Javascript 将多个json项传递给php

嗨，我希望能和上诉人钛合金公司合作。我正在尝试从应用程序向数据库添加多个项目。我正在使用php并传递一个json对象

以下是我的js代码：

var username = "testUser";

$.createBox_按钮Rapper.addEventListener（'click'，函数（e）{

}))； $.index.open（）

以下是php：

<?php
$data = isset($_POST['data']) ? $_POST['data']: "";//brings in string
// {
//    "boxName" = boxName;
//    "picturePath_post" = testPath;
//    "pin_post" = 9133;
//    "private_post" = 1;
//    "username_post" = testUser;
//  }
$items = explode(";", $data);
for( $i = 0 ; $i < count($items) ; $i++ ){
    $start = strpos($items[$i],' = ');
    $string = substr($items[$i], $start);
    $string = substr($string, 3);
    $items[$i] = $string;
}
$boxName = $items[0]; //getting error here
$picPath = $items[1];
$pin = $items[2];
$private = $items[3];
$username = $items[4];
$username = contentCheck($username);
if($username != ""){
    $boxName = contentCheck($boxName);
    $picPath = contentCheck($picPath);
    $private = contentCheck($private);
    $pin = contentCheck($pin);
    $code = genCode();//generate unique code
    $lastDate = date("Y-m-d");
    $con = mysqli_connect("***","***","***","***");
    mysqli_query($con, "INSERT INTO ( code, title, owner, picturePath, rep, users, private, lastDate, creationDate) VALUES ( '$code','$boxName','$username','$picPath',0,0,$private,'$lastDate','$lastDate')");
    echo '{"results":[{"and":"success"}]}';
}else{
    //return false and get the app user to enter their username and password
    echo '{"results":[{"and":"error"}]}';
}
function contentCheck($data){
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    return $data;
}

您需要使用：

您的错误是…？进行json_解码（$data）；然后以数组的形式访问数据。与爆炸和手动元素狩猎相比，这太容易了。
