BuddyPress.org

Hi,
I just start to create a web site with buddypress, so I dont understand so much things.
Since 3 days I search for a solution please help me …
I just try to display differents custom field (that I create with BUDDYFORM ACF for my form post )
When I try to display with get_field (‘image_livre’) that work only in single.php ( theme understrap) but not in entry.php ( buddypress).
I think its with this code that i can do something.. but i dont understand where and how wrote that.
I have 3 custom = #image_livre #titre_livre #description_livre

add_filter( 'buddyblog_post_form_settings', 'buddydev_custom_buddyblog_settings' );

function buddydev_custom_buddyblog_settings( $settings ) {

	$custom_fields = $settings['custom_fields'];

	$custom_fields['image_livre'] = array(
		'type'		=> 'image',
		'label'		=> 'image du livre',
		'default'	=> ""
	);

i hope someone can help me

thank you
