Description

By default, custom post types uses only the %postname% permalink structure (if using pretty links and not default query variables).
Currently there is no native way to easily have different permastructs for different CPT.

This features should be added to the register_post_type() function, letting different permalink structure be defined to each post_type being registered.

I sugget adding another new key to the rewrite array that can be passed to the register_post_type() function.

i.e. -

register_post_type('event',array(
......
'rewrite' => array('slug' => 'events', 
	   'permastruct' => '%year%/%monthnum%/%event%'
	),
.....
));

The register_post_type function should be changed, a suggestion for such a change may be that instead of this line in the function - (post.php line#1075)

add_permastruct( $post_type, "{$args->rewrite['slug']}/%$post_type%", $args->rewrite );

This example could be used -

if (  $args->rewrite['permastruct'] )	{			
			$perma_structure = $args->rewrite['permastruct'];			
			$wp_rewrite->add_rewrite_tag("%{$post_type}%", '([^/]+)', "{$post_type}=");
			$wp_rewrite->add_permastruct($post_type, $archive_slug.'/'.$perma_structure, false);	
		}
		else	{
			add_permastruct( $post_type, "{$args->rewrite['slug']}/%$post_type%", $args->rewrite );			
		}

In order that the structure can interpret the permastruct tags, I added also this function to filter post_type_link, it is adapted from get_permalink function in wp-includes/link-template.php -

add_filter('post_type_link', 'tc_permalink', 10, 3);	
function tc_permalink($permalink, $post_id, $leavename) {
	$post = get_post($post_id);
	$rewritecode = array(
		'%year%',
		'%monthnum%',
		'%day%',
		'%hour%',
		'%minute%',
		'%second%',
		$leavename? '' : '%postname%',
		'%post_id%',
		'%category%',
		'%author%',
		$leavename? '' : '%pagename%',
	);
 
	if ( '' != $permalink && !in_array($post->post_status, array('draft', 'pending', 'auto-draft')) ) {
		$unixtime = strtotime($post->post_date);
 
		$category = '';
		if ( strpos($permalink, '%category%') !== false ) {
			$cats = get_the_category($post->ID);
			if ( $cats ) {
				usort($cats, '_usort_terms_by_ID'); // order by ID
				$category = $cats[0]->slug;
				if ( $parent = $cats[0]->parent )
					$category = get_category_parents($parent, false, '/', true) . $category;
			}
			// show default category in permalinks, without
			// having to assign it explicitly
			if ( empty($category) ) {
				$default_category = get_category( get_option( 'default_category' ) );
				$category = is_wp_error( $default_category ) ? '' : $default_category->slug;
			}
		}
 
		$author = '';
		if ( strpos($permalink, '%author%') !== false ) {
			$authordata = get_userdata($post->post_author);
			$author = $authordata->user_nicename;
		}
 
		$date = explode(" ",date('Y m d H i s', $unixtime));
		$rewritereplace =
		array(
			$date[0],
			$date[1],
			$date[2],
			$date[3],
			$date[4],
			$date[5],
			$post->post_name,
			$post->ID,
			$category,
			$author,
			$post->post_name,
		);
		$permalink = str_replace($rewritecode, $rewritereplace, $permalink);
	} else { // if they're not using the fancy permalink option
	}
	return $permalink;
}

On a basic check this seems to be working, but ofcourse needed to be more deubgged.. I will be happy to here if you think such a feature should be added to core.
