How to add validation custom messages with array items rules when validating array in Laravel?

Question

I've custom validation code:

$this->validate($request, [
    'array' => 'required|array|max:100',
    'array.*' => 'required|string|distinct|min:3'
], [
    'array.max' => 'Array can't have more :max items',
]);

Here how I can add cusom message with array items rule?

For example: 'array.item.min' => 'Array items length can't be greater :min charackters'

Example laravel default validation error message for array items:

{
  message: "The given data was invalid."
}

errors: {
  array.3: ["The array.3 must be at least 3 characters."]
}

array.3: ["The array.3 must be at least 3 characters."]

0: "The array.3 must be at least 3 characters."
message: "The given data was invalid."

How I can replace this validation message with my single message for array items?

can you provide more code so i can understand better

I'm not sure, can you try array.*.min?

You can try adding custom messages on each element when the form is submitted. Here's the sample code

$customMessages['array.max'] = "Array can't have more :max items";

foreach ($request->get('array') as $key => $value) {
    $customMessages['array.' . $key . '.min'] = "Array items length can't be greater :min characters";
}

$this->validate($request, [
    'array' => 'required|array|max:100',
    'array.*' => 'required|string|distinct|min:3'
], $customMessages);

If you want to show the error in your view, you can do this:

@if ($errors->has('array.0'))
    {{ $errors->first('array.0') }}
@endif

If you have foreach in the view

@if ($errors->has('array.'.$index))
    {{ $errors->first('array.'.$index) }}
@endif

For example I will return error message and use it with javascript. Example generated message in js: skills.2: Array(1). Here array name is skills.2. Error with 2 item of array. Can you say your mean about showing error messages?
