使用php在mysql数据库中插入记录

我在android上做一个调查项目，关于登录（这部分有效）和插入数据这部分无效的是问卷调查，当调查人员登录到应用程序时，有一个调查要做，在这个项目中，我从5个问题开始，回答是或否作为原型，他必须回答这些问题，并且在单击save按钮时，必须将这些问题添加到mysql数据库中。但这不起作用（日志如下） 下面是课堂调查问卷。java：

public class Questionnaire extends Activity implements LocationListener {
// Progress Dialog
    private ProgressDialog pDialog;
//latitude et longitude
    private LocationManager lm;
    Location location;
    double longitude = 0;
    double latitude = 0;
    private double altitude;
    private float accuracy;
    int i;
    JSONParser jsonParser = new JSONParser();
    Button enregistrer;
    EditText zone;
    RadioGroup mRadioGroup1, mRadioGroup2, mRadioGroup3, mRadioGroup4, mRadioGroup5;
    RadioButton b1, b2, b3, b4, b5;
// url to create new product
    private static String url_insertion = "http://10.0.2.2/android/insertion.php";
// JSON Node names
    private static final String TAG_SUCCESS = "success";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.questions);
        Bundle params = getIntent().getExtras();
        i = params.getInt("compteur");
        i++;

        // Edit zone text
        EditText zone1 = (EditText) findViewById(R.appreciation.zone);

        // edit latitude longitude
        latitude = location.getLatitude();
        longitude = location.getLongitude();

        // edit radiogroup
        mRadioGroup1 = (RadioGroup) findViewById(R.appreciation.rep1);
        mRadioGroup2 = (RadioGroup) findViewById(R.appreciation.rep2);
        mRadioGroup3 = (RadioGroup) findViewById(R.appreciation.rep3);
        mRadioGroup4 = (RadioGroup) findViewById(R.appreciation.rep4);
        mRadioGroup5 = (RadioGroup) findViewById(R.appreciation.rep5);

        //edit radio button
        b1 = (RadioButton) findViewById(mRadioGroup1.getCheckedRadioButtonId());
        b2 = (RadioButton) findViewById(mRadioGroup2.getCheckedRadioButtonId());
        b3 = (RadioButton) findViewById(mRadioGroup3.getCheckedRadioButtonId());
        b4 = (RadioButton) findViewById(mRadioGroup4.getCheckedRadioButtonId());
        b5 = (RadioButton) findViewById(mRadioGroup5.getCheckedRadioButtonId());

        // Create button
        Button enregistrer = (Button) findViewById(R.appreciation.enregistrer);

        // button click event
        enregistrer.setOnClickListener(new OnClickListener() {

            public void onClick(View view) {
                new InsertAppreciation().execute();
            }
        });
    }

    class InsertAppreciation extends AsyncTask<String, String, String> {

        /**
         * Before starting background thread Show Progress Dialog
         * */
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            pDialog = new ProgressDialog(Questionnaire.this);
            pDialog.setMessage("Creating Product..");
            pDialog.setIndeterminate(false);
            pDialog.setCancelable(true);
            pDialog.show();
        }

        /**
         * Creating appreciation
         * */
        protected String doInBackground(String... args) {
            String zone1 = zone.getText().toString();
            //  String latitude = String.valueOf(latitude).toString();
            //  String longitude = String.valueOf(longitude).toString();
            String rep1 = b1.getText().toString();
            String rep2 = b2.getText().toString();
            String rep3 = b3.getText().toString();
            String rep4 = b4.getText().toString();
            String rep5 = b5.getText().toString();

            // Building Parameters
            List<NameValuePair> params = new ArrayList<NameValuePair>();
            params.add(new BasicNameValuePair("zone", zone1));
            //  params.add(new BasicNameValuePair("latitude", latitude));
            //   params.add(new BasicNameValuePair("longitude", longitude));
            params.add(new BasicNameValuePair("rep1", rep1));
            params.add(new BasicNameValuePair("rep2", rep2));
            params.add(new BasicNameValuePair("rep3", rep3));
            params.add(new BasicNameValuePair("rep4", rep4));
            params.add(new BasicNameValuePair("rep5", rep5));

            // getting JSON Object
            // Note that create product url accepts POST method
            JSONObject json = jsonParser.makeHttpRequest(url_insertion,
                    "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 appreciation
                    Toast.makeText(getBaseContext(), "Successful insertion", Toast.LENGTH_SHORT).show();
                    if (i < 5) {
                        Intent intent1 = new Intent(Questionnaire.this, Questionnaire.class);
                        intent1.putExtra("compteur", i);
                        startActivity(intent1);
                    } else {
                        Intent intent2 = new Intent(Questionnaire.this, Endsurvey.class);
                        startActivity(intent2);
                    }

                } else {
                    // failed to create appreciation
                    Toast.makeText(getBaseContext(), "failed insertion", Toast.LENGTH_SHORT).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();

        }
    }
}

以下是php文件：

    <?php
    //turn off error reporting
     error_reporting(E_ALL ^ E_NOTICE ^ E_WARNING);

    //Create fields for the database
    //server, username, password, database

    $dbhost = "localhost";
    $dbuser = "root";
    $dbpass = "";
    $dbdb = "survey";

    //connect to mySQL
    $connect = mysql_connect($dbhost, $dbuser, $dbpass) or die("connection error");

    //Select the database
    mysql_select_db($dbdb)or die("database selection error");

    //Retrieve the login details via POST
    $zone = $_POST['zone'];
    $latitude = $_POST['latitude'];
    $longitude = $_POST['longitude'];
    $rep1 = $_POST['rep1'];
    $rep2 = $_POST['rep2'];
    $rep3 = $_POST['rep3'];
    $rep4 = $_POST['rep4'];
    $rep5 = $_POST['rep5'];

    // mysql inserting a new row
    $result = mysql_query("INSERT INTO appreciation(id, zone, latitude, longitude,                    rep1, rep2, rep3, rep4, rep5) VALUES('', '$zone1', '', '', '$rep1', '$rep2', '$rep3',  '$rep4', '$rep5' )");



    // check if row inserted or not
    if ($result) {
    // successfully inserted into database
    $response["success"] = 1;
    $response["message"] = "Product 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);
    //close the connection
    mysql_close();


         }



          ?>

首先，正如其他人在评论中所说，请查看PDO，因为您的数据库交互非常不安全

您提供的异常跟踪表明，
问卷调查
活动的
onCreate
方法中发生了未捕获（开始使用）异常。我预计（请通过调试进行检查）当您第二次查看意图包中的
compteur
时（您将从
inventory
转到
inventory
活动），会抛出错误

我可以看到，当您启动intent时，您正在将一个对象放入bundle中，但是在处理它之前，您没有检查它是否为null

Unable to open stack trace file '/data/anr/traces.txt': Permission denied

您是否在清单xml文件中添加了从sd卡读取的权限

<uses-permission  android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>


第1步：不要使用
mysql\u query
，而是花很短的时间来加快
mysqli
或PDO的速度。您发布的这段代码充满了SQL注入漏洞，一次恶意查询就可以摧毁整个应用程序。这是PHP问题还是Java问题？你已经发布了Java堆栈跟踪和一些随机（和可怕的）PHP代码，但没有就问题的具体性质提供任何指导。谢谢你的建议，我不知道我是android新手，我想这是Java问题，但我也发布了PHP文件，谁知道呢！，我贴了日志，但我不知道到底是什么问题？感谢您的帮助只是一个建议，如果您想关闭错误报告，请这样做：
error\u reporting（0）
您使用哪个版本的android？（因此，有人可以在ActivityThread.java:2496查看正在发生的事情）
<uses-permission  android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
