Laravel validate array of objects

Question

I wonder if its possible to validate a array of objects in Laravel? I have built a form looking like a excell page using vue, so the user can edit many rows that later gets uploaded.

The data that I wish to validate when posting to my controller looks like this:

rows[
0 {
  title: "my title",
  post: "my post text"
},
1 {
 title: "my title",
  post: "my post text"
},
2 {
 title: "my title",
  post: "my post text"
}
]

So for example how can I add a required rule to each input?

Answer 1

You can use array validation of Laravel.

eg.

$validator = Validator::make($request->all(), [
    'row.*.title' => 'required',
    'row.*.post' => 'required',
]);

Answer 2

The approved answer works if your posting an array, however to take it a step further, I am needing to save multiple arrays. While that approach would work if I make two separate endpoints, what if I want to save everything inside one DB::transaction?

Viola:

// POST:
{
    "array1": [
        { "key1": "string", "key2": 1 },
        { "key1": "string", "key2": 0 }
    ],
    "array2": [
        { "key3": "string", "key4": 1 },
        { "key3": "string", "key4": 0 }
    ]
}

// SERVER:
$this->validate($request, [
    'array1' => 'present|array',
    'array2' => 'present|array',
    'array1.*.key1' => 'required|string',
    'array1.*.key2' => 'required|integer',
    'array2.*.key3' => 'required|string',
    'array2.*.key4' => 'required|integer'
]);

DB::transaction(function() use($request) {
    foreach($request['array1'] as $x){
        // ...do stuff here
    };
});

Note: 'present|array' accepts empty arrays whereas 'required|array' would reject them.
