Display tags as cloud
Creates a cloud of your used tags. Didn't test on Drupal 4.6 but should work too.
Instead of this snippet you can just install the tagadelic module.
<?php
class tag
{
var $name = "";
var $count = 0;
var $tid = 0;
function getCount()
{
return $this->count;
}
function getName()
{
return $this->name;
}
function setCount($var)
{
$this->count = $var;
}
function setName($var)
{
$this->name = $var;
}
function setTID($var)
{
$this->tid = $var;
}
function getTID()
{
return $this->tid;
}
}
$count = 0; // Overall count of used tags
$threshold = 1; // How many tags are needed to get displayed
$font_size = 0.8;
$query = "SELECT d.name,d.tid FROM {term_data} d, {term_node} dn WHERE dn.tid=d.tid;";
$result = db_query($query);
$tags['Test'] = 0;
while($node = db_fetch_array($result))
{
if ($tags[$node['name']] == NULL)
{
$tags[$node['name']] = new tag();
$tags[$node['name']]->setName($node['name']);
$tags[$node['name']]->setCount(1);
$tags[$node['name']]->setTID($node['tid']);
$count = $count + 1;
}
else
{
$tags[$node['name']]->setCount(
$tags[$node['name']]->getCount() + 1
);
$count = $count + 1;
}
}
foreach($tags as $tag)
{
$mycount = $tag->count;
if($mycount > $threshold)
{
$fraction = ((int)(($mycount / $count) * 1000)) / 10;
if($fraction < $font_size)
{
$fraction = $font_size;
}
echo '<span style="font-size: ' . $fraction . 'em;">' . l($tag->name,'taxonomy/term/' . $tag->tid,array('title="' . $tag->count . ' Nodes"')) . '</span> ';
}
}
?>
In Drupal 5.1, for the font
In Drupal 5.1, for the font size to fit your block, one the latest line should be:
$fraction = ((int)(($mycount / $count) * 100)) / 10;instead of
$fraction = ((int)(($mycount / $count) * 1000)) / 10;This snippet does not check against taxonomy_access module
in drupal 4.7.x This snippet does not check against taxonomy_access module database. If you list a tag to not be listed on a node (via taxonomy_access module http://drupal.org/project/taxonomy_access) it will still show up as listed in this snippets cloud.
