== Frequently Asked Questions ==

= It doesn't work / CSS styling is bad ! =

Styling has been setup for the bbPress default theme.  
If it doesn't work for you, please try to check/override our CSS styles (bbppu.css)

= How can I filter topics to display only the unread or read ones ? =
Just add the **bbppu** arg to your [Wordpress queries](https://codex.wordpress.org/Class_Reference/WP_Query).  You can set it either to *read* or *unread*.
Of course, this works for the current logged user and will be skipped if the visitor is not logged.

Example :

`<?php
$last_unread_topics_query_args = array(
  'post_type'       => bbp_topic_post_type(), //or 'topic'
  'posts_per_page'  => 5,
  'bbppu'       => 'unread' //only unread ones
);

$last_unread_topics_query = new WP_Query( $last_unread_topics_query_args );
?>`


= How does it work? =

*bbPress Pencil Unread* handles differently the way forums & topics are set as read.

*  For **topics**, a post meta *bbppu_read_by* is attached to the topic each time a someone visits it; the meta value is the user ID.  When a new reply is added, all those metas are deleted.

*  For **forums**, we compare the total count of topics with the total count of read topics for the current user.  If it does not match, the forum is considered as unread.

*  Marking a forum (*Mark all as read*) adds an entry with the forum ID and timestamp in *bbppu_marked_forums* (usermeta).  When determining if a topic has been read, we check if the topic's forum (or ancestors) has a mark more recent than the topic time.

* Marking a forum will only set the topics from this forum as read.  If there is **super sticky topics** displayed and that they belong to other forums, they will not be marked as read.

= How can I use those functions outside of the plugin ? =

Have a look at the file /bbppu-template.php, which contains functions you could need.

= How can I see the plugin's log ? =

The plugin will generate various notices and informations in the debug.log file, if [debugging is enabled](https://codex.wordpress.org/Debugging_in_WordPress).

== Screenshots ==

1. Style of the read / non-read forums.  The flag icon is a link to reach the last read reply.
2. Options page

== Localization ==

If it hasn't been done already, you can translate the plugin and send me the translation.  I recommand [Loco Translate](https://fr.wordpress.org/plugins/loco-translate/) to work on your translations within Wordpress.

== Changelog ==

= 1.3.0 =
* Try to optimize queries that count forum topics in has_user_read_all_forum_topics():
* 'no_found_rows' => true (see https://wpartisan.me/tutorials/wordpress-database-queries-speed-sql_calc_found_rows); so use count() instead of found->posts

= 1.2.9 =
* when comparing the topics read, only fetch IDs instead of full post
