So on that logic, as I am 111,301 I can presumably expect a truckload of abuse.

Lol ;-)
Well, there's 100,000 before you and 300,000 after. You can create a new account and be in a worse predicament if you'd like :P

Thanks, gerdami!

Shane!!!! I got it!

Have a look at this:

[[image http://wdpkg.ejohnson.info/getavatar.php?u=pieterh]]

[[image http://wdpkg.ejohnson.info/getavatar.php?u=tsangk]]

[[image http://wdpkg.ejohnson.info/getavatar.php?u=leiger]]

[[image http://wdpkg.ejohnson.info/getavatar.php?u=leiger&size=48]]

Wow, I'm impressed. Thanks a lot! :)

Is there any way for me to do this without reliance on Ed's http://wdpkg.ejohnson.info website?

And any idea on what sizes are available? Is it just that small size, plus the 48px one, or are there other sizes?

You can do this be changing the size of the image!

[[image http://wdpkg.ejohnson.info/getavatar.php?u=leiger&size=48 width="20"]]

And it's a PHP script. You can host it on your own website - but not on Wikidot!

<?php
$size=$_GET["size"];
if(empty($size))
{
$size="16";
}
$username=$_GET["u"];
$page=file_get_contents("http://www.wikidot.com/search:users/q/".$username);
preg_match('/avatars\/([0-9]{1,4})\/([0-9]{1,11})\/a16.png/s',$page,$matches);
$img=file_get_contents("http://www.wikidot.com/common--images/avatars/".$matches[1]."/".$matches[2]."/a".$size.".png");
echo $img;
?>

I don't have any separate websites, so I suppose I'll have to rely on this method then. Did you write the PHP script just then, yourself?

tsangk — you're a legend! :) Because I can use the user's name instead of their ID, I can use this on other pages as well! =)

Yeah. I know PHP. And I just started writing the script since I posted about not being able to get in any other way :-)

Okay, for some reason this isn't working for all users. You may have some idea why, hopefully…

Only my two avatars are working, above :S

To prove that these are all valid usernames:

• leiger
• ProtoKun7
• MrMicx

Done. Updated it :-)

And I found another problem xD

I've used the %%created_at%% variable for the name, but anything with a space in it doesn't work.

Bob Bobson
James Kanjo

[[image http://wdpkg.ejohnson.info/getavatar.php?u=Bob Bobson]]
[[image http://wdpkg.ejohnson.info/getavatar.php?u=James Kanjo]]

Replacing the spaces with %20 doesn't seem to work either. Is this a limitation of the %%created_by%% variable? I recall that there are problems with the page manager pieterh created for people with spaces in their name.

How about a script that just works by User ID ? All you'd have to do in the script is work out how many thousands there are, and bingo, you've got everything that is needed to figure out the profile image URL.

Good job,

The problem with the spaces occurs within Wikidot. [[image url[space]attributes]]

And - yes. I can make one that works with user id as well - do you need it?

if you do it manually of course… inside a Listpages … I don't know

It's not inside a ListPages module, but inside a live template. Minor technicality, as the variables act the same either way…

@tsangk: If you created one that accepted the user ID, I wouldn't need to worry about usernames with spaces. That advantage alone would be enough to make me want to use it :)

Shane,

Don't worry about bandwidth or my web space going away anytime soon. Forever is a long time, but I do intend to keep my space until my heirs decide to cancel the account some day. ;)

I can't imagine that a relatively quick hit to that script would suck up enough bandwidth to be an issue at all.

Can you do custom sizes? If not, what is the biggest size you can do with these images?

[[image http://wdpkg.ejohnson.info/getavatar.php?u=graphmastur&size=48 width="64"]] This is awesome!

There are only two default sizes. They are 16 and 48.

48 renders 100px x 100px
16 renders 16px by 16px

I also made a package for this. See it here: http://csi.wikidot.com/package:20/noredirect/true

No error messages … just that the anonymous avatar is shown instead.

Shane, bug fixed :-)
EDIT: Ed, bug fixed for you too!

Thanks! Can you explain what the bug was? I know what the bug was actually… can you explain what the cause of the bug was? :P

Hmmmm….. The cause of the bug…….
The original code grabbed the avatar url from the user search page:

<?php
$size=$_GET["size"];
if(empty($size))
{
$size="16";
}
$username=$_GET["u"];
$page=file_get_contents("http://www.wikidot.com/search:users/q/".$username);
preg_match('/avatars\/([0-9]{1,4})\/([0-9]{1,11})\/a16.png/s',$page,$matches);
$img=file_get_contents("http://www.wikidot.com/common--images/avatars/".$matches[1]."/".$matches[2]."/a".$size.".png");
echo $img;
?>

The search page for some strange reason displayed the less relevant searches first…..
e.g. http://www.wikidot.com/search:users/q/Fingerz displays:

1. Fingerzam <- Script took this user's avatar……
2. quickfingerz
3. Fingerz5217
4. flexyfingerz
5. fingerz <- the avatar we really want…….

My script goes for the first one displayed in the page so the solution:

Grab from user info page - e.g. http://www.wikidot.com/user:info/fingerz

I also had to lower the case of the string to comply with the strict case lettering of the UNIX systems :-)

Aha, thanks :) That makes sense.

I always wondered why usernames had to be lowercase when accessing the profile pages. From what you told me, it's a restriction of the UNIX servers that Wikidot is using? At least your script lowers the case automatically.

it's a restriction of the UNIX servers that Wikidot is using?

UNIX treats case strictly. For example UNIX would see MyImage.jpg and myimage.jpg as two different files. If you were to download those files to the same folder on your Windows PC, you would get prompted to overwrite the first file with the second.

Wikidot has fields (among others) in the user table called "nick_name" and "unix_name". nick_name stores the displayed name we see and the unix_name is a "lower case/hyphens replace spaces" version of our nick_name. Links created by [[user User Name]] are created using the UNIX name (/user:info/user-name). Since the unix_name is always stored as a lower case version of the nick_name, it's simple to parse any name entered in [[user UsEr NamE]]. You just force it to lower case and add the hyphens. Using the unix_name is probably easiest and makes the most sense from a programming standpoint. Especially the way spaces in user names wreak havoc around here. ;)

Okay, tsangk… now you've broken the avatars for anonymous users! ;-) I expect this is because there is no user at http://www.wikidot.com/user:info/anonymous

Previously, it showed the default image for anonymous users (the smiley face)… and now it shows this:

[[image http://wdpkg.ejohnson.info/getavatar.php?u=anonymous&size=48]]

Perhaps you could make an exception for just Anonymous users, to not look for the image on the user:info page?

Bug should be fixed. Added exception to string "anonymous" (case non-sensitive) in the variable $username.

Thanks
