在列出项目之前,我有一个应用程序的功能来创建一个新数据,其中包含来自另一个活动的唯一ID。唯一的数据是" sid"。我使用PHP连接到phpmyadmin数据库。
<?php
// array for JSON response
$response = array();
// check for required fields
if (isset($_POST['foodName']) && isset($_POST['foodPrice']) && isset($_POST['foodType']) && isset($_POST['sid']) {
$foodName = $_POST['foodName'];
$foodPrice = $_POST['foodPrice'];
$foodType = $_POST['foodType'];
$sid = $_POST['sid'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
// mysql inserting a new row
$result = mysql_query("INSERT INTO food(foodName, foodPrice, foodType, sid) VALUES('$foodName', '$foodPrice', '$foodType', '$sid')");
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Food successfully created.";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
// echoing JSON response
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}
?>
这是从其他活动接收数据的意图:
Intent i = getIntent();
// getting product id (sid) from intent
sid = i.getStringExtra(TAG_SID);
最后,我在课堂上执行此操作:
protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("foodName", getFoodName));
params.add(new BasicNameValuePair("foodPrice", getFoodPrice));
params.add(new BasicNameValuePair("foodType", getFoodType));
params.add(new BasicNameValuePair("sid", sid));
有什么地方我做错了吗?在我的桌子上,我有这个&#34; sid&#34;太
答案 0 :(得分:0)
你必须做以下事情 在第一个活动中
Intent intent = new Intent(getBaseContext(), SignoutActivity.class);
intent.putExtra("sid", VALUE);
startActivity(intent);
在第二项活动中
Bundle extras = getIntent().getExtras();
if (extras != null) {
String value = extras.getString("sid");
}
