How to get the key from a laravel form request?
提问by Rubberduck1337106092
I have an array
我有一个数组
array:2 [▼
2 => "12"
7 => "12"
]
Send from a form, I need the 2 and 7 how do i call them?
从表格发送，我需要 2 和 7 我该如何称呼它们？
The keys are id's of parts so want to. foreach get the ID and value then update something...
键是部件的 id，所以想要。foreach 获取 ID 和值，然后更新某些内容...
foreach($request->except('_token') as $part) {
/*get Key here (in this case 2 or 7) and get value here (in this case both 12)*/
}
Can somebody tell me how to do this?
有人能告诉我怎么做吗？
Thanks in advance.
提前致谢。

$data = $request->except('_token')
foreach($data as $id => $value){
echo "My id is ". $id . " And My value is ". $value;
}

If You want to access exactly one $requestkey, You can use:
如果您只想访问一个$request密钥，您可以使用：
$request->key_name
to achieve this.
为达到这个。

例子
I was sending an imagein postman like this:
我正在发送这样image的邮递员：
And I got it in Laravel's controller like this:
我在 Laravel 的控制器中得到了它，如下所示：

$image = $request->image; // this is what You need :)
// ...
}
