Delete your call to
bp_core_load_template( apply_filters( 'bp_core_template_plugin','members/single/swap' ) );

Use this call

function my_groups_page_function_to_show_screen_content() {
	bp_get_template_part('members/single/swap');
}

Add these functions:

function luisa_register_template_location() {
    return 'path to your templates' . '/templates/';
}

function luisa_template_start() {

    if( function_exists( 'bp_register_template_stack' ) )
        bp_register_template_stack( 'luisa_register_template_location' );

}
add_action( 'bp_init', 'luisa_template_start' );

Hi @luisa227,

considering your questions, i would suggest you read attentively both WP and BP codex.

– child theme
– bp-custom

bp-custom.php goes to wp-content/plugins/ directory, not into the (child)theme folder.

such path members/single/swap is related to BP legacy by default.

But as swap is a custom folder, that custom path means in fact wp-content/themes/child-theme/buddypress/members/single/swap.php, where /child-theme/buddypress/contains copies of all your customized legacy files and your own additionnal files you want to use.

Hopefully reading the codex will help you to understand a little better how all this works together.

Read here:

Template Overload from a Plugin

Here a working example you can study to understand (and use to see how it works)

function bpfr_post_profile_setup_nav() {
global $bp;

	$parent_slug = 'audio';
	$child_slug = 'posts_sub';	
	$post_count = count_user_posts(  bp_displayed_user_id(), array('post', 'post' ) );

		//Add nav item with posts count
		bp_core_new_nav_item( array(
			'name' => __( 'Audios' ) .'<span>'.$post_count.'</span>',
			'slug' => $parent_slug,
			'screen_function' => 'bpfr_profile_post_screen',
			'position' => 40,
			'default_subnav_slug' => $child_slug 
		) );
		
		//Add subnav item 	 
		bp_core_new_subnav_item( array( 
			'name' => __( 'My latest audios' ),
			'slug' => $child_slug, 
			'parent_url' => $bp->loggedin_user->domain . $parent_slug.'/', 
			'parent_slug' => $parent_slug, 
			'screen_function' => 'bpfr_profile_post_screen'
		) );

	}

	function bpfr_profile_post_screen() {	
		add_action( 'bp_template_content', 'bpfr_profile_post_screen_content' );
		bp_core_load_template( apply_filters( 'bp_core_template_plugin', 'members/single/plugins' ) );
	}

	function bpfr_profile_post_screen_content() {
		do_action( 'my_profile_post' );
	}

add_action( 'bp_setup_nav', 'bpfr_post_profile_setup_nav' );

And here a content test:

function luisa_conteni() {
   echo 'Forza BuddyPress';
}
add_action( 'my_profile_post', 'luisa_conteni' );

Add all snippets to bp-custom.php.

The example use the default plugin template (/members/single/plugin.php) as generally there is no need to create a new template while on a profile (except if you need something very specific like a table or a an iframe).

Now, it’s me who doesn’t understand ! What do you want to do finally ? What is not working for you ?

Or try to get some help on the italian WP forum.

Support Forums

or get in touch with one of BP’s italian translator for help or at least some explanation
Italian BP translators list

Forgot custom profile menu plugin and use custom code, as it is much simplier.

Here another example, with Swap at the first position on the buddybar on profiles.

function bpfr_swap_luisa_nav() {
global $bp;

	$parent_slug = 'swap';
	$child_slug = 'swap_sub';		

		//Add nav item 
		bp_core_new_nav_item( array(
			'name' => __( 'Swap' ),
			'slug' => $parent_slug,
			'screen_function' => 'bpfr_profile_swap_screen',
			'position' => 10, // 10 is the first position on buddybar
			'default_subnav_slug' => $child_slug 
		) );
		
		//Add subnav item 	 
		bp_core_new_subnav_item( array( 
			'name' => __( 'My Swaps' ),
			'slug' => $child_slug, 
			'parent_url' => $bp->loggedin_user->domain . $parent_slug.'/', 
			'parent_slug' => $parent_slug, 
			'screen_function' => 'bpfr_profile_swap_screen'
		) );

	}

	function bpfr_profile_swap_screen() {	
		add_action( 'bp_template_content', 'bpfr_profile_swap_screen_content' );
		bp_core_load_template( apply_filters( 'bp_core_template_plugin', 'members/single/plugins' ) );
	}

	function bpfr_profile_swap_screen_content() {
		do_action( 'my_profile_swap' );
	}

add_action( 'bp_setup_nav', 'bpfr_swap_luisa_nav' );

The following function introduce the content related to Swap. As i ignore how that plugin works, i can’t give you a working example for it. It would be nice to indicate the exact plugin name and upload url. Also is it compatible with BP ?

function bpex_swap_stuff() {
?>
<h2>Lorem Ipsum for ever !</h2>
<p>Aenean suscipit nulla in justo. Suspendisse cursus rutrum augue. Nulla tincidunt tincidunt mi. Curabitur iaculis, lorem vel rhoncus faucibus, felis magna fermentum augue, et ultricies lacus lorem varius purus. Curabitur eu amet.</p>
<?php
}
add_action( 'my_profile_swap', 'bpex_swap_stuff' );
