当没有用户2的朋友时,隐藏来自用户1的内容

标签: php stream pseudocode privacy if-statement

我有一个我正在使用两个用户流构建的网站。我有合作伙伴的代码,只是在正确的位置使用伪代码的情况下的其他情况..只有它绞尽脑汁。

我需要的是,当我的user1_id访问你时,user2_ids流可以隐藏表单和流,如果我们不是朋友,请告诉我在查看前添加你。显示你已经添加了这位朋友,但朋友还没有接受...或者如果我们是朋友则显示表格和流。

这是所有代码

这是为了确定我的用户及其工作..

<?

$user1_id=$_SESSION['id'];
if($_SESSION['id']==$user1_id){
        define('user_isself','2');
    }else{
        define('user_isself','1');
    }

    $friends = rawfeeds_user_core::check_active_friends($id,$_SESSION['id']);

    define('USER_BEFRIENDED',$friends);

    ?>  

以下是我的两个Feed的代码,来自frist表单的第一个Feed是user1_ids feed和第二个user2_id的feed。

<?php if($user2_id==$_SESSION['id']){ ?>
    <div id="statusholder">
    <div class="divider">
        <h2>Post a status</h2>  
        <form action="insert.php" method="POST" target="ifr1" class="form_statusinput">
        <input type="hidden" name="toid" value="<?php echo $user1_id ?>">
        <input type="text" name="newmsg" id="newmsg" class="homescreen_status_input" placeholder="Say something" autocomplete="off">
        <iframe name="ifr1" id="ifr1" style="display:none;"></iframe>
        <input type="submit" target="ifr1" value="Share" >
    </form>
    </div></div>

    }
}

            ?>

这是我需要插入的代码。

<?php if(USER_BEFRIENDED==0){ ?>
    Add <?php echo $data['fullusersname']; ?> as a friend to see posts and information.
    <?php } 
    if(USER_BEFRIENDED==1){
    ?>
    You've added <?php echo $data['fullusersname']; ?> as a friend, but he hasn't accepted yet. Check back later!
    <?php } }?>

如果我考虑过它..我会在编码user2_id的流之前把它放在代码中。现在我不会在这样的泡菜中。

希望有人可以提供帮助。

谢谢。

2 个答案:

答案 0 :(得分:1)

查看代码,我假设您想要从数据库中获取友谊。我没有看到发布的很多代码的相关性,但我可以提出一些建议:

编写一个函数以返回友情“状态”

我想你会想在其他地方做类似的事情(内容隐藏/原始隐私),所以这有希望是有用的。显然我不能测试这个,但是像:

function checkUserFriendship($user1,$user2)
{
  $sql = "SELECT status FROM friends WHERE user1_id = $user1 AND user2_id = $user2 OR user1_id = $user2 AND user2_id = $user1";
  $query = mysql_query($sql);
  $data  = mysql_fetch_array($query);
  return $data['status'];
}

现在,我非常怀疑它会直接起作用,但它(希望)实现的目标是返回“朋友”表中的“状态”字段。然后你可以在输出时使用它。例如:

$friendshipStatus = checkUserFriendship($user1,$user2);

switch($friendshipStatus){
 case "accepted":
  //Show something
 break;
 case "pending":
  //Show "pending" message
 break;
 case 0:
  //Show nothing (or an error message)
 break;
}

这可能不是你想要的,但这是我将如何处理这种情况。您可能已经使用包含

的行完成了此操作
rawfeeds_user_core::check_active_friends

但你发布了很多代码,我不完全确定它们是如何组合在一起的。

使用Globals

这是一个附注,但我会避免使用已定义的全局变量。它看起来不像是在这里有用。

不必要的代码(?)

在你的用户流中(让我们称之为)你有一大堆代码构造SQL的“IN(n,n,n,n)”部分,只选择某些朋友。我想这在网站的全球/公共/“新闻Feed”部分是必要的,但我看不到你在哪里使用它。 (这可能是我的疏忽/愚蠢!)

答案 1 :(得分:0)

如果不阅读所有代码,我会推荐一个简单的多维数组:

$friends_of_users["user1"] = array("user3", "user9");
$friends_of_users["user2"] = array("user5", "user6");
$friends_of_users["user3"] = array("user1", "user7");

这是伪代码,你应该使用ID代替“userX”,当然。 到目前为止,这不是最性感的解决方案,但它可以解决您的问题。
