Gravity Forms 3.0 uses imaskjs for US phone fields and text fields with an input mask. A custom script may still wait for the old jQuery plugin, call a removed method, change a default value after initialization, or reinitialize an AJAX-rendered form twice. The visible field can look correct while the submitted value fails PHP validation, strips digits, duplicates punctuation, or differs between desktop and a mobile numeric keyboard. The useful test traces raw input, mask state, serialized request, entry value, notification value, and downstream record instead of judging only the formatted field.
Use this when a Gravity Forms 3.0 form rejects a default phone number, behaves differently after paste or autofill, breaks in a popup, or relies on custom input-mask JavaScript.
Quick answer
Test the same values by typing, pasting, browser autofill, mobile keyboard, backspace, and AJAX re-render. Record the displayed value, raw input, request payload, server validation, stored entry, notification, and CRM value. Remove calls to the old jQuery mask API, initialize custom behavior through current Gravity Forms lifecycle events, and make the handler idempotent. Do not weaken server validation merely to make the visual mask pass.
Test scenarios to run
Run the same controlled fixture across these branches. Write down the expected result before testing so a surprising response is easy to identify.
| Scenario | Fixture | Expected result |
|---|
| US phone | Typed and pasted values | Same normalized digits |
| Default value | Preloaded valid number | Submits without mask drift |
| AJAX form | Validation then retry | One mask instance |
| Mobile | Autofill and numeric keyboard | No lost digits |
Diagnostic table
Use this table to connect the observed behavior to evidence and a verification step.
| Action | Evidence | Verification |
|---|
| Inventory masked fields and legacy hooks | Inventory Phone and Single Line Text fields that enable masks, their default values, dynamic population, custom formats, JavaScript hooks, and conditional containers. | Typing, paste, autofill, retry, and mobile input produce the same expected stored value. |
| Capture raw and formatted values | Capture listener and initialization counts before typing, after an AJAX page change, after validation failure, and when a popup is opened a second time. | Each rendered field has one mask instance and one set of custom handlers. |
| Remove old jQuery mask calls | Test empty, complete, incomplete, pasted, autofilled, international, extension, mobile, and accessibility keyboard paths against the same expected storage contract. | Server validation rejects incomplete values without corrupting a valid default value. |
| Add one current lifecycle initializer | Compare the DOM value, imask state, serialized POST value, PHP validation result, entry value, merge tag output, webhook payload, and CRM normalization. | Notifications, webhooks, and CRM records receive the documented normalized value. |
What to check first
- Inventory Phone and Single Line Text fields that enable masks, their default values, dynamic population, custom formats, JavaScript hooks, and conditional containers.
- Capture listener and initialization counts before typing, after an AJAX page change, after validation failure, and when a popup is opened a second time.
- Test empty, complete, incomplete, pasted, autofilled, international, extension, mobile, and accessibility keyboard paths against the same expected storage contract.
- Compare the DOM value, imask state, serialized POST value, PHP validation result, entry value, merge tag output, webhook payload, and CRM normalization.
- Update custom code to current events and selectors, add one stable initialization guard, then retest with optimization and cache enabled.
Field notes
- Write the expected result before changing anything and keep one repeatable canary fixture for the full test window.
- Record exact versions and UTC timestamps because a cache purge, scheduled action, retry, or deployment can change the evidence between tests.
- Test the real browser and downstream record, not only an admin preview or isolated API call.
- Close the task only after the public workflow, server-side record, and relevant delivery or analytics system agree.
Useful command or data shape
Adapt paths, IDs, and privacy handling to the site before running commands or storing data on production.
console.count('gf-mask-init');
const input = document.querySelector('#input_17_4');
console.table({
displayed: input?.value,
inputMode: input?.inputMode,
listenersChecked: true,
formId: 17,
fieldId: 4
});
Why this usually happens
- Legacy code expects a jQuery plugin method that no longer exists.
- The mask initializes before a dynamically populated default value arrives.
- AJAX or popup lifecycle code attaches a second mask to the same input.
- Server regex validation and browser-side normalization expect different formats.
Decision rule
Keep visual formatting and server validation as separate contracts. Release only when every supported input path stores the intended canonical value and repeated renders create one mask instance.
Production verification checklist
- Typing, paste, autofill, retry, and mobile input produce the same expected stored value.
- Each rendered field has one mask instance and one set of custom handlers.
- Server validation rejects incomplete values without corrupting a valid default value.
- Notifications, webhooks, and CRM records receive the documented normalized value.
Safe fix order
Use a sequence that makes each result easy to prove. Stop when new evidence changes the scope or owner of the problem.
- Inventory masked fields and legacy hooks
- Capture raw and formatted values
- Remove old jQuery mask calls
- Add one current lifecycle initializer
- Retest server and downstream normalization
Mistakes to avoid
- Changing production code, form fields, webhook endpoints, cache settings, or security limits before preserving the failing fixture and current configuration.
- Treating one clean dashboard status as proof even though the browser, PHP process, database, delivery provider, and downstream record have not been reconciled.
- Testing with a different form, role, locale, order state, entry shape, plugin version, or cache state than the workflow users actually reach.
- Leaving debug logs, temporary endpoints, broad permissions, copied secrets, or test notifications active after the verification window closes.
Questions teams ask during testing
Can I test this directly on production?
Read-only checks can be appropriate when access is controlled and output is redacted. Make a backup first, use a named canary record, test state-changing work on staging, define rollback, and schedule any production change for a monitored window.
How do I avoid a false positive?
Match the exact version, request path, form or order ID, role, locale, cache state, and integration path. Repeat the same fixture before and after the change, then compare the saved evidence rather than relying on memory.
What evidence should I keep?
Keep the UTC time, site and plugin versions, fixture ID, expected result, actual result, relevant logs, configuration snapshot, change made, rollback point, and final verification. Remove passwords, tokens, payment details, and personal data.
When should I bring in a specialist?
Escalate when checkout, payments, lead capture, security, customer email, accessibility, or several integrations are affected, or when the safest next step is unclear. A concise evidence packet reduces diagnosis time.
What to tell the client or owner
Give the owner a short evidence packet with the affected workflow, exact versions, UTC test time, fixture ID, expected and actual result, logs, change, rollback point, final result, owner, and next review date. Redact credentials and personal data before sharing it.
