Question

我创建了四个短代码段来显示woocommerce产品总数，以及我的三个父类别中每个类别的产品数。

它们起作用了，但是有一种方法可以将4个片段（总计，苹果，橘子，梨）组合成一个片段，从而允许简码中的变量表示要显示的产品数量？

// [title-total] shortcode
function total_product_count_shortcode( ) {
    $count_posts = wp_count_posts( 'product' );
    return esc_html($count_posts->publish);
}
add_shortcode( 'title-total', 'total_product_count_shortcode' );

// [title-apples] shortcode
add_shortcode( 'title-apples', function() {
$query = new WP_Query( array(
    'tax_query' => array(
        array(
            'taxonomy' => 'product_cat',
            'field' => 'id',
            'terms' => 254, // Replace with the parent category ID
            'include_children' => true,
        ),
    ),
    'nopaging' => true,
    'fields' => 'ids',
) );

return esc_html( $query->post_count );
} );

// [title-oranges] shortcode
add_shortcode( 'title-oranges', function() {
$query = new WP_Query( array(
    'tax_query' => array(
        array(
            'taxonomy' => 'product_cat',
            'field' => 'id',
            'terms' => 256, // Replace with the parent category ID
            'include_children' => true,
        ),
    ),
    'nopaging' => true,
    'fields' => 'ids',
) );

return esc_html( $query->post_count );
} );

// [title-pears] shortcode
add_shortcode( 'title-pears', function() {
$query = new WP_Query( array(
    'tax_query' => array(
        array(
            'taxonomy' => 'product_cat',
            'field' => 'id',
            'terms' => 214, // Replace with the parent category ID
            'include_children' => true,
        ),
    ),
    'nopaging' => true,
    'fields' => 'ids',
) );

return esc_html( $query->post_count );
} );

是可能的。由于您的最后三个简码非常相似（只是'terms'值的变化），我们可以将其合并为一个…然后下面的代码会将您的4个简码嵌入其中：

function custom_multi_shortcode( $atts, $content = null ) {
    // Shortcode attributes
    $atts = shortcode_atts(
        array( 'term' => '' ),
        $atts, 'cmulti'
    );

    // 1 - Total product count
    if ( empty($atts['term']) ):    
        $count_posts = wp_count_posts( 'product' );
        return esc_html($count_posts->publish);

    // 2 to 4 - Apples, Oranges and Pears
    else:
        $query = new WP_Query( array(
            'tax_query' => array(
                array(
                    'taxonomy' => 'product_cat',
                    'field' => 'id',
                    'terms' => (int) $atts['term'], // Replace with the parent category ID
                    'include_children' => true,
                ),
            ),
            'nopaging' => true,
            'fields' => 'ids',
        ) );
        return esc_html( $query->post_count );
    endif;
}
add_shortcode( 'cmulti', 'custom_multi_shortcode' );

代码进入您的活动子主题（或活动主题）的function.php文件中。经过测试，可以正常工作。

用法（针对每个方法）：

产品总数：[cmulti]
苹果：[cmulti term='254']
橙色：[cmulti term='256']
梨：[cmulti term='214']

组合Wordpress多个短代码
