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');

<?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>

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

The Moneyblog theme is really cool. I like the color green – definitely the color of money! I’m using this on my Random blog right now. Works great!

There are a lot more great wordpress themes listed on the original post. Do visit 1st Web Designer for the complete list!

I stumbled into Dave’s post about 10 plugins you can install on WordPress to make it a better CMS. Here is the list from his entry:

1. Page Link Manager – If you’re using WordPress as a CMS, it’s quite likely that you’ll be using pages instead of posts. The Page Link Manager plugin installs a simple menu that allows you to check which pages you want included in your main navigation.
2. My Page Order – Often, you’ll want to display your WordPress page navigation in a list, and you’ll probably want to have some control over the way those menu items display. My Page Order allows you to move pages around the list. It can also be used to move child pages around the navigation menu.
3. Widget Logic – This plugin allows you to display different widgets on different pages. So now you can display a specific set of widgets on your blog, another set on your home page, and yet another on your product pages. The plugin uses conditional tags to trigger the logic bit.
4. Yoast Breadcrumbs – Since the early days of the Internet, breadcrumbs have been used to show visitors where they are on your site. This simple plugin installs above your content and can easily be styled to suit your theme’s look.
5. Search Everything – The default WordPress search function searches only blog posts. On a CMS, you want both pages and posts to be searchable. Search Everything gives you this added functionality.
6. Analytics360 – I wasn’t going to add this one to my list, but 2 days into it, I’m loving having a Google Analytics system right on my WordPress Dashboard. Not only does the plugin display Google stats, it also shows when you published blog posts and can be integrated with the Mail Chimp e-mail management app. This one is great for blogs and corporate sites.
7. WP-CMS Post Control – Even though WordPress has a simple page editing interface, it can still get cluttered, especially for new users. The WP-CMS Post Control plugin lets you set which write panels appear in your editing pages, de-cluttering it beautifully.
8. Widgets Reloaded – 2 words. GET THIS. Justin Tadlock has created a widget set that pushes WordPress further than anything anyone has ever done before. In a nutshell, the plugin gives your widgets the ability to do anything. They’ll even make you coffee. OK, not really.
9. Flutter – I haven’t quite got to grips with Flutter yet, and the video tutorials on the Flutter site leave a lot to be desired, but the idea is brilliant. You can set write panels to do pretty much anything on a post or a page, including adding images, file uploads, video or content. So, for a company CMS with loads of repetitive page structures, the Flutter write panels could be a massive time saver.
10. Ozh’ Admin Drop Down Menu – This neat little plugin converts the WordPress admin panel’s navigation from the left of the page to simple drop down menus on the top of the dashboard. The result: All the plugins you’ve installed in steps 1-9 above are a heck of a lot easier to find.

I’ll definitely be using some of these plugins in the next website I would be making. Thanks Dave for the tips!
