A Complete Guide to WordPress Form Field Types

Adding a field to your form is easy. Configuring it well — so it collects clean, valid, and genuinely useful data — is what separates a form that works from one that floods your inbox with junk and half-finished entries. The secret is choosing the right WordPress form field types and setting each one up properly.

Koala Forms gives every field a set of configuration panels right in the block editor sidebar. This complete guide walks through each field type you get, when to use it, and the settings that matter most — including validation, required fields, and input masking.

Where field settings live

Click any field in the editor and its settings appear in the sidebar on the right, organized into clear panels:

• General — label, field name, placeholder, help text, and whether the field is required
• Validation — rules that check the visitor’s input before the form can submit
• Field-specific settings — options unique to that field type, such as dropdown choices, number limits, or file restrictions

The settings every field shares

No matter which field type you choose, a few core settings apply:

• Label — the text visitors see above the field. Keep it plain and specific.
• Display Label vs. Field Name — the label is what users read; the field name is the unique internal key used to store and reference the submission. Keep names unique and descriptive so your entries stay readable.
• Placeholder — the light hint text inside an empty field. Use it to show an example of the expected format, not just repeat the label.
• Help text — a short instruction shown near the field for anything that needs explaining.
• Required — toggle this on to prevent the form from submitting until the field is filled in.

Every Koala Forms field type explained

Text field

The workhorse of any form, for names, subjects, and short answers. Beyond the basics, the Text field supports input masking — forcing input into a set pattern (like a postal code or reference number) as the visitor types, which keeps your data consistent.

Email field

Automatically validates that the entry looks like a real email address. Use it for any field you plan to reply to — it prevents typos that would otherwise bounce your notifications.

Number field

Collects numeric values only, and lets you set minimum and maximum limits. Perfect for quantities, ages, or a guest count capped at, say, 1–10.

URL field

Checks that the entry is a valid web address. Ideal for portfolio links, company websites, or social profiles.

Phone field

A dedicated field for phone numbers, with masking to keep formatting consistent across submissions — no more mixed formats to clean up later.

Textarea (Paragraph)

For longer, free-form answers like messages, feedback, or descriptions. Set the number of rows to control how tall the field appears.

Dropdown (Select) and Multi-Select

Let visitors choose from a defined list. Add your options in the field settings. Use a standard Dropdown when only one choice is allowed, and Multi-Select when visitors may pick several.

Radio Buttons and Checkboxes

Both present a visible list of options. Radio buttons are for choosing exactly one option; checkboxes allow several. Because all choices are visible, they’re great when you want visitors to see every option at a glance.

Date field

Adds a date picker so visitors can’t enter an ambiguous or invalid date. Essential for bookings, event dates, and deadlines.

Address field

A grouped field for street, city, state/region, and postal code, with built-in region lists for many countries. It’s collapsible in the editor, so it doesn’t clutter your layout while you build.

File Upload field

Lets visitors attach documents, images, or PDFs — think resumes, screenshots, or supporting paperwork. You can restrict the accepted file types, and the maximum file size is governed by the ceiling set in Global Settings.

Disclosure / Consent field

A checkbox for terms acceptance or GDPR consent. Use it whenever you need a recorded agreement before a visitor can submit — for example, “I agree to the privacy policy.”

Step by step: configure a field properly

1. Select the field in the editor to open its settings.
2. In the General panel, write a clear label and toggle Required if the field is mandatory.
3. Open the Validation panel and add any rules — a minimum length, a pattern, or an input mask.
4. For choice or number fields, open the field-specific panel and set your options, limits, or accepted file types.
5. Click Update to save your changes.

Configuration tips that improve data quality

• Use the right type for free validation. A Number field for quantities and an Email field for addresses validate input automatically — no rules to write.
• Only require what you truly need. Every required field is a small barrier to completion. Be ruthless about what’s mandatory.
• Write helpful placeholders. Show the expected format (name@company.com, +1 555 123 4567) rather than repeating the label.
• Add input masking for formatted data. Phone numbers and reference codes stay clean when you mask them at entry.
• Explain unusual fields with help text. A one-line hint reduces errors and support questions.

Frequently asked questions

What field types does Koala Forms support?
Text, Email, Number, URL, Phone, Textarea, Dropdown (Select), Multi-Select, Radio Buttons, Checkboxes, Date, Address, File Upload, and Disclosure/Consent — plus the Step block for multi-step forms.

How do I make a field required?
Select the field, open the General settings panel, and switch on the Required toggle. The form won’t submit until that field is completed.

Can I validate that an email or URL is real?
Yes. The Email and URL field types validate their format automatically, and the Validation panel lets you add extra rules like minimum length or input masks.

What is input masking?
Input masking forces input into a set pattern as the visitor types — for example, formatting a phone number consistently. It’s available on Text and Phone fields.

How large a file can visitors upload?
The File Upload field respects the maximum size configured in Koala Forms → Global Settings, which is also capped by your server’s real upload limit.

Key takeaways

• Choosing the correct WordPress form field types gives you cleaner data and free validation.
• Every field shares core settings (label, name, placeholder, help text, required), plus type-specific options.
• Use Number, Email, and URL fields for automatic validation, and input masking for consistently formatted data.
• Keep required fields to a minimum, and configure the Validation panel to catch bad input before it’s submitted.

With your fields configured to collect exactly what you need, your form is ready for the world. The next step is getting it onto a page where visitors can actually fill it out.
