How to alter node title

"Have you looked at..."

Thank you for pointing me in the right direction. I have followed the instructions in the Readme and now have a custom view working with a "custom" menu path type for my vocabulary. I can produce a page with a static title (like the "Terms" title example in the Readme instructions). What I would like to do, though, is have the page title be just the first term in the %1 title parameter. When using a hierarchical taxonomy, the %1 parameter is constructed as a concatenation of all the relevant terms ("parent_term+child_term1+child_term2" etc.). Using %1 in the title field shows all those terms, resulting in a very messy title. Is there some way to parse out just the first term (parent_term) and use it as the title, and still display all the content for the entire hierarchy?

"many...require custom code"

Thanks again. That got me started, and I noodled my way to this post, which I used as a starting point: http://drupal.org/node/365418.

The attached images should explain what I did. If they don't, post back with questions.

My code works, but I'm still a rudimentary PHP coder, so any suggestions on how to tighten up the Validator code would be appreciated.

"don't you love drupal"

Yes, I do!

Edit: Yes, image #6 shows the "duplicate terms" problem as described in http://drupal.org/node/514640.

"This means, you create a view as a 'proxy'?"

Not sure how you are using the term "proxy", and I'm a Views newbie, but I think the answer to your questions is Yes. The key is the "path" field in the view, which says, "any time a page with this path construct is referenced, render it with this view". In this case, the only thing the View changes (via the Validator code) is the way the title is displayed.

"I'm also looking for a stable solution."

I guess this approach can be considered "stable" as long as the Views module and the path construct generated by Taxonomy Menu are "stable".

"What does the stuff in the Argument-Validator do?"

See commented code below.

if( $argument) {  //If an argument was passed, do the following
      $terms = explode(" ", arg(1));  //Parse the elements of the argument string into an array
      $names = taxonomy_get_term($terms[0]);  //The first argument/array element is the parent term's id, so use it to get the parent's taxonomy object
      $handler->options['title'] = 'Notices for '.$names->name; //Set the title to the name contained in the parent's taxonomy object so the page title will be just the name of the parent term
}
return true;  //Always return true to allow normal processing

"So the validation really is not doing any validation. It is just a convenient place to put some code to alter the view output, right?"

Correct
