My form has the same input field multiple times. My form field is as follows:
<input type='text' name='items[]'>
<input type='text' name='items[]'>
<input type='text' name='items[]'>
And request contains ($request['items'):
array:1 [▼
"items" => array:3 [▼
0 => "item one"
1 => "item two"
2 => "item three"
]
]
I want atleast one of the items to be filled. My current validation in the controller is
$validator = Validator::make($request->all(),[
'items.*' => 'required|array|size:1'
]);
It does not work. I tried with combination of size, required, nullable. Nothing works.

Knowing you are using the latest version of Laravel, I really suggest looking into Form Request feature. That way you can decouple validation from your controller keeping it much cleaner.
Anyways as the answer above me suggested, it should be sufficient for you to go with:
'items' => 'required|array'

In fact, it's enough to use:
$validator = Validator::make($request->all(),[
'items' => 'required|array'
]);
The changes made:
items
instead of items.*
- you want to set rule of general items, if you use items.*
it means you apply rule to each sent element of array separatelysize:1
because it would mean you want to have exactly one element sent (and you want at least one). You don't need it at all because you have required
rule. You can read documentation for required rule and you can read in there that empty array would case that required
rule will fail, so this required
rule for array makes that array should have at least 1 element, so you don't need min:1
or size:1

You can use a custom rule with a closure.
https://laravel.com/docs/5.7/validation#custom-validation-rules
To check if an array has all null values check it with array_filter which returns false if they're all null.
So something like...
$request->validate([
'items' => [
// $attribute = 'items', $value = items array, $fail = error message as string
function($attribute, $value, $fail) {
if (!array_filter($value)) {
$fail($attribute.' is empty.');
}
},
]
]);
This will set the error message: 'items is empty."

You should try this:
$validator = $request->validate([
"items" => "required|array|min:3",
"items.*" => "required|string|distinct|min:3",
]);

You can check it like this:
$validator = Validator::make($request->all(), [
"items" => "required|array|min:1",
"items.*" => "required|string|distinct|min:1",
]);

Just Do it normally as you always do:
$validator = Validator::make($request->all(),[
'items' => 'required'
]);
