I tried another method but no way bbp_forum_id only displays the forum id.I tried with I tried with “bbp_get_forum_id” that doesn’t work either.
<div id="bbpress-forums" class="bbpress-wrapper">
<?php bbp_breadcrumb(); ?>
<?php //bbp_forum_subscription_link(); ?>
<?php do_action( 'bbp_template_before_single_forum' ); ?>
<?php if ( post_password_required() ) : ?>
<?php bbp_get_template_part( 'form', 'protected' ); ?>
<?php else : ?>
<?php //bbp_single_forum_description(); ?>
<?php if ( bbp_has_forums() ) : ?>
<?php bbp_get_template_part( 'loop', 'forums' ); ?>
<?php endif; ?>
<?php if ( ! bbp_is_forum_category() && bbp_has_topics() ) : ?>
<?php bbp_get_template_part( 'pagination', 'topics' ); ?>
<?php bbp_get_template_part( 'loop', 'topics' ); ?>
<?php bbp_get_template_part( 'pagination', 'topics' ); ?>
<?php bbp_get_template_part( 'form', 'topic' ); ?>
<?php elseif ( ! bbp_is_forum_category() ) : ?>
<?php if(bbp_forum_id() === '513'): ?>
<?php echo 'yes'; ?>
<?php else : ?>
<?php bbp_get_template_part( 'feedback', 'no-topics' ); ?>
<?php bbp_get_template_part( 'form', 'topic' ); ?>
<?php ?>
<?php endif; ?>
<?php endif; ?>
<?php endif; ?>
<?php do_action( 'bbp_template_after_single_forum' ); ?>
</div>
