    Hi, I’ve been trying to call a single product’s attributes via shortcode and use in my page builder. The code is below; 

    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 );

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

    $output = '
    <ul>
        <li class="fs-data-size">Durability: '.$durability.'</li>

    </ul>';

    return $output;
}

    And below is the error I keep getting

    Uncaught Error: Call to a member function get_type() on bool in wp-content/themes/childtheme/functions.php:139

  • This means your $product variable is empty. And get_type() expects the product object. Check in your code why the $product variable does not contain the product object.

    Sometimes you can’t get the product type globally… as it depends on the WC_Product object.

    1) From a dynamic product id variable (when you doesn’t have the $product object:

    $product = wc_get_product( $product_id );
    or

    $product = wc_get_product( get_the_id() );
    2) From $product global variable on single product pages (and on product archive pages inside the loop):

    global $product;

    // Check that WC_Product instance $product variable is defined and accessible

    if ( ! is_a( $product, 'WC_Product' ) ) {
    $product = wc_get_product( get_the_id() );
3) In cart items:

    // Loop throught cart items

    foreach( WC()->cart->get_cart() as $cart_item ){
    $product = $cart_item['data'];
}

    3) In order items:

    // Loop through order items

    foreach ( $order->get_items() as $item ) {
    $product = $item->get_product();
}

    Problem was due to specifying the product type with is_type condition, which I don’t really need. I removed those conditions and I seems to be working
