Advanced Form Features
Field Validation
Ensure users enter correct data by setting validation rules:
- Required fields: Mark essential fields that must be completed
- Format checks: Validate emails, phone numbers, dates
- Custom patterns: Use regular expressions for complex validation
Calculations
Automate math in your forms:
- Simple sums: Total invoice amounts or survey scores
- Conditional math: Apply discounts only if certain boxes are checked
- Date math: Calculate days between dates
Example: Invoice Form Calculation
Create an invoice that automatically calculates:
- Quantity × Unit Price = Line Total
- Sum of all Line Totals = Subtotal
- Subtotal × Tax Rate = Tax Amount
- Subtotal + Tax = Total Due
Conditional Logic
Show/hide fields based on user selections:
- Only show "Company Name" if "Business Customer" is checked
- Reveal additional questions when "Other" is selected
- Display different fields based on country selection
Form Design Best Practices
- Logical flow: Group related fields together with clear section headers
- Mobile-friendly: Test on phones and tablets (50% of form completions are mobile)
- Accessibility: Add alt text for screen readers and ensure tab order is logical
- Visual hierarchy: Use shading and borders to distinguish sections
- Instructions: Include helper text for complex fields

Options for distributing your fillable PDF forms:
- Email attachment: Simple but requires manual collection
