Question

我只是尝试使用php将数据从android代码插入到mysql数据库，但代码没有做任何事情。

register.php：

<?php

// array for JSON response
$response = array();

 // check for required fields

if (isset($_POST['n'])) 
{  

$name = $_POST['n'];
$address = $_POST['add']; 
//$age = $_POST['age'];
$phone = $_POST['phone'];
$email = $_POST['e'];  
$bloodgroup = $_POST['bloodgroup'];  


// include db connect class
require_once __DIR__ . '/db_connect.php';

// connecting to db
$db = new DB_CONNECT();

   // mysql inserting a new row
$result = mysql_query("Insert into bloodtb(Name,Address,Phone,Email,Bloodgroup) values

('$name','$address','$phone','$email','$bloodgroup')");

// 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);
} 
?>

register.java：

public class register extends Activity
{

EditText name,address,bg,ph,email,age;
Button register;


private ProgressDialog pDialog;
int flag=0;
JSONParser jsonParser = new JSONParser();
private static String url = "http://192.168.43.41/phpfiles/register.php";
private static final String TAG_SUCCESS = "success";

protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.register);

    name=(EditText)findViewById(R.id.etname);
   // age=(EditText)findViewById(R.id.etage);
    address=(EditText)findViewById(R.id.etadd);
    bg=(EditText)findViewById(R.id.etbg);
    email=(EditText)findViewById(R.id.etemail);
    ph=(EditText)findViewById(R.id.etphone);


    register=(Button)findViewById(R.id.btnreg);

    register.setOnClickListener(new View.OnClickListener()
    {
        public void onClick(View view){

         new Thread(new Runnable() {
              @Override
              public void run() {
                  new loginAccess().execute();                  }
          });

        }
    });

   } 

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

    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(register.this);
        pDialog.setMessage("Registering..");
        pDialog.setIndeterminate(false);
        pDialog.setCancelable(true);
        pDialog.show();
    }
    @Override
    protected String doInBackground(String... arg0) {
        List<NameValuePair> params = new ArrayList<NameValuePair>();

        String n=name.getText().toString();
        //String a=age.getText().toString();
        String add=address.getText().toString();
        String e=email.getText().toString();
        String phone=ph.getText().toString();
        String bloodgroup=bg.getText().toString();


        params.add(new BasicNameValuePair("n", n));
       // params.add(new BasicNameValuePair("age", a));
        params.add(new BasicNameValuePair("add",add));
        params.add(new BasicNameValuePair("phone",phone));
        params.add(new BasicNameValuePair("e", e));
        params.add(new BasicNameValuePair("bloodgroup",bloodgroup));

        JSONObject json = jsonParser.makeHttpRequest(url,"POST", params);

        Log.d("Create Response", json.toString());

        try {
            int success = json.getInt(TAG_SUCCESS);
            if (success == 1)
            {
                flag=0;
                //Intent i = new Intent(getApplicationContext(),search.class);
                /*i.putExtra("mobile_number",number);
                i.putExtra("password",pwd);*/
                //startActivity(i);
                finish();
            }
            else
            {
                // failed to Sign in
               flag=1;
            }
        } catch (JSONException ex) {
            ex.printStackTrace();
        }
        return null;
    }
    protected void onPostExecute(String file_url) {
        pDialog.dismiss();
        if(flag==1)
            Toast.makeText(register.this,"Please Enter Correct informations", Toast.LENGTH_LONG).show();

    }

}


}

日志cat中没有错误，但仍未将任何内容插入数据库..请帮助。

您没有启动该线程，因此您的代码根本不会执行

new Thread(new Runnable() 
{
     @Override
     public void run() 
     {
          new loginAccess().execute();                  
     }
 }).start();

AsyncTask也在不同的线程上执行，所以即使在代码下面也应该执行任务

new loginAccess().execute();

Android代码不会使用PHP插入到mysql数据库中
