Question

我一直在努力让每个人的身份都出现在特定事件中。哪个有效。然而，由于某种原因这不起作用。什么时候呢。我在测试的时候意识到，当我把$ userRes-＆gt;关闭在while（$ userRes-＆gt; fetch（））之后，$ user = getUser（$ connection，$ id）工作，但是当它在循环之外时它不起作用。这是我的代码：

$userQuery = "SELECT person_id FROM RosterPeopleEvent WHERE news_id=?;";
$userRes = $connection->prepare($userQuery);
$userRes->bind_param('i', $eventID);
$userRes->execute();
$userRes->bind_result($id);

while ($userRes->fetch()){
    $user = getUser($connection, $id);
    if ($user == $_SESSION["uid"]){
        $p->addContent("You have volunteered for the BBQ <a href=roster.php?rosterid=1&personid=$id&eventid=$eventID&class=remove rel=external>Remove</a>, ");  
    }
    else{
        $p->addContent("$user has volunteered for the BBQ <a href=roster.php?rosterid=1&personid=$id&eventid=$eventID&class=remove rel=external>Remove</a>, "); 
    }                           
}
$userRes->close();

修正版：

$userQuery = "SELECT person_id FROM RosterPeopleEvent WHERE news_id=?;";
$userRes = $connection->prepare($userQuery);
$userRes->bind_param('i', $eventID);
$userRes->execute();
$userRes->bind_result($id);
$userRes->store_result();

while ($userRes->fetch()){
    $user = getUser($connection, $id);
    if ($user == $_SESSION["uid"]){
        $p->addContent("You have volunteered for the BBQ <a href=roster.php?rosterid=1&personid=$id&eventid=$eventID&class=remove rel=external>Remove</a>, ");  
    }
    else{
        $p->addContent("$user has volunteered for the BBQ <a href=roster.php?rosterid=1&personid=$id&eventid=$eventID&class=remove rel=external>Remove</a>, "); 
    }                           
}
$userRes->close();
