它有Android應用程序向數據庫添加數據, 但是當你在阿拉伯數據輸入時, 顯示「?????」 。 我嘗試了所有的方法。如何從android中插入阿拉伯數據到mysql數據庫
文件的config.inc.php:
<?php
$username = "*****";
$password = "****";
$host = "*****";
$dbname = "*****";
$options = array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8');
try
{
$db = new PDO("mysql:host={$host};dbname={$dbname};charset=utf8", $username, $password, $options);
mysql_set_charset('utf8');
}
catch(PDOException $ex)
{
die("Failed to connect to the database: " . $ex->getMessage());
}
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
if(function_exists('get_magic_quotes_gpc') && get_magic_quotes_gpc())
{
function undo_magic_quotes_gpc(&$array)
{
foreach($array as &$value)
{
if(is_array($value))
{
undo_magic_quotes_gpc($value);
}
else
{
$value = stripslashes($value);
}
}
}
undo_magic_quotes_gpc($_POST);
undo_magic_quotes_gpc($_GET);
undo_magic_quotes_gpc($_COOKIE);
}
?>
添加文件:
<?php
require("config.inc.php");
$query = "INSERT INTO news ( news_date, news_title, news_body) VALUES (:news_date, :news_title, :news_body) ";
$query_params = array(
':news_date' => $_POST['news_date'],
':news_title' => $_POST['news_title'],
':news_body' => $_POST['news_body']
);
try
{
$stmt = $db->prepare($query);
$result = $stmt->execute($query_params);
}
catch (PDOException $ex)
{
$response["success"] = 0;
$response["message"] = "Database Error. Couldn't add News!";
die(json_encode($response));
}
$response["success"] = 1;
$response["message"] = "News Successfully Added!";
echo json_encode($response);
?>
在Android項目: 的Java文件:
public class addnews extends Dialog {
private Activity mActivity;
private EditText mNewsTitleET;
private EditText mNewsET;
private Button mPublishBtn;
public String username;
JSONParser jsonParser = new JSONParser();
private String ADD_URL =
"http://yazanyazan3.esy.es/newssite/addnews.php";
public addnews(Activity mActivity)
{
super(mActivity);
this.mActivity = mActivity;
}
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_addnews);
mNewsTitleET = (EditText) findViewById(R.id.title_news);
mNewsET = (EditText) findViewById(R.id.news_box);
mPublishBtn = (Button) findViewById(R.id.publish_btn);
Bundle use =getIntent().getExtras();
username = use.getString("name");
mPublishBtn.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View view)
{
attempAdding();
}
});
}
private void attempAdding()
{
if (!mNewsTitleET.getText().toString().equals("") &&
!mNewsET.getText().toString().equals(""))
{
new AddNewsTask().execute();
}
else
{
Toast.makeText(mActivity.getApplicationContext(),
"All fields are requires", Toast.LENGTH_LONG).show();
}
}
public Intent getIntent() {
return mActivity.getIntent();
}
private class AddNewsTask extends AsyncTask<Void, Void, Boolean>
{
private ProgressDialog mProgressDialog;
private JSONObject jsonObjectResult = null;
private String error;
@Override
protected void onPreExecute()
{
super.onPreExecute();
mProgressDialog = ProgressDialog.show(addnews.this.getContext(),
"Processing...", "Adding new news", false, false);
}
@Override
protected Boolean doInBackground(Void... params)
{
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
Date date = new Date();
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("news_user",username));
pairs.add(new BasicNameValuePair("news_date", dateFormat.format(date).toString()));
pairs.add(new BasicNameValuePair("news_title", mNewsTitleET.getText().toString()));
pairs.add(new BasicNameValuePair("news_body", mNewsET.getText().toString()));
jsonObjectResult = jsonParser.makehttprequest(ADD_URL+"?user="+username+"", pairs);
if (jsonObjectResult == null)
{
error = "Error in the connection";
return false;
}
try
{
if (jsonObjectResult.getInt("success") == 1)
{
error = jsonObjectResult.getString("message");
return true;
}
else
error = jsonObjectResult.getString("message");
}
catch (Exception ex)
{
}
return false;
}
@Override
protected void onPostExecute(Boolean aBoolean)
{
super.onPostExecute(aBoolean);
mProgressDialog.dismiss();
Toast.makeText(mActivity.getApplicationContext(), error, Toast.LENGTH_LONG).show();
dismiss();
}
} }
在數據庫中,我選擇utf8。 並嘗試所有的解決方案沒有奏效。 請幫忙。
嘗試在添加文件中添加一個靜態文本到數據庫中(不要從請求中讀取它),這樣你就可以將問題分成兩部分,你可以看到問題是從android客戶端到php服務器還是從php服務器到數據庫。 – Soosh
請問,你可以編輯我的代碼在文件中增加 我希望你幫助我我失去了希望。 – yazan
