使用php

Question

我有简单的JSON，如

[{
        "id": "77",
        "agent_id": "20",
        "raised_by": "C",
        "from_date": "2016-11-09",
        "to_date": "2016-11-10",
        "ConsultantInfo": {
            "user_id": "3045",
            "inquiry_id": "77"
        },
        "otherInfo": {
            "a": "test",
            "b": "testing"
        }
}]

当我点击保存按钮的时候，我需要合并一些现有的json数据，如下所示，每当我点击保存按钮时会出现新数据，所以我必须将所有数据存储到json文件中阵列。

[{
        "ConsultantInfo": {
            "user_id": "1",
            "inquiry_id": "2"
        },
        "otherInfo": {
            "a": "abc",
            "b": "xyz"
        }
}]

所以最后的结果应该是这样的：

[{
    "id": "77",
    "agent_id": "20",
    "raised_by": "C",
    "from_date": "2016-11-09",
    "to_date": "2016-11-10",
    "ConsultantInfo": [
        {
        "user_id": "3045",
        "inquiry_id": "77"
        },
        {
        "user_id": "2",
        "inquiry_id": "71"
        } 
    ],
    "otherInfo": [
      {
        "a": "test",
        "b": "testing"
      },
      {
        "a": "kk",
        "b": "dd"
      } 
    ]
}]

mycode的：

<?php

    $state_current_arr = '{ "id": "77", "agent_id": "20", "raised_by": "C", "from_date": "2016-11-09", "to_date": "2016-11-10" }';
    if(isset($_POST['savebtn'])) //save button
    {
    $jsonData = array();
    $jsonData['ConsultantInfo'] = array("user_id"=>"3045","inquiry_id"=>"77");
    $jsonData['otherInfo'] = array("a"=>"test","b"=>"testing");

    $tempArray = json_decode($state_current_arr,true);
    $tempArray = array_merge($tempArray, $jsonData);
    $jsonData_merged = json_encode($tempArray);

    echo $jsonData_merged;
    }
 ?>

您可以使用array_merge_recursive，但需要将ConsultantInfo和otherInfo修改为多维数组

试试这个：

$state_current_arr = '{ "id": "77", "agent_id": "20", "raised_by": "C", "from_date": "2016-11-09", "to_date": "2016-11-10" }';

$jsonData = array();
$jsonData['ConsultantInfo'][] = array("user_id"=>"3045","inquiry_id"=>"77");
$jsonData['otherInfo'][]      = array("a"=>"test","b"=>"testing");

$tempArray = json_decode($state_current_arr,true);

$dataRequired = array();
$dataRequired['ConsultantInfo'][] = array("user_id"=>"1","inquiry_id"=>"2");
$dataRequired['otherInfo'][]      = array("a"=>"abc","b"=>"xyz");

$jsonData_merged = array_merge_recursive($tempArray,$jsonData,$dataRequired);

var_dump($jsonData_merged);
