Androidエミュレーター3.1を使用してmysqlに挿入しようとしていますが、挿入できない問題があり、logcatでエラーが発生するので、誰かが私のコードを助けてくれます.mysqlに空のデータを挿入する面白い部分.
PHP
mysql_select_db("properties", $con);
$sql="INSERT INTO customer(C_Name, C_Surname, C_ID, C_Address, C_Email, C_CellNumber, C_UserName, C_Password)
VALUES('$_POST[C_Name]','$_POST[C_Surname]','$_POST[C_ID]','$_POST[C_Address]','$_POST[C_Email]',
'$_POST[C_CellNumber]','$_POST[C_UserName]','$_POST[C_Password]')";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
//echo "1 record added";
echo json_encode($sql);
mysql_close($con);
そして私の活動
protected String doInBackground(String... args) {
String name = input_Name.getText().toString();
String surname = input_Surname.getText().toString();
String ID = input_ID.getText().toString();
String Address = input_Address.getText().toString();
String Emial = input_Email.getText().toString();
String CellNumber = input_CellNumber.getText().toString();
String Username = input_UserName.getText().toString();
String Pasword = input_Password.getText().toString();
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("name",name));
params.add(new BasicNameValuePair("surname",surname));
params.add(new BasicNameValuePair("ID",ID));
params.add(new BasicNameValuePair("Address",Address));
params.add(new BasicNameValuePair("Emial",Emial));
params.add(new BasicNameValuePair("CellNumber",CellNumber));
params.add(new BasicNameValuePair("Username",Username));
params.add(new BasicNameValuePair("Pasword",Pasword));
// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_product,
"POST", params);
// check log cat fro response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created product
Toast.makeText(RegisterUsers.this,"Customer has been Registered",Toast.LENGTH_LONG).show();
// closing this screen
// finish();
} else {
// failed to create product
Toast.makeText(RegisterUsers.this,"Error",Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String file_url) {
// dismiss the dialog once done
pDialog.dismiss();
}
}
エラーをグーグルで検索しようとしましたが、見つかりませんでした。このコードを試すのに約3時間かかるため、何をすべきかを知る必要があります。ログの猫のエラー
