Validation of array in laravel

Question

I am building a small application in Laravel 5.6 where I am having an api which takes an array in format [1,2,5,90,25] I want to validate as required field in my validation rule.

I tried creating a request and validating the same as:

public function rules()
{
    return [
        'ProjectType.*'=>  'required',
    ]
}

public function messages()
{
    return [
        'projectType.*.required' => 'Project type is required',
    ];
}

But this thing is not working out, even if an empty array [] is being passed it accepts it.

How can we achieve these kind of array format

Answer 1

You must validate at the top level of the array, you may want this validation:

public function rules()
{
    return [
        'ProjectType'=>  'required|array',
        'ProjectType.*'=>  'required',
    ]
}

public function messages()
{
    return [
        'projectType.*.required' => 'Project type is required',
    ];
}
