Better Method of a Member Cloud

[Cultureshock]

I assume most people know how tag clouds work, where the tags most used are bigger and the least used tags are smaller. This is the basic function of my member cloud.

 

I created the code below from scratch, however I'd rather the data compare itself to each other and have the biggest poster the biggest font size (40px) and the smallest poster the smaller font size (15px) and everyone in between where they should be.

 

Assume the limit was 5 instead of 20 as in the code.

If:

Member 1 has 10 posts

Member 2 has 11 posts

Member 3 has 12 posts

Member 4 has 13 posts

Member 5 has 14 posts

 

I'd want Member 1 to be 15px and member 5 to be 40px, and everyone in between where they should be (I assume this would involve percentages.)

 

A more accurate/ more likely example:

Member 1 has 50 posts

Member 2 has 2 posts

Member 3 has 72 posts

Member 4 has 90 posts

Member 5 has 54 posts

 

I'd want Member 2 to be 15px and member 4 to be 40px, and everyone in between where they should be, regardless of what there actual post count is. I just want smallest smallest and largest largest.

 

 

 

 

$allmembersresult = mysql_query("SELECT * FROM users ORDER BY RAND() DESC LIMIT 20");
while($row = mysql_fetch_array($allmembersresult)){
$newuid = $row['id'];
$newusername = $row['username'];
$ifadmin = $row['admin'];

$postnumresult = mysql_query("SELECT * FROM content WHERE uid='$newuid' GROUP BY cid");
$postnum = mysql_num_rows($postnumresult);

?>

<a href="/us.php?find=<?php echo $newuid;?>" style="text-transform:none;
<?php
if($postnum == 0){
echo "font-size:15px;";
}else if($postnum > 0 && $postnum <= 5){
echo "font-size:20px;";
}else if($postnum > 5 && $postnum <= 15){
echo "font-size:30px;";
}else if($postnum > 15 && $postnum <= 30){
echo "font-size:40px;";
}; 

/* etcetc */

if($ifadmin == "yes"){
echo "font-style:italic;font-family:georgia;";
};
if($uid == "$newuid"){
echo "color:green;";
};
?>
">
<?php echo $newusername." (".$postnum.")"; ?>
, </a> 

<?php }; ?>

 

I'd be happy to elaborate if need be! thanks!

yeah it doesnt make sense to do it by post count.. i mean if people post a lot they will all be 40px

[Cultureshock]

Exactly why I'd want it to be a compared/ percentage size and not a standard/ fixxed size...

[emopoops]

to find the percentage ud need to like do something with the find the highest post count that a user has and then find the lowest post count which may in fact b zero, then make an array of averages or something

[Cultureshock]

I'm aware.

Now if someone who knows how to do that would help me...

function getCloud( $data = array(), $minFontSize = 12, $maxFontSize = 30 )
{
$minimumCount = min($data);
$maximumCount = max($data);
$spread       = $maximumCount - $minimumCount;
$cloudHTML    = '';
$cloudTags    = array();

$spread == 0 && $spread = 1;

foreach( $data as $tag => $count )
{
	$size = $minFontSize + ( $count - $minimumCount )
		* ( $maxFontSize - $minFontSize ) / $spread;
	$cloudTags[] = '<a style="font-size: ' . floor( $size ) . 'px'
	. '" class="tag_cloud" href="#" title="\'' . $tag  .
	'\' returned a count of ' . $count . '">'
	. htmlspecialchars( stripslashes( $tag ) ) . '</a>';
}

return join( "\n", $cloudTags ) . "\n";
}
