Display Tags In A Dropdown Menu

In your theme folder, paste the following code to the functions.php file. If you don’t have a functions.php file, create one.

<?php
function dropdown_tag_cloud( $args = '' ) {
	$defaults = array(
		'smallest' => 8, 'largest' => 22, 'unit' => 'pt', 'number' => 45,
		'format' => 'flat', 'orderby' => 'name', 'order' => 'ASC',
		'exclude' => '', 'include' => ''
	);
	$args = wp_parse_args( $args, $defaults );

	$tags = get_tags( array_merge($args, array('orderby' => 'count', 'order' => 'DESC')) ); // Always query top tags

	if ( empty($tags) )
		return;

	$return = dropdown_generate_tag_cloud( $tags, $args ); // Here's where those top tags get sorted according to $args
	if ( is_wp_error( $return ) )
		return false;
	else
		echo apply_filters( 'dropdown_tag_cloud', $return, $args );
}

function dropdown_generate_tag_cloud( $tags, $args = '' ) {
	global $wp_rewrite;
	$defaults = array(
		'smallest' => 8, 'largest' => 22, 'unit' => 'pt', 'number' => 45,
		'format' => 'flat', 'orderby' => 'name', 'order' => 'ASC'
	);
	$args = wp_parse_args( $args, $defaults );
	extract($args);

	if ( !$tags )
		return;
	$counts = $tag_links = array();
	foreach ( (array) $tags as $tag ) {
		$counts[$tag->name] = $tag->count;
		$tag_links[$tag->name] = get_tag_link( $tag->term_id );
		if ( is_wp_error( $tag_links[$tag->name] ) )
			return $tag_links[$tag->name];
		$tag_ids[$tag->name] = $tag->term_id;
	}

	$min_count = min($counts);
	$spread = max($counts) - $min_count;
	if ( $spread <= 0 )
		$spread = 1;
	$font_spread = $largest - $smallest;
	if ( $font_spread <= 0 )
		$font_spread = 1;
	$font_step = $font_spread / $spread;

	// SQL cannot save you; this is a second (potentially different) sort on a subset of data.
	if ( 'name' == $orderby )
		uksort($counts, 'strnatcasecmp');
	else
		asort($counts);

	if ( 'DESC' == $order )
		$counts = array_reverse( $counts, true );

	$a = array();

	$rel = ( is_object($wp_rewrite) && $wp_rewrite->using_permalinks() ) ? ' rel="tag"' : '';

	foreach ( $counts as $tag => $count ) {
		$tag_id = $tag_ids[$tag];
		$tag_link = clean_url($tag_links[$tag]);
		$tag = str_replace(' ', '&nbsp;', wp_specialchars( $tag ));
		$a[] = "\t<option value='$tag_link'>$tag ($count)</option>";
	}

	switch ( $format ) :
	case 'array' :
		$return =& $a;
		break;
	case 'list' :
		$return = "<ul class='wp-tag-cloud'>\n\t<li>";
		$return .= join("</li>\n\t<li>", $a);
		$return .= "</li>\n</ul>\n";
		break;
	default :
		$return = join("\n", $a);
		break;
	endswitch;

	return apply_filters( 'dropdown_generate_tag_cloud', $return, $tags, $args );
}
?>

Now open the file where you want the list to be displayed and paste the following code:

<select name="tag-dropdown" onchange="document.location.href=this.options[this.selectedIndex].value;">
	<option value="#">Tags</option>
	<?php dropdown_tag_cloud('number=0&order=asc'); ?>
</select>

Get Posts Published Between Two Particular Dates

Just before the loop starts, paste the following code. Change the dates on line 3 according to your needs.

<?php
  function filter_where($where = '') {
        $where .= " AND post_date >= '2009-05-01' AND post_date <= '2009-05-15'";
    return $where;
  }
add_filter('posts_where', 'filter_where');
query_posts($query_string);
?>

Get Posts With A Specific Custom Field & Value

Add the query_posts() function just before the Loop. Change the meta_key and meta_value accordingly. The example shown below will get posts with custom field “review_type” with value “movie”.

<?php query_posts('meta_key=review_type&meta_value=movie');  ?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
...
...

Get Latest Sticky Posts

Paste the following code before the loop. This code will retrieve the 5 most recent sticky posts. To change the number of retrieved posts, just change the 5 by the desired value on line 4.

<?php
	$sticky = get_option('sticky_posts');
	rsort( $sticky );
	$sticky = array_slice( $sticky, 0, 5);
        query_posts( array( 'post__in' => $sticky, 'caller_get_posts' => 1 ) );
?>

Automatically Insert Content In Your Feeds

In your theme folder, functions.php file, paste the following code. This code will automatically insert the content after each post in your RSS feeds. Hence you can use this code to insert ads or promotional text.

function insertFootNote($content) {
        if(!is_feed() && !is_home()) {
                $content.= "<h4>Enjoyed this article?</h4>";
                $content.= "<p>Subscribe to our <a href='#'>RSS feed</a></p>";
        }
        return $content;
}
add_filter ('the_content', 'insertFootNote');

Display The Most Commented Posts

Just paste the following code in your template file where you want to display the most commented posts (eg. sidebar.php). To change the number of displayed posts, simply change the 5 on line 3.

<?php $result = $wpdb->get_results("SELECT comment_count,ID,post_title FROM $wpdb->posts ORDER BY comment_count DESC LIMIT 0 , 5");
foreach ($result as $post) {
setup_postdata($post);
$postid = $post->ID;
$title = $post->post_title;
$commentcount = $post->comment_count;
if ($commentcount != 0) { ?>

<li><a href="<?php echo get_permalink($postid); ?>" title="<?php echo $title ?>">
<?php echo $title ?></a> {<?php echo $commentcount ?>}</li>
<?php } } ?>

</ul>

foreach ($result as $topten) {
    $postid = $topten->ID;
    $title = $topten->post_title;
    $commentcount = $topten->comment_count;
    if ($commentcount != 0) {
    ?>
         <li><a href="<?php echo get_permalink($postid); ?>"><?php echo $title ?></a></li>

    'showposts'=>5,
    'caller_get_posts'=>1
   );
  $my_query = new WP_Query($args);
  if( $my_query->have_posts() ) {
    while ($my_query->have_posts()) : $my_query->the_post(); ?>

      <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>

If you’re a Worpress Theme addict and you’ve not yet visited this post, I suggest you do because these are some of the best Premium-like WordPress Themes available. I’ve gone through the list, and 90% of it I really like. Especially the themes Magiting, Matiyaga, Mainam and Marangal from Padd Solutions (a fellow Pinoy web development firm). I’ve already bookmarked it, and I think you should too. Here are some of the WordPress themes I plan to use in my future projects:

Folio Elements WordPress Theme

I really like this theme. Simple, minimalist, dark Portfolio wordpress theme. I plan to use this for my design portfolio with some modifications.

Vodpod WordPress Theme

Moneyblog WordPress Theme

About 10 years ago, I used to crop my images using MS Paint because either image editing software were expensive or my slow computer cannot compliment the requirements of Adobe Photoshop 1. But nowadays online image editors are now available, and they are far more better than p..p..Paint. Here are 5 online image editors that designers should bookmark.

• SumoPaint
• Aviary Phoenix
• Photoshop.com
• Pixlr
• Splashup

Some of them have a similar look and feel as Photoshop, and can integrate with other online photo sharing services like Flickr and Picasa.

For brief descriptions, screenshots, and pros & cons of these great online image editors, visit this post at Web Resource Depot.
