Validation Patterns

Email Validation

function validateEmail(email: string): boolean {
  const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
  if (!emailRegex.test(email)) {
    return false;
  }
  return true;
}

// With error message
function validateEmailWithError(email: string): { valid: boolean; error: string } {
  const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
  if (!email.trim()) {
    return { valid: false, error: 'Email is required' };
  }
  if (!emailRegex.test(email)) {
    return { valid: false, error: 'Please enter a valid email address' };
  }
  return { valid: true, error: '' };
}

Phone Validation (Indian Mobile)

function validatePhone(phone: string): boolean {
  // Indian mobile: 10 digits, starts with 6-9
  const phoneRegex = /^[6-9]\d{9}$/;
  return phoneRegex.test(phone);
}

// With detailed errors
function validatePhoneWithError(phone: string): { valid: boolean; error: string } {
  if (!phone.trim()) {
    return { valid: false, error: 'Phone number is required' };
  }
  if (!/^\d+$/.test(phone)) {
    return { valid: false, error: 'Phone must contain only digits' };
  }
  if (phone.length !== 10) {
    return { valid: false, error: 'Phone must be exactly 10 digits' };
  }
  if (!/^[6-9]/.test(phone)) {
    return { valid: false, error: 'Phone must start with 6, 7, 8, or 9' };
  }
  return { valid: true, error: '' };
}

Name Validation

function validateName(name: string): boolean {
  return name.trim().length >= 2;
}

// With error message
function validateNameWithError(name: string): { valid: boolean; error: string } {
  const trimmed = name.trim();
  if (!trimmed) {
    return { valid: false, error: 'Name is required' };
  }
  if (trimmed.length < 2) {
    return { valid: false, error: 'Name must be at least 2 characters' };
  }
  if (trimmed.length > 100) {
    return { valid: false, error: 'Name is too long (max 100 characters)' };
  }
  return { valid: true, error: '' };
}

Required Field Validation

function validateRequired(value: string, fieldName: string): { valid: boolean; error: string } {
  if (!value.trim()) {
    return { valid: false, error: `${fieldName} is required` };
  }
  return { valid: true, error: '' };
}

Dropdown/Select Validation

function validateSelect(value: string, fieldName: string): { valid: boolean; error: string } {
  if (!value || value === '') {
    return { valid: false, error: `Please select a ${fieldName}` };
  }
  return { valid: true, error: '' };
}

Multi-Select Validation

function validateMultiSelect(values: string[], fieldName: string): { valid: boolean; error: string } {
  if (values.length === 0) {
    return { valid: false, error: `Please select at least one ${fieldName}` };
  }
  return { valid: true, error: '' };
}

    isSubmitting = true;

    try {
      // 4. Create submission object with timestamp
      const submission = {
        ...formData,
        timestamp: Date.now()
      };

      // 5. Update local store (optional, for immediate UI feedback)
      addSubmission(submission);

      // 6. Save to Firestore
      const docId = await addToFirestore(submission);
      console.log('✅ Saved with ID:', docId);

      // 7. Show success message

      // 9. Optional: Redirect after delay
      setTimeout(() => {
        goto('/thank-you');
      }, 2000);

      // 10. Handle errors
      console.error('❌ Submission error:', error);
      errorMessage = 'Something went wrong. Please try again.';
    } finally {
      // 11. Clear loading state
