WooCommerce Checkout Fields Editor

To proceed with this guide you'll need a plugin because WooCommerce does not have conditional logic built in.

We created Flexible Checkout Fields. One of the most powerful features that we developed in the plugin is the support for conditional logic.

But don't just take our word for it, over 80,000 WooCommerce stores worldwide use the plugin daily.

We often add new features or fix bugs in this plugin. People really appreciate it!

This plugin also utilizes the WordPress look & feel and is very easy to use due to the clean interface.

👉🏽 Have a look before we start:

What's more, you can download Flexible Checkout Fields for free! Watch this video to see what this plugin offers you in the free version:

WooCommerce conditional checkout fields features

Now I will show you how to configure conditional logic for a phone field.

👉🏽You will need the PRO version as the free one doesn't support WooCommerce conditional checkout fields.

You can configure conditional logic in three ways, for:

• fields,
• products or categories,
• selected shipping method.

I will show you all of them.

We will use the WooCommerce checkout conditional fields feature with a checkbox field. We'll configure that a phone field shows up when a customer marks a Show phone? checkbox.

Phone field checkout conditional logic

First, you need to create a new custom field.

Select Checkbox as a field type. Set Show phone? as a label:

Meta name will be the name of the field in your database. You don't need to change the default one.

Click Add Field. Then, as you can see, the field shows up on the configuration screen:

Go to the Phone WooCommerce default field and click the Conditional logic tab.

You'll find WooCommerce checkout conditional fields settings here:

Mark the Enable conditional logic based on FCF fields checkbox:

Add a new rule. Select the custom field in the rule (Show phone?).

Save settings and you're ready to go.

Look:

🎉 It works as we wanted!

Product/Category checkout conditional logic

💡There is a second way you can configure your fields.

You can use product/category conditional logic as well.

Let's say you sell T-Shirts with custom projects. You want your customers to be able to describe their projects to you. Also, you need a phone number to discuss the project with them.

There is a default Phone field in checkout but maybe your customers would like to provide another phone number. This way they can guide you directly to the Marketing Manager instead of the Accounting or Office Manager.

👉🏽So we need such fields:

When a customer selects the second option, another phone field pops up:

How to configure these fields this way?

First, you need to add these fields:

(The 'T-Shirt Custom Project' is simple HTML text. I used the <strong> HTML tag to bold it).

Then, you need to configure conditional logic:

👉🏽As you see, I configured the plugin to show the field when a cart contains a T-Shirt - Custom Project product. You need to configure conditional logic the same way for the next two fields.

However, for the last field (Your phone number), you need to use fields conditional logic instead. That's because the plugin should display this field when a customer selects a specific option in the radio field. I mean the 'I want to provide another phone number to discuss the project' option.

👉🏽Look:

Also, you can use phone number validation for this field:

VAT number conditional checkout field

You can use conditional logic for the VAT number field as well.

👉🏽By default, WooCommerce shows the Company name field right after the First name and Last name fields. The field is optional. However, it's better to hide it unless a customer wants an invoice.

You can simply move the field to the bottom. Next, you can simply create an I want an invoice checkbox and a VAT Number field.

Then you need to configure conditional logic for the Company name and VAT Number fields.

Remember to set these fields as Required.

Look at the final effect:

💡Bonus: There is another solution.

Flexible Invoices for WooCommerce

We created the Flexible Invoices plugin. Not only it adds a VAT number field but also validates the VAT number your customers provide.

Shipping Method conditional checkout field for WooCommerce

With this feature, you'll be able to show or hide checkout fields when a customer selects a certain shipping method on the checkout page. To do that, just check Enable conditional logic based on shipping methods and add a new rule. 

In the Rule section, you'll see a select field. In the first one, select the country for which you do not want to show shipping methods. Select Shipping Zone, you can choose the shipping zone that includes your shipping method. And then, in the second field, Select Shipping Method, choose your shipping methods that are included in the selected shipping zone. Here I have used the shipping method I have configured with the Flexible Shipping plugin.
