WooCommerce: Deny Checkout if User Has Pending Orders

As WooCommerce snippet requests by #BloomerArmada fans keep coming to my inbox, it’s time to publish a very useful functionality.

Today, we’ll see how to deny purchasing to a given billing email address, if this is a user and happens to have a pending order already!

Deny checkout if user has a pending order in WooCommerce

add_action('woocommerce_after_checkout_validation', 'bbloomer_deny_checkout_user_pending_orders');

function bbloomer_deny_checkout_user_pending_orders( $posted ) {
global $woocommerce;
$checkout_email = $posted['billing_email'];
$user = get_user_by( 'email', $checkout_email );

if ( ! empty( $user ) ) {
$customer_orders = get_posts( array(
        'numberposts' => -1,
        'meta_key'    => '_customer_user',
        'meta_value'  => $user->ID,
        'post_type'   => 'shop_order', // WC orders post type
        'post_status' => 'wc-pending' // Only orders with status "completed"
) );
foreach ( $customer_orders as $customer_order ) {
        $count++;
}
if ( $count > 0 ) {
	wc_add_notice( 'Sorry, please pay your pending orders first by logging into your account', 'error');
}
}

}

Where to add this code?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such delicate files - if you need more guidance, please take a look at my free WooCommerce Customization video tutorial.

Does this snippet still work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.

  1. Hi

    Can you tell me if the code still works?

    I used in wordpress version 4.9.4, woocommerce version 3.3.3 and php 7.1. Hostgator hosting.

    The theme, is a free of the wordpress repository, is called Envo Business.

    I did some tests, and it did not work around here.

    1. Hey Sandro, thanks so much for your comment! It definitely should work, I don’t see why not. Users must be registered (no guest users) and their order status must be “pending” (not “on-hold” etc.). Let me know

  2. You can actually just grab the current WP user instead of get a billing email. You can also just do a direct PHP count() on the orders to get the number of pending orders. Cleaned it up a little with these two items.

    add_action('woocommerce_before_checkout_form', 'bbloomer_deny_checkout_user_pending_orders');
    function bbloomer_deny_checkout_user_pending_orders( $posted ) {
        global $woocommerce;
    
        // Get current customer/user
        $customer = wp_get_current_user();
    
        // If user is not empty, get orders
        if (!empty($customer)) {
            $customer_orders = get_posts(
                array(
                    'numberposts' => -1,
                    'meta_key'    => '_customer_user',
                    'meta_value'  => $customer->ID,
                    'post_type'   => 'shop_order', // WC orders post type
                    'post_status' => 'wc-pending' // Only orders with status "completed"
                )
            );
    
            // Check number of pending customer orders
            if ( count($customer_orders) > 0 ) {
                wc_add_notice('Sorry, please pay your pending orders first by logging into your account', 'error');
            }
        }
    }
    
    1. Thanks so much Bobbie, much appreciated!

  3. Cool snippet. Bravo!

    Can we deny if only customer have 2 pending order (not one in snippet). Sometimes customer made split order in their purchasing, 2 pending order is more convenient treat.

    Thanks rodolfo, youre cool. Kind regards

    1. Thanks Thomas! Yes, of course, that’s why I put a counter in the PHP – just change that to:

      if ( $count > 1 ) {
      
  4. Very useful, thank you!
    I’m trying to find a way to do something similar…. I need to deny the checkout (or hide the add to card button in the single products page) if a customer has already bought ( in other orders) a certain product in the past and try to buy it again.

  5. Hi Rodolfo
    I’m a bit confused here apologies. If a customer selects items to purchase and then checks out before completion, then transaction stops. So should they return the process just begins again. I can see merit in previous post ‘re b2b where credit is involved.
    I might not be getting this.

    1. No worries Denis! So my thinking is that if a user goes to checkout, completes all the info, goes to the payment page and does not complete the order – then I would like to block such user to keep placing orders until they pay the previous. Of course, this will need to be coupled with an email reminder “please pay your pending order” before stopping them from placing another one.

      Note that the order will go into “pending” only if they click on “proceed to payment” button e.g. they go to PayPal ๐Ÿ™‚

  6. Interesting snippet Rodolfo!

    Would be cool if this can be extended to accomodate a custom field “max_allowed_credit” which can be set at user profile by merchant.
    This way you can use it in a B2B environment where clients often can buy with conditions like invoice 30 days net. But when the total amount is larger than X EUR/US$, then show this notification.

    Another cool trick would be to dynamically change the available payment methods.
    As long as they have no pending orders/payments, allow payment via COD/check/invoice net x days. If they have, then hide those options and only show prepaid methods like paypal, creditcard, etc…

    1. Cheers Fabio, nice ideas ๐Ÿ™‚
