how can I show Idea's title on members list bbp

Hi, if i understand well: you are looking for a way to display the latest idea a member posted inside the BuddyPress members loop.

here’s how you could do :

function natty_latest_idea_in_members_directory() {
	// Ideally, there should be a cache strategy to improve performance.
	$idea = wp_idea_stream_ideas_get_ideas( array(
		'author'   => bp_get_member_user_id(),
		'per_page' => 1,
	) );

	if ( empty( $idea['ideas'] ) ) {
		return;
	}

	$latest_idea = reset( $idea['ideas'] );

	if ( ! is_a( $latest_idea, 'WP_Post' ) ) {
		return;
	}

	// always use this function to build the idea permalink!
	$latest_idea_link = wp_idea_stream_ideas_get_idea_permalink( $latest_idea );
	?>
	<p>Latest idea: <a href="<?php echo esc_url( $latest_idea_link );?>" title="<?php echo esc_attr( $latest_idea->post_title );?>"><?php echo esc_html( $latest_idea->post_title );?></a></p>
	<?php
}
add_action( 'bp_directory_members_item', 'natty_latest_idea_in_members_directory' );

You must know this will bring you some overload in the display of the members directory. There should be a cache strategy to avoid to request for posts at each member. So i think, i wouldn’t advise you to use this as is, but i would advise you to ask a WordPress/BuddyPress developer to build the feature so that it doesn’t overload too much the loading of this specific page.

great I will try it asap! and I will try to learn about caching… nice plugin indeed!

I’ve one more question for you, and I don’t know if is better to open a new post.
Anyway:

I’ve a problem with the list of all ideas from all user, the page template broke my header from my theme, but is supported from the other pages ( new idea, my-ideas).
So I put on my theme’s folder like you suggest here
https://github.com/imath/wp-idea-stream/wiki/Ways-to-customize-the-plugin-from-your-theme
the structure of folders:
/wp-idea-stream/templates
and then I’ve tried to edit the archive.php page, but nothin happen, it seems that the template isn’t used!
where I wrong? or I’ve to edit some other page or parts?

thanks again
