在數據庫中使用ajax/jquery插入facebook電影列表

這是我的程序，它可以很好地工作並正確地獲得用戶的興趣，即電影列表。現在我想插入到數據庫中，所以我寫了ajax調用來做到這一點，在數據庫中使用ajax/jquery插入facebook電影列表

有人可以告訴我它有什麼問題，它不會給出錯誤，但也不會插入到表中。

我張貼的數據movies_db.php

的index.php

     <button id="fb-auth">Login</button> 
     <div id="loader" style="display:none"> 
      <img src="ajax-loader.gif" alt="loading" />

     <div id="user-info"></div> 
     <br /> 
     <div id="debug"></div> 
    </body> 
</html>

movies_db.php 這部分是正確的，我相信

<?php 

$con =mysqli_connect('127.0.0.1:3306', 'root', 'root', 'test'); 
if (mysqli_connect_errno()) { 
    echo "Failed to connect to MySQL: ".mysqli_connect_error(); 
} 

foreach($_POST['myd'] as $elem){ 
    echo $elem['name']; 
    echo $elem['id']; 
    echo '<br/>'; 

    $ID=$elem['id']; 
    $Name=$elem['name']; 

    $sql = "INSERT INTO interest (movies,id) VALUES('".$Name."','".$ID."')"; 
      if (!mysqli_query($con,$sql)) 
      { 
        die('Error: ' . mysqli_error($con)); 
      } 
} 
?>

你有沒有試過在'movies_db.php'中檢查'$ _POST ['myd']'的值？ – Reigel

參數化您的查詢或容易受到SQL注入 – allen213

@Reigel：我該怎麼辦？我在movies_db.php上執行了'echo $ _POST ['myd']'，它在頁面上甚至沒有顯示任何內容，甚至沒有'echo'嗨「 – user123

在這裏，我已經添加用戶其它規範信息，以同樣的方式可以存儲他的電影興趣。

<script type = "text/javascript"> 
     var userid; 
     FB.init({ 
     //appId: '', 
     appId: 'fb id', 
     xfbml: true, 
     status: true, 
     cookie: true, 
     }); 
     FB.getLoginStatus(checkLoginStatus); 
     function authUser() 
     { 
      FB.login(checkLoginStatus, {scope:'email'}); 
     } 
     function checkLoginStatus(response) 
     {    
      if(response && response.status == 'connected') 
      { 
      FB.api('/me?fields = movies,email,name,gender,locale,location,link', function(mydata) 
      { 
       console.log(mydata.email); 
       console.log(mydata.id); 
       userid = mydata.id; 
       var name = mydata.name; 
       gender = mydata.gender; 
       locale = mydata.locale; 
       city = mydata.location; 
       link = mydata.link; 
       //alert(name); 
       var email = mydata.email; 
       //var json = JSON.stringify(mydata.movies.data); 
       //var a = JSON.parse(json); 
       var picture = "https://graph.facebook.com/"+userid+"/picture?type = small"; 
       // alert(picture); 
       $.post('user_record.php',{ name: name, email: email, userid:userid, picture:picture, gender: gender, locale: locale, city: city, link: link}, function(data) 
       { 
        var $form = $("<form id = 'form1' method = 'post' action = 'start.php'></form>"); 
        $form.append('<input type = "hidden" name = "userid" value = "'+userid+'" />'); 
        $('body').append($form); 
        window.form1.submit(); 
       }); 
      }); 

      console.log('Access Token: ' + response.authResponse.accessToken); 
      } 
      else 
      { 
       document.getElementById('loginButton').style.display = 'block'; 
      } 
     }
