WooCommerce - filter by featured products in admin

Question

WooCommerce has a simple way to pick "Featured" products by clicking a little star icon in the "Featured" column in the admin area.

I need to be able to filter and show only featured products in the admin area. Does anyone know of a straightforward way to do this?

I did some digging and it turns out this is done with meta key/values, where _featured is the key and the value is either yes or no.

Unfortunately, since it's not done with taxonomies like product categories, there is no way to use the filter functionality in the admin area to show only featured products. You can sort the featured column so they are all either at the top of bottom of the product list, but that's it.

Answer 1

I found this plugin: https://wordpress.stackexchange.com/a/45447/15190, which I was able to customize to provide a select list to filter by Featured product. With that, I am able to then use WooCommerce's Sort Products drag and drop feature to easily change the order that Featured products appear in the Featured Products widget and other places.

Here is the code with my customizations that will make it work for WooCommerce Featured Products:

<?php
/*

Plugin URI: http://en.bainternet.info
Description: adapted from https://wordpress.stackexchange.com/q/45436/2487. Allows you to show only Featured products, which will then allow for drag and drop sorting of Featured products

/**

function wpse45436_admin_posts_filter_restrict_manage_posts(){
    $type = 'post';
    if (isset($_GET['post_type'])) {
        $type = $_GET['post_type'];
    }

    //only add filter to post type you want
    if ('product' == $type){
        //change this to the list of values you want to show
        //in 'label' => 'value' format
        $values = array(
            'Show Only Featured' => 'Yes', 
            'Show Only Non-Featured' => 'No',
        );
        ?>
        <select name="Featured">
        <option value=""><?php _e('Show Featured & Non-Featured', 'wpse45436'); ?></option>
        <?php
            $current_v = isset($_GET['Featured'])? $_GET['Featured']:'';
            foreach ($values as $label => $value) {
                printf
                    (
                        '<option value="%s"%s>%s</option>',
                        $value,
                        $value == $current_v? ' selected="selected"':'',
                        $label
                    );
                }
        ?>
        </select>
        <?php
    }
}

add_filter( 'parse_query', 'wpse45436_posts_filter' );
/**

 *

 */
function wpse45436_posts_filter( $query ){
    global $pagenow;
    $type = 'post';
    if (isset($_GET['post_type'])) {
        $type = $_GET['post_type'];
    }
    if ( 'product' == $type && is_admin() && $pagenow=='edit.php' && isset($_GET['Featured']) && $_GET['Featured'] != '') {
        $query->query_vars['meta_key'] = '_featured';
        $query->query_vars['meta_value'] = $_GET['Featured'];
    }
}

Answer 2

You can sort your products list by the featured status. Just click on the star at the top of the column.... once will put all non-featured items at the top, and twice should reverse this and put all featured items at the top.

Your admin url will look like: /wp-admin/edit.php?post_type=product&orderby=featured&order=desc

EDIT:

Ok, so it turned out to not be that hard to filter by featured status. WooCommerce is filtering by "subtype", and since that is also filtering by meta, we can mostly just copy their code and make a few adjustments.

The first function adds the select/drop-down element, while the second handles the adjustments to the admin query.

/**
 * Filter products by type
 *
 * @access public
 * @return void
 */
function wpa104537_filter_products_by_featured_status() {

     global $typenow, $wp_query;

    if ($typenow=='product') :


        // Featured/ Not Featured
        $output .= "<select name='featured_status' id='dropdown_featured_status'>";
        $output .= '<option value="">'.__( 'Show All Featured Statuses', 'woocommerce' ).'</option>';

        $output .="<option value='featured' ";
        if ( isset( $_GET['featured_status'] ) ) $output .= selected('featured', $_GET['featured_status'], false);
        $output .=">".__( 'Featured', 'woocommerce' )."</option>";

        $output .="<option value='normal' ";
        if ( isset( $_GET['featured_status'] ) ) $output .= selected('normal', $_GET['featured_status'], false);
        $output .=">".__( 'Not Featured', 'woocommerce' )."</option>";

        $output .="</select>";

        echo $output;
    endif;
}

add_action('restrict_manage_posts', 'wpa104537_filter_products_by_featured_status');

/**
 * Filter the products in admin based on options
 *
 * @access public
 * @param mixed $query
 * @return void
 */
function wpa104537_featured_products_admin_filter_query( $query ) {
    global $typenow, $wp_query;

    if ( $typenow == 'product' ) {

        // Subtypes
        if ( ! empty( $_GET['featured_status'] ) ) {
            if ( $_GET['featured_status'] == 'featured' ) {
                $query->query_vars['meta_value']    = 'yes';
                $query->query_vars['meta_key']      = '_featured';
            } elseif ( $_GET['featured_status'] == 'normal' ) {
                $query->query_vars['meta_value']    = 'no';
                $query->query_vars['meta_key']      = '_featured';
            }
        }

    }

}

add_filter( 'parse_query', 'wpa104537_featured_products_admin_filter_query' );

Updated for WooCommerce 3.0

The parse_query callback must be updated as the featured status is no longer stored as post meta.

/**
 * Filter the products in admin based on options
 *
 * @access public
 * @param mixed $query
 * @return void
 */
function wpa104537_featured_products_admin_filter_query( $query ) {
    global $typenow;

    if ( $typenow == 'product' ) {

        // Subtypes
        if ( ! empty( $_GET['featured_status'] ) ) {
            if ( $_GET['featured_status'] == 'featured' ) {
                $query->query_vars['tax_query'][] = array(
                    'taxonomy' => 'product_visibility',
                    'field'    => 'slug',
                    'terms'    => 'featured',
                );
            } elseif ( $_GET['featured_status'] == 'normal' ) {
                $query->query_vars['tax_query'][] = array(
                    'taxonomy' => 'product_visibility',
                    'field'    => 'slug',
                    'terms'    => 'featured',
                    'operator' => 'NOT IN',
                );
            }
        }

    }

}
add_filter( 'parse_query', 'wpa104537_featured_products_admin_filter_query' );
