[英]How to insert json array into mysql database
问题描述
Hi I'm trying to insert the json array into my MySQL database.
您好我正在尝试将 json 数组插入到我的 MySQL 数据库中。 I'm passing the data form my iphone there i have converted the data into json format and I'm passing the data to my server using the url its not inserting into my server.我正在从我的 iphone 传递数据，我已经将数据转换为 json 格式，并且我正在使用未插入到我的服务器的 url 将数据传递到我的服务器。
This is my json data.这是我的 json 数据。
[{"name":"0","phone":"dsf","city":"sdfsdf","email":"dsf"},{"name":"13123123","phone":"sdfsdfdsfsd","city":"sdfsf","email":"13123123"}]
This is my Php code.这是我的 PHP 代码。
<?php
$json = file_get_contents('php://input');
$obj = json_decode($data,true);
//Database Connection
require_once 'db.php';
/* insert data into DB */
foreach($obj as $item) {
mysql_query("INSERT INTO `database name`.`table name` (name, phone, city, email)
VALUES ('".$item['name']."', '".$item['phone']."', '".$item['city']."', '".$item['email']."')");
}
//database connection close
mysql_close($con);
//}
?>
My database connection code.我的数据库连接代码。
<?php
//ENTER YOUR DATABASE CONNECTION INFO BELOW:
$hostname="localhost";
$database="dbname";
$username="username";
$password="password";
//DO NOT EDIT BELOW THIS LINE
$link = mysql_connect($hostname, $username, $password);
mysql_select_db($database) or die('Could not select database');
?>

$json = file_get_contents('php://input');
$obj = json_decode($json,true);
I think you are passing the wrong variable.我认为你传递了错误的变量。 You should pass $json in json_decode as shown above.如上所示，您应该在json_decode传递$json 。

You are missing JSON source file.您缺少 JSON 源文件。 Create a JSON file then assign it to var data:创建一个 JSON 文件，然后将其分配给 var 数据：
<?php
require_once('dbconnect.php');
// reading json file
$json = file_get_contents('userdata.json');
//converting json object to php associative array
$data = json_decode($json, true);
// processing the array of objects
foreach ($data as $user) {
$firstname = $user['firstname'];
$lastname = $user['lastname'];
$gender = $user['firstname'];
$username = $user['username'];
// preparing statement for insert query
$st = mysqli_prepare($connection, 'INSERT INTO users(firstname, lastname, gender, username) VALUES (?, ?, ?, ?)');
// bind variables to insert query params
mysqli_stmt_bind_param($st, 'ssss', $firstname, $lastname, $gender, $username);
// executing insert query
mysqli_stmt_execute($st);
}
?>

There is no such variable as $data .没有$data这样的变量。 Try尝试
$obj = json_decode($json,true);
Rest looks fine.休息看起来不错。 If the error still persists, enable error_reporting .如果错误仍然存在，请启用error_reporting 。
