Flashchat - who is online with showing the chatters avatars

this is a beta release of a "who is online" mod for Flashchat

Version 0.2

What's new:

• now working with prefixes for the database tables
• now working with gif-avatars too
• resize option (yes / no)
• better image quality because of gdlib2

Features:

• generate dynamically resized avatar-pics for the chatting users
  and displays them on the forumhome with the username and a link to their profile

issues/bugs/ todo:

• if too many users are chatting, the tablerow grows and grows instead of breaking into a new tablerow (fixing it later)
• doesn't show avatars when they aren't stored in the db(thekeeper)

note: you need the gdlib2

installation and upgrade information inside the .zip

@quasan, thank you very much for your support, it works now! Even though it only works with .jpg - all the .gif show the noavatar.gif.

Is that supposed to be like that or have i got something wrong?

[FilmoreSlim]

the new version of GD doesn't support the "gif" (the format is licensed or something) format. GD doesn't recognize .gif, unless you are running an older version of GD :\

[quasan]

FilmoreSlim that may be right but even in gdlib2 there are functions to transform gif, etc..
I will add this function to my to do list and have closer look on it

[FilmoreSlim]

Oh really? Hmm, I need to check that out then! Oh and thanks for supporting this hack quasan

[quasan]

ok using gif pics works now, i hope I get a new version online asap

@FilmoreSlim just use the imagecreatefromgif function for working with gifs

@quasan: did you exchange the .zip already with a version that works with .gif? (dont mean to push you, just wasnt sure what you meant)

@The Keeper: when i use the code you provided in your hack i get the following error:

Fatal error: Cannot redeclare fetch_avatar_url() in ......................./forum/includes/functions_user.php on line 116

Do you know how to fix that?

[quasan]

Yeah sorry I put the function in teh wrong place (inside a loop, what an idiot ) Hang on a sec...

// ### HACK FOR WHO'S CHATTING

$query_chatonline ="SELECT COUNT(*) FROM connections WHERE userid IS NOT NULL";
$count = mysql_fetch_array(mysql_query($query_chatonline));
$count_chatter = $count[0];





// ###################### Start getavatarurl #######################
function fetch_avatar_url($userid)
{
	global $DB_site, $session, $vboptions;

	if ($avatarinfo = $DB_site->query_first("
		SELECT user.avatarid, user.avatarrevision, avatarpath, NOT ISNULL(avatardata) AS hascustom, customavatar.dateline
		FROM " . TABLE_PREFIX . "user AS user
		LEFT JOIN " . TABLE_PREFIX . "avatar AS avatar ON avatar.avatarid = user.avatarid
		LEFT JOIN " . TABLE_PREFIX . "customavatar AS customavatar ON customavatar.userid = user.userid
		WHERE user.userid = $userid"))
	{
		if (!empty($avatarinfo['avatarpath']))
		{
			return $avatarinfo['avatarpath'];
		}
		else if ($avatarinfo['hascustom'])
		{
			if ($vboptions['usefileavatar'])
			{
				return "$vboptions[avatarurl]/avatar{$userid}_{$avatarinfo[avatarrevision]}.gif";
			}
			else
			{
				return "image.php?u=$userid&dateline=$avatarinfo[dateline]";
			}
		}
		else
		{
			return '';
		}
	}
}



//if anyone is chatting.....
if($count_chatter >0)
{
 
	//get the uids of the chatters
	$query_userid = "SELECT userid FROM connections WHERE userid IS NOT NULL";
	$show_userid = mysql_query($query_userid);
	$row_show_userid = mysql_fetch_assoc($show_userid);
	
	//build an array of the userids
	do {	
	$userids[] = $row_show_userid['userid'];	
	} while ($row_show_userid = mysql_fetch_assoc($show_userid));
	

// Get the usernames and build the outputVar for the template
foreach($userids as $val)
{

	//Get the username for each chatter
	$show_username= $DB_site->query("select username from user where userid=".intval($val));
	$row_show_username = mysql_fetch_assoc($show_username);


	//pass the userid to the avatar_resize.php
	$chatavatar = fetch_avatar_url($val);


	// store the htmloutput for each user in $temp 
	$temp = "<td><tr>";
	$temp.= "<img src=\"$chatavatar\">";
	$temp.= "<div align=\"center\">";
	$temp.= "<a href=\"member.php?u=".$val."\">".$row_show_username['username']."</a>";
	$temp.= "</div>";
	$temp.= "</tr><td>";
	$temp.= "<br />";
	

	// concatenate the temp stuff to > $chatusers
	$chatusers = $chatusers.$temp;
	
}; // End foreach



}; // End $count_chatter >0


// surround the $chatusers with some table tags and assign it to a template var
$chatter['usernames'] = "<table><tr>".$chatusers."</tr></table>";

// assign the number of people to a templatevar, so that we can have some conditions on the forumhome-template
$chatter['count'] = $count_chatter;

will work.

thanks for helping! I never used the storing of the avatars in the filesystem, so I didn't know what to do.
I will analyse your script and try to implement it into mine in version 0.3
