Elegant code to convert Laravel $validation->messages() to array of objects

Question

Usually, when validating form requests in Laravel, we can access the errors using $validation->messages(). For example:

object(Illuminate\Support\MessageBag)#184 (2) { ["messages":protected]=> array(2) { ["email"]=> array(1) { [0]=> string(40) "The email must be a valid email address." } ["password"]=> array(2) { [0]=> string(41) "The password confirmation does not match." [1]=> string(43) "The password must be at least 6 characters." } } ["format":protected]=> string(8) ":message" }.

Is there some elegant way to convert the object MessageBag to a sample array, such as:

[
object({"email" => "The email must be a valid email address."}),
object({"password" => "The password confirmation does not match."})
...
]

PS: If in the MessageBag, any field has more then one item, I would like only the first item in the resulting array of objects.

Thanks in advance.

It depends on your definition of elegant, but if you're asking if there's a single function to call on an MessageBag instance to get what you're looking for, I don't think there is. However you may be able to do it in something of a one-liner by mapping the messages stored within the bag like so: array_map(function ($item) { if (is_array($item)) { return reset($item); } return $item; }, $m->getMessages()); (In fact, because we know the messages are always an array you could remove the is_array conditional if you want to.) — alexrussell

Is it not possible to do $validation->messages()->toArray() ? You used to be able to do $validation->messages()->toJson(), so I am assuming toArray() would also work. — Jeemusu

@Evgeniy Try the toArray() method then. You can find all the methods available in the API documentation: laravel.com/api/master/Illuminate/Contracts/Support/…

I try this of course too. But some conditions from my question are not performed. I think it's impossible without any logic unfortunately :(

@Evgeniy You’re right. A field can have multiple errors, hence getting an array per key. Just use array_shift($messages) in PHP, or messages.shift() in JavaScript to get the first message for each field.

This what I get $response = []; foreach ($validator->messages() ->toArray() as $key => $value) { $obj = new \stdClass(); $obj->name = $key; $obj->message = $value[0]; array_push($response, $obj); }

@Evgeniy I really don’t know what you’re trying to show me.

Ok, something like this

$response = []; 
foreach ($validator->messages()->toArray() as $key => $value) { 
    $obj = new \stdClass(); 
    $obj->name = $key; 
    $obj->message = $value[0];

    array_push($response, $obj); 
}

It is not elegant but I do not see another way :)
