Custom Post Types Permalinks

I just had the same problem on my page with two custom post types and ~10 custom taxonomies. Either I could access the custom post types/taxonomies but not the standard pages (although posts were okay).

I have seen a recommendation somewhere on not using /%postname%/ as permalink structure, but as I was using /%year%/%monthnum%/%postname%/ I didn’t think that would affect me.

As I messed around with my register_post_type arguments I tried changing the rewrite setting from true into 'rewrite' => array( 'slug' => 'film', 'with_front' => false )

That didn’t change anything at first, but it got me thinking I should try adding a url base, so I changed my permalink structure into /foobar/%year%/%monthnum%/%postname%/. This solved my problem, pages started to show up as well as custom post types (which I could access at /film/king-kong/ as intended).

But I didn’t want the url base in all my URLs, for example I would like to access pages at /%postname%/. To accomplish this I changed the permlink structure once again into /%category%/%year%/%monthnum%/%postname%/ which seems to be working out fine. My permalinks now looks like this:

Pages: /page-name/
Blog posts: /blog/2010/08/post-title/
Custom post types: /post-type/post-title/
Custom taxonomies: /taxonomy-slug/tag-slug/

It seems that once you add custom post types you might get rewrite collisions between custom and built in types, depending on your permalink settings.

I have a theme in the repo that handles all this:

I basically used Jake Goldman’s plugin as a drop in:
http://wordpress.org/extend/plugins/simple-custom-post-type-archives/

add_action('init', 'my_rewrite');
function my_rewrite() {
    global $wp_rewrite;
    $wp_rewrite->add_permastruct('typename', 'typename/%year%/%postname%/', true, 1);
    add_rewrite_rule('typename/([0-9]{4})/(.+)/?$', 'index.php?typename=$matches[2]', 'top');
    $wp_rewrite->flush_rules(); // !!!
}

$wp_rewrite->flush_rules(); // !!!

@digimat1 – sorry for the late response. i’m still experiencing the error when the permalink structure is %postname%. it works fine with all the other structures – as long as you “resave” the permalink settings.

<?php
add_action('init', 'my_custom_post_type_init');
function my_custom_post_type_init()
{
  $labels = array(
    'name' => _x('Roundabouts', 'post type general name'),
    'singular_name' => _x('Roundabout', 'post type singular name'),
    'add_new' => _x('Add New', 'Roundabout'),
    'add_new_item' => __('Add New Roundabout'),
    'edit_item' => __('Edit Roundabout'),
    'new_item' => __('New Roundabout'),
    'view_item' => __('View Roundabout'),
    'search_items' => __('Search Roundabouts'),
    'not_found' =>  __('No Roundabouts found'),
    'not_found_in_trash' => __('No Roundabouts found in Trash'),
    'parent_item_colon' => ''
  );
  $args = array(
    'labels' => $labels,
    'public' => true,
    'publicly_queryable' => true,
    'show_ui' => true,
    'query_var' => true,
    'rewrite' => true,
    'capability_type' => 'post',
    'hierarchical' => false,
    'menu_position' => 5,
    'menu_icon' => get_stylesheet_directory_uri() . '/images/arrow-circle-225.png',
    'rewrite' => array('slug' => 'roundabouts', 'with_front' => false),
    'taxonomies' => array( 'post_tag', 'category '),
    'supports' => array('title','editor','author','thumbnail','excerpt','comments', 'thumbnail')
  );
  register_post_type('roundabouts',$args);
}
?>

wpAdm’s solution was PERFECT for me.
When I changed the permalink structure, I was fine EXCEPT for custom taxonomies, which led to 404s.
I just put wpAdm’s code in functions.php and all is fine now.

can we have a little bit more instruction on how to use that code that wpAdm pasted? Are you supposed to put your cutom post type name in place of ‘typename’? what does each parameter of the functions do? I am having trouble getting it to work.

i actually skipped wpAdm’s solution for the default rewrite param (within my_custom_post_type_init) which works with most types of permalink structure

All I want to do is add a folder name (music) before all the different post types and taxonomies that fall into that section, like…..

mysite.com/music/bands/post-name
mystie.com/music/shows/post-name
mysite.com/music/venues/post-name

With a taxonomy….
mysite.com/music/venues/out-door/post-name
