i tried this code, it is not giving me any 404 page instead it is giving me the same page back, now i think the submit buttons needs to be configured

function the_taxonomy_dropdown($taxonomy) {
  $id = "{$taxonomy}-dropdown";
  $terms = get_terms($taxonomy);
  echo "<select name=\"{$id}\" id=\"{$id}\">";
  foreach($terms as $term) {
    echo '<option value="';
    echo get_term_link(intval($term->term_id),$taxonomy);
    echo '">' . "{$term->name}</option>";
  echo "</select>";
function jquery_init() {

this code was provided to me by one of the person from this website, i just modified it, this works but its just showing me the home page again

Just a standard HTML form will do!

<form action="<?php echo home_url('/'); ?>" method="get">

    <p><?php wp_dropdown_categories('taxonomy=taxonomy-1&name=taxonomy-1'); ?></p>
    <p><?php wp_dropdown_categories('taxonomy=taxonomy-2&name=taxonomy-2'); ?></p>
    <p><input type="submit" value="Search!" /></p>


Just replace taxonomy-1 and taxonomy-2 with the names of your taxonomies.


If you registered your taxonomy with a custom query_var, you'll need to match it in the name argument of wp_dropdown_categories().

Also, querying multiple taxonomies is not supported as of 3.02 - you'll need the 3.1 beta, a plugin or additional filters.

    Did you install the plugin or additional filters as indicated? As has been said, multiple taxonomy queries are not supported "as is"..
