just had a look at the second method, and it seemed to work perfectly until I tried the select all option, which in effect does work, it shows all ‘posts’. Im using this script for a custom post type archive page, attempting to show a dropdown menu of the custom taxonomies.

Here is the code thats in my archive page…

and here is the function…

function custom_taxonomy_dropdown($taxonomy, $orderby, $order, $limit, $name, $show_option_all) {
	$args = array(
		'orderby' => $orderby,
		'order' => $order,
		'number' => $limit
	);
	$terms = get_terms($taxonomy, $args);
	echo '';
	if($show_option_all) echo ''.$show_option_all.'';
	if($show_option_none) echo ''.$show_option_none.'';
	foreach ($terms as $term) {
		echo 'slug.'">'.$term->name.'';
	}
	echo '';
}

The value="0" shows all the posts, but none of the custom post pages, all of the others work perfectly. Any ideas?

On a side note, someone asked about it submitting the form without a button, just add onchange="this.form.submit();" to the select element, works perfectly

The wp_dropdown_categories() function outputs value="0" for the show_option_all argument, so this should work.

Have you tried the Expansions on Method #2 example above?

//Frankie

function custom_taxonomy_dropdown($taxonomy) {
	$terms = get_terms($taxonomy);
	echo '';
		echo 'All';
	foreach ($terms as $term) {
		echo 'slug.'">'.$term->name.'';
	}
	echo '';
}

I’m guessing value="0" isn’t correct. Any ideas?

Someone was asking about how to get the form to submit, so you may want to complete this tutorial by adding the complete function that wordpress devs should add to their functions.php

For me this was:

function custom_taxonomy_dropdown($taxonomy, $name, $show_option_all) { ?>
	<form action="" method="get">
	 $orderby,
		'order' => $order,
		'number' => $limit
	);
	$terms = get_terms($taxonomy, $args);
	echo '';
	if($show_option_all) echo ''.$show_option_all.'';
	if($show_option_none) echo ''.$show_option_none.'';
	foreach ($terms as $term) {
		echo 'slug.'">'.$term->name.'';
	}
	echo '';
	?>
<?php }

Are you using it to do a search on the front-end?

Or are you using it in the WP Admin?

Thanks for the tutorial.

I think I’m having the same problem as the other Tim – the dropdown is populated OK but it doesn’t submit when an item is selected.

This is the code that I’m trying to use – a combination of your tutorial and the wp_dropdown_categories() tutorial I found in the Codex:

<form action="/" method="get">

Can you point me in the right direction?

Thanks,

Tim
