category page for custom post type

Question

I know this question has been asked a thousand times, but feel like I've looked at every single article on this issue, and none of them have worked for me.

All I want is for there to be a category page for my custom post type, products. So that I can type www.mysite.com/products and see all the products. Or if it's easier make it work like regular posts do www.mysite.com/category/products. Either works for me.

I have written the code in functions.php and also used plugins like CPT-onomy and CPT-UI to successfully make the custom post types and taxonomies. But this doesn't create the category page.

How is this accomplished? Please include instructions on permalinks if that is relevant to my situation too.

Here is the code I placed in functions.php. The second block that deals with taxonomies actually breaks the site. However, using the two plugins mentioned above, I've been able to successfully create taxonomies, but still can't get a category page.

add_action( 'init', 'create_post_type' );
function create_post_type() {
    register_post_type( 'product',
        array(
            'labels' => array(
                'name' => __( 'Products' ),
                'singular_name' => __( 'Product' )
            ),
        'public' => true,
        'has_archive' => true,
        'exclude_from_search' => false,
        'show_ui' => true,
        'supports' => array('title', 'editor', 'thumbnail', 'custom-fields'),
        'taxonomies' => array('category', 'post_tag')
        )
    );
}


function my_taxonomies_product() {
    $args = array();
    register_taxonomy( 'product_category', 'product' $args );
}

add_action( 'init', 'my_taxonomies_product', 0 );

updated code

function create_post_type() {
    register_post_type( 'product',
        array(
            'labels' => array(
                'name' => __( 'Products' ),
                'singular_name' => __( 'Product' )
            ),
        'public' => true,
        'has_archive' => true,
        'exclude_from_search' => true,
        'show_ui' => true,
        'supports' => array('title', 'editor', 'thumbnail', 'custom-fields'),
        )
    );
}
add_action( 'init', 'create_post_type' );

function my_taxonomies_product() {
    $labels = array(
        'name'              => _x( 'Product Categories', 'taxonomy general name' ),
        'singular_name'     => _x( 'Product Category', 'taxonomy singular name' ),
        'search_items'      => __( 'Search Product Categories' ),
        'all_items'         => __( 'All Product Categories' ),
        'parent_item'       => __( 'Parent Product Category' ),
        'parent_item_colon' => __( 'Parent Product Category:' ),
        'edit_item'         => __( 'Edit Product Category' ), 
        'update_item'       => __( 'Update Product Category' ),
        'add_new_item'      => __( 'Add New Product Category' ),
        'new_item_name'     => __( 'New Product Category' ),
        'menu_name'         => __( 'Product Categories' ),
    );
    $rewrite = array(
        'slug' => 'type',
        'with_front' => true,
        'hierarchical' => true,
    );
    $args = array(
        'labels' => $labels,
        'hierarchical' => true,
        'rewrite' => $rewrite,
    );
    register_taxonomy( 'product_category', 'product', $args );
}
add_action( 'init', 'my_taxonomies_product', 0 );

Answer 1

First, your taxonomy code has a missing comma before $args which is causing a fatal error:

register_taxonomy( 'product_category', 'product', $args );

Enable debugging while working on code to see PHP errors, which would reveal the line number and error.

As for your post type, you have a page where you can view all products, which is the post type archive. This argument in your post type registration code enables that:

'has_archive' => true

But since you've only set it to true, it will use the post type name as the archive slug, so your archive is located at:

mysite.com/product/

To change that, simply set it to the slug you want to use:

'has_archive' => 'products'

Then your archive will be located where you want it:

mysite.com/products/

Remember to visit your Settings > Permalinks page after making changes that effect permalinks, this will flush the rewrite rules.

Answer 2

If you use custom taxonomy post type, you can create taxonomy-your-taxonomy-post-type.php.

Let's say for your url www.mysite.com/products, your must create taxonomy-products.php

Answer 3

Step:1 First of all add custom post type News with Taxonomy category_news.

function news() {
        $args = array(
            'label' => 'News',
            'singular_label' => 'news',
            'public' => true,
            'show_ui' => true,
            'capability_type' => 'post',
            'hierarchical' => false,
            'rewrite' => true,
            'menu_icon' => 'dashicons-calendar',
            'supports' => array('title','editor','thumbnail')
        );
        register_post_type('news',$args);

    }
add_action('init', 'news');
register_taxonomy('category_news', array('news'), array('hierarchical' => true, 'label' => 'News category','show_admin_column' => true, 'singular_label' => 'News category', 'rewrite' => true));

Step:2 Add template of category page using taxonomy-{taxonomy}.php... In our example it should be taxonomy-category_news.php
