quantity button on order review one page checkout

From my point of view, ( im not an expert on JS) this function is not updating the field correctly, or the update js function is not getting the new value.

    function wqb_action(iteration,q) {
      var qty=[].slice.call(document.querySelectorAll('div.quantity'));
      if(!qty) return;
      for(i=0; i<qty.length; i++) if(i==iteration) {
        v=qty[i].childNodes[3];
        if(!v) return;
        if(v.value<=1 && q<1) return;
        v.value=parseInt(v.value)+parseInt(q);
      }

Hi Alberto,

Thank you for reporting this issue, I found that One Page Checkout requires an onchange event to bubble to record the quantity change. Version 1.0.19 addresses the issue where the page does not refresh when using the WC plugin One Page Checkout. Please upgrade to 1.0.19, clear your cache, and let me know if the issue persists.

Thank you!

Hello @rermis ! it did worked! Thanks

but i had to change the hook action location so it would appear correctly….

//add_action('woocommerce_after_cart','wqb_cart');
add_action('woocommerce_review_order_after_cart_contents','wqb_cart');

AND

//add_action('woocommerce_after_add_to_cart_quantity','wqb_assets');
add_action('woocommerce_review_order_after_cart_contents','wqb_assets');

Hi Alberto,

Thank you, I appreciate the details. So that I can fix this in future versions, can you tell me if there is an issue if the hooks that you added for woocommerce_review_order_after_cart_contents is called in addition to the existing hooks? I am wondering whether the new hook needs a conditional statement specifically if the one page checkout plugin is installed.

Here is the Original templeate (tbody only) of the review-order-opc.php

<tbody>
			<?php
				do_action( 'woocommerce_review_order_before_cart_contents' );

				foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
					$_product = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );

					if ( $_product && $_product->exists() && $cart_item['quantity'] > 0 && apply_filters( 'woocommerce_checkout_cart_item_visible', true, $cart_item, $cart_item_key ) ) {
						?>
						<tr class="<?php echo esc_attr( apply_filters( 'woocommerce_cart_item_class', 'cart_item opc_cart_item', $cart_item, $cart_item_key ) ); ?>" data-add_to_cart="<?php echo $_product->get_id(); ?>" data-update_key="<?php echo $cart_item_key; ?>">
							<td class="product-name">
								<div class="product-remove" >
									<?php echo apply_filters( 'woocommerce_cart_item_remove_link', sprintf( '<a href="%s" class="remove" title="%s">&times;</a>', esc_url( wcopc_get_cart_remove_url( $cart_item_key ) ), __( 'Remove this item', 'wcopc' ) ), $cart_item_key ); ?>
								</div>
								<div class="product-details" >
									<?php echo apply_filters( 'woocommerce_cart_item_name', wcopc_get_products_name( $_product ), $cart_item, $cart_item_key ); ?>
									<?php echo wcopc_get_formatted_cart_item_data( $cart_item ); ?>
								</div>
								<div class="product-quantity">
								<?php
									if ( $_product->is_sold_individually() ) {
										$product_quantity = sprintf( '1 <input type="hidden" name="cart[%s][qty]" value="1" />', $cart_item_key );
									} else {
										$product_quantity = woocommerce_quantity_input( array(
											'input_name'  => "cart[{$cart_item_key}][qty]",
											'input_value' => $cart_item['quantity'],
											'max_value'   => $_product->backorders_allowed() ? '' : $_product->get_stock_quantity(),
											'min_value'   => '0'
										), $_product, false );
									}

									echo apply_filters( 'woocommerce_cart_item_quantity', $product_quantity, $cart_item_key, $cart_item );
								?>
								</div>
							</td>
							<td class="product-total">
								<?php echo apply_filters( 'woocommerce_cart_item_subtotal', WC()->cart->get_product_subtotal( $_product, $cart_item['quantity'] ), $cart_item, $cart_item_key ); ?>
							</td>
						</tr>
						<?php
					}
				}

				do_action( 'woocommerce_review_order_after_cart_contents' );
			?>
</tbody>

I had to edit it and added:
do_action( 'woocommerce_after_cart_item_quantity' );

right after:
echo apply_filters( 'woocommerce_cart_item_quantity', $product_quantity, $cart_item_key, $cart_item );

so that the button appear in the desired position.

Hello again @rermis .

For some reason the buttons show up but disappear right away.

Hi Alberto, was this taken using AutoCoupons version 1.0.21? Also, have you tried reversing the earlier edits to review-order-opc.php to see if the plugin works on it’s own? I would be happy to test this in more depth for you, but One Page Checkout is not a free plugin.
