我想将ListView
中的数据插入MySQL
,但列的插入值出错了,
详情:
我有这样的布局:
|--------------------|
|<id> TextView |
| * * * |
|--------------------|
|<id> TextView |
| * * * * |
|--------------------|
|<id> TextView |
| * * * * * |
|--------------------|
然后我要插入的数据库列看起来像:
|----|-------|
| ID | Nilai |
|----|-------|
| 1 | 3 |
| 2 | 4 |
| 3 | 5 |
|====|=======|
但是为什么当按下按钮时插入的数据是错误的?所有id column
值都是&#34; 0&#34;,而nilai column
是不明确的
我做错了吗?
我用来插入的代码是:
Button onClick :
int size = adapter3.getCount();
StringBuilder b = new StringBuilder();
JSONArray jArray = new JSONArray();
for (int i=0;i<size;i++){
id = String.valueOf(adapter3.getItem(i).getId());
nilai = String.valueOf(adapter3.getItem(i).getRatingStar());
new PostDataTOServer().execute();
}
PostDataTOServer class :
protected Void doInBackground(Void... arg0) {
postDataParams= new HashMap<>();
postDataParams.put("id", id);
postDataParams.put("nilai", nilai);
String path = "<MY URL>";
response= service.ServerData(path,postDataParams);
try {
JSONObject json = new JSONObject(response);
//Get Values from JSONobject
System.out.println("success=" + json.get("success"));
success = json.getInt("success");
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
insert2.php
<?php
include 'dbconfig.php';
$con = new mysqli($servername, $username, $password, $dbname);
if (!$con) {
die("Connection failed: " . mysqli_connect_error());
}
$id=$_POST["id"];
$nilai=$_POST["nilai"];
$success=0;
$sql = "INSERT INTO nilai_3 (id, nilai)
VALUES ('$id','$nilai')";
if(mysqli_query($con, $sql))
{
$success=1;
}
$response["success"]=$success;
die(json_encode($response));
mysql_close($con);
?>
