(Hierarchical) Custom Post Type & Taxonomy Permalinks
I've a custom post type 'books', a registered taxonomy 'book_taxonomy' and some trouble with my permalinks:
I'd like my permalinks for the cpt 'books' look like this:
domain.com/baseurl/--> static page with custom template
domain.com/baseurl/[book genre]/[book name]/ --> book-article
domain.com/baseurl/[book genre]/ --> archive of all book-articles matching 'book genre'
The Cherry on the cake would be a support of hierarchical taxonomies. E.g.:
domain.com/baseurl/[book genre]/[book sub genre]/[book name]/ --> book-article
domain.com/baseurl/[book genre]/[book sub genre]/[...]/[book name]/ --> book-article
After 'some' unsuccessful trial and error attempts based on snippets and tutorials I found on the web, I would be very thankfull for your help:-)
I think the only PHP you can use from my attempts, is this:
add_action('init', 'post_type_books');
function post_type_books() {
register_post_type('books',
array(
'labels' => array('name' => __('Books')),
'public' => true,
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'query_var' => true,
'rewrite' => array('with_front'=>false)
)
);
}
add_action( 'init', 'taxonomy_books', 0 );
function taxonomy_books() {
register_taxonomy ('book_taxonomy',array('books'),
array(
'labels' => array('name' => __('Genre')),
'show_ui' => true,
'hierarchical' => true,
'query_var' => true,
'rewrite' => false
)
);
} Supplement: Well, I've forgot to say that I'm not looking for a plugin-based solution... I'd like to "hardcode" it to my functions.php :-)

mark says:Well, no: that doesn't have any effect... I think it's not that simple:-(
I'm sure we'll have to add a filter with some new rewrite rules for the cpt. But I don't know how this filter should look like... - 06/16/12 3:09pm
Arnav Joy says:write this after the above code in functions.php
flush_rewrite_rules(); - 06/16/12 3:15pm
Arnav Joy says:or try this
function my_em_rewrite_flush(){
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
add_action('init','my_em_rewrite_flush'); - 06/16/12 3:22pm
Arnav Joy says:try this

Arnav Joy says:you can check this plugin
http://wordpress.org/extend/plugins/permalinks-for-hierarchical-custom-post-types/ - 06/16/12 4:25pm
mark says:Hey Arnav,
thanks for your help, but I think this isn't the way we'll get it to work :-) I'm quite sure we'll HAVE to set up and add some specific rewrite rules.
Somthink like this or maybe not:
global $wp_rewrite;
$book_structure = '/mybooks/%book_taxonomy%/%books%';
$wp_rewrite->add_rewrite_tag("%books%", '([^/]+)', "books=");
$wp_rewrite->add_permastruct('books', $book_structure, false);
And we'll have to add a filter to translate the permalink tags. Somthink like that could be found here:
http://shibashake.com/wordpress-theme/custom-post-type-permalinks-part-2
But as I said: I already worked on an trial and error 'method' on this for 'some' hours and couldn't get it working.
Flushing the rules without defining new ones can not have any effect - am I wrong?
BTW, another question: Is there any difference between
andflush_rewrite_rules();
? In the past I've only used the first one...
function my_em_rewrite_flush(){
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
add_action('init','my_em_rewrite_flush');
Plugin: As I wrote, I'm not looking for a plugin-based solution... I realy NEED to hardcode the rules into my functions.php :-/

mark says:Hey Daniel,
Wow, what a monster*... and a realy good start! :-) :-) :-)
- this code works perfectly for cpt posts with extactly two selected hierachical (sub)categories :-)
but...
- it doesn't work if only a maincategory is selected (or the category-depth is deeper then 2)
- it doesn't show archive-pages for links like
domain.com/mybooks/[book genre]/ --> archive of all book-articles matching 'book genre'
Any Ideas how we can achieve that? This last point is very important for me. Currently the homepage shows up when requesting an URL like "mysite.com/mybooks/sciencefiction/", but I'd like to see an achive-page of all scifi-books (shown by the matching template 'achive-books.php')
*) I removed all the unnecessary code and 'slimmed' it a little bit (still works like the code above):
function swi_post_type_books(){
register_post_type('books', array(
'labels' => array(
'name' => __('Books')
),
'public' => true,
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'query_var' => true,
'publicly_queryable' => true,
'query_var' => true,
'rewrite' => false
)
);
register_taxonomy('books_taxonomy', array('books'),
array(
'labels' => array(
'name' => __('Genre')
),
'show_ui' => true,
'hierarchical' => true,
'query_var' => true,
'rewrite' => false
)
);
}
function swi_custom_rewrite_post_type(){
global $wp_rewrite;
add_rewrite_tag('%books_cat%', '([^/]+)');
add_rewrite_tag('%books_subcat%', '([^/]+)');
$books_structure = '/mybooks/%books_cat%/%books_subcat%/%books%';
$wp_rewrite->add_rewrite_tag("%books%", '([^/]+)', "books=");
$wp_rewrite->add_permastruct('books', $books_structure, false);
}
function swi_books_permalink($permalink, $post_id, $leavename){
$post = get_post($post_id);
$rewritecode = array(
'%books_cat%',
'%books_subcat%'
);
if ('' != $permalink && !in_array($post->post_status, array('draft','pending','auto-draft'))){
$books_cat = '';
$cat_parent = '';
if (strpos($permalink, '%books_cat') !== false){
$terms = wp_get_object_terms($post->ID, 'books_taxonomy');
if (!is_wp_error($terms) && !empty($terms)) {
foreach ($terms as $term){
if ($term->parent == 0) {
$books_cat = $term->slug;
$cat_parent = $term->term_id;
break;
}
}

mark says:Hey Daniel,
sorry to say, but: no effect :-/
The code isn't able to "decide" whether to call an archive OR an post...
As I read the php the book-permalink structure is still "static" (/mybooks/%cat%/%subcat%). So it works only if exactly 2 hierachical categories are selected:-(
I think we need somthing more flexible, maybe something completly different?
Hm... - 06/17/12 2:49pm
Daniel Yoen says:I've tested it and succeeded in wordpress 3.4
/mybooks/%cat%/%subcat%/%postname%/ | works
/mybooks/%cat%/ | works
In my view. :D - 06/17/12 3:56pm
mark says:hey Daniel,
I just send you an message with the live-example.. it realy doesn't work... :-( and if it would, I would wonder why?
I can't see a function/ section which could do what I've requested... maybe I'm wrong.. but could you please explain how an archive will be displayed by the code posted above? :-)
Thanks
:-)) - 06/20/12 5:31am
mark says:Hey Daniel,
thanks again. The new code works fine for me - no sub-(sub...)-categories, but I can live with that at the moment.
Thanks a lot!
