretty new to php/java, so please excuse me if this is obvious.

Basically, I have 3 forums (79, 80, 81). I have a button for each forum. When the user clicks a button, I use AJAX to run a php script. The php script is used to either subscribe or unsubscribe the user depending on whether they are already subscribed or not.

My problem is that when a user is subscribed, I’m not able to remove their subscription, and vice versa. When I click a subscribe button, the php code executes, it is able to determine if the user is subscribed, and the if statement executes properly. My problem is that bbp_add_user_subscription and bbp_remove_user_subscription return false every time.

Any help is greatly appreciated. The PHP and java script are below.

<?php
if (isset($_POST[‘action’])) {
$forum = $_POST[‘action’];
$forumint = 0 + $forum;
$subs=bbp_is_user_subscribed_to_forum($user_id,$forum);
if($subs==false) {
//if user not subscribed, then subscribe
$add=bbp_add_user_subscription($user_id,$forumint);
}
else {
$rmv=bbp_remove_user_subscription($user_id,$forumint);
//do_action(‘bbp_remove_user_subscription’, $user_id, $forumint)
}
echo ‘forum ‘;
var_dump ($forum);
echo ‘subscribed ‘;
var_dump ($subs);
echo ‘add ‘;
var_dump ($add);
echo ‘remove ‘;
var_dump ($rmv);
echo ‘foruminteger ‘;
var_dump ($forumint);
exit;
}
?>
<?php

<!– initiate all buttons –>
<button id=”790″ class=”button” onclick=”Subscriber(‘790’)”>Subscribe</button><br><br>
<button id=”800″ class=”button” onclick=”Subscriber(‘800’)”>Subscribe</button><br><br>
<button id=”810″ class=”button” onclick=”Subscriber(‘810’)”>Subscribe</button><br><br>

<!– change button text on load based on user subscription –>

<script>
$( document ).ready(function() {
$( “.button” ).click(function() {
var ForumID = $(this).attr(“id”)/10;
$.ajax({
//url: ”, // url is empty because I’m working in the same file
data: {‘action’: ForumID},
type: ‘post’,
success: function(result) {
alert(“action performed successfully”); //this alert is fired
$(‘div#result’).text(‘Button clicked: ‘ + result);
}
});
});
});
</script>

EDIT:
Also tried bbp_remove_user_forum_subscription and bbp_add_user_forum_subscription with same results.

As I understand it, it should return true if the user was subscribed/unsubscribed.

sorry, one more edit to hopefully help. With the script below, it does not subscribe or unsubscribe from the forum, but when I execute the code and check my subscriptions page (from profile), the titles of the subscribed forums are removed, but the row for the forum remains (ie. when I click subscribe, my subscriptions page shows titles, when I click unsubscribe, the subscriptions page does not show the title for the forum I tried to unsubscribe to, but it shows the number of topics, posts, etc.).

<?php
if (isset($_POST[‘action’])) {
$forum = $_POST[‘action’];
$forumint = 0 + $forum;
$user_id = bbp_get_user_id();
$subs=bbp_is_user_subscribed_to_forum($user_id, $forum);
if($subs==false) {
//if user not subscribed, then subscribe
$add=bbp_add_user_forum_subscription( $user_id, $forumint );
$add2=bbp_add_user_subscription( $user_id, $forumint);
}
else {
$rmv=bbp_remove_user_forum_subscription( $user_id, $forumint );
$rmv=bbp_remove_user_subscription( 0, 79 );
$rmv2=bbp_remove_user_subscription( $user_id, $forumint);
}
echo ‘forum ‘;
var_dump ($forum);
echo ‘subscribed ‘;
var_dump ($subs);
echo ‘add ‘;
var_dump ($add);
echo ‘remove ‘;
var_dump ($rmv);
echo ‘foruminteger ‘;
var_dump ($forumint);
echo ‘userid ‘;
var_dump ($user_id);
exit;
}
?>

Ok, I’ve been working at this all day (really several weeks) and here’s what I learned.

bbp_add_user_forum_subscription requires user ID which must be obtained by doing

$user_idd = bbp_get_user_id(0,FALSE,TRUE);

these will not work:

$user_idd = bbp_get_user_id()
$user_idd = bbp_get_user_id(0,TRUE,FALSE)

(note that I changed the variable from $user_id so as to not double define)

This works. The working php code is below.

<?php

if (isset($_POST[‘action’])) {
$forum = $_POST[‘action’];
$forumint = 0 + $forum;
$user_idd = bbp_get_user_id(0,FALSE,TRUE);
$subs=bbp_is_user_subscribed_to_forum($user_idd, $forum);
if($subs==false) {
//if user not subscribed, then subscribe
$add=bbp_add_user_forum_subscription( $user_idd, $forumint );
}
else {
$rmv=bbp_remove_user_forum_subscription( $user_idd, $forumint );
}
exit;
}
?>

I am glad that you seem to have this working now. 🙂
