Laravel broken translator (affects validation messages)-CodePudding

I have a problem with validation in Laravel. It used to work properly but now it does not. I do not know when the problem started.

The problem appears using the Validator class or a custom request file.

For example:

$validator = Validator::make($request->all(), [
    'username' => 'required',
]);

If username is missing will produce an error bag containing the following error text:

validation.required

which is useless as far as validation feedback goes. If another field does not satisfy the minimum length, the error bag will contain:

validation.required
validation.min

Instead it should use the descriptions in the lang/en/validation.php file: 'The :attribute field is required.' i.e. 'The username field is required.'

It seems like the lang file is completely ignored. I checked it, and it contains a valid array. I don't know how to troubleshoot this. Can you please help?

I print out the errors as follows:

@if ($errors->any())
  <div >
    <ul>
      @foreach ($errors->all() as $message)
        <li>{{ $message }}</li>
      @endforeach
    </ul>
  </div>
@endif

Example of message bag as seen from the debugger:

UPDATE: I found the original cause of the problem.

# vendor/laravel/framework/src/Illuminate/Translation/Translator.php 
public function get( ..

this function fails to retrieve the translated line. Because the load() function fails to load the contents of lang/en/validation.php Because it's looking for it in the wrong path (/resources/lang/). Because there exists a /resource/lang folder, which was put there by a third party package (outdated, that was the path in laravel 8).

CodePudding user response：

The problem was in fact with the translation subsystem.

It's been caused by a third party plugin which created a /resources/lang folder. This was the lang folder location in Laravel 8, and it still takes precedence over the new location /lang. But the necessary files were not there and the translation failed without raising any exception (!!!).

Removing the /resources/lang folder resolved my issue.
