Hello, I have also been trying to get a new topic button working for some time. In case it is of help to anyone, this is what seems to work for me.

I created a wordpress page template “forum.php” and added the following code – it adds a ‘New Question’ button to the forum page but not if it’s the parent forum:

<?php
get_header(); 

while ( have_posts() ) : the_post();
if((($post_type = get_post_type()) == 'forum') ) //make sure we are on a forum
{
  if(bbp_get_forum_id() != 0) //don't add the button to the parent forum
  {
    ?>
    <a href="<?php echo esc_url( add_query_arg( 'c', bbp_get_forum_id( ), site_url( '/new-topic/' ) ) )?>">New Question</a>
    <?php
  }
}
the_content();
endwhile; // End of the loop.    
?>
<?php get_footer();

Now when I click the New Question link it opens the page new-topic and the forum I was on when I pressed the button is the forum the new question will be placed in.

new-topic is a page I created in wordpress, and I gave it a template page-new-topic.php

It contains the following code:

<?php
get_header(); 
$my_c = get_query_var( 'c' );
$forum_add_topic='[bbp-topic-form forum_id='.$my_c.']';
echo do_shortcode($forum_add_topic);
?>
<?php get_footer();

The line

<a href="<?php echo esc_url( add_query_arg( 'c', bbp_get_forum_id( ), site_url( '/new-topic/' ) ) )?>">New Question</a>

in forum.php adds a variable c (which contains the current forum id() -bbp_get_forum_id( ) ) to the url when New Question is clicked.

In page-new-topic.php this variable c is added to the shortcode [bbp-topic-form forum_id=XXX]

do_shortcode then runs the shortcode which creates the form.

I also had to add the following to functions.php to tie the two pages together:

function add_custom_query_var( $vars ){
  $vars[] = "c";
  return $vars;
}
add_filter( 'query_vars', 'add_custom_query_var' );

You could add this as a plugin if you wish.

The idea for the shortcode came from this post: post

How to pass variables through wordpress urls came from this post:

I am new to WordPress and PHP so there may be better ways of doing this but, as I said, this seems to work.
