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>

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。

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！）

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。
