$this 和 $row PHP

Question

您好，下面的代码有效：

private function doPreEventStart {
$row = db_fetch_item("SELECT resultid FROM ResultPackage 
where ResultPackage.slotid like {$this->curSlotId}
ORDER BY RAND() LIMIT 1");
$this->curResultId = $row['resultid'];

但是当我添加以下行时：

private function doPreEventStart($this->myusers as $user) {
$row = db_fetch_item("SELECT resultid FROM ResultPackage 
where ResultPackage.slotid like {$this->curSlotId}
and ResultPackage.PackageID like {$user->packageid}
ORDER BY RAND() LIMIT 1");
$this->curResultId = $row['resultid'];

它不再在服务器上运行。我检查了 SQL 数据库，表确实存在。可能有什么问题？谢谢多布罗

我很确定您的函数中的参数分配导致了问题。尝试将其设置为函数定义中的简单参数，但在调用函数时使用 $this->myUsers 等。

private function doPreEventStart($user) {
    $row = db_fetch_item("SELECT resultid FROM ResultPackage 
        where ResultPackage.slotid like '%{$this->curSlotId}%'
        and ResultPackage.PackageID like '%{$user->packageid}%'
        ORDER BY RAND() LIMIT 1");
    $this->curResultId = $row['resultid'];
}
