Dynamically assign validation parameters in Respect Validations

Question

My initial question was how to do dynamic chaining of Respect validations.

My implementation was like following,

    $validator = v::notEmpty();

    foreach ($validations as $validation) {
        $variable = (string)$validation['validatorName'];
        if (sizeof($validation['params']) > 0) {
            $validator = $validator->$variable($validation['params'][0],$validation['params'][1]);
        } else {
            $validator = $validator->$variable();
        }
   }

When a validation has parameters the way that I have done was wrong because if there are more than 2 parameters this fails . So what I wanted was to dynamically assign parameters according to how many parameters that each validation accepts. It's like dynamically chaining the validations.

Can you please improve your question by fixing grammar, showing with code what you want to do and also the validators you want to use? — Davide Pastore, Apr 02 '18 at 17:40

I'm not sure if that's a good idea, at the first sight. However I don't know the problem you're trying to fix, if you really need to create validators from an array, you could use call_user_func() or call_user_func_array().

Something like:

$validator = v::notEmpty();
foreach ($validations as $validation) {
    call_user_func_array(
        [$validator, $validation['validatorName']],
        $validation['params']
    );
}
