现在,我确实在为此而努力,而且似乎不能让它发挥作用。 成员.php(我展示了所有登记用户) 我有一个名单,每个用户旁边有一个链接“ADD与FRIENDS”。

为了测试目的,我设法显示每个成员都很好(从而获得身份证),但当我点击其与朋友的联系时。 它在哪里似乎有过错。 我不知道如何让这位朋友在朋友们点击我。 php file. 请看一看!

members.php

<?php
        include  connect.php ;
        include  header.php ;

        if(isset($_SESSION[ signed_in ]) == false || isset($_SESSION[ user_level ]) != 1 )
            {
                //the user is not an admin
                echo  <br/> ;
                echo  Sorry! You have to be <a href="/signin.php"><b>logged in</b></a> to view all the <a href="signup_2.php" title="Become a registered user!"><b>registered</b></a> members. ;
                echo  <br/><br/> ;
            }
            else
            {
                echo  <h2>Registered users:</h2> ;

                $sql    = "SELECT * FROM users ORDER BY user_name ASC";
                $result = mysql_query($sql);

                $num=mysql_numrows($result);

                $i=0;
                while ($i < $num)
                {
                    //$name = mysql_result($result,$i,"user_name");
                    //$id = mysql_result($result,$i,"user_id");
                    //$picture = mysql_result($result,$i,"pic_location");

                    //?friend_id=" . $id . 
                    while($user = mysql_fetch_array($result)){
                        echo $user[ user_name ]. <br/><br/><a href="friends.php?user= .$user[ user_id ]. ">ADD TO FRIENDS</a><br/> ;
                        echo $user[ user_id ];
                        echo  <br/><br/> ;
                    }

                    $i++;
                }

                ///////////////////////////////
                /// adding users as friends ///
                ///////////////////////////////

                //while($user = mysql_fetch_array($result))
                //echo $user[ user_name ].  
                    //<a href="addfriend.php?user= .$user[ id ]. ">ADD TO FRIENDS</a><br/> ;


                //NOW I WANT TO MAKE A SPECIFIC "ADD AS FRIEND" LINK NEXT TO EACH USER


            }
            include  footer.php ;
?>

正如我说过的那样,我不敢肯定如何做到这一点,请看一看! 感谢!
