Converting Laravel validation message dot syntax into array

Question

I'am using Laravel on server side. Let's imagine our controller receive two fields url [string] and data [array with index head]. We can validate data and customize errors messages with

$this->validate($request, [

    'url' => 'required',
    'data.head' => 'required',

], [

    'url.required' => 'The :attribute field is required',
    'data.head.required' => 'The :attribute field is required',
]);

If validation fails, Laravel send back response with json data

{
    "url": ["The url field is required"],
    "data.head": ["The data.head field is required"]
}

How we can convert response data to send json, as below?

{
    "url": ["The url field is required"],
    "data": {
        "head": ["The data.head field is required"]
    }
}

In javascript

Loop on errors

error: function (errors) {
    $.each(errors['responseJSON']['errors'], function (index, error) {
        var object = {};
        element = dotToArray(index);
        object[index] = error[0];
        validator.showErrors(object);
    });
}

convert in dot notation into array notation. i.e abc.1.xyz into abc[1][xyz]

function dotToArray(str) {
    var output = '';
    var chucks = str.split('.');
    if(chucks.length > 1){
        for(i = 0; i < chucks.length; i++){
            if(i == 0){
                output = chucks[i];
            }else{
                output += '['+chucks[i]+']';
            }
        }
    }else{
        output = chucks[0];
    }

    return output
}

On the PHP side, you can use the undot function of the Collection class:

collect($errors->toArray())->undot()

Laravel has an helper called array_set that transform a dot based notation to array.

I don't know how you send the errors via ajax, but you should be able to do something like that:

$errors = [];
foreach ($validator->errors()->all() as $key => $value) {
  array_set($errors, $key, $value);
}

Edit: But apparently, you should be able to not use the dot notation by Specifying Custom Messages In Language Files like this example:

'custom' => [
    'email' => [
        'required' => 'We need to know your e-mail address!',
    ],
],

I'am confusing. Why Laravel did not do converting dot syntax in response automatically?

Clément Baconnier Over a year ago

I edited, my answer. I'm guessing, Laravel keeps the format that you specified. At least, that make sense to me, but don't see the point of using dot notation afterward.

Thank you for answear, of course I know about custom messages in separate files, but it is not decide my problem. I will use messages transformation before sending back.

Clément Baconnier Over a year ago

Sorry, what I try to meant is, If you use the array notation, laravel should return the errors messages as array.

I don't know if it's still a valid question but to create a custom validation using dot notation in laravel, you can specify the array like this in your validation.php

'custom' => [
        'parent' => [
            'children' => [
                'required' => 'custom message here'
            ]
        ]

This will be the parent.children property.

see ya.

key = key.replace(/\./g, '[') + Array(key.split('.').length).join(']');
