不能從數據庫插入到本地主機使用php

我想存儲數據庫中存在的本地主機，我的android和php代碼似乎工作正常，但它不寫入數據到數據庫。不能從數據庫插入到本地主機使用php

這裏是我的Android doInBackground

@Override 
    protected String doInBackground(String... params) { 
     String type= params[0]; 
     String name; 
     String user_name; 
     String user_phone; 
     String user_address; 
     String password; 
     String login_url = "http://192.168.1.5/Sandbox/signup.php"; 
     String register_url = "http://192.168.1.5/Sandbox/Register.php"; 

     if (type.equals("login")){ 
      try { 
       Log.d("inside", "doInBackground: "); 
       password = params[2]; 
       name= params[1]; 
       URL url = new URL(login_url); 
       Log.d("middle", "doInBackground: "); 
       HttpURLConnection http = (HttpURLConnection) url.openConnection(); 
       http.setRequestMethod("POST"); 
       http.setDoOutput(true); 
       http.setDoInput(true); 
       Log.d("middle", "doInBackground: "); 
       OutputStream outputstream = http.getOutputStream(); 
       BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputstream, "UTF-8")); 
       String post_data = URLEncoder.encode("name"+"UTF-8")+"="+URLEncoder.encode(name+"UTF-8")+"&"+URLEncoder.encode("password"+"UTF-8")+"="+URLEncoder.encode(password+"UTF-8"); 
       Log.d("middle", "doInBackground: "); 
       bufferedWriter.write(post_data); 
       bufferedWriter.flush(); 
       bufferedWriter.close(); 
       outputstream.close(); 

       InputStream inputstream = http.getInputStream(); 
       BufferedReader bufferedreader = new BufferedReader(new InputStreamReader(inputstream,"iso-8859-1")); 
       result=""; 
       String line=""; 

       while ((line=bufferedreader.readLine())!=null){ 
        result+=line; 
       } 
       bufferedreader.close(); 
       inputstream.close(); 
       http.disconnect(); 
       inputstream.close(); 

       Log.d("leaving","doInBackground: "); 
       return "Registration Successful"; 


      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     }

這裏是我的PHP文件

<html lang="en"> 
<title>LOGIN</title> 
<body> 
<?php 
require "Conn.php"; 



    $name= $_POST["name"]; 
    $password = $_POST["password"]; 

$mysql_qry="insert into user_table values('$name','$password')"; 


if (mysqli_query ($con,$mysql_qry)){ 
echo "Insert Success"; 

} 
else{ 
    echo "ERROR!".mysqli_error($con); 
    } 

    $con->close(); 
?> 

</body> 
</html>

敬酒消息說像未定義指數

和數據庫更新到無文本空白框。

127.0.0.1/Sandbox/signup.php應該是本地主機URL從模擬器 – Rasel

仍然沒有成功 – Developer

嘗試刪除html標籤只留下PHP：

<?php 
    require "Conn.php"; 

    $name= $_POST["name"]; 
    $password = $_POST["password"]; 

    $mysql_qry="insert into user_table values('$name','$password')" 

    if (mysqli_query ($con,$mysql_qry)){ 
    echo "Insert Success"; 

    } 
    else{ 
     echo "ERROR!".mysqli_error($con); 
    } 

$con->close(); 
?>

容易受到SQL注入！使用準備查詢..！ –

我不是PHP專家，我只是更新了他的代碼 –

可以請給我參考準備查詢和SQL注入，傑西K丹尼 – Developer
