Changing taxonomy with actions

Hello agent,

did you managed to get this to work?..i am actually looking for the same exact thing!

Any hint or help apreciated :)

I'm interested in this too. Combined with CCK, this would enable a magazine or newsletter publishing workflow. Categories instead of taxonomy would be fine, as I'm considering moving to that module.

This is not changing the term but it is close to what you need I think. I created a quick custom action to add a taxonomy term to a node. It is just doing a simple DB insert into the term_node table. It also gives you a configuration screen to indicate which ID number you want to use. There is probably a better way to do this but it works me right now.

I put this code (along with a few other custom actions) into a module I creatively called customActions.module. You should be able to edit this to do other SIMPLE taxonomy changes by simply changing the db_query to swap out the term id (SQL UPDATE) or remove (SQL DELETE) with whatever logic you want.

Hope it helps someone.

<?php
function action_taxonomy($op, $edit = array(), &$node) {
    switch ($op) {
        case 'metadata' :
            return array (
                'description' => t('Add a taxonomy term to a node'), 
                'type' => t('Node'), 
                'batchable' => false, 
                'configurable' => true);

        case 'do' :
            if(!isset($edit['term'])){
                // log
                watchdog('error', t('Action Term: no term has been identified!'));
                break;               
            }
            // get the term we added in config
            $termID = $edit['term'];

            // log
            watchdog('action', t('Added term ID '.$termID.' to node "'.$node->title.'".'));

            // insert the new nid-tid association in the db
            db_query('INSERT into {term_node} (nid,tid) VALUES (%d,%d)', $node->nid, $termID);

            break;

            // return an HTML config form for the action
        case 'form' :
            // default values for form
            $form = array ();

            $form['term'] = array (
                '#type' => 'textfield',
                '#title' => 'Term to add',
                '#default_value' => $edit['term'],
                '#maxlength' => 5,
                '#collapsible' => FALSE,
                '#required' => TRUE,
                '#description' => t('Enter the taxonomy term ID number that you would like added to the node. Just the number, NO slashes or text!'),
                );
           
            return $form;

            // validate the HTML form
        case 'validate' :
            $errors = array ();

            foreach ($errors as $name => $message) {
                form_set_error($name, $message);
            }

            return count($errors) == 0;

            // process the HTML form to store configuration
        case 'submit' :

            $params = array (
                'term' => $edit['term'],
            );
            return $params;
    }
}
