Laravel 5.7.13 Released

Laravel 5.7.13 was released Wednesday with some new collection methods and the ability to return an array of messages in a custom validation rule.

First, new empty collection methods were added, including whenEmpty, whenNotEmpty, unlessEmpty, and unlessNotEmpty. For example, the whenEmpty method will fire this callback on an empty collection:

<?php

use Illuminate\Support\Collection;

$collection = new Collection;

$collection->whenEmpty(function ($collection) {
    return $collection->push('adam');
});

$this->assertSame(['adam'], $collection->toArray());

The unless* behave the opposite way:

<?php

use Illuminate\Support\Collection;

$collection = new Collection;

$collection->unlessEmpty(function ($collection) {
    return $collection->push('adam');
});

$this->assertSame([], $collection->toArray());

If the collection isn’t empty, the unlessEmpty closure is called:

<?php

use Illuminate\Support\Collection;

$collection = new Collection(['user1', 'user2']);

$collection->unlessEmpty(function ($collection) {
    return $collection->push('user3');
});

$this->assertSame(['user1', 'user2, 'user3'], $collection->toArray());

Next, the ability to add an array of validation messages to custom validation rules was added. In a custom validation rule, you can return an array of messages like so:

public function message()
{
    return [
        ':attribute must be taylor',
        ':attribute must be a first name'
    ];
}

You can see the full diff between 5.7.12 and 5.7.13 on GitHub, and the full release notes below from the 5.7 changelog.
