Better docmentation / example for unnamed values / items

[th-lange]

Requirement:

I want to validate an array of objects, like:

[
    {
        "foo": "foo1",
        "bar": "bar1",
        "baz": "baz1"
    },
    {
        "foo": "foo2",
        "bar": "bar2",
        "baz": "baz2"
    },
    {
        "foo": "foo3",
        "bar": "bar3",
        "baz": "baz3"
    }
]

So I tried this:

        $validator = new Validator();
        $rules = RulesBuilder::create()
            ->rule('collection', RulesBuilder::create()
                ->field('foo', 'required')
                ->field('bar', 'required')
                ->field('baz', 'required')
                ->build()
            )->build();

But I get the error:
array_shift() expects parameter 1 to be array, string given
vendor/philiplb/valdi/src/Valdi/Validator.php:131

It would be nice, to get an example on how to validate "unnamed" collections.

Hi,

is this covered by the A More Complex Example? There is a field "postings" which is an array of objects.

I got it now:
Using a collection also requires a "nested" element. But still no luck...

        $validator = new Validator();
        $rules = RulesBuilder::create()
            ->rule('collection', $validator, RulesBuilder::create()
                ->rule('nested', $validator, RulesBuilder::create()
                    ->field('foo', 'required')
                    ->field('bar', 'required')
                    ->field('baz', 'required')
                    ->build()
                )
                ->build()
            )
            ->build();

I can work with named elements... Yeah. But it will just not work with "unnamed" sequences for me.
The above example works, when i use:

        $rules = RulesBuilder::create()
            ->field('namedItem', 'collection', $validator, RulesBuilder::create()
                ->rule('nested', $validator, RulesBuilder::create()
                     ...
