根据分配的分类术语按商店经理过滤 WooCommerce 订单

Filter WooCommerce orders by shop manager based on assigned taxonomy terms

我想将带有特定产品标签的订单分配给后端的特定商店经理,并隐藏其余订单。

我目前正在使用 Order Splitter for WooCommerce 免费插件将订单按项目(产品)拆分为单独的订单。

我遇到了这个使用产品类型过滤订单的非常好的解决方案: 我试图对其进行编辑以仅显示特定的产品标签,然而,没有运气。我做错了什么?

产品标签名为“brand1”,店长帐号 ID 为 7。

add_action( 'restrict_manage_posts', 'admin_shop_order_by_product_type_filter' );    
function admin_shop_order_by_product_type_filter(){
    global $pagenow, $post_type;
    $whoisin = get_current_user_id();
    if( 'shop_order' === $post_type && 'edit.php' === $pagenow && ($whoisin == 7) ) {
        $domain     = 'woocommerce';
        $filter_id  = 'brand1';
        $current    = isset($_GET[$filter_id])? $_GET[$filter_id] : '';
        $query_args = ['taxonomy' => 'product_tag', 'fields' => 'names', 'orderby' => 'order'];



        echo '<select name="'.$filter_id.'">
        <option value="">' . __('Filter by Product Tag', $domain) . '</option>';

        foreach ( get_terms($query_args) as $term_name ) {
            printf( '<option value="%s"%s>%s</option>', $term_name,
                $term_name === $current ? '" selected="selected"' : '', ucfirst($term_name) );
        }
        echo '</select>';
    }
} 


add_action( 'pre_get_posts','process_admin_shop_order_product_type_filter' );
function process_admin_shop_order_product_type_filter( $query ) { 
    global $pagenow, $post_type, $wpdb;

    $filter_id = 'brand1';
    $whoisin = get_current_user_id();

    if ( $query->is_admin && 'edit.php' === $pagenow && 'shop_order' === $post_type
         && isset( $_GET[$filter_id] ) && $_GET[$filter_id] != '' && ($whoisin == 7)) {

        $order_ids = $wpdb->get_col( "
            SELECT DISTINCT o.ID
            FROM {$wpdb->prefix}posts o
            INNER JOIN {$wpdb->prefix}woocommerce_order_items oi
                ON oi.order_id = o.ID
            INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta oim
                ON oi.order_item_id = oim.order_item_id
            INNER JOIN {$wpdb->prefix}term_relationships tr
                ON oim.meta_value = tr.object_id
            INNER JOIN {$wpdb->prefix}term_taxonomy tt
                ON tr.term_taxonomy_id = tt.term_taxonomy_id
            INNER JOIN {$wpdb->prefix}terms t
                ON tt.term_id = t.term_id
            WHERE o.post_type = '$post_type'
            AND oim.meta_key = '_product_id'
            AND tt.taxonomy = 'product_tag'
            AND t.name = '{$_GET[$filter_id]}'
        ");

        $query->set( 'post__in', $order_ids ); // Set the new "meta query"

        $query->set( 'posts_per_page', 25 ); // Set "posts per page"

        $query->set( 'paged', ( get_query_var('paged') ? get_query_var('paged') : 1 ) ); // Set "paged"
    }                                                                                           
}

以下更改后的代码将根据分配给商店经理(用户 ID)的相关产品标签显示订单。

在第一个函数中,您将通过商店经理(用户 ID)分配产品标签。然后,每个商店经理的订单将被不同地过滤,只显示他们分配的订单。只有定义的用户 ID 才会过滤订单。

代码:

// Settings function
function orders_by_shop_manager_settings(){// Your settings below
    // Your settings below
    return array(
        // Terms field type (can be 'name', 'slug' or 'term_id')
        'field'     => 'slug',
        // The taxonomy for product tags (brands)
        'taxonomy'  => 'product_tag',
        // Manager ID / product tags terms pairs (set the correct term field type as defined before)
        'assignments' => array(
            '7'     => array('brand1','brand7', 'brand9'),
            '12'    => array('brand3','brand5', 'brand6', 'brand8'),
            '189'   => array('brand2','brand4'),
        )
    );
}

// Filtering orders by shop manager based on items product tag(s)
add_action( 'pre_get_posts','filter_orders_by_shop_manager' );
function filter_orders_by_shop_manager( $query ) {
    global $pagenow, $typenow, $wpdb;

    if ( $query->is_admin && 'edit.php' === $pagenow && 'shop_order' === $typenow ) {
        // Loading settings data
        $data    = orders_by_shop_manager_settings();
        $user_id = get_current_user_id();
    }

    if( isset($data) && isset($data['assignments'][$user_id]) ) {
        $taxonomy   = $data['taxonomy'];
        $field      = $data['field'];
        $terms      = $data['assignments'][$user_id];

        $order_ids = $wpdb->get_col( "
            SELECT DISTINCT o.ID
            FROM {$wpdb->prefix}posts o
            INNER JOIN {$wpdb->prefix}woocommerce_order_items oi
                ON oi.order_id = o.ID
            INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta oim
                ON oi.order_item_id = oim.order_item_id
            INNER JOIN {$wpdb->prefix}term_relationships tr
                ON oim.meta_value = tr.object_id
            INNER JOIN {$wpdb->prefix}term_taxonomy tt
                ON tr.term_taxonomy_id = tt.term_taxonomy_id
            INNER JOIN {$wpdb->prefix}terms t
                ON tt.term_id = t.term_id
            WHERE o.post_type = '$typenow'
            AND oim.meta_key IN ( '_product_id','_variation_id' )
            AND tt.taxonomy = '$taxonomy'
            AND t.$field IN ( '" . implode( "','", $terms ) . "' )
        ");

        if ( count($order_ids) > 0 ) {
            $query->set( 'post__in', $order_ids ); // Set the new "meta query"
            $query->set( 'posts_per_page', 25 );
        } else {
            $query->set( 'author__in', 99999999 );
        }
    }
}
