如何在 Laravel 7 中设置 required_if

$validator = Validator::make($request->all(), [
    'color_name' => 'required_with:color_code',
]);

if ($validator->fails()) {
   return  $validator->errors()->first();
}

使用它来解决问题。

对于阵列，请将您的阵列重新塑造成这个

array:2 [
  0 => array:2 [
    "color_name" => "red"
    "color_code" => "#77"
  ]
  1 => array:2 [
    "color_name" => "blue"
    "color_code" => "#88"
  ]
]


$validator = Validator::make($request->all(), [
    'color'=>'array',
    'color.*.color_name' => 'required_with:color.*.color_code',
]);
