Validation tutorial

You are overriding your own validation that you have set in BaseController.

This are a stand alone function, that you pass your rules directly into that array.
$this->validate([])

If wan't to use setRules() you need to runt it like this:

if($this->validation->withRequest($this->request)->run()).

Here you can see the actual code that stand alone function executes.

PHP Code:

    /**
     * A shortcut to performing validation on input data. If validation
     * is not successful, a $errors property will be set on this class.
     *
     * @param array|string $rules
     * @param array        $messages An array of custom error messages
     *
     * @return boolean
     */
    protected function validate($rules, array $messages = []): bool
    {
        $this->validator = Services::validation();

        // If you replace the $rules array with the name of the group
        if (is_string($rules))
        {
            $validation = config('Validation');

            // If the rule wasn't found in the \Config\Validation, we
            // should throw an exception so the developer can find it.
            if (! isset($validation->$rules))
            {
                throw ValidationException::forRuleNotFound($rules);
            }

            // If no error message is defined, use the error message in the Config\Validation file
            if (! $messages)
            {
                $errorName = $rules . '_errors';
                $messages  = $validation->$errorName ?? [];
            }

            $rules = $validation->$rules;
        }

        return $this->validator
            ->withRequest($this->request)
            ->setRules($rules, $messages)
            ->run();
    }
