图像URL出现在WordPress短代码输出中的错误位置

Question

I'm trying to make a shortcode for displaying logged in user avatar from buddypress

// user avtar
function user_avatar() {
    $user_avatar_url = bp_loggedin_user_avatar('type=full&html=false'); 
    $user_image = '<img src="' . $user_avatar_url  . '"/>';
    return $user_image;
}
add_shortcode('avatar', 'user_avatar');

but when I try to insert shortcode [avatar], the HTML output looks like this:

http://localhost/.../images/bp_default_avatar.jpg <img src=""></img>

Somehow image url/src appears before 'img' tag?

Answer 1

Apparently it was the buddypress issue, I changed a few things and now it's working

// user avtar
function user_avatar() {
$userid = bp_loggedin_user_id();
$user_avatar_url = $avatarurl = bp_core_fetch_avatar( array( 'item_id' => $userid, 'html' => false ) ); 
$user_image = '<img src="' . $user_avatar_url  . '"/>';
return $user_image;

}
add_shortcode('avatar', 'user_avatar');
