Merge new value on Laravel array request
提问by Sebastian Corneliu V?rlan
If I have all my input values on $request->input('users')how can I merge new one?
如果我有关于$request->input('users')如何合并新的所有输入值？
Something like this:
像这样的东西：
$request->merge(['users.dob' => '2000']);
But obvious is not working.
但显然是行不通的。

First, we need to get all items that belong in that array and save temporarily.
首先，我们需要获取属于该数组的所有项目并临时保存。
For instance,
例如，
$users = $request->users;
This way, you can access a user's data like $users['name']or $users['surname'].
这样，您就可以访问用户的数据，例如$users['name']或$users['surname']。
Next, update or add whatever data you need to. For instance, like this:
接下来，更新或添加您需要的任何数据。例如，像这样：
$users['dob'] = "2000";
$users['name'] = ucwords($request->users['name']);
...
When we are done, we merge our temporary array back into $requestlike this:
完成后，我们将临时数组合并回$request如下所示：
$request->merge(['users' => $users]);

Try this:
尝试这个：
$request->request->add(['users.dob', '2000']);
It seems merge()doesn't work anymore.
好像merge()已经不行了。

Try this:
尝试这个：
$originalInput = $request->input('users');
$defaultValue = [
'dob' => 2000
];
$mergedResult = array_merge($defaultValue, $originalInput);
$request->merge([
'users' => $mergedResult
]);
If you're looking for something more elegant (read: hard way) and improve the reusability of your code, you can follow this steps:
如果您正在寻找更优雅的东西（阅读：困难的方式）并提高代码的可重用性，您可以按照以下步骤操作：
- Create a Service Provider, here we register a macro to
Requestobject.
- 创建一个服务提供者，这里我们注册一个宏到
Request对象。
php artisan make:provider RegisterMergeInputRequestMacro
- Write your provider
- 写你的提供者
<?php
namespace App\Providers;
use Illuminate\Http\Request;
use Illuminate\Support\ServiceProvider;
class RegisterMergeInputRequestMacro extends ServiceProvider
{
/**
* Register services.
*
* @return void
*/
public function register()
{
Request::macro('mergeInput', function (string $name, array $defaultValue) {
$this->merge([
$name => array_merge($defaultValue, $this->input($name))
]);
});
}
}
- Register the
ServiceProviderin yourconfig/app.phpfile:
ServiceProvider在您的config/app.php文件中注册：
return [
...
'providers' => [
...
App\Providers\RegisterMergeInputRequestMacro::class,
...
],
...
];
- Use it like a boss:
- 像老板一样使用它：
$request->mergeInput('users', [
'dob' => 2000
]);

尝试这个：
$request->request->add([

'new-field2' => 'value 2'
]);

You can try this for
你可以试试这个
public function __construct(\Illuminate\Http\Request $request)
{
$request->request->add(
['date_of_birth' => implode('-',$request->only('year', 'month', 'day'))]);
}

Try this:
尝试这个：
$data= $request->input('users');
$data['dob'] = 2000;
