How to display order summary on checkout page? - php

Question

I am working on a woo-commerce theme and it's good but on the checkout page clients want's to change the order of some blocks. so he wanted to move payment methods before order summary. I did that by adding the code in function.php which is given below. The code works fine but after adding the code i can't see order summary on checkout page. I can't see Subtotal, Shipment and Total Cost. I don't know what is wrong with this code. please help me out with this.
add_action( 'woocommerce_checkout_order_review', 'reordering_checkout_order_review', 1 );
function reordering_checkout_order_review(){
remove_action('woocommerce_checkout_order_review','woocommerce_checkout_payment', 20 );
add_action( 'woocommerce_checkout_order_review', 'custom_checkout_payment', 8 );

You can also check with:
add_filter( 'woocommerce_checkout_fields' , 'custom_order_comments_checkout_fields' );
function custom_order_comments_checkout_fields( $fields ) {
if ( !WC()->cart->is_empty()):
$output = '';
$count = 0;
$cart_item_count = WC()->cart->get_cart_contents_count();
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ):
$count++;
// Displaying the product title
$output .= 'Product title: ' . $cart_item['data']->post->post_title;
// New line (for next item)
if($count < $cart_item_count)
$output .= '';
endforeach;
$fields['order']['order_comments']['default'] = $output;
endif;
return $fields;
}
