Here is the code;

Insert this code into your theme’s functions.php;

//Category cloud
function nube(){
  $categories=  get_categories('child_of=0&type=post&orderby=name&number=500rand&order=asc');
  foreach ($categories as $category) {
	  $font=@intval($category->category_count/2);

	  $color="#000000";
	  if($font<10){
		  $font=10;
		  $color="#AAAAAA";
	  }
	  if($font>15 && $font<30){
		  $font=15;
		  $color="#8CC7FF";
	  }
	if($font>=30){
		$font=30;
		$color="#ff0000";
	}

	if($category->category_count>4){
  	$resp .= '<a title="Total Article: '.$category->category_count.'"style="font-size:'.$font.'px;color:'.$color.'" href="/category/'.$category->category_nicename.'">'.$category->cat_name.'</a> ';
			}
  }
  return $resp;

That’s All. Have a nice day!

Here is the code;

First Create an information and name area;

<?php
/*
Template Name: Archive page
*/
?>

After that add these lines for page template; with this code you list all your articles.

<?php
$posts_to_show = 100; //Max number of articles to display
$debut = 0; //The first article to be displayed
?>
<?php while(have_posts()) : the_post(); ?>
<h2><?php the_title(); ?></h2>
<ul>
<?php
$myposts = get_posts('numberposts=$posts_to_show&offset=$debut');
foreach($myposts as $post) :
?>
<li><?php the_time('d/m/y') ?>: <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>
</ul>
<?php endwhile; ?>

And add these lines for category and the others…

<?php while(have_posts()) : the_post(); ?>
<h2><?php the_title(); ?></h2>
<h2>Categories</h2>
<ul><?php wp_list_cats('sort_column=name&optioncount=1') ?></ul>
<h2>Monthly Archives</h2>
<ul><?php wp_get_archives('type=monthly&show_post_count=1') ?></ul>
<?php endwhile; ?>

Now, save the articles.php and upload to your template’s area. Go to Pages > New Page and select the Page Template with Archives.php.

That’s All…
