Summary of Changes
Hello @westonruter, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly enhances the reliability of detecting login form submissions by moving from a brittle ID-based detection to a more resilient URL-based comparison. This ensures that the JavaScript-enabled cookie is consistently set, even when login flows are modified by plugins or custom configurations, thereby improving the overall robustness of the system.
Highlights
- Enhanced Login Form Detection: The logic for detecting login form submissions has been improved to be more robust. Instead of relying solely on the form's
idattribute (e.g.,loginform), the system now compares the form'sactionURL against the canonical WordPress login post URL (wp-login.php). This change addresses scenarios where plugins or custom setups might alter the form's ID or introduce interstitial login screens, ensuring consistent detection. - Dynamic Login URL Provision: The canonical WordPress login post URL is now dynamically passed from the PHP backend (
includes/bfcache-opt-in.php) to the JavaScript frontend (js/detect-scripting-enabled-at-login.js). This ensures the JavaScript has the correct URL for comparison, making the detection mechanism more reliable across different site configurations.

Code Review
This pull request improves the robustness of detecting login form submissions by replacing a check for a specific form ID with a check on the form's action URL. This is a solid improvement. I have provided one suggestion to further enhance this robustness by considering the formaction attribute on submit buttons, which can override the form's primary action.

Code Review
This pull request improves the robustness of detecting login form submissions by switching from a hardcoded form ID check to comparing the form's action URL. I've identified an issue in the new JavaScript helper function where it doesn't account for all types of submit elements, which could lead to incorrect behavior in some cases. A fix is suggested.

Code Review
This pull request improves the robustness of detecting login form submissions by replacing a check for a specific form ID with a more reliable comparison of the form's action URL against a value provided by the backend. This is a solid improvement. The new logic correctly handles cases where a submit button's formaction attribute overrides the form's default action. I have one suggestion to make the JavaScript code more concise and readable.
| const contentAttribute = event.submitter.getAttribute( 'formaction' ); | ||
| if ( | ||
| typeof contentAttribute === 'string' && | ||
| contentAttribute.trim() !== '' | ||
| ) { | ||
| return event.submitter.formAction; | ||
| } |

The logic to check for a valid formaction attribute can be made more concise and readable. getAttribute returns null (which is falsy) if the attribute is not present, and an empty string is also falsy. You can leverage this to simplify the conditional check.
const contentAttribute = event.submitter.getAttribute( 'formaction' );
if ( contentAttribute && contentAttribute.trim() ) {
return event.submitter.formAction;
}
