Multiple array validation in laravel

Question

I have 3 types of data to validate

data in group
single data
single and data in group combined

This validation works for single data

$validator = Validator::make($request->all(), [
    'tests.*.finding' => 'required',//works for single test
]);

Data sample for above

["tests"=>
                [
                    0 => ["finding"=>""]
                ],
                [
                    1 => ["finding"=>""]
                ]
            ]

And this validation works for data in group

$validator = Validator::make($request->all(), [
    'tests.*.*.finding' => 'required',//works for group
]);

Data sample for above

  ["tests"=>
                    [
                        "A" =>[
                            [
                                0 => ["finding"=>""]
                            ],
                            [
                                1 => ["finding"=>""]
                            ]
                        ],
                        "B" =>[
                            [
                                0 => ["finding"=>""]
                            ],
                            [
                                1 => ["finding"=>""]
                            ]
                        ]
                    ]
                ]

How to validate for single and data in group combined

Combined Data sample

 ["tests"=>
                    [
                        "A" =>[
                            [
                                0 => ["finding"=>""]
                            ],
                            [
                                1 => ["finding"=>""]
                            ]
                        ]
                    ],
                    [
                        0 => ["finding"=>""]
                    ],
                    [
                        1 => ["finding"=>""]
                    ]
                ]

Please help me to fix this, as 1st scenario always gives error for scenario second and vice versa.

Probably can't do this with the validation rules. You can create a custom validator or split the Combined Data into the previous 2 examples if its easier. — thefallen

This is the solution,Laravel provided sometimes rule to manage existence of element and then only proceed to check next rule.

So final validation rule is.

 $validator = Validator::make($request->all(), [
 'tests.*.*.finding' => 'sometimes|required',//works for group
 'tests.*.finding' => 'sometimes|required',//works for single test
 ]);

Doc for this : https://laravel.com/docs/5.4/validation#conditionally-adding-rules

You can following code to fix the validation data.

$customFieldValidation = ["test_id" => 'required|numeric',
        "test_two.id" => 'required|numeric',        
        ]);     
  $this->setRules ( $customFieldValidation );  
  $customeAttributes = [
  "test_three.*.id" => 'Test Three ' // custom message
  ];
  $this->setCustomAttributes ($customeAttributes);
  $this->_validate ();

I hope it's helpful to you.
