Description
Show a Field Only When the Order Calls for It
Checkout Fields for Blocks – Conditional Logic for Fields attaches visibility rules to individual fields on the WooCommerce block-based checkout. A field appears when its conditions are met and stays hidden when they are not. That is the whole idea, and it changes how a checkout form can be built. Instead of one long form that every customer scrolls through, each buyer sees only the inputs that apply to their cart, their shipping choice, their payment method and their location.
This Checkout Fields for Blocks – Conditional Logic for Fields WordPress plugin is an add-on. It extends the free Checkout Fields for Blocks plugin, so the fields you already created there gain a new Conditional Logic option. You select a field in the checkout form editor, switch the option on, and define the rules. No template overrides, no hooks, no snippets pasted into a theme.
The strongest capability is the range of things a rule can look at. A single field can react to what is in the cart, how the order will ship, how it will be paid for, what it totals, what day it is, and where the customer lives. Combined with comparison operators, that covers most real checkout requirements that normally push store owners toward custom development.
Rules built from real order data
Rules are assembled in an interface inside the checkout form editor. You choose the condition type, pick an operator, and enter the value to compare against. Because the conditions draw on live checkout data, the form responds as the customer changes their selections. Switch from standard to express shipping and a delivery-instructions field can appear. Choose a different payment gateway and a field tied to the previous one disappears.
Complete Feature Set
The plugin groups its conditions by the kind of information they evaluate. Each one maps to a situation WooCommerce store owners run into regularly.
Condition types
- Cart-based rules: reveal a gift message field only when a specific product is in the cart, so buyers of unrelated items never see it.
- Shipping method rules: request extra details, such as a contact number or access notes, when express shipping is selected.
- Payment method rules: display card-related fields only for credit card payments and keep them out of the way for other gateways.
- Order value rules: trigger special fields once the cart exceeds an amount you define, for example a field for a corporate purchase reference on larger orders.
- Date-based rules: activate fields during a defined window, such as a Black Friday campaign or a holiday promotion, and let them drop away afterwards.
- Product attribute rules: add an engraving or personalization input when a product supports it.
- Customer location rules: show fields to shoppers in particular countries, which suits tax identifiers or region-specific declarations.
- User role and product category rules: separate the experience for VIP customers, wholesale accounts or specific product groups.
Operators
Conditions are only as useful as the comparisons behind them. The plugin supports equals, not equals, contains, greater than and less than, among others. Equals handles exact matches such as a specific shipping method. Not equals lets you invert a rule, showing a field to everyone except a particular group. Contains is handy when you match part of a value. Greater than and less than are the natural fit for order totals.
Fields that respond to other fields
Conditions can also depend on values chosen within the checkout itself. A customer who ticks an option or selects an entry from a dropdown can open up a follow-up field. This keeps optional detail optional. The shopper who does not need it never meets it, and the shopper who does gets a prompt at exactly the right moment.
Interface-driven setup
Everything is configured through the editor. Rules are readable, so returning to a field months later and understanding why it appears takes a glance rather than a code review. Because the plugin is GPL-licensed, you can also inspect and adapt it as your project requires.
How Does It Fit Into Your Checkout Workflow?
The plugin does not replace your checkout setup. It sits on top of it. You begin with the free Checkout Fields for Blocks plugin, where you create and arrange the fields your store needs. Then you install and activate the Conditional Checkout Fields add-on, and each field gets access to conditional logic.
The working sequence is short. Open the WooCommerce checkout form editor. Select a field. Enable Conditional Logic. Define when the field should appear. Save. From that point the checkout adapts on its own, with no further steps for you or the customer.
This matters for maintenance. Rules live alongside the fields they control, so a change to a promotion or a shipping policy means editing a rule rather than hunting through theme files. You can add a seasonal field, set the date range, and let the date condition do the rest. When the campaign ends, the field stops appearing without anyone remembering to remove it.
The result for customers is a shorter, clearer form. Fewer visible inputs mean fewer decisions and less scrolling, and that tends to be what store owners are after when they trim a checkout. The plugin gives you the means to do that selectively rather than by deleting fields that some orders genuinely need.
Ideal Use Cases
Gift and personalized product stores
A shop selling both ordinary and customizable goods can tie a gift message to the relevant products and an engraving field to items whose attributes allow personalization. A customer buying a standard item checks out without seeing either. A customer buying an engraved piece gets the input in the right place, before payment rather than in a follow-up email.
Stores with varied shipping options
Express delivery often needs information that standard delivery does not: a phone number for the courier, a preferred time window, building access notes. A shipping method rule requests those details only when they matter. Standard-shipping customers are spared the extra fields.
Promotional campaigns
Date-based conditions suit time-boxed offers. Add a field that captures a promotional code source or a campaign-specific preference during a Black Friday sale, then let it expire on schedule. Order value rules work the same way for thresholds, such as a special instruction field for carts above a chosen total.
VIP, wholesale and role-based experiences
User role conditions let you give trusted or professional buyers their own fields, such as a purchase order number, while retail customers see the standard form. Product category rules add another axis, so a store with a regulated category can request additional declarations for just those items.
International stores
Customer location rules show fields only in selected countries. A tax or registration identifier required in one region does not need to clutter the form for everyone else. Agencies building multi-region WooCommerce stores for clients gain a way to keep a single checkout while respecting local requirements.
Agencies and developers
Client requests like “only ask this if they pick that” usually become small custom code tasks. Handling them through a rule interface shortens delivery and makes the logic visible to non-developers on the client side.
Frequently Asked Questions
Does this plugin work on its own?
No. It is an add-on for the free Checkout Fields for Blocks plugin, which provides the fields and the checkout form editor. The conditional logic option appears on the fields you create there. Without the base plugin there are no fields for the rules to control.
Can one field depend on several conditions?
You define the rules for when a field should appear, drawing on condition types such as cart contents, shipping method, payment method, order value, dates, product attributes and country. Operators like equals, not equals, contains, greater than and less than let you express each comparison precisely. This lets a single field respond to the specific circumstances that matter for it.
Can I use it for a limited-time promotion without removing fields afterwards?
Yes. Date-based rules activate a field for a defined period such as a Black Friday or holiday campaign. Once the period passes, the field no longer appears. Nobody has to remember to turn it off, and the rule stays in place if you want to reuse it next season.
Can I show different fields to different customer groups?
Yes. User role and customer location conditions let you vary the form by who is buying and where they are. A VIP or wholesale account can see fields that retail shoppers do not, and shoppers in selected countries can be asked for region-specific details. Everyone else gets a shorter form.
