Hi, guys!

I have a problem with topic filters – i need to filter my topics by custom meta value (date from custom field) in this website http://sopernik.sites.in.ua/ . I have events, what realised like topics, client want to filter these event by date what you can take in custom field.

Could you help me with it?

untested by this should work

//change topic order
add_filter('bbp_before_has_topics_parse_args', 'rew_topic_order_by_meta');

function rew_topic_order_by_meta ($args) {
	$args['meta_key'] = 'put_meta_key_here' ;
	$args['orderby']    = 'meta_value' ;
	$args['order']     = 'DESC' ;  //or ASC if needed
	return $args ;
}

just put your meta_key where it says

I found this also:

function my_custom_display_topic_index_query () {
$args[‘orderby’] = ‘date’;
$args[‘order’] = ‘DESC’;

return $args;
}
add_filter(‘bbp_before_has_topics_parse_args’, ‘my_custom_display_topic_index_query’ );

You wrote that buttons for that would be complicated, but if I reload the page and use GET-parameters, this way, would this work:

function my_custom_display_topic_index_query () {
if($_GET[…]==…) $myOrder=’date’; elseif(…) //or switch – then used a select box)
if ($_GET[‘descAsc’]==…) $descAsc=’DESC’;
$args[‘orderby’] = $myOrder;
$args[‘order’] = $descAsc;

return $args;
}
add_filter(‘bbp_before_has_topics_parse_args’, ‘my_custom_display_topic_index_query’ );

Buttons or select box would be inside the template and it gets the current webaddress and add desired parameters. If I add also cookies, the change would not need to do every time.

Exactly I think this code:

function my_custom_display_topic_index_query () {
global $_GET;
if($_GET[‘myOrderBy’])$myOrderBy=$_GET[‘myOrderBy’];else $myOrderBy=’last_edited’;
if($_GET[‘myOrder’])$myOrder=$_GET[‘myOrder’];else $myOrder=’DESC’;
$args[‘orderby’] = $myOrderBy;
$args[‘order’] = $myOrder;

return $args;
}
add_filter(‘bbp_before_has_topics_parse_args’, ‘my_custom_display_topic_index_query’ );

function printSelections(){
global $_SERVER;
return ‘<div class=”queries”><form action=”https://&#8217; . $_SERVER[‘HTTP_HOST’] . $_SERVER[‘REQUEST_URI’].'”><table class=”querytable”><tr><td><select name=”myOrderBy”><option value=”post_modified”>Viimeisin muutos</option><option value=”post_date”>Luontipäivä</option><option value=”post_title”>Nimi/option><option value=”post_author”>Tekijä/option></select></td><td><input name=”myOrder” type=”radio” value=”DESC” />Laskeva</td><td><input name=”myOrder” type=”radio” value=”ASC” />Nouseva</td></tr></table></form>’;
}

add_shortcode( ‘printSelections’, ‘printSelections’ );
// Add do_shortcode(‘printSelections’); to loop-forums.php
<li class=”bbp-header”>

<ul class=”forum-titles”>
<li class=”bbp-forum-info”><?php _e( ‘Forum’, ‘bbpress’ ); ?><?php topPostLinksEcho(); ?>
<li class=”bbp-forum-topic-count”><?php _e( ‘Topics’, ‘bbpress’ ); ?>
<li class=”bbp-forum-reply-count”><?php bbp_show_lead_topic() ? _e( ‘Replies’, ‘bbpress’ ) : _e( ‘Posts’, ‘bbpress’ ); ?>
<li class=”bbp-forum-freshness”><?php _e( ‘Freshness’, ‘bbpress’ ); ?>

<?php do_shortcode(‘[printSelections]’); ?>

depends on how you define complicated – solutions are frequently only a few lines of code, but getting there takes the time 🙂
