I've tried so many different thing, and read 30 different posts and I just can't get the custom rewrite to work with a custom post_type and custom taxonomy.
Here's my code:
function product_register() {
$labels = array(
'name' => __('My Products', 'post type general name'),
'singular_name' => __('Product', 'post type singular name'),
'add_new' => __('Add New', 'Product'),
'add_new_item' => __('Add New Product'),
'edit_item' => __('Edit Product'),
'new_item' => __('New Product'),
'view_item' => __('View This Product'),
'search_items' => __('Search Products'),
'not_found' => __('Nothing found'),
'not_found_in_trash' => __('Nothing found in Trash'),
'parent_item_colon' => ''
);
$args = array(
'labels' =>$labels,
'public' => true,
'publicly_queryable' =>true,
'show_ui' =>true,
'query_var' => true,
'menu_icon' => plugin_dir_url( __FILE__ ).'/icon.png',
'rewrite' => array( 'slug' => 'products/%taxonomy_name%', 'with_front' => false,'hierarchical' => true),
'capability_type' => 'post',
'hierarchical' >= false,
'menu_position' => null,
'supports' => array('title','editor','thumbnail','revisions')
);
register_post_type( 'products' , $args );
}
function create_product_taxonomies() {
$labels = array(
'name' => _x( 'Categories', 'taxonomy general name' ),
'singular_name' => _x( 'Category', 'taxonomy singular name' ),
'search_items' => __( 'Search Categories' ),
'all_items' => __( 'All Categories' ),
'parent_item' => __( 'Parent Category' ),
'parent_item_colon' => __( 'Parent Category:' ),
'edit_item' => __( 'Edit Category' ),
'update_item' => __( 'Update Category' ),
'add_new_item' => __( 'Add New Category' ),
'new_item_name' => __( 'New Category Name' ),
'menu_name' => __( 'Categories' ),
);
$rewrite = array(
'slug' => 'products',
'with_front' => false,
'hierarchical' => true
);
$args = array(
'hierarchical' => true,
'labels' => $labels,
'show_ui' => true,
'show_admin_column' => true,
'query_var' => true,
'rewrite' => $rewrite, // this makes hierarchical URLs
);
register_taxonomy( 'product_category', array( 'products' ), $args );
$labels = array(
'name' => _x( 'Sales', 'taxonomy general name' ),
'singular_name' => _x( 'Sale', 'taxonomy singular name' ),
'search_items' => __( 'Search Sales' ),
'all_items' => __( 'All Sales' ),
'parent_item' => __( 'Parent Sale' ),
'parent_item_colon' => __( 'Parent Sale:' ),
'edit_item' => __( 'Edit Sale' ),
'update_item' => __( 'Update Sale' ),
'add_new_item' => __( 'Add New Sale' ),
'new_item_name' => __( 'New Sale Name' ),
'menu_name' => __( 'Sale' ),
);
$args = array(
'hierarchical' => true,
'labels' => $labels,
'show_ui' => true,
'show_admin_column' => true,
'query_var' => true,
'rewrite' => array( 'slug' => 'product_sale', 'hierarchical' =>true ),
);
register_taxonomy( 'product_sale', array( 'products' ), $args );
}
function add_rules(){
add_rewrite_rule( '^products/(.+?)/(.+?)/$', 'products.php?posttype=$matches[2]', 'top' );
add_rewrite_rule( '^products/(.+?)/(.+?)/(.+?)$', 'products.php?taxonomy=$matches[3]', 'top' );
add_rewrite_rule( '^products/(.+?)/(.+?)/?$', 'products.php?taxonomy=$matches[2]', 'top' );
add_rewrite_rule( '^products/(.+?)/(.+?)/(.+?)/(.+?)$', 'products.php?taxonomy=$matches[3]&products=$matches[4]', 'top' );
}
/* Register products taxonomies */
add_action('init', 'create_product_taxonomies', 0 );
/* Register custom post types on the 'init' hook. */
add_action('init', 'product_register');
function filter_post_type_link($link, $post)
{
if ($post->post_type != 'products')
return $link;
if ($cats = get_the_terms($post->ID, 'product_category'))
{
$replace = get_taxonomy_parents(array_pop($cats)->term_id, 'product_category', false, '/', true);
$link = str_replace('%taxonomy_name%', rtrim($replace, '/'), $link); // see custom function defined below
}
return $link;
}
add_filter('post_type_link', 'filter_post_type_link', 10, 2);
// my own function to do what get_category_parents does for other taxonomies
function get_taxonomy_parents($id, $taxonomy, $link = false, $separator = '/', $nicename = false, $visited = array()) {
$chain = '';
$parent = &get_term($id, $taxonomy);
if (is_wp_error($parent)) {
return $parent;
}
if ($nicename)
$name = $parent -> slug;
else
$name = $parent -> name;
if ($parent -> parent && ($parent -> parent != $parent -> term_id) && !in_array($parent -> parent, $visited)) {
$visited[] = $parent -> parent;
$chain .= get_taxonomy_parents($parent -> parent, $taxonomy, $link, $separator, $nicename, $visited);
}
if ($link) {
// nothing, can't get this working :(
} else
$chain .= $name . $separator;
return $chain;
}
So, when I go to example.com/cat_1/cat_2/cat_3, it all works. It shows the proper category. When I add the actual product on the end, it gives me a error 404. I should also note that even though the rewrite is for products.php, I actually have to use taxonomy.php for it to show up.
Am I missing some configuration details somewhere?
DUH! Answered my question, and now I'm beating my head against the wall really hard.... Changed:
add_rewrite_rule( '^products/(.+?)/(.+?)/(.+?)/(.+?)$', 'products.php?taxonomy=$matches[3]&products=$matches[4]', 'top' );
To:
add_rewrite_rule( '^products/(.+?)/(.+?)/(.+?)/(.+?)$', 'index.php?taxonomy=$matches[3]&products=$matches[4]', 'top' );
Need to use index.php to show the post details. Man alive....
