Question

这是我的程序可以正常工作并获得用户兴趣，即正确的电影列表。现在我想插入数据库，所以我写了一个ajax调用来做到这一点，

有人可以告诉我它有什么问题，它不会给出错误但也不会插入表格。

我将数据发布到movies_db.php

的index.php

                            }, {scope:'email,user_birthday,status_update,user_about_me'});
                        }
                    }
                }

                // run once with current status and whenever the status changes
                FB.getLoginStatus(updateButton);
                FB.Event.subscribe('auth.statusChange', updateButton);
            };
            (function() {
                var e = document.createElement('script'); e.async = true;
                e.src = document.location.protocol
                    + '//connect.facebook.net/en_US/all.js';

                    button.innerHTML                               = 'Logout';

            function logout(response){

                document.getElementById('debug').innerHTML     =   "";

             function showLoader(status){
                if (status)
                    document.getElementById('loader').style.display = 'block';
                else
                    document.getElementById('loader').style.display = 'none';

         </script>
         <button id="fb-auth">Login</button>
        <div id="loader" style="display:none">
            <img src="ajax-loader.gif" alt="loading" />
        </div>
        <br />
        <div id="user-info"></div>
        <br />
        <div id="debug"></div>
    </body>
</html>

movies_db.php 这部分是正确的，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));
            }
}
?>

在这里，我添加了用户其他个人资料信息，同样可以存储他的电影兴趣。

    <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';
            }
        }
    </script>
