Reply To: Custom Breadcrumbs (what URL to use for forum)

I’d suggest you do this as follows:

there is a ‘hook’ that you show above called ‘<?php do_action( ‘bbp_template_before_single_topic’ ); ?>’

This tells bbpress to do any action that is added at that point.

so adding a hook will mean that the function is called at that point.

The following code should go in your child theme functions file, or use the code snippets plugin

Code Snippets

add_action ( 'bbp_template_before_single_topic' , 'rew_back' ); 

function rew_back () {
	$text = 'click to go back' ;
	if (bbp_get_topic_forum_id() == '25') $href = home_url( '/forum/domestics/' ) ;
	if (bbp_get_topic_forum_id() == '33') $href = home_url( '/forum/commercial/' ) ;
		//where to go if page not there
	else $href = home_url( '/login/' ) ;
	echo '<a class="button" href ="'.$href.'">'.$text.'</a>' ;
}

so each forum will need a line.
