Thought this would be straight forward... given a tag page such as http://domain.com/blog/tag/tag-1/ how can I retrieve the post_id while on that page?

The usual suspects such as url_to_postid and $post->ID or $wp_query->post->ID do not return anything. The hook that calls the function is running during init.

Thanks!

A tag page would be like other archive pages in that a loop of posts would be displayed, even if only one post has been assigned that tag.

You're check for post ID needs to happen during the <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> loop.

Ah... don't think I can do that since this is a plugin and not a theme. Is there any way I can treat a tag page differently from within my plugin? – Jonathan van Clute Oct 7 '11 at 4:23
You may want to look into using add_action( 'the_post', 'your_action_function' ); in your plugin. That hooks in and returns an array of post data to the specified function. – Jeremy Felt Oct 7 '11 at 4:41
AWESOME! That looks like it's precisely what I needed. Thanks!! – Jonathan van Clute Oct 7 '11 at 5:13
I've run into one unfortunate problem with this solution. The hook I need to use this with, must execute at one of several possible points, including init, wp_loaded, and a few others. Unfortunately all of these cause the passing of the post data to fail, and so I'm not able to pick up the fact that I'm on a tag page. Any idea how I can use is_tag or similar functions within init? – Jonathan van Clute Oct 7 '11 at 20:42
