Hi, We have purchased pro version of the plugin. we have a condition, where we provide 5 product options and the user MUST select one option to proceed to checkout or else user cannot proceed to checkout. Can you please help with this condition?

Please try this snippet in your child theme’s functions.php:

add_action( 'woocommerce_before_checkout_process', 
    function() {
        $plugin = WJECF()->get_plugin( 'pro-free-products' );
        if ( ! $plugin ) return;

        //Don't checkout if no free gift selected
        foreach( WC()->cart->get_applied_coupons() as $coupon_code ) {
            $coupon = new WC_Coupon( $coupon_code );
            //Must the user select a free product?
            if ( ! $plugin->must_select_free_product( $coupon ) ) {
                continue;
            }

            $session_selected_products = $plugin->get_session_selected_products( $coupon_code );
            if ( empty( $session_selected_products ) ) {
                wc_add_notice( __('Please select your free gift.', 'woocommerce-jos-autocoupon'), 'error' );
                return;
            }
        }
    },
    20
);

Hello,
I updated this code on child theme function.php. No message is displayed when a customer doesn’t select free sample products.
Please look attached screenshot.

Oh, sorry there was an error in the script. Try this:

add_action( 'woocommerce_before_checkout_process', 
    function() {
        $plugin = WJECF()->get_plugin( 'pro-free-products' );
        if ( ! $plugin ) return;

        //Don't checkout if no free gift selected
        foreach( WC()->cart->get_applied_coupons() as $coupon_code ) {
            $coupon = new WC_Coupon( $coupon_code );
            //Must the user select a free product?
            if ( ! $plugin->must_select_free_product( $coupon ) ) continue;

            $session_selected_products = $plugin->get_session_selected_products( $coupon_code );

            if ( empty( $session_selected_products ) ) continue;

            foreach( $session_selected_products as $item ) {
                if ( $item->getQuantity() > 0 ) continue 2;
            }

            wc_add_notice( __('Please select your free gift.', 'woocommerce-jos-autocoupon'), 'error' );
            return;
        }
    },
    20
);
