Validation issue on multiple file upload

[muradmustafayev]

In validation getFile() returns NULL in CI4\system\Validation\FileRules.php if send multiple file to validate. Should check if multiple or single upload
Same issue on other validation methods where is used getFile()

public function max_size(string $blank = null, string $params, array $data): bool
	{
		// Grab the file name off the top of the $params
		// after we split it.
		$params = explode(',', $params);
		$name   = array_shift($params);
		$file = $this->request->getFile($name); // returns NULL but files exist in $this->request. Should check if multiple or single upload
		if (is_null($file))
		{
			return false;
		}
		return $params[0] >= $file->getSize() / 1024;
	}

My Controller method

public function upload()
    {
        $validation =  \Config\Services::validation();
        $validation->setRules([
                'avatars' => 'max_size[avatars,2048]|mime_in[avatars,image/jpeg]|ext_in[avatars,jpeg,jpg]',
            ]
        );

        $validation->withRequest($this->request)->run();
        dd($validation->getErrors());
    }

HTML code

<?= form_open_multipart('admin/post/upload') ?>
        <input type="file" name="avatars[]" multiple>
        <input type="submit">
    <?= form_close() ?>

Another problematic thing is empty spaces in validation rules. I mean:
mime_in[avatars, image/jpeg, application/pdf] - not working
mime_in[avatars,image/jpeg,application/pdf] - works

It'd be handy if remove spaces with str_replace or regex.
original code - $params = explode(',', $params); (file: CI4\system\Validation\FileRules.php)

Spaces are not allowed in validation rules strings- that is not a bug.

If you feel strongly about this, bring it up as an issue on its own, or raise it on the CI4 feature requests subforum.
