Input field validation for forms: A checklist from a designer to a dev with love

FORM VALIDATION IS TAKEN FOR GRANTED AND YET IT COULD MAKE OR BREAK THE QUALITY OF WORK YOU PUSH TO STAGING OR PRODUCTION.
I have created a quick checklist to help your form validation be as sleek as Kim Kardashian's bun.

Start here

  1. Identify Required Fields: Clearly mark all mandatory fields (asterisk, bold text)

  2. Define Validation Rules: Document specific requirements for each field (length, format, etc.)

*Validation Checks *

  1. Length: Minimum and maximum characters allowed (e.g., username 6-20 characters)

  2. Data Type: Numbers only, letters only, email format, etc. (use regular expressions if needed)

  3. Range: For numbers (e.g., age between 18-65)

  4. Selection: Ensure dropdowns or radio buttons have a valid selection

*Error Messages *

  1. Clarity: Use clear and concise language (e.g., "Username must be 6-20 characters")

  2. Specificity: Indicate the exact error (e.g., "Invalid email format").

  3. User-friendliness: Avoid technical jargon (e.g., "Please enter a valid email" instead of "Invalid email syntax").

  4. Placement: Display error messages near the associated field.

Additional Tips

  1. Real-time feedback: Consider inline validation as users type (e.g., color change for invalid input).

  2. Positive reinforcement: Acknowledge successful validation (e.g., green checkmark).

  3. Testing: Thoroughly test all validation scenarios.
