Limited Support
Our team is currently on holiday, so support will be limited during this period. Response times may be slower than usual, and some inquiries may be delayed.
We appreciate your patience and understanding, and we’ll resume our usual support by the end of August.
I suspect this has an easy solution but I'm banging my head and hopefully someone willing to kindly help me out.
Quick version:
Is there a wpdiscus action hook that fires after a comment has saved, that will also allow for a javascript page redirect without the "unsaved changes" popup confirmation dialog firing? I've tried wpdiscuz_after_comment_post but the page believes that there are unsaved changes no matter what I do.
Longer version with details:
I have a post called "New Topic" that I plan to use as a special spot where users can submit to any Topic based on a query_var in the URL (so ?topic_id=345 etc.)
I have a function working using the standard WP 'comment_post' action, which basically looks for the topic id, then updates the comment comment_post_ID to whatever topic post the comment should be moved to.
All that works, but I want to redirect after the comment is saved, to the topic post where the new comment has ben assigned.
PHP redirect won't work because the headers have been sent. I tried echoing javascipt with window.href= etc., and that does work, but I get the popup confirmation that there are unsaved changes on the page. I need to avoid that.
Any suggestions? Any built in redirect hooks that I can leverage maybe?
Thanks!
First solution
We may suggest you check out the wpDiscuz built-in "Redirect First Comment to" option. It's located in the Dashboard > wpDiscuz > Settings > General tab.

Another solution
wpDiscuz has a wpdiscuz_ajax_callbacks hook. You can use it to get it to work as you like:
The PHP code:
add_filter("wpdiscuz_ajax_callbacks", function ($response) {
$response["callbackFunctions"][] = "myCustomCallback";
return $response;
});
Your JS code:
window.myCustomCallback = function (response) {
if (response.success) {
//do something
}
};
Brilliant! Thank you so much, a tiny bit of fiddling and console.logging, but wpdiscuz_ajax_callbacks worked perfectly, and probably opens up answers to a whole slew of upcoming challenges. Thanks so much, really appreciate the quick and thorough answer. BTW I've already bought one paid addon, I'm sure I'll be back for more.
