如何从Respect \ Validation获取验证错误消息？

Question

I have been using Respect Validation for form Validation

$app->post('/', function () use ($app) {

    $validator  = v::key('name', v::string()->notEmpty())
                    ->key('email', v::email()->notEmpty())
                    ->key('message', v::string()->notEmpty());

    $errors = array();

    try{
        $validator->assert($_POST);
    } catch (\InvalidArgumentException $e) {
        $errors = $e->findMessages(array(
            'notEmpty'     => '{{name}} is required',
            'email'        => '{{name}} must be a valid email'
        ));
    }

    if ($validator->validate($_POST)) {
        // do stuff

        $app->redirect('/');

    } else {

        $app->render('index.php', array('field_errors' => array_values($errors)));

    }
});

looping through array_values($errors) would give me:

"" is required
email must be a valid email

I need something like:

name is required
email must be a valid email
message is required

How should it be done using Respect Validation

Answer 1

The messages are there but your findMessages lookup is searching for notEmpty and email.

What you actually have in $errors are :

Array
(
    [0] => 
    [1] => email must be a valid email
)

$errors[0] is your lookup for notEmpty which wasn't found.
$errors[1] is your lookup for email which was found.

If you change it to look for the fields in question name, email and message:

    $errors = $e->findMessages(array(
        'name'         => '{{name}} is required',
        'email'        => '{{name}} must be a valid email',
        'message'      => '{{name}} is required'
    ));

Then you will get the desired results :

Array
(
    [0] => name is required
    [1] => email must be a valid email
    [2] => message is required
)

Excuse the delayed response I purely stumbled on this by chance, you will find much quicker results if requesting support from the official Respect\Validation issue tracker instead. This would also be the ideal platform for any suggestions you may have for improvements to help avoid the problems you've experienced. You will find the Respect team eager, friendly and always willing to help.

nJoy!
