Hmm I’m confused why this works, because
And your plugin
add_action( 'wpdc_after_webhook_post_update', function( $topic_ids ) {
foreach ( (array)$topic_ids as $topic_id ) {
delete_transient( 'wpdc_comment_html_' . $topic_id );
}
}, 11 );
Aren’t you mixing up the (Wordpress) $post_id
s passed to the action with the (Discourse) topic_id
that serves as the transient key ?
I would expect your plugin to look like this
add_action( 'wpdc_after_webhook_post_update', function( $post_ids) {
foreach ( (array)$post_ids as $post_id ) {
$topic_id = get_post_meta( $post_id, 'discourse_topic_id', true );
delete_transient( 'wpdc_comment_html_' . $topic_id );
}
}, 11 );
OTOH you’re saying this works?
