Tag Cloud
This article is also available in the following languages:
Here's a nice way to do a simple and customizable tag cloud.
First add a tag column to your table.
Add keywords separated by commas.
Here's the component: (nuage.php)
And here's the element: (nuage.thtml)
Do whatever you want with it and give me your comments.

Add keywords separated by commas.
Here's the component: (nuage.php)
Component Class:
<?php
<?php
class NuageComponent extends Object
{
var $controller = true;
function startup(&$controller)
{
$this->controller = &$controller;
$Articlez = new Article; //Model name
$data = $Articlez->query("SELECT article_tags AS tag FROM articles"); //Select only the tags column.
$this->controller->set('Tagz',$data);
}
}
?>
?>
And here's the element: (nuage.thtml)
View Template:
<?php
$mots = array();
foreach ($Tagz as $_tag) {
$tag = $_tag['articles']['tag'];
if ($tag):
if (stristr($tag, chr(44))) {
$tags = explode(chr(44), $tag);
foreach($tags as $__tag):
if(array_key_exists($__tag, $mots)) $mots[$__tag]++;
else $mots[$__tag] = '1';
endforeach;
}
else {
if(array_key_exists($tag, $mots)) $mots[$tag]++;
else $mots[$tag] = '1';
}
endif;
}
$max_size = 25; $max_weight = 900; //max font size and max font weight
$min_size = 5; $min_weight = 100; //min font size and min font weight
$max_qty = max(array_values($mots)); //the maximum data
$min_qty = min(array_values($mots)); //the minimum data
$spread = $max_qty - $min_qty;
if (0 == $spread) {
$spread = 1;
}
$step = ($max_size - $min_size)/($spread);
$bold = ($max_weight - $min_weight)/($spread);
foreach ($mots as $key => $value) {
$size = round($min_size + (($value - $min_qty) * $step),0);
$weight = round($min_weight + (($value - $min_qty) * $bold),0);
echo '<a href="/articles/tags/'.$key.'" style="font-weight: '.$weight.'; font-size: '.$size.'pt" title="'.$value.' articles avec le tag '.$key.'">'.$key.'</a> ';
}
?>

A component gets access to the controller that loaded it through the startup() method shown above. This method is called immediately after Controller::beforeFilter(). This allows you to set component properties in the beforeFilter method, which the component can act on in it’s startup() method.
Because CakePHP loads models in a lazy fashion, it's usually not a good idea to create model instances in components. If you need model data in a component, it's best to pass that data in through one of the component's methods:
<?php
class UsersController extends AppController
{
var $uses = array('Apple');
var $components = array('Foo');
function index()
{
$data = $this->Foo->doFoo($this->Apple->findAll());
}
}
?>
echo ''.$key.' ';
Just include in the "style" the "vertical-align: middle;" and everything tag is aligned around a vertical line.
Like http://www.misite.com/articles/tags/php
I did like "SELECT * from news WHERE tags LIKE '%php%'; but this will return all like php , phpnuke, cakephp.
Thanks
You can put something like this:
When you have you tag word in the link you can search in the database as the following way.
select tags from templates
where tags like '%,green'
UNION
select tags from templates
where tags like '%,green,'
UNION
select tags from templates
where tags like '%green,'
UNION
select tags from templates
where tags ='green';
