Hello.

I wasted a week trying to solve the problem with my shipping calculator on product page. Everithing works fine if I have one destination country. But when I added second contry – it doesn’t work!

I decided to test on clear site. And fantastic – the same issue!

Now I have: clear WordPress 6.1.1 and Woocommerce. Nothing else.

I and one product. Add Sell to cpecific countries.

Add Shipping zones.

Enabled shipping calculator on the cart page.

Add product to the cart. On the cart page if I select Germany and it zip code – calculator works.

If I select Netherlans or Belgium, enter matches zip code then I receive an error <strong>Please enter a valid postcode / ZIP.</strong>

I would be very appreciated if anyone tell me what’s happening and what am I doing wrong?

P.S. After some tests I found the second magic. I added in shipping zones to every region ‘Europe’ (means ‘Europe, Germany’; ‘Europe, Netherlands’; ‘Europe, Belgium’). On the cart page in the shipping calculator I choose ‘Germany’ and any of existing zip code from other region – then calculator works! But the country is wrong!

Hi @prizzrak

Thanks for reaching out!

Can you please share with us a clear screenshot of what you see on your end so that we could address you more effectively?

If you don’t already have a screenshot service installed, you can try https://snipboard.io or http://skitch.com/. You can share the direct link to the image as a response to this topic.

Meanwhile, I checked your site, added some products to cart, entered Germany as the shipping country, however, I am receiving a different error message here:

Thanks for sending the System Status Report, however, what you provided is incomplete. Please share your System Status Report that you can find via WooCommerce > Status. Select Get system report and then Copy for support. Once you’ve done that, you can paste it into your reply here.

WC Version: 5.6.2

Based on the information provided, please update WooCommerce core to the latest version since the version you are using is quite old.

Looking forward to your reply.

Hello.

You show screenshot from checkout page, but I’m talking about the cart!

I need shipping calculator in cart.

Once againe I add screenshots of my settings.

Sell to specific countries. https://snipboard.io/ZAI6lL.jpg

Add Shipping zones. https://snipboard.io/TJQDfU.jpg

Now go to the cart, select any shipping country and its zip except first one (Germany).

For example Netherlands 54000. https://snipboard.io/3NlTIj.jpg

“Update” and the error is “Please enter a valid postcode / ZIP” but zip I entered is valid! And it works with the first country I added in admin panel (in my case Germany), but doesn’t works with any other. https://snipboard.io/5W49xE.jpg

Based on the information provided, please update WooCommerce core to the latest version since the version you are using is quite old.

I can’t update WooCommerce because I need to use some plugins that work only WC not higher 5.6.2! There are many different plugins that work quite good only on quite old WC!

Hi @prizzrak

I need shipping calculator in cart.

Thanks for providing further context to your issue here.

I replicated the scenario on my personal site, however, I am unable to reproduce the issue here.

Cart page:

Checkout page:

I understand, however, in this case, you might experience such problems on your site, since you are using a very old version of WooCommerce already.

Should you wish to test the latest version of WooCommerce, I’d recommend cloning your site to a staging environment without modifying your live site or impacting customers. Many hosts provide staging facilities, so it’s worth checking in with them. It’s also possible to do it using the free WP Staging plugin.

Hope this helps!

Did you replicate the same shipping zones? At least 2 counties? The first country (in admin panel listing) works, but the second doesn’t.

Should you wish to test the latest version of WooCommerce,

Why do you wish me to update, even I explained that it’s impossible in my case?

And meanwhile don’t you have an intention to solve the issue? All can you suggest is only to update to the latest version?

I’d be very appreciate to receive from you – as from the plugin developer – any solution to resolve my issue.

What hooks/filters can I use with shipping calculator in the cart?

At least where can I find the technical data how shipping calculator works? Ajax calls, functions, hooks? Or is this information prohibited?

Hello,

I understand this could be a frustrating issue, 🙁 I was checking on my end, I replicate the same shipping zones, but I could not reproduce the same problem.

I understand the version of WooCommerce could not be updated easily in your case. Kindly note that WooCommerce is not a static software, it is dynamic, it is constantly making enhancements. And please note in this forum we highly recommend using any of the last 3 versions of WooCommerce Core.

To help you investigate further, please provide us with the following information:
- Please share a complete copy of your site’s System Status Report? It is under WooCommerce > Status. Select “Get system report” and then “Copy for support”.
- Please share a copy of any fatal error log found under WooCommerce > System Status > Logs (if any).
Kind regards.

Hello.

Please share a complete copy of your site’s System Status Report? It is under WooCommerce > Status. Select “Get system report” and then “Copy for support”.

Full status in my prev. message.

Please share a copy of any fatal error log found under WooCommerce > System Status > Logs (if any).

There is no errors in logs.

but I could not reproduce the same problem.

According to your screenshot it is not clear to understand what happened next. I can give you admin access to my site if needed.

What about my last questions?

What hooks/filters can I use with shipping calculator in the cart?

Hello @prizzrak,

> And meanwhile don’t you have an intention to solve the issue? All can you suggest is only to update to the latest version?

I tried replicating the problem and found some answers.

But before that I would like to clear this part, we asked you to update because we can only provide support for the latest releases of WooCommerce as per our support policy.

The problem seems to be caused because of the Netherlands zip code format. You can test this yourself by adding the following zip code 5682. Without the JH part at the end (5682 JH) which is how it should be formatted it will render the same error.

This was discussed in the following GitHub report: https://github.com/woocommerce/woocommerce/issues/23901

You can add the snippet provider here to your site as a workaround.

Hope this clears up the confusion! 😀

It took 4 answers and waste of a lot of your and my time to solve the issue. And the solution is as excepted – to disable “very useful” build in functions! Your support and support policy is awful. Why it needed to collect my data and give null answers if the problem is in your functions? And even support doesn’t know how your plugin works!

Thanks to @babylon1999 for GitHub link. That snippet is needed to all countries.

Hi,

I’m sorry for the experience you had.

To clarify, please note the information requested is not sensitive, the system status report does not include sensitive information. Sorry for asking that.

That snippet is needed to all countries.

I am not a developer, but if you would like to add the same condition (to not enforce the postal code formatting) to all the countries you sell products, i.e. DE, NL, BE, and LU, the snippet will look like this:

add_filter( 'woocommerce_validate_postcode', 'custom_disable_nl_postcode_validation', 10, 3 ); function custom_disable_nl_postcode_validation( $valid, $postcode, $country ) { if ( 'NL' === $country || 'DE' === $country || 'LU' === $country || 'BE' === $country ) { return true; } return $valid; }

I hope this helps.
