Convert a Woocommerce hooked function into a shortcode

问题

A previous question of mine was answered and included two separate functions, one using a WooCommerce add_action hook. How can I take this answer and convert it to a shortcode that I could add to a product page?

I am using a page builder (Divi Builder) to create a custom layout/template of WooCommerce product pages. Having a shortcode will allow me to paste the shortcode into the builder, and have it output the result anywhere within that template structure.

This is the code I need turned into a shortcode:

// Utility funtion: getting and formtting product data
function format_product_data_output( $the_id ){
    $empty =  __( '<em>(empty)</em>', 'woocommerce' );

    // Get an instance of the WC_Product_Variation object
    $product = wc_get_product( $the_id );

    // Only wc_get_price_to_display() respect if product is to be displayed with or without including taxes
    $price = wc_price( wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) ) );
    $sale_price = wc_get_price_to_display( $product, array( 'price' => $product->get_sale_price() ) );
    $sale_price = ! empty( $sale_price ) ? wc_price($sale_price) : $empty;

    $size = $product->get_attribute( 'pa_size' );
    $size = ! empty( $size ) ? get_term_by( 'slug', $size, 'pa_size' )->name : $empty;

    $stock_qty = $product->get_stock_quantity();
    $stock_qty = ! empty( $stock_qty ) ? $stock_qty : $empty;

    $output = '
    <ul>
        <li class="fs-data-price">'.$price.'</li>
        <li class="fs-data-size">Size: '.$size.'</li>
        <li class="fs-data-sale">'.$sale_price.' Preferred Customer Price</li>
        <li class="fs-data-stock">Quantity in Stock: '.$stock_qty.'</li>
    </ul>';

    return $output;
}

//
add_action( 'woocommerce_after_single_product', 'custom_table_after_single_product' );
function custom_table_after_single_product(){
    global $product;

    $output = '<div class="fs-product-data-wrapper">';

    // Variable products
    if( $product->is_type('variable'))
    {
        // Get available variations in the variable product
        $available_variations = $product->get_available_variations();

        if( count($available_variations) > 0 ){
            foreach( $available_variations as $variation )
                $output .= format_product_data_output( $variation['variation_id'] );
        }
    }
    // Simple products
    elseif( $product->is_type('simple'))
    {
        $output .= format_product_data_output( $product->get_id() );
    }
    else return; // Exit

    echo $output .= '</div>'; // Display
}

Update 2: Try the following:

add_shortcode("variation_table", "custom_available_variations_table");
function custom_available_variations_table( $atts ) {

    global $post;

    // Attributes
    $atts = shortcode_atts(
        array(
            'id'    => $post->ID
        ),
        $atts, 'variation_table'
    );

    if( is_admin() ) return; // Only on front end

    $product = wc_get_product($atts['id']); // Get the WC_Product Object

    $output = '<div class="fs-product-data-wrapper">';

    // Variable products
    if( $product->is_type('variable'))
    {
        // Get available variations in the variable product
        $available_variations = $product->get_available_variations();

        if( count($available_variations) > 0 ){
            foreach( $available_variations as $variation )
                $output .= format_product_data_output( $variation['variation_id'] );
        }
    }
    // Simple products
    elseif( $product->is_type('simple'))
    {
        $output .= format_product_data_output( $product->get_id() );
    }
    else return; // Exit

    return $output .= '</div>'; // return always for a shortcode
}

// Utility funtion: getting and formtting product data
function format_product_data_output( $the_id ){
    $empty =  __( '<em>(empty)</em>', 'woocommerce' );

    // Get an instance of the WC_Product_Variation object
    $product = wc_get_product( $the_id );

    // Only wc_get_price_to_display() respect if product is to be displayed with or without including taxes
    $price = wc_price( wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) ) );
    $sale_price = wc_get_price_to_display( $product, array( 'price' => $product->get_sale_price() ) );
    $sale_price = ! empty( $sale_price ) ? wc_price($sale_price) : $empty;

    $size = $product->get_attribute( 'pa_size' );
    $size = ! empty( $size ) ? get_term_by( 'slug', $size, 'pa_size' )->name : $empty;

    $stock_qty = $product->get_stock_quantity();
    $stock_qty = ! empty( $stock_qty ) ? $stock_qty : $empty;

    $output = '
    <ul>
        <li class="fs-data-price">'.$price.'</li>
        <li class="fs-data-size">Size: '.$size.'</li>
        <li class="fs-data-sale">'.$sale_price.' Preferred Customer Price</li>
        <li class="fs-data-stock">Quantity in Stock: '.$stock_qty.'</li>
    </ul>';

    return $output;
}

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

SHORTCODE USAGE:

In a product page: [variation_table] (without any need of define an ID)
Anywhere defining the product ID: [variation_table id='27']

You will need to use Wordpress Shortcode Api

Implementation would be something like this:

 function format_product_data_output( $the_id ){
        $empty =  __( '<em>(empty)</em>', 'woocommerce' );

        // Get an instance of the WC_Product_Variation object
        $product = wc_get_product( $the_id );

        // Only wc_get_price_to_display() respect if product is to be displayed with or without including taxes
        $price = wc_price( wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) ) );
        $sale_price = wc_get_price_to_display( $product, array( 'price' => $product->get_sale_price() ) );
        $sale_price = ! empty( $sale_price ) ? wc_price($sale_price) : $empty;

        $size = $product->get_attribute( 'pa_size' );
        $size = ! empty( $size ) ? get_term_by( 'slug', $size, 'pa_size' )->name : $empty;

        $stock_qty = $product->get_stock_quantity();
        $stock_qty = ! empty( $stock_qty ) ? $stock_qty : $empty;

        $output = '
        <ul>
            <li class="fs-data-price">'.$price.'</li>
            <li class="fs-data-size">Size: '.$size.'</li>
            <li class="fs-data-sale">'.$sale_price.' Preferred Customer Price</li>
            <li class="fs-data-stock">Quantity in Stock: '.$stock_qty.'</li>
        </ul>';

        return $output;
    }

add_shortcode( 'format', 'format_product_data_output' );

I have added the add_shortcode line,

The explanation is that the shortcode 'format' does the 'format_product_data_output' function.
