如何使用合并替换Laravel请求中的嵌套数组值? [英] How to replace nested array value inside the Laravel request using merge?

问题描述

有一个函数可以替换请求中的输入，这称为合并.我想更改嵌套数组的值，以便可以通过 $ this-> validate方法 .. p进行验证.

There is a function to replace the input from the request which is called merge. I would like to change a value of a nested array so that it can be validated by $this->validate method..

这是 $ request-> all()

array:2 [
  "type" => "customer"
  "users" => array:1 [
      0 => array:3 [
        "name" => "eeee"
        "username" => "eeee"
        "password" => "123456"
      ]
  ]
]

如果使用forloop，如何访问和更改用户名

How do I access the username value and change it, provided I use a forloop

for($i=0; $i < count($request->users); $i++){
    // i need to access the value here
    // i have done something like $request->merge(['users'][$index]['username'] => 'xxx');
    // it doesnt work
 }

有解决方案的人吗?谢谢.

Any solution guys? Thank you.

推荐答案

您可以使用merge方法尝试以下操作:

You can try something like this using merge method:

$new_users_data = $request->input('users');

foreach ($new_user_data as &$user_data) {
    $user_data['username'] = 'new name';
}

$request->merge([
    'users' => $new_users_data,
]);

您还可以使用请求替换方法将整个输入替换为新输入.
