Message translations not working with craft.formie.renderForm

[romainpoirier]

Describe the bug

Describe the bug:

I'm using Formie 3.0.12 and attempting to translate messages for a form rendered with {{ craft.formie.renderForm('donation') }}.

I created a translation file at /translations/fr/formie.php, containing all the keys from vendor/verbb/formie/src/translations/en/formie.php (following the documentation). However, these translations are not being applied to the error messages.

Note: The Craft site’s language is configured as French (fr), and I have confirmed that other translations (e.g., for templates and fields) are working as expected.

Expected behavior:

The error messages should be translated into French based on the keys in the /translations/fr/formie.php file.

Actual behavior:

The messages remain in English, even though the corresponding French translations are defined in the translation file.

Steps to reproduce

1. Render the form with {{ craft.formie.renderForm('donation') }}
2. Add a validation error on the form (e.g., leave a required field empty)
3. Observe if the error messages are displayed in French as per the formie.php translation file.

Form settings

• Multi-page form: No
• Submission Method: Ajax
• Client-side Validation: Yes
• Custom Form Templates: No

What's your static translation string? Using the following is working for me:

'{attribute} cannot be blank.' => '{attribute} cannot be blank (in French).',

I was using a copy of one of the translation files (en/formie.php):

<?php

return [
  //
  // Email Messages
  //
  'formie_failed_notification_heading' => 'When an email notification fails to send:',
  'formie_failed_notification_subject' => 'Email notification failed to send for form "{{ form.title }}" on {{ siteName }}.',
  'formie_failed_notification_body' => "An email notification for the form “{{ form.title }}” has failed to send.\n\n" .
    "The error response was recorded: {{ emailResponse | json_encode }}.\n\n" .
    "To review it please log into your control panel.\n\n" .
    "{{ submission.cpEditUrl }}",

  '"{label}" should contain at most {max, number} {max, plural, one{character} other{characters}}.' => '"{label}" should contain at most {max, number} {max, plural, one{character} other{characters}}.',
  '(GDPR) {text}' => '(GDPR) {text}',
  ...
];

I assumed it included all the necessary translations for forms and planned to use it as a starting point. However, I noticed that the key {attribute} cannot be blank. is indeed not present in this file.

After adding it, I can confirm that this key is translated correctly.

Is there a registry of required translation keys? Or should I simply use another language file as a base (e.g., nl/formie.php)?

Thanks!

Apologies for that missing from the English file! We automate adding strings to that file, so I'll see if there's just been a mishap to including it. That should certainly be the central registry of translations strings to work from.

Yep, looks like a few were just plainly missed.
