如何从yii2中的多个数组中获取post值 [英] how to get post value from multiple array in yii2

问题描述

我想在 yii2 中获取 post 数组的值，我有这样的数组

I want to get value of post array in yii2, I have array like this

[Brand] => Array
                (
                    [name] => Array
                        (
                            [0] => testing
                            [1] => jkhkjhjkhjk
                        )

                    [tagline] => Array
                        (
                            [0] => kjhjkh
                            [1] => 
                        )

                    [meta_keyword] => Array
                        (
                            [0] => 
                            [1] => 
                        )

                    [sort_order] => 
                    [image] => brand/1452498338552.jpg
                    [status] => 
                )

        )

我尝试使用以下函数获取价值，但无法获取.

I tried to get value with below function, but i am unable to get it.

$request = Yii::$app->request;

$request->post('Brand[name][0]');

如何获取名称数组的值?我不想像 $_POST['Brand']['name'][0] 那样使用它，我只需要使用 yii2 函数

How can i get value of name array ? I don't want to use it like $_POST['Brand']['name'][0], I need to use only yii2 function

推荐答案

尝试使用 ArrayHelper 类

$var = ArrayHelper::getValue($request->post(), 'Brand.name.0');

$request->post() 方法的工作方式，它只是从 $_POST 返回一个值，所以用法是:

The way $request->post() method works, it just returns to you a value from $_POST, so usage is:

$brand = $request->post('Brand'); // now $brand variable contains $_POST['Brand']
$var = $brand['name'][0]
