위는 자바 코드이구요 ,
아래는 PHP 코드입니다.
<?php
/*
* Following code will create a new product row
* All product details are read from HTTP Post Request
*/
// array for JSON response
$response = array();
// check for required fields
if (isset($_POST['name']) && isset($_POST['price'])) {
$name = $_POST['name'];
$price = $_POST['price'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
// mysql inserting a new row
$result = mysql_query("select name,price from products where name='$name' and price='$price'");
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Login Success";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Login Failed";
// echoing JSON response
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}
?>
Login 버튼을 눌러 실행을 해보면, 바로 close가 되어 버리는데 어떤증상인가요 ㅜㅜ.
도와주세요
