Cart PDF for WooCommerce

Add the following code snippet to your themes functions.php:

function child_theme_wc_cart_pdf_destination( $dest ) {
    if ( class_exists( '\WCCartPDF\Mpdf\Output\Destination' ) ) {
        $dest = \WCCartPDF\Mpdf\Output\Destination::INLINE;
    }

    return $dest;
}
add_filter( 'wc_cart_pdf_destination', 'child_theme_wc_cart_pdf_destination' );

Add the following code snippet to your themes functions.php:

/**
* Remove the default download cart button
*/
remove_action( 'woocommerce_proceed_to_checkout', 'wc_cart_pdf_button', 21 );


/**
* Replace the default download cart button with our own logic to display a login notice for guests
*/
function child_theme_wc_cart_pdf_button() {
    if( ! is_cart() || WC()->cart->is_empty() ) {
        return;
    }

    if ( is_user_logged_in() ) :
    ?>

    <a href="<?php echo esc_url( wp_nonce_url( add_query_arg( array( 'cart-pdf' => '1' ), wc_get_cart_url() ), 'cart-pdf' ) );?>" class="cart-pdf-button button" target="_blank">
        <?php esc_html_e( 'Download Cart as PDF', 'wc-cart-pdf' ); ?>
    </a>

    <?php else : ?>

    <p><a href="<?php echo get_permalink( get_option( 'woocommerce_myaccount_page_id' ) ); ?>" class="cart-pdf-login"><?php esc_html_e( 'Please login to download your cart as a PDF', 'wc-cart-pdf' ); ?></a></p>

    <?php 
    endif;
}
add_action( 'woocommerce_proceed_to_checkout', 'child_theme_wc_cart_pdf_button', 21 );

Try adding the following to your wp-config.php file:

define( 'WC_CART_PDF_THUMBNAIL_COMPATIBILITY', true );

Copy the PDF template from the plugin folder wc-cart-pdf/templates/cart-table.php into your child theme folder child-theme/woocommerce/wc-cart-pdf/cart-table.php.

From there you can modify the PDF template in your child theme.
