Which data do I send wrong? - php

Question

My incoming JSON object:
{
"date": "2018-10-10",
"fiche": 1,
"fiche_type": 2,
"description": "test",
"project_code": "444",
"invoces":
[
{
"id": 1,
"description": "Ol",
"amount": 300,
"type": "debit"
},
{
"id": 2,
"type" :"credit",
"description": "Ol2",
"amount": 200
}
]
}
Validation rules are:
public function rules()
{
return [
'date' => 'required|date_format:Y-m-d',
'fiche' => 'required|integer',
'fiche_type' => 'required|integer',
'description' => 'string',
'project_code' => 'string',
'invoices' => 'required|array',
'invoices.id' => 'required|integer',
'invoices.description' => 'string',
'invoices.amount' => 'required|numeric',
'invoices.type' => 'required|string',
];
}
I always get a common error as: Wrong data validation

Answer 1

If you check closely to your validation rules, specifically:
return [
// ...
'invoices' => 'required|array',
'invoices.id' => 'required|integer', // <---
'invoices.description' => 'string', // <---
'invoices.amount' => 'required|numeric', // <---
'invoices.type' => 'required|string', // <---
];
With that setup, something like this should pass the validation (at least that part):
$invoices = [
'id' => 123,
'description' => 'a description',
'amount' => 123,
'type' => 'a type',
];
but that is not what you want.. you need to actually validate an array of items (array) with that structure:
$invoices = [
[
'id' => 123,
'description' => 'a description',
'amount' => 123,
'type' => 'a type',
],
[
'id' => 345,
'description' => 'another description',
'amount' => 156,
'type' => 'another type',
],
];
So.. what is the problem?
Well, before the item keys, you need to access the key of the item itself, but given that this rules will apply for every item in the array you need to make use of a wildcard. As the documentation says:
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',
]);
Likewise, you may use the * character when specifying your validation
messages in your language files, making it a breeze to use a single
validation message for array based fields:
'custom' => [
'person.*.email' => [
'unique' => 'Each person must have a unique e-mail address',
] ],
So in your case:
return [
// ...
'invoices' => 'required|array',
'invoices.*.id' => 'required|integer', // <---
'invoices.*.description' => 'string', // <---
'invoices.*.amount' => 'required|numeric', // <---
'invoices.*.type' => 'required|string', // <---
];
Check the Validation Arrays section of the documentation.
