WordPress has a built in function, the_meta(), for outputting all custom fields. But this function is limited in that it doesn't always output all of them. For example, it misses custom fields added by plugins which begin with an _ underscore.

This bit of code uses an alternate function, get_post_custom() which will return all of them, and display all values. Good for debugging.

<h3>All Post Meta</h3>

<?php $getPostCustom=get_post_custom(); // Get all the data ?>

<?php
    foreach($getPostCustom as $name=>$value) {

        echo "<strong>".$name."</strong>"."  =>  ";

        foreach($value as $nameAr=>$valueAr) {
                echo "<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
                echo $nameAr."  =>  ";
                echo var_dump($valueAr);
        }

        echo "<br /><br />";

    }
?>

Right before the closing of the The Loop, insert this code:

<?php
if (($wp_query->current_post + 1) < ($wp_query->post_count)) {
   echo '<div class="post-item-divider">Post Divider</div>';
}
?>

This will create a <div> you can style as a post divider. The cool part being, it only gets inserted between two posts, skipping the last one. Thanks to Craig Maclean.

<?php
$posttags = get_the_tags(); // Get articles tags
$home = get_bloginfo('url'); // Get homepage URL

// Check tagslug.png exists and display it
if ($posttags) {
 foreach($posttags as $tag) {
       $image = "http://cdn.css-tricks.com/images/tag-images/$tag->slug.png";

       if (file_exists("images/tag-images/$tag->slug.png")) {
         echo '<a href="' . $home . '/tag/' . $tag->slug . '" /><img title="' . $tag->name . '" alt="' . $tag->name . '" src="' . $image . '" /></a>';

       // If no image found, output something else, possibly nothing.
       } else {
         echo '<p>Not found</p>';
       }
  }
}
?>

This code belongs inside the loop. It will look in a specific directory for any images that match the slugs of article tags, display them and link them to the relevant tag archive.

The image that shows for the author comes from the email address set for that user which goes to a corresponding Gravatar. The display name and bio come from the User settings area in the Admin.

<div class="author-box">
   <div class="author-pic"><?php echo get_avatar( get_the_author_email(), '80' ); ?></div>
   <div class="author-name"><?php the_author_meta( "display_name" ); ?></div>
   <div class="author-bio"><?php the_author_meta( "user_description" ); ?></div>
</div>

That should be all the CSS hooks you need to style up the area however you want. Note: some of these functions are WordPress 2.8 and newer only.

<?php wp_tag_cloud( array(

    'smallest' => 8,          // font size for the least used tag
    'largest'  => 22,         // font size for the most used tag
    'unit'     => 'px',       // font sizing choice (pt, em, px, etc)
    'number'   => 45,         // maximum number of tags to show
    'format'   => 'flat',     // flat, list, or array. flat = spaces between; list = in li tags; array = does not echo results, returns array
    'orderby'  => 'name',     // name = alphabetical by name; count = by popularity
    'order'    => 'ASC',      // starting from A, or starting from highest count
    'exclude'  => 12,         // ID's of tags to exclude, displays all except these
    'include'  => 13,         // ID's of tags to include, displays none except these
    'link'     => 'view',     // view = links to tag view; edit = link to edit tag
    'taxonomy' => 'post_tag', // post_tag, link_category, category - create tag clouds of any of these things
    'echo'     => true        // set to false to return an array, not echo it

) ); ?>

The default sizing, if none supplied, for this function is "pt" which is a bit unusual and often unreliable so make sure you change that parameter to how you size fonts normally on your site.

Less Weird Font Sizing

Tag clouds accomplish their varied font sizes by applying inline styling to each tag. The resulting font sizes can be really weird like style='font-size:29.3947354754px;'. Mike Summers proposes this solution:

<div id="tagCloud">
	<ul>
		<?php
			$arr = wp_tag_cloud(array(
				'smallest'             => 8,                      // font size for the least used tag
				'largest'                => 40,                    // font size for the most used tag
				'unit'                      => 'px',                 // font sizing choice (pt, em, px, etc)
				'number'              => 200,                 // maximum number of tags to show
				'format'                => 'array',            // flat, list, or array. flat = spaces between; list = in li tags; array = does not echo results, returns array
				'separator'          => '',                      //
				'orderby'              => 'name',           // name = alphabetical by name; count = by popularity
				'order'                   => 'RAND',          // starting from A, or starting from highest count
				'exclude'              => '',                      // ID's of tags to exclude, displays all except these
				'include'               => '',                      // ID's of tags to include, displays none except these
				'link'                       => 'view',             // view = links to tag view; edit = link to edit tag
				'taxonomy'         => 'post_tag',    // post_tag, link_category, category - create tag clouds of any of these things
				'echo'                    => true                 // set to false to return an array, not echo it
			));
			foreach ($arr as $value) {
				$ptr1 = strpos($value,'font-size:');
				$ptr2 = strpos($value,'px');
				$px = round(substr($value,$ptr1+10,$ptr2-$ptr1-10));
				$value = substr($value, 0, $ptr1+10) . $px . substr($value, $ptr2);
				$ptr1 = strpos($value, "class=");
				$value = substr($value, 0, $ptr1+7) . 'color-' . $px . ' ' . substr($value, $ptr1+7);
				echo '<li>' . $value . '</li> ';
			}
		?>
	</ul>
</div>

The result turns this:

<a href='url' class='tag-link-66' title='6 topics' style='font-size:29.3947354754px;'>Tag Name</a>

into this:

<a href='url' class='color-29 tag-link-66' title='6 topics' style='font-size:29px;'>Tag Name</a>

Notice the added bonus that the links has a class name of "color-29" now that it didn't before. Now you have a hook to colorize tag names based on their size.

       }

       return $new_content;
}

remove_filter('the_content', 'wpautop');
remove_filter('the_content', 'wptexturize');

add_filter('the_content', 'my_formatter', 99);

This goes in the PHP in your functions.php file. Once done, you can use the [raw] shortcode in your posts: [raw]Unformatted code[/raw]
