There is a request.How I can validate it? I trying with foreach, but i does not work. Thanks.
The request:

'date_of_show' => '2019-01-01',
'comment' => 'Nice flat',

I tried this, but it does not work (of course... :))
public function rules()
{
$rules = [];
foreach ($this['show_data'] as $key => $item) {
$rules["show_data[$key]['buyer_search_property_id']"] = 'required';
$rules["show_data[$key]['date_of_show']"] = 'required|date';
$rules["show_data[$key]['comment']"] = 'required';
}
return $rules;
}

Answer 1

This is from laravel documentation:
You may also validate each element of an array. For example, to validate that each e-mail in a given array input field is unique, you may do the following:
$validator = Validator::make($request->all(), [
'person.*.email' => 'email|unique:users',
'person.*.first_name' => 'required_with:person.*.last_name',
]);

Answer 2

You can validate array in laravel easily like this:
public function rules()
{
return [
"show_data.*.buyer_search_propery_id" => "required",
"show_data.*.date_of_show" => "required|date",
"show_data.*.comment" => "required",
];
}
if you want your method to work, do this:
public function rules()
{
$rules = [];
foreach ($this['show_data'] as $key => $item) {
$rules["show_data.$key.buyer_search_property_id"] = 'required';
$rules["show_data.key.date_of_show"] = 'required|date';
$rules["show_data.$key.comment"] = 'required';
}
return $rules;
}
just remove the inner square brackets and the quotes and add dots to the indices, so change $rules["show_data[$key]['date_of_show']"] to $rules["show_data.$key.date_of_show"]

$data['show_data'] = [
0 => [
'buyer_search_property_id' => 1,
'date_of_show' => '2019-01-01',
'comment' => 'Nice flat',
],
1 => [
'buyer_search_property_id' => 2,
'date_of_show' => '2019-01-31',
'comment' => 'Too small',
],
];
$rules = [
'show_data.*.buyer_search_property_id' => 'required',
'show_data.*.date_of_show' => 'required|date',
'show_data.*.comment' => 'required',
];
$validator = Validator::make($data, $rules);
Note asteriks at rules. With this you don't need a foreach loop. And it looks and feels a lot cleaner.
