(WPML + BBPress) Recent topics widget not translatable

[diegootgs]

Hi there, this is Diego from the WPML Compatibility team.

I would like to report a new issue with BBPress.

Steps to Reproduce

• Setup WP with two languages and BBPress
• Create a forum, a topic and translate them
• Place the "Recent topics" widget inside the footer and try to translate it
• Note that the recent topics widgets are not displayed in second language.

Debug
For building the widgets, BBPress is using 'post_parent' => $settingsparent_forum?, in its WP_Query query. As values, receives 'any' or an array of numerical ID's (post ID's).

However, checking the WP_Query handbook: post_parent (int) – use page id to return only child pages. Set to 0 to return only top-level entries.

I don't see the possibility of using a string or 'any' and WPML can't recognises it. It seems like something intended by the author. For example, you can see that they forces this value in other instances:

// Force to any
                if ( ! empty( $instance['parent_forum'] ) && ! is_numeric( $instance['parent_forum'] ) ) {
                        $instance['parent_forum'] = 'any';
                }

Workaround

Option 1:

• Edit the widget.
• Look for the "Parent Forum ID" field and leave it empty instead of using 'any'.

Option 2:
Open .../wp-content/plugins/bbpress/includes/common/widgets.php fie.

Look for line 678:

$settings = $this->parse_settings( $instance );

Just after, add this code:

//workaround compsupp-7407
		if ( class_exists('Sitepress')  && $settings['parent_forum'] ===  'any' )  {
			$settings['parent_forum'] = '';
		}
