Validate Post size for file uploads

[tuxmason]

Greetings. I write to request help. I need my screen to display an exception or error alert if an uploaded file is larger than post_max_upload.

My screen has an input filed (type file) for selecting a document. When a file smaller than post_max_upload is uploaded, the form works as expected. When a file larger than post_max_upload is uploaded, the upload fails, the screen reloads and does not display any error message.

I have tried adding "->middleware(ValidatePostSize::class)" to my routes. I have also added "\Illuminate\Foundation\Http\Middleware\ValidatePostSize::class" to the middleware in platform.php but the problem persists.

When I try the upload code using a custom blade (which does not use any orchid components), as expected, laravel throws a PostTooLargeException.

How do I get my orchid screen to throw and catch a PostTooLargeException?

It was resolved in the Telegram discussion:

When the form is submitted, Ajax is used for a smooth reload. However, if an exception is returned in response, the behavior differs.
To make it consistent, simply add the ->rawClick() method to the submit button.

Yes, adding ->rawClick() resulted in display of the default PostTooLargeException error page.

Content Too Large

Illuminate\Http\Exceptions\PostTooLargeException

The POST data is too large.

...\vendor\laravel\framework\src\Illuminate\Http\Middleware\ValidatePostSize.php :24

The next challenge

Gracefully handling the PostTooLargeException

• Appended the following middleware declarations to config/platform.php

'middleware' => [
        'public'  => ['web', 'cache.headers:private;must_revalidate;etag',
            \Illuminate\Session\Middleware\StartSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \Illuminate\Http\Middleware\ValidatePostSize::class],
        'private' => ['web', 'platform', 'cache.headers:private;must_revalidate;etag',
            \Illuminate\Session\Middleware\StartSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \Illuminate\Http\Middleware\ValidatePostSize::class],
],

• Capture and handle the PostTooLargeException,

Added the code below to ->withExceptions in bootstrap/app.php

->withExceptions(function (Exceptions $exceptions) {
        
        $exceptions->render(function (PostTooLargeException $e, Request $request) {

            $webserver_upload_max = ((int)ini_get('upload_max_filesize'))*1024*1024;

            $message = __('The maximum upload size for files is :MaxUploadSize.', 
                ['MaxUploadSize' => Number::fileSize(bytes: $webserver_upload_max, maxPrecision: 2) ]);

            return back()->withErrors(['message' => $message]);
        });

    })->create();

• The result

Internal Server Error

ErrorException

Undefined variable $errors

...\vendor\orchid\platform\resources\views\partials\alert.blade.php :10

• This is where I get stuck.

How do I fix this?
