Conditional Logic
For any field it is possible to set rules when to show or hide the field.
There are three types of this logic:
- Conditional Logic for Fields,
- Conditional Logic for Products and Categories,
- NEWConditional Logic for Shipping Methods
Conditional logic for fields
The conditional logic for fields allows showing fields based on values from other fields, created in the plugin, such as: checkbox, radio and select.
Select action for a field when rules match:
- Show this field
- Hide this field
and the required condition:
- All rules match (and)
- One or more rules match (or)
You can add any number of rules. Rules matching is based on a field type (checkbox, radio and select) and field option.
Checkbox will have two options: checked and unchecked.
For radio and select options will be configured manually.
Conditional logic for products and categories
The conditional logic for products and categories allows showing field by selected products or categories.
Select action for the field when rules match:
- Show this field
- Hide this field
and the required condition:
- All rules match (and)
- One or more rules match (or)
You can add any number of rules. Rules matching is based on a product or a product category in the cart.
Conditional logic for shipping methods
The conditional logic for fields allows showing fields based on selected shipping method.
Select action for a field when rules match:
- Show this field
- Hide this field
You can add any number of rules. Rules matching is based on selected shipping method. To select shipping method, choose the shipping zone first (you'll see only shipping methods in this shipping zone).
Conditional logic for fields required in WooCommerce
WooCommerce forces some fields to be required. The plugin does not change this setting.
Required fields:
- Country/Region
- State/County
- Postcode/ZIP
Some shipping and invoice plugins also require these fields to be completed. Therefore we do not recommend hiding them.
The configuration of the store affects the validation of such an incomplete form:
- how are shipping options set in WooCommerce (e.g. store address)
- what are the requirements for shipping plugins
- or what products are in the basket
Setting the store address as the customer default location solves the problem in most cases.
WooCommerce > Settings > General
Make sure hiding is possible and will not cause a validation error.
Assigning a price to the custom fields
Fields added using FCF have an additional tab "Pricing" with available options for assigning a price.
The impact on the final purchase amount depends on the selected price type and its value.
- Fixed - net price set in currency units and independent of the cart.
- Percentage of Subtotal (ex. VAT) - percentage amount related to the net subtotal (cart value).
- Percentage of Subtotal (incl. VAT) - percentage amount related to the gross subtotal (cart value).
- Percentage of Total - percentage amount related to the Total (cart value + coupons + shipping).
The option to add a price is available for:
- Single Line Text
- Paragraph Text
- Checkbox
- Radio button
- Select (Drop Down)
- Multi-select
- Date
- Time
- Color Picker
- File Upload
Instructions for adding a price to the field
- Add a new field.
- Add options and other settings - if required by the selected field type (e.g. "Radio" field).
- Select the "Pricing" tab and check the "Enable Pricing" checkbox.
- One line of settings will appear if the selected field has no option (e.g. "Single Line Text").
- There will be separate lines with settings next to each option if the selected field has options (e.g. "Select").
- Assign a price by selecting its type from the "Price Type" list:
- Fixed - enter the net price
- Percentage of Subtotal (ex. VAT) - enter a percentage
- Percentage of Subtotal (incl. VAT) - enter a percentage
- Percentage of Total - enter a percentage
- Indicate the tax class by selecting the class from the "Tax Class" list. Save the changes.
This option will appear when the assigned price is greater than "0" and if the "Enable tax rates and calculations" option is enabled in the WooCommerce > Settings > General tab.
Displaying prices in the store
The price assigned to the field will be shown in the store either as a gross total price or as a percentage.
- Checkout - the price will be shown in brackets next to the field label (or next to an option) and will also appear in the "Order" section.
- Order Summary - the price will be shown as the amount included in the purchase.
- WooCommerce > Orders tab - the fields visible there are editable so it is possible to change the label and price or to add tax.
Important information
- Enable the "Rounding" option in the WooCommerce > Settings > Tax tab. This setting is required when more than one price field is added.
- Do not use the same labels.
- The fields added in the "Billing" and "Shipping" sections are cached. These fields are saved and autocompleted during next purchases.

Settings
Go to menu WooCommerce → Checkout Fields → Settings.
CSS jQuery UI - in the plugin's settings, you can disable loading of the CSS jQuery UI file. The CSS file is used to style some additional fields in the order (i.e. Date field), but it may cause conflicts with other plugins that also make use of jQuery UI (i.e. to create tabs). If you notice any problems when displaying your shop, try to disable this CSS file.
Custom Sections - you can add custom sections to checkout. Check custom sections and click Save changes. New sections will show up in tabs in the plugin menu.
Below you can see all custom sections on Storefront 2.1.1 example. For better presentation, the theme was modified to one column view in checkout by Storefront Checkout Customiser.
Custom Sections
After adding custom section go to it's tab, add new fields and edit sections. You can set Section title, Section titile tag and CSS class.
All fields in the "Biling" and "Shipping" sections are cached, which means that when placing the next order, they will be completed or marked in accordance with the previous order.
Cached sections:
- Before Customer Details
- After Customer Details
- Before Billing Form
- Billing
- After Billing Form
- Before Shipping Form
- Shipping
- After Shipping Form
Non-cached sections:
- Before Order Notes
- Order
- After Order Notes
- Before Submit
- After Submit
Usage Examples
Additional Agreements at the Checkout
You can add additional checkboxes that will appear directly over the button used to placing an order. Here you can also add options, such as: consent to send a newsletter or other sign ups to which the user should agree. Every added checkbox can be made obligatory or optional.
In plugin settings add custom sections Before Submit. Next:
- Add field type Checkbox and expand field to editing.
- Check Required field if you want to require this option.
- Enter the label of the checkbox.
- Enter the value of the checkbox (e.g. Yes, Selected, etc.). The value will be displayed only in the order preview if the checkbox was selected by the user. It's meant for the administrator only.
- Optionally, enter the CSS class.
- Click Save Changes.
Information on selecting the checkbox in the order
If the checkbox has been selected by the user, the information appears in the details of the order:
Displaying values of fields using custom PHP code. For advanced users
If you would like to display a value of specific field entered by your customer in the checkout, use below PHP code:
echo $order->get_meta( 'meta_name');
To learn a meta name (the name that the field is written under in the database), check the field's configuration:
So, in this example: to display VAT Number field value with meta name _billing_vat_number, use below PHP code:
echo $order->get_meta( '_billing_vat_number');
Deleting the changes
To reset sections settings click "Reset Section Settings" button. For standard sections (Billing, Shipping, Order) custom fields will be deleted and standard fields will be reset to their default state, and for additional sections, all fields will be deleted.
