Woocommerce custom product category dropdown issue

问题:

I am developing a child theme for the Storefront Theme. I use the Product Category Widget as a dropdown under the header which fits my needs perfectly, though I need the same (if possible) dropdown menu to show up on every Category Page, instead of just the Main Page.

I am customizing this code which almost does it:

/**
 * WooCommerce Extra Feature
 * --------------------------
 *
 * Register a shortcode that creates a product categories dropdown list
 *
 * Use: [product_categories_dropdown orderby="title" count="0" hierarchical="0"]
 */
add_shortcode( 'product_categories_dropdown', 'woo_product_categories_dropdown' );
function woo_product_categories_dropdown( $atts ) {
    extract( shortcode_atts(array(
        'count'        => '0',
        'hierarchical' => '0',
        'orderby'      => ''
    ), $atts ) );
    ob_start();
    // Stuck with this until a fix for http://core.trac.wordpress.org/ticket/13258
    wc_product_dropdown_categories( array(
        'orderby'            => ! empty( $orderby ) ? $orderby : 'order',
        'hierarchical'       => $hierarchical,
        'show_uncategorized' => 0,
        'show_counts'        => $count
    ) );
    ?>
    <script type='text/javascript'>
        /* <![CDATA[ */
        jQuery(function(){
            var product_cat_dropdown = jQuery(".dropdown_product_cat");
            function onProductCatChange() {
                if ( product_cat_dropdown.val() !=='' ) {
                    location.href = "<?php echo esc_url( home_url() ); ?>/?product_cat=" +product_cat_dropdown.val();
                }
            }
            product_cat_dropdown.change( onProductCatChange );
        });
    /* ]]> */
    </script>
    <?php
    return ob_get_clean();
}

Now I need to hide the counters and show the empty Categories.

I haven't be able to get that.

How can I hide the counters and show the empty Categories?

回答1:

In your code there was:

• some mistakes in the code like wrong 'show_counts' that is 'show_count' (without s) … Now hiding counters is enabled and functional.
• missing argument 'hide_empty' to show empty categories

In this shortcode you can alter the following optional arguments:

• hierarchical that is disabled by default (set to '0')
• hide_empty that is disabled by default (set to '0')
• show_count that is now disabled by default (set to '0')
• depth that is disabled by default (set to '0')
• orderby set to category "order" by default (can be by names too: "name")

Added a custom hook woocommerce_product_categories_shortcode_dropdown_args that will allow extended customizations…

Here is the new code:

add_shortcode( 'product_categories_dropdown', 'woo_product_categories_dropdown' );
function woo_product_categories_dropdown( $atts ) {
    // Attributes
    $atts = shortcode_atts( array(
        'hierarchical' => '0', // or '1'
        'hide_empty'   => '0', // or '1'
        'show_count'   => '0', // or '1'
        'depth'        => '0', // or Any integer number to define depth
        'orderby'      => 'order', // or 'name'
    ), $atts, 'product_categories_dropdown' );

    ob_start();

    wc_product_dropdown_categories( apply_filters( 'woocommerce_product_categories_shortcode_dropdown_args', array(
        'depth'              => $atts['depth'],
        'hierarchical'       => $atts['hierarchical'],
        'hide_empty'         => $atts['hide_empty'],
        'orderby'            => $atts['orderby'],
        'show_uncategorized' => 0,
        'show_count'         => $atts['show_count'],
    ) ) );

    ?>
    <script type='text/javascript'>
        jQuery(function($){
            var product_cat_dropdown = $(".dropdown_product_cat");
            function onProductCatChange() {
                if ( product_cat_dropdown.val() !=='' ) {
                    location.href = "<?php echo esc_url( home_url() ); ?>/?product_cat=" +product_cat_dropdown.val();
                }
            }
            product_cat_dropdown.change( onProductCatChange );
        });
    </script>
    <?php

    return ob_get_clean();
}

Code goes in function.php file of the active child theme (or active theme).

Tested and works.

---

1) Example usage - All product categories and subcategories hierarchically displayed:

[product_categories_dropdown orderby='name' hierarchical='1']

In php code you can use it this way:

echo do_shortcode("[product_categories_dropdown orderby='name' hierarchical='1']");

or inserted in html tags:

<?php echo do_shortcode("[product_categories_dropdown orderby='name' hierarchical='1']"); ?>

---

2) Example usage - Only "main parent" product categories:

[product_categories_dropdown depth='1' hierarchical='1']

In php code you can use it this way:

echo do_shortcode("[product_categories_dropdown depth='1' hierarchical='1']");

or inserted in html tags:

<?php echo do_shortcode("[product_categories_dropdown depth='1' hierarchical='1']"); ?>
