我正在尝试使用 android emulator 3.1 插入 mysql，但我的问题我无法插入，它在 logcat 中给了我错误，有人可以帮我请在这里我的代码。有趣的部分是将空数据插入我的 mysql。

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);

还有我的活动

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();
        }

    }

我试图用谷歌搜索错误但没有找到它。我只需要知道该怎么做，因为它尝试了这个代码将近 3 个小时。我的日志猫错误

你需要改变这个

params.add(new BasicNameValuePair("name",name)); 
params.add(new BasicNameValuePair("surname",surname));

并且它必须与像这样的php相同

params.add(new BasicNameValuePair("C_Name",name)); 
params.add(new BasicNameValuePair("C_Surname",surname));
