📝 Walkthrough

The controller now passes the form object to the failed-submission checker, which records a failed message when present. The JavaScript now inserts a form-level response message only when that message is truthy.

Changes: Failed submission handling

Layer / File(s)	Summary
Record and display failed messages `classes/controllers/FrmEntriesAJAXSubmitController.php`, `js/formidable.js`	The controller passes the form object to the checker. When a failed-message text is present, the checker records it and clears the response content. The JavaScript inserts the form-level response message only when it is truthy.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Bug fix

Suggested reviewers: njonesfermoy2011-rgb

Merge Risk: 🟡 Moderate · up to 02890

Sites that configure an empty failed-submission message can lose the confirmation content of AJAX submissions. Add an empty-message guard before merging.

Approve. The fix does what it says: a duplicate AJAX submit now shows the "already submitted" message inside the form. One non-blocking note on an empty failed message (inline). Pro's companion change is #6846.

Live check (preview env, Lite on this PR and Pro on #6846, AJAX form, same value submitted twice):

Base: the second submit leaves the form with no message at all (no error summary, no duplicate text).
This PR: the form shows <div role="alert" data-frm-error-summary="1"><div id="failed_error">We're sorry. It looks like you've already submitted that.</div></div> at the top.
First, non-duplicate submit on this PR still shows the normal "Thanks!" success message.

js/formidable.min.js is regenerated and contains the new if(response.error_message) guard. Not covered: I did not click through other form-level error keys (spam, etc.), and no PHPUnit test was added or run.

Non-blocking: an empty Failed/Duplicate Entry message now renders an empty red alert box (see inline).

franky-the-going-merry · 2026-10-15T12:54:26Z

-		if ( str_contains( $response['content'], $frm_settings->failed_msg ) ) {
-			$response['errors']['failed'] = $frm_settings->failed_msg;
-			$response['content']          = '';
+		if ( ! str_contains( $response['content'], $frm_settings->failed_msg ) ) {


With the Failed/Duplicate Entry message set to an empty string, str_contains( $content, '' ) is always true in PHP 8, so this branch runs on every AJAX submit, including successful ones. I reproduced it: on base the success message is silently dropped and the form reappears (already wrong). On this PR the form now also shows an empty red role="alert" box (<div id="failed_error"></div>).

Treat an empty message as "nothing to detect" and leave the response alone:

Suggested change

if ( ! str_contains( $response['content'], $frm_settings->failed_msg ) ) {

if ( '' === $frm_settings->failed_msg || ! str_contains( $response['content'], $frm_settings->failed_msg ) ) {

Use the explicit '' comparison (not empty()), so a message of '0' is still searched. CodeRabbit raised the same point. Pro's copy of this function in #6846 needs the same change.

franky-the-going-merry

Approve (re-review at bcc81a7). The new commit adds the guard I suggested last round: '' === $frm_settings->failed_msg || ! str_contains(...) returns the response untouched when the Failed/Duplicate Entry message is empty. A '0' message still gets searched, since the check is an exact '' compare.

Live check (private preview env, Lite on this PR, an AJAX form with the Failed/Duplicate Entry message set to empty, a unique value submitted once):

Previous head 0289027: the form re-renders with an empty red alert box and no success message (<div id="failed_error"></div>):
This head bcc81a7: the normal success message shows, no empty alert:
Non-empty message, same value twice: the second submit shows the duplicate message in the form's error summary, as in my first review.

Only the empty-message and non-empty duplicate paths were exercised again; php -l is clean. No PHPUnit test was added or run, and most CI jobs show as skipped. Pro companion #6846 is unchanged and was not re-checked.
