Display WordPress Post Tags In A Dropdown Menu

We use this code here on WPswitch so you should to, or not..whatever!

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]
<?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 );
}
?>
[/php]

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

[php]
<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>
[/php]
