Customer order notes causes errors and multiple orders
-
If customers provide order notes in checkout process it can cause weird behaviour.
As long as the order notes only consists of text messages, everything works fine. But as soon as someone types symbols like
*':/"() {} [] ~©¢¥€¿¡¦¬;into the order notes field or inserts emojis from his or her mobile phone and places an order, it causes an error like
Error processing checkout. Please try again.
or even worse creates infinite loading times and places orders with an weird amount of items. Every ordered item, shipping fees and VAt lists up to 3 times in the order overview. Additionally woocommerce is adding all these items to the subtotal (but the total amount stays correct).
Need some help with this as it’s close to crashing my website. Gonna deactivate the customer order notes for now, to prevent damage, but would like to see a fix for this issue!
Thanks for your help!

Hi @inkvader
If customers provide order notes in checkout process it can cause weird behaviour. As long as the order notes only consists of text messages, everything works fine. But as soon as someone types symbols like
*':/"() {} [] ~©¢¥€¿¡¦¬;into the order notes field or inserts emojis from his or her mobile phone and places an order, it causes an error likeError processing checkout. Please try again.From what I understand, you’re experiencing an issue with special characters in the order notes field causing errors or irregular behavior during the checkout process.
First off, good job on quickly disabling the customer order notes feature. This is a smart move to avoid further issues while we figure out a solution
Today, I’ve tested this issue on my own site, using the most recent versions of WordPress, WooCommerce, and our free Storefront theme, with no other software enabled. However, I was unable to replicate the issue you’re experiencing.

From what you have described, it could be code from another plugin or theme which has caused a possible conflict and affected the functionality of WooCommerce.
To check if this is the case, I recommend conducting a conflict test on your site. You can do this by disabling all other plugins except WooCommerce and switching to a theme like Storefront. This will help us pinpoint any installed software that might be causing the issue. A free plugin called Health Check and Troubleshooting can be used for this testing.
When in Troubleshooting mode all plugins will be deactivated and only the admin of the site carrying out the troubleshooting would see those changes. Any customers visiting the site would see no changes at all.
Once you’ve disabled all other plugins and switched themes, if the issue is resolved, you can reactivate your theme and plugins one by one. Test after each reactivation until the issue reappears, which will help you identify the problematic software.

Thanks in advance for your cooperation. We’re ready and eager to help you resolve this issue as soon as possible.
Thanks for your answer!
I made a copy of my website to be able to test some things.First of all I updated from PHP Version 7.4 to 8.2 and had to delete all woocommerce language files in wp-content/languages/ because some language file was causing an error. Not sure if that did change anything in the end.
I switched to storefront theme, deactivated every plugin except woocommerce and then tried a lot and made a ton of test orders to be able to replicate the problem. What I found is the following:
I haven’t been able to replicate the issue with special characters any more. (I feel that it sometimes causes weird behaviour, but can’t say for sure.)
What I was able to replicate: If I am ordering from a mobile phone, inserting a lot of emojis into the order notes checkout field I get this error: “Error processing checkout. Please try again.”.
Because I am still on the checkout page, I can delete all emojis from order notes field and insert any text instead (or leave it empty). The order is submitted now, but every product, shipping costs and taxes are listed two or three times in the order.(Tested on Android with Chrome and on iPhone with Safari)
Is there any chance you could replicate this exact issue?
My best chance by now is propably to disable emojis in wordpress…Hello @inkvader,
Customer #1 puts article X and Y into the cart, then tried to checkout, which failed with an error, because he used emojis in order notes field. Customer #1 the leaves the site without completing checkout.
I’m not able to reproduce this as you can see below. Could you please try updating to WooCommerce version 8.0.1?
You can refer to this guide for step-by-step instructions.

Sounds like caching misconfiguration to me. To verify this, please turn off all caching solutions from plugins or through your hosting provider, then try repeating these steps.
Let us know how it goes!
