Show only specific categories in permalinks for custom post type in WordPress
I tried to ask this question in the Wordpress Devlopment network with no success, I'm trying to display only 3 specific categories in permalinks for custom-post-type categories.
Right now the permalinks structure (that is the structure given by the theme i'm using and that i'm modifying through a child theme)is as follows:
www.myfoodblog.com/recipes/the-post-title/
^ ^ ^
root custom-post-type title
some post are under 3 categories that i would like to display in permalinks which are restaurant , users and admin to get something like this
www.myfoodblog.com/recipes/restaurant/the-post-title/
www.myfoodblog.com/recipes/users/the-post-title/
www.myfoodblog.com/recipes/admin/the-post-title/
leaving the original structure for posts that are not in those categories.
I tried using this plugin but it will display the custom post type category for all posts.
I also tried to follow the instructions provided in this question but it's not working, no changes are made in the permalinks structure.
Any advice is much appreciated.
您必须使用post_type_link并添加rewrite rule
function recipes_post_link( $post_link, $id = 0 ){
$post = get_post( $id );
if ( is_object( $post ) ){
$terms = get_the_terms( $post->ID, 'recipe-category' );
foreach($terms as $term) {
if( $term->slug == 'restaurants' || $term->slug == 'users'){
return str_replace( site_url()."/recipes" , site_url()."/recipes/".$term->slug , $post_link );
}
}
}
return $post_link;
}
add_filter( 'post_type_link', 'recipes_post_link', 1, 3 );
function custom_rewrite_basic() {
add_rewrite_rule('^recipes/(.+)/(.+)', 'index.php?recipe=$matches[2]', 'top');
}
add_action('init', 'custom_rewrite_basic');
Create Post Type
add_action( 'init', 'codex_recipes_init' );
/**
* Register a recipes post type.
*
* @link http://codex.wordpress.org/Function_Reference/register_post_type
*/
function codex_recipes_init() {
$labels = array(
'name' => _x( 'Recipes', 'post type general name', 'your-plugin-textdomain' ),
'singular_name' => _x( 'Recipe', 'post type singular name', 'your-plugin-textdomain' ),
'menu_name' => _x( 'Recipes', 'admin menu', 'your-plugin-textdomain' ),
'name_admin_bar' => _x( 'Recipe', 'add new on admin bar', 'your-plugin-textdomain' ),
'add_new' => _x( 'Add New', 'recipe', 'your-plugin-textdomain' ),
'add_new_item' => __( 'Add New Recipe', 'your-plugin-textdomain' ),
'new_item' => __( 'New Recipe', 'your-plugin-textdomain' ),
'edit_item' => __( 'Edit Recipe', 'your-plugin-textdomain' ),
'view_item' => __( 'View Recipe', 'your-plugin-textdomain' ),
'all_items' => __( 'All Recipes', 'your-plugin-textdomain' ),
'search_items' => __( 'Search Recipes', 'your-plugin-textdomain' ),
'parent_item_colon' => __( 'Parent Recipes:', 'your-plugin-textdomain' ),
'not_found' => __( 'No recipes found.', 'your-plugin-textdomain' ),

);
$args = array(
'labels' => $labels,
'description' => __( 'Description.', 'your-plugin-textdomain' ),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => array( 'slug' => 'recipes/%type%' ),
'capability_type' => 'post',
'has_archive' => 'recipes',

'menu_position' => null,
'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )
);
register_post_type( 'recipes', $args );
}
Important: look on rewrite rule: 'rewrite'=> array( 'slug' => 'recipes/%type%' ),
Create Custom Taxonomy
// hook into the init action and call create_recipes_taxonomies when it fires
add_action( 'init', 'create_recipes_taxonomies', 0 );
function create_recipes_taxonomies() {
// Add new taxonomy, NOT hierarchical (like tags)
$labels = array(
'name' => _x( 'Type', 'taxonomy general name', 'textdomain' ),
'singular_name' => _x( 'Type', 'taxonomy singular name', 'textdomain' ),
'search_items' => __( 'Search Types', 'textdomain' ),
'popular_items' => __( 'Popular Types', 'textdomain' ),
'all_items' => __( 'All Types', 'textdomain' ),
'parent_item' => null,
'parent_item_colon' => null,
'edit_item' => __( 'Edit Type', 'textdomain' ),
'update_item' => __( 'Update Type', 'textdomain' ),

'choose_from_most_used' => __( 'Choose from the most used types', 'textdomain' ),
'not_found' => __( 'No types found.', 'textdomain' ),
'menu_name' => __( 'Types', 'textdomain' ),
);
$args = array(
'hierarchical' => true,
'labels' => $labels,
'show_ui' => true,
'show_admin_column' => true,
'update_count_callback' => '_update_post_term_count',
'query_var' => true,
'rewrite' => array( 'slug' => 'type' ),
);
register_taxonomy( 'type', 'recipes', $args );
}
Add Filter Post Type Link
function recipes_post_link( $post_link, $id = 0 ){
$post = get_post( $id );
if ( is_object( $post ) ){
$terms = wp_get_object_terms( $post->ID, 'type' );
if( $terms ){
return str_replace( '%type%' , $terms[0]->slug , $post_link );
}
}
return $post_link;
}
add_filter( 'post_type_link', 'recipes_post_link', 1, 3 );
Important: After all go to permalink options and reset it.
