I need to add my own price table before the description of a variation product in woocommerce. I did that by customizing the get_available_variation function of class-wc-product-variable.php, which is in the includes directory of woocommerce.

I don't want to override this plugin, as the changes will get lost after an update.

How do I modify this function without hacking woocommerce?

public function get_available_variation( $variation ) {



    if ( is_numeric( $variation ) ) {

        $variation = wc_get_product( $variation );

    }

    if ( ! $variation instanceof WC_Product_Variation ) {

        return false;

    }

    // See if prices should be shown for each variation after selection.

    $show_variation_price = apply_filters( 'woocommerce_show_variation_price', $variation->get_price() === '' || $this->get_variation_sale_price( 'min' ) !== $this->get_variation_sale_price( 'max' ) || $this->get_variation_regular_price( 'min' ) !== $this->get_variation_regular_price( 'max' ), $this, $variation );



    return apply_filters(

        'woocommerce_available_variation', array(

            'attributes'            => $variation->get_variation_attributes(),

            'availability_html'     => wc_get_stock_html( $variation ),

            'backorders_allowed'    => $variation->backorders_allowed(),

            'dimensions'            => $variation->get_dimensions( false ),

            'dimensions_html'       => wc_format_dimensions( $variation->get_dimensions( false ) ),

            'display_price'         => wc_get_price_to_display( $variation ),

            'display_regular_price' => wc_get_price_to_display( $variation, array( 'price' => $variation->get_regular_price() ) ),

            'image'                 => wc_get_product_attachment_props( $variation->get_image_id() ),

            'image_id'              => $variation->get_image_id(),

            'is_downloadable'       => $variation->is_downloadable(),

            'is_in_stock'           => $variation->is_in_stock(),

            'is_purchasable'        => $variation->is_purchasable(),

            'is_sold_individually'  => $variation->is_sold_individually() ? 'yes' : 'no',

            'is_virtual'            => $variation->is_virtual(),

            'max_qty'               => 0 < $variation->get_max_purchase_quantity() ? $variation->get_max_purchase_quantity() : '',

            'min_qty'               => $variation->get_min_purchase_quantity(),

            'price_html'            => $show_variation_price ? '<span class="price">' . $variation->get_price_html() . '</span>' : '',

            'sku'                   => $variation->get_sku(),

            'variation_description' => CUSTOM_PRICE_TABLE($variation) . wc_format_content( $variation->get_description() ),

            'variation_id'          => $variation->get_id(),

            'variation_is_active'   => $variation->variation_is_active(),

            'variation_is_visible'  => $variation->variation_is_visible(),

            'weight'                => $variation->get_weight(),

            'weight_html'           => wc_format_weight( $variation->get_weight() ),

        ), $this, $variation

    );

}

The only change I have to make is adding 'CUSTOM_PRICE_TABLE ($ Variation)' to the variation description.

You just need to use woocommerce_available_variation filter hook this way:

add_filter( 'woocommerce_available_variation', 'form_to_out_of_stock_product_variations', 10, 3 );

function form_to_out_of_stock_product_variations( $data, $product, $variation ) {

    if( CUSTOM_PRICE_TABLE($variation) )

        $data['variation_description'] = CUSTOM_PRICE_TABLE($variation) . $data['variation_description'],



    return $data;

}

Code goes in function.php file of your active child theme (or active theme). It should works.
