How to Add to Pay Order Button for Pending Payment Orders on View Order Page in WooCommerce

You’d think that when a customer views an order and the order has a pending or failed status, they should be able to pay right from that view order page, right? Yeah, but nope. The view-order template just renders the order info.

The Order Listing page does, however, include a Payment button though.

Why This Feature is Important

Allowing customers to pay directly from the view order page enhances user experience and reduces the friction in completing a purchase. This is particularly useful for orders that have failed or are pending, as it provides a quick and easy way for customers to complete their payment without navigating through multiple pages.

The Challenge

The default WooCommerce view-order template does not include a pay button. You can add this functionality by either customizing the WooCommerce View Order Template or by using WooCommerce hooks. I recommend the latter because customizing template files can lead to issues when WooCommerce updates its templates, potentially breaking your customizations if they are not kept up-to-date.

Adding the Pay Order Button Using Hooks

To add the pay order button, you need to add custom code to your functions.php file or create a custom plugin. Below, I'll show you the code you need and where to place it.

The Solution

The solution should look like this.

Here's a straightforward solution using hooks to add the payment button to the view-order page. This method ensures your customizations remain intact even after WooCommerce updates.

Copy and the following custom php and then you can paste it into functions.php file (omit the <?php opening tag because functions.php has one already otherwise your site will start showing php content and you won't want that.) or use a WordPress Plugin Generator (recommended approach) and copy and paste the code there. If you have used the plugin generator you'll only need to activate the plugin.
