Views Sort Criteria - Taxonomy Terms

I can't get this to work either. I have set the Taxonomy vocab to lowest weight and selected Taxonomy: Term Name and Asc in Sort Criteria. However this doesn't seem to work at all. The page displays them randomly. I'm trying to get it to sort the page nodes by Vocab 1, Alphabetically for the terms in vocab 1, Asc. Any ideas?

Sorting by taxonomy terms in a View isn't a stock function, at least when dealing with CCK content types.

Here's how to do it...

Make sure you have the right modules enabled:

Views: http://drupal.org/project/views
CCK Taxonomy: http://drupal.org/project/cck_taxonomy
Taxonomy Fields: http://drupal.org/project/taxonomy_fields

Create a vocabulary and assign it to the content type your View is displaying

Create terms in the vocabulary that you want to sort by, setting the weight to -10 for the highest ranking term, -9 for the next down and so on. You might want to add a "-None-" category.

Configure your View filter to the content type for the first filter, "Taxonomy: Terms for [your vocabulary name]" as the second. Set the Operator to "Is One Of" and highlight all the terms in the select box.

Add the sort criteria "Taxonomy: Term Name", Ascending

That's it. You are limited in the number of weight slots you have, but it's still useful.

does this help?
Requirements:

* Views: http://drupal.org/project/views
* CCK Taxonomy: http://drupal.org/project/cck_taxonomy
* Taxonomy Fields: http://drupal.org/project/taxonomy_fields

Now ORDER is crucial in views. The first filter should be the type of content; choose the type where you applied the terms to. It can be page type or any content type you created. Secondly, the next filter must be (the numbered) terms you associated with this content type. Add any other filters if required, but only after numbered term filter (named Order).

The next and final step is to add a sorting criteria. Since views does not allow specific 'sort by term', just add Taxonomy: Term Name in the Sorting Criteria (as seen below).

The sorting criteria sorts the first filtered term, then the second, followed by the third, and so on. Keeping that in mind, you can expand on this and create a custom hierarchal list of terms, oh my!

I do not know if this is the source of your issue but this confused me for a long time.

In views, when you pick sort by taxonomy, it sorts by the first taxonomy of that node, whether or not if shows up in the view.

I've been screwing around with making this work with computed field. It seems like Computed Field should be able to act on a node's taxonomy with something like this:

<?php

$lightest = 999999;
$vid = 12; //the vocabulary ID that you want to sort by

foreach ( $node->taxonomy as $term ){
	if ( ($term->vid == $vid ) && ( $term->weight < $lightest )  ){
		$lightest = $term->weight;
	}
}

$node_field[0]['value'] = $lightest;

?>

I'll admit that this didn't work for me. Perhaps computed field does not have access to $node->taxonomy when it performs it's computation? Either way, I had to change the code a little bit to draw the data from my CCK Taxonomy field like so:

<?php

$lightest = 999999;
foreach( $node->field_field_title as $equ ){
	if ($equ['value'] != ''){
		$term = taxonomy_get_term($equ['value']);
		if ( $term->weight < $lightest  ){
			$lightest = $term->weight;
		}
	}
}

$node_field[0]['value'] = $lightest;

?>

This works well for me for sorting in views.

Old post, but if you come here searching (like I did)
If using views, Sort by term weight was helpful.
