Really enjoying this mod, everything works fine and my members are loving it. I had a idea and i suggested this on TinyPortal but we can't seem to get it working so i need a little help..
I wanted to show the Tag Cloud in a block code snippet, and member JPDeni suggested to use this code in a phpbox:
global $db_prefix, $scripturl, $context;
$query = "SELECT t.tag AS tag, l.ID_TAG, COUNT(l.ID_TAG) AS quantity
FROM {$db_prefix}tags as t, {$db_prefix}tags_log as l WHERE t.ID_TAG = l.ID_TAG
GROUP BY l.ID_TAG
ORDER BY l.ID DESC LIMIT 50";
$result = db_query($query, __FILE__, __LINE__);
$tags = array();
$tags2 = array();
while ($row = mysql_fetch_array($result))
{
$tags[$row['tag']] = $row['quantity'];
$tags2[$row['tag']] = $row['ID_TAG'];
}
if(count($tags2) > 0)
{
// change these font sizes if you will
$max_size = 250; // max font size in %
$min_size = 100; // min font size in %
// get the largest and smallest array values
$max_qty = max(array_values($tags));
$min_qty = min(array_values($tags));
// find the range of values
$spread = $max_qty - $min_qty;
if (0 == $spread)
{ // we don't want to divide by zero
$spread = 1;
}
// determine the font-size increment
// this is the increase per tag quantity (times used)
$step = ($max_size - $min_size)/($spread);
// loop through our tag array
$context['poptags'] = '';
$row_count = 0;
foreach ($tags as $key => $value)
{
$row_count++;
// calculate CSS font-size
// find the $value in excess of $min_qty
// multiply by the font-size increment ($size)
// and add the $min_size set above
$size = $min_size + (($value - $min_qty) * $step);
// uncomment if you want sizes in whole %:
// $size = ceil($size);
// you'll need to put the link destination in place of the #
// (assuming your tag links to some sort of details page)
$context['poptags'] .= '<a href="' . $scripturl . '?action=tags;id=' . $tags2[$key] . '" style="font-size: '.$size.'%"';
// perhaps adjust this title attribute for the things that are tagged
$context['poptags'] .= ' title="'.$value.' things tagged with '.$key.'"';
$context['poptags'] .= '>'.$key.'</a> ';
if ($row_count > 5)
{
$context['poptags'] .= '<br />';
$row_count =0;
}
}
}
