Why doesn't this code to display avatars work?

[tomotron]

I'm trying to display avatars (hosted in the filesystem) on a non-vb page. Basically, I'm supplying a userid and want to display the avatar...

PHP Code:


$avatarid = 1;

require_once('./includes/functions_user.php');

$avatarurl = fetch_avatar_url($avatarid);
        if ($avatarurl[0])
        {
            $avatarurl = $avatarurl[0];
        }
        else 
        {
            $avatarurl = "noavatar.gif";
    } 


$avatarurl never contains any data

From all the examples I've read it seems like this *should* work, am I making a stupid mistake? Any help is appreciated!

--------------- Added [DATE]1239745335[/DATE] at [TIME]1239745335[/TIME] ---------------

also, just to be clear this file resides in my vbulletin directory so the path to functions_user.php should be good.

anybody? is there another solution to display avatars that are NOT hosted in the database on a non vb page?

Exactly what is getting displayed in the source code? And maybe it would be better to go:

PHP Code:

       if (!empty($avatarurl)) 
        { 
            $avatarurl = $avatarurl; 
        } 
        else  
        { 
            $avatarurl = "noavatar.gif"; 
    }

^^ I think we're basically doing the same thing there?

When i try to run this and print the results using "echo $avatarurl;" for example I get nothing. It doesn't display noavatar.gif which should display if $avatarurl is empty.

I can replace,

$avatarurl = fetch_avatar_url($avatarid);
with
$avatarurl = 1;

and the script runs and I can display the results (which are 1), so my issue lies with the fetch_avatar_url($avatarid); portion which doesn't seem to be pulling the info it's supposed to.
Do I need to include other files to access that function?

Did you look at the API for that function? I believe it returns an array. Is $avatarurl defined as an array? According to the API, that is the correct file to include.

[tomotron]

Yeah looking at the API is where I got most of this code.

The if statement should deal with the array,

basically saying if there is a value for $avatarurl[0] assign it to $avatarurl, otherwise gave $avatarurl the value "noavatar.gif"

Try a

print_r($avatarurl);

[tomotron]

^^ Tried it, I think $avatarurl = fetch_avatar_url($avatarid); just isn't working

[Lynne]

Did you try looking in the vb code to find a some code where this function is and then just copying it?

And, if $avatarurl is defined as an array, you can't then just go use it as if it isn't an array.

I'm not so sure I think the problem is in my code, but more than I'm trying to do this on a non-vb page and there's a step I'm missing to be able to use that function.

$avatarurl is an array, but I am using it as one... $avatarurl[0] would access the first element in the array which should be the URL for the avatar.
