Required Field Not Working?
Your required fields should prevent submission without data, but they're either too strict or not working at all.

Our free scan loads your site in a real browser and checks for this exact issue.
Required field validation is supposed to ensure you receive complete, useful submissions. When it fails, you either get incomplete data that's useless for follow-up, or valid submissions get blocked because validation is too aggressive.
Both failures cost you leads. Broken validation lets garbage through. Overly strict validation stops real people from contacting you.
The tricky part is that required field issues often go unnoticed. You might be receiving incomplete submissions without realizing required fields aren't enforcing, or losing leads who couldn't figure out what they did wrong.
Common Symptoms
- • Form submits even when required fields are empty
- • Required fields don't show error messages
- • Valid data is rejected as invalid
- • Asterisks appear but fields aren't actually required
- • Error messages don't clear when field is corrected
- • Different behavior across browsers
Why This Happens
1. Required Attribute Missing
The HTML5 required attribute might not be set on fields you thought were required. Visual indicators like asterisks don't enforce anything—the attribute must be present.
2. JavaScript Bypassing HTML Validation
If form submission is handled by JavaScript that calls event.preventDefault() without its own validation, HTML5 required validation never triggers.
3. novalidate Attribute on Form
The form element might have novalidate attribute, which disables all HTML5 validation. This is sometimes added intentionally for custom validation that then fails to work.
4. Custom Validation Not Running
If you rely on JavaScript validation instead of HTML5, and that script has errors or doesn't load, there's no validation at all.
5. Validation Regex Too Strict
Regular expression patterns for email, phone, or other fields might reject valid input. International formats, special characters, or unusual but valid entries get blocked.
Quick Diagnostic Checklist
Try these steps to narrow down the problem:
-
1
Inspect field attributes
Right-click fields and verify they have the required attribute if they should be required.
-
2
Check for novalidate on form
Inspect the form element for novalidate attribute which disables HTML5 validation.
-
3
Test with empty required fields
Try submitting with required fields empty. If it submits, validation isn't working.
-
4
Check console for JavaScript errors
Errors might prevent custom validation from running.
-
5
Test validation patterns
If using pattern attribute, test that valid data matches the pattern.
-
6
Verify error message elements exist
Check that containers for error messages are present in the HTML.
When to Stop Debugging Manually
Validation issues are subtle and have multiple potential sources:
- — HTML validation vs JavaScript validation conflicts
- — Server-side validation that differs from client-side
- — Browser differences in validation implementation
- — Patterns that work in testing but fail with real user input
Comprehensive testing with varied inputs is the only way to ensure validation works correctly for all users.
