How can i overwrite bbpress functions? I want to pass custom arguments in:
function bbp_get_topic_admin_links()
function bbp_get_reply_admin_links()
and
function bbp_list_forums();

example:
i want to remove the seperator form bbp_list_forums: ‘separator’ => ‘, ‘
now i modified the corresponding template.php files. but i think its better to find the righ hooks to pass custom arguments to those functions?!

thanks!

Functions in bbpress are held in the template-tag files

so for instance
bbp_reply_admin_links is held in bbpress/includes/replies/template-tags.php

bbp_topic_admin_links is held in bbpress/includes/topics/template-tags.php

bbp_list_forums is held in bbpress/includes/forums/template-tags.php

open these up and you’ll see what argumens they use, and how to filter – from your post I am presuming you know how to create filters.

[@nicmare Participant 10 years, 10 months ago]

Yes. So this is my code which works:

add_filter('bbp_list_forums','custom_bbp_list_forums',10);
function custom_bbp_list_forums( $args = '' ) {

	// Define used variables
	$output = $sub_forums = $topic_count = $reply_count = $counts = '';
	$i = 0;
	$count = array();

	// Parse arguments against default values
	$r = bbp_parse_args( $args, array(
		'before'            => '<ul class="bbp-forums-list">',
		'after'             => '</ul>',
		'link_before'       => '',
		'link_after'        => '',
		'count_before'      => '<span>',
		'count_after'       => '</span>',
		'count_sep'         => '</span><span>',
		'separator'         => '',
		'forum_id'          => '',
		'show_topic_count'  => true,
		'show_reply_count'  => true,
	), 'list_forums' );

	// Loop through forums and create a list
	$sub_forums = bbp_forum_get_subforums( $r['forum_id'] );
	if ( !empty( $sub_forums ) ) {

		// Total count (for separator)
		$total_subs = count( $sub_forums );
		foreach ( $sub_forums as $sub_forum ) {
			$i++; // Separator count

			// Get forum details
			$count     = array();
			$show_sep  = $total_subs > $i ? $r['separator'] : '';
			$permalink = bbp_get_forum_permalink( $sub_forum->ID );
			$title     = bbp_get_forum_title( $sub_forum->ID );

			// Show topic count
			if ( !empty( $r['show_topic_count'] ) && !bbp_is_forum_category( $sub_forum->ID ) ) {
				$count['topic'] = bbp_get_forum_topic_count( $sub_forum->ID );
			}

			// Show reply count
			if ( !empty( $r['show_reply_count'] ) && !bbp_is_forum_category( $sub_forum->ID ) ) {
				$count['reply'] = bbp_get_forum_reply_count( $sub_forum->ID );
			}

			// Counts to show
			if ( !empty( $count ) ) {
				$counts = $r['count_before'] . implode( $r['count_sep'], $count ) . $r['count_after'];
			}
		}
		// Output the list
		echo apply_filters( 'bbp_list_forumss', $r['before'] . $output . $r['after'], $r );
	}
}

but maybe there is an easier way to modify arguments array?!

[@robin-w Moderator 10 years, 10 months ago]

Most bbp functions have simple variables. Yes, there must be a shorter way, but this is an array not a simple variable, and it builds an unordered list using the array and a loop.

It has an “apply filters” as part of the function, so they are expecting it to be able to be filtered, but hopefully not by having to do it all again !

I am writing some codex guide for filtering in bbPress, and by co0incidence was just using this oen as an example, and have been trying to crack it.

I can do it by amending the template –

https://codex.bbpress.org/layout-and-functionality-examples-you-can-use/ section 2, and save template into

wp-content/themes/yourthemename/bbpress

bbPress then uses that one.

I have posted a fresh query to Stephen Edgar or JJJ to pick up, but it’s gone into moderation as I posted a whole lot of code. Hopefully one of the two will pick it up and answer.

In the meantime yours is so far the best answer !

[@robin-w Moderator 10 years, 10 months ago]

Ok, I’ve had a think, and another look.

There is no easy way to do less than you’ve done.

The problem is that by the time the “apply filters” has been applied, the $output variable has already been created using the input variables, so changing $r is too late.

What this function needs is an earlier apply filters called say ‘bbp_list_forums_args’ for the $r variable, the you could add a simple filter along the lines of

function hide_forum_counts ($r) {
$r['show_topic_count'] = false ;
$r['show_reply_count'] = false ;
$r['separator']  = ' ';
return $r ;
}
add_filter('bbp_list_forums_args','hide_forum_counts') ;

I’ve have suggested this is a trac ticket

[@nicmare Participant 10 years, 10 months ago]

yea. such a solution would be awesome and keeps updates of bbpress more save!
because the separator value was annoying to me, i had to create such a big function just to overwrite this simple argument.

[@robin-w Moderator 10 years, 10 months ago]

I’ll let you know if it gets changed.

Were the other two functions as bad?

[@netweb Keymaster 10 years, 10 months ago]

@nicmare To remove the separator:

add_filter('bbp_before_list_forums_parse_args', 'nicmare_bbpress_list_forums' );
function nicmare_bbpress_list_forums() {
	$args['separator']        = '';
	return $args;
}

A good explanation for bbp_get_topic_admin_links and bbp_get_reply_admin_links is here:

Could a plugin developer protect his functions?

[@robin-w Moderator 10 years, 10 months ago]

@netweb Stephen, Thanks for this, and having now looked at the trac ticket and bbp_parse_args function I see how this works.

@nicmare

Wherever you see bbp_parse_args, there’s a filter for the function to do this.

bbp_parse_args has the format

function bbp_parse_args( $args, $defaults = array(), $filter_key = '' )

The resultant filter name is made up of bbp_before_’ . $filter_key . ‘_parse_args’

(there is an bbp_after one as well!)

The filter key is the third argument in the bbp_parse_args

$r = bbp_parse_args( $args, array(
		'before'            => '<ul class="bbp-forums-list">',
		'after'             => '</ul>',
		'link_before'       => '',
		'link_after'        => '',
		'count_before'      => '<span>',
		'count_after'       => '</span>',
		'count_sep'         => '</span><span>',
		'separator'         => '',
		'forum_id'          => '',
		'show_topic_count'  => true,
		'show_reply_count'  => true,
	), 'list_forums' );

so ‘list_fourms’ in the last line is the third argument.

This should help you for the other two functions, as filters will then be obvious !

yea. finally! thank you guys for making that clear.
