Question

我有以下代码在论坛讨论中显示帖子。

我希望发布反应的人看到两个按钮：

删除按钮
编辑按钮

我似乎找不到将用户会话连接到forumberichten表中的userid的方法。有没有人可以帮我这个？我已经尝试了很多东西，但我一直在所有帖子上都有按钮。

<?php

if (isset($_REQUEST['id'])){
    $id = preg_replace('#[^a-z0-9]#i', '', $_GET['id']);
}

$user = $_SESSION['SESS_USERID'];

if (isset($_REQUEST['user'])){
    $user = preg_replace('#[^a-z0-9]#i', '', $_GET['user']);
}

$sql="SELECT forumberichten.bericht_id,forumberichten.discussieid,forumberichten.userid,forumberichten.omschrijving,forumberichten.datum, forumberichten.active,users.userid,users.username,users.userimage FROM forumberichten,users WHERE forumberichten.userid=users.userid AND forumberichten.active='yes' AND forumberichten.discussieid='".$id."' ORDER BY discussieid DESC";

$result = $conn->query($sql);

if ($result->num_rows >=1) {
    while($row = $result->fetch_assoc()) {
        echo "
            <br><table width='450' border='0'>

            <tr><td bgcolor='#1E1E1E'>&nbsp;</td>

        ";

        if ($row["userimage"] == '') {
            echo "
                <a href='user.php? id=" . $row['userid'] . "'</a>
                <img src='Images/users/nopicture.png' alt='nopicture'  class='user-imagelarge' title='".$row['username']."''>
                </a>
            ";
        } else {
