Hi,

The best way to do this is to use our purge API

LiteSpeed_Cache_API::purge_post($id)

you need to integrate this onto function of the “Best answer” button.

Best regards,

Can you please give me an example of how this can be done, please ?

Hi @dallass, do you know the page ID when you clicking the “Best Answer” button? Also, could you share the PHP code sample which triggers by the button click?

Hi,

Yes, the page ID it is known.

I put here https://pastebin.com/QXzw3jZu the content of the file.
I think you have to check from line 1601 to 1654.

Thanks for the update. According to the JS code, if you click the button, it will make a post request to WordPress.

Firstly you need to find out the action value on post request data: { action : 'wpqa_'+type... }, then add these rows to your theme’s functions.php:

if ( $_POST[ 'action' ] === 'THE_ACTION_VALUE' ) {
	LiteSpeed_Cache_API::purge_post( 'THE_POST/PAGE_ID' ) ;
}

(replace THE_ACTION_VALUE to the request action value, THE_POST/PAGE_ID to the page/post you’d like to purge)

Thank you for looking into this.

The programmer that I am working with it is a bit stubborn.
He said he made what you recommended, but it is still not working.

I have added this function https://pastebin.com/VCvyf4t3 in a php file (admin_ajax.php) in the theme folder.
And I have added this into functions.php

add_action("wpqa_after_remove_best_answer","discy_child_after_best_answer");
add_action("wpqa_after_choose_best_answer","discy_child_after_best_answer");
function discy_child_after_best_answer($post_id) {
LiteSpeed_Cache_API::purge_post($post_id);
}

‘

I would appreciate if you could find the time to have another look.

If you have a hook on remove and choose the best answer this should able to work, what is the problem you facing now?

The cache it is not cleared for that post.

So:
– without cache, you see the best answer.
– with cache, you do not see it (as the page was cached before the best answer was choosed)

Can you confirm the $post_id parameter from discy_child_after_best_answer() is the post you want to purge?

Yes, this is corect.

May I know does these two actions wpqa_after_choose_best_answer, wpqa_after_remove_best_answer on a POST request?

Sorry, but I did not understood your question.

Is it possible to have a solution ?

Could you error_log($_SERVER['REQUEST_METHOD']) on discy_child_after_best_answer() to see when it has been triggered, is it a POST or GET reqeust?

It is a post.
