Slashes, your solution worked wonderfully for me on my development site. I had a sidebar drop-down of four different taxonomies, ways to navigate a menu. But, when I moved to production, one of my drop-downs wouldn’t populate. I looked through all of my slugs to make sure there wasn’t a conflict, then I adjusted the ‘largest’ and ‘number’ inputs to see if they were set too low for my actual data. But, to no avail–I couldn’t figure out what the problem was.

Finally, I tried Hugo’s code and it worked first try.

Great work and thanks to both of you. What would we do without this open source community?

Thanks for this tutorial. I have come across an issue though. When selecting from the dropdown it shows the page of that term with the associated content, however I’m not sure which template it is calling.

I’m assuming it’s calling the archive.php template? Problem is that I have created seperate content type templates and now I want the taxonomy term page generated by the drop down to use the sample content type template. Short of creating taxonomy-mytax.php files what other solutions would you recommend?

Would it great if you could upload the full code online.

And thanks a ton to Slashas for the original code :)

<form>
<select name="tag-dropdown" onchange="document.location.href=this.options[this.selectedIndex].value;">
<option value='#'>Select Taxonomy terms</option>
$taxonomies = array('taxonomy-name');
$args = array('orderby'=>'name','hide_empty'=>true);
echo get_terms_dropdown($taxonomies, $args);
</select>
</form>

In functions.php add

function get_terms_dropdown($taxonomies, $args){
	$myterms = get_terms($taxonomies, $args);
	$output ="";
	foreach($myterms as $term){
		$root_url = get_bloginfo('url');
		$term_taxonomy=$term->taxonomy;
		$term_slug=$term->slug;
		$term_name =$term->name;
		$link = $root_url.'/'.$term_taxonomy.'/'.$term_slug;
		$output .="<option value='".$link."'>".$term_name."</option>";
	}
	$output .="";
return $output;
}

and then in the taxonomy template add:

Select Taxonomy terms

$taxonomies = array('taxonomy-name');
$args = array('orderby'=>'name','hide_empty'=>true);
echo get_terms_dropdown($taxonomies, $args);

Its a bit more flexible. Hope its helps wp developers.

Keep up the good work

//your code

Can i paste the code in the comment box?

I just started using taxonomies with this new version of wordpress, i think its a great way to group posts and easily manage them in wp admin panel and also use them as a suport navigation in a website. Aroundwp.com tutorial “Display custom taxonomy terms in a dropdown menu” was a staring point to explore taxonomies, really cool.

And what about custom post types? I will wait for a tutorial about this new wp feature.

Keep up with good work.
