Having a Link Only Appear If a Logged-In User Appears on a Dynamic List

[ArizonaJohn]

Hello,

 

For the function below, I would like the link

<div class="footervote"><a href="http://www...com/.../footervote.php">Vote</a></div>

to only appear if the logged in user currently appears on editorlist.php. (I. e. if the

loginid

in the function corresponds to any of the usernames that currently appear in editorlist.php.)

 

Appearing on editorlist.php is something that is dynamic.

 

How can I do this?

 

Thanks in advance,

 

John

 

function show_userbox()
{
    // retrieve the session information
    $u = $_SESSION['username'];
    $uid = $_SESSION['loginid'];
    // display the user box
    echo '<div id="userbox">

                <div class="username">'.$u.'</div>              
                <div class="submit"><a href="http://www...com/.../submit.php">Submit an item.</a></div>
                <div class="changepassword"><a href="http://www...com/.../changepassword.php">Change Password</a></div>
                <div class="logout"><a href="http://www...com/.../logout.php">Logout</a></div>
                <div class="footervote"><a href="http://www...com/.../footervote.php">Vote</a></div>

         </div>';
}

 

On editorlist.php:

 

$sqlStr = "SELECT 
    l.loginid, 
    l.username, 
    l.created,
    DATEDIFF(NOW(), l.created) AS days,
    COALESCE(s.total, 0) AS countSubmissions, 
    COALESCE(c.total, 0) AS countComments,
    COALESCE(s.total, 0) * 10 + COALESCE(c.total, 0) AS totalScore,
    DATEDIFF(NOW(), l.created) + COALESCE(s.total, 0) * 10 + COALESCE(c.total, 0) AS totalScore2
FROM login l    
LEFT JOIN (
    SELECT loginid, COUNT(1) AS total 
    FROM submission 
    GROUP BY loginid
) s ON l.loginid = s.loginid
LEFT JOIN (
    SELECT loginid, COUNT(1) AS total 
    FROM comment 
    GROUP BY loginid
) c ON l.loginid = c.loginid
GROUP BY l.loginid
ORDER BY totalScore2 DESC 
LIMIT 10";

  $result = mysql_query($sqlStr);

$arr = array(); 
echo "<table class=\"samplesrec1edit\">";
while ($row = mysql_fetch_array($result)) { 
    echo '<tr>';
    echo '<td class="sitename1edit1"><a href="http://www...com/.../members/index.php?profile='.$row["username"].'">'.stripslashes($row["username"]).'</a></td>';
    echo '<td class="sitename1edit2">'.($row["countSubmissions"]).'</td>';
    echo '<td class="sitename1edit2">'.($row["countComments"]).'</td>';
    echo '<td class="sitename1edit2">'.($row["days"]).'</td>';
    echo '<td class="sitename1edit2">'.($row["totalScore2"]).'</td>';
    echo '</tr>';
    }
echo "</table>";

check the "loginid" against the session loginid

if it exists hen only call the function.
