更新到 PHP 版本 7.3.11 后出现表单上传错误

Form upload errors after updating to PHP version 7.3.11

在我们的主机将 PHP 版本更新到 7.3.11 之前,我有一个正常工作的表单。现在,当您尝试提交表单时,它会给出此错误消息:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function sl_upload(), 2 passed in /nfs/c07/h03/mnt/113634/domains/myurl.com/html/appLms/modules/question/class.upload.php on line 331 and exactly 3 expected in /nfs/c07/h03/mnt/113634/domains/myurl.com/html/lib/lib.upload.php:74 Stack trace: #0 /nfs/c07/h03/mnt/113634/domains/myurl.com/html/appLms/modules/question/class.upload.php(331): sl_upload('/var/tmp/phpU0P...', '/appLms/test/2_...') #1 /nfs/c07/h03/mnt/113634/domains/myurl.com/html/appLms/lib/lib.test.php(1106): Upload_Question->storeAnswer(Object(Track_Test), Array, '1') #2 /nfs/c07/h03/mnt/113634/domains/myurl.com/html/appLms/modules/test/do.test.php(1208): PlayTestManagement->storePage('1', '1') #3 /nfs/c07/h03/mnt/113634/domains/myurl.com/html/appLms/modules/test/do.test.php(592): showResult(Object(Learning_Test), 29) #4 /nfs/c07/h03/mnt/113634/domains/myurl.com/html/appLms/class.module/learning.test.php(309): in /nfs/c07/h03/mnt/113634/domains/myurl.com/html/lib/lib.upload.php on line 74

我没有更改任何代码。唯一改变的是 PHP 版本。因此,我什至不确定如何开始解决这个问题。

    } else {
        $event = new \appCore\Events\Core\FileSystem\UploadEvent($srcFile, $dstFile);
        \appCore\Events\DispatcherManager::dispatch(\appCore\Events\Core\FileSystem\UploadEvent::EVENT_NAME, $event);
        unlink($srcFile);
        return $event->getResult();
    }
}

基于此,我不确定要更改什么,我不想破坏之前的工作。

网站的其他所有功能都正常运行,包括 PHP 功能,例如登录。在此先感谢您的指点。

尝试替换:

sl_upload($_FILES['quest']['tmp_name'][$this->id], $path.$savefile)

与:

sl_upload($_FILES['quest']['tmp_name'][$this->id], $path.$savefile, null);

解释:sl_upload 函数需要 3 个参数,而您只传递了 2 个。

Before PHP 7.1, this only triggered a warning, but since then it's generating a Fatal Error instead.

因为它之前对你工作得很好(虽然,它一定触发了一个警告,除非你的 error_reporting 非常松懈,否则它可能被记录在某个地方),传递 null 作为第三个参数应该产生与以前相同的结果。

然而,弄清楚该函数参数应该用于什么是更好的主意,因为它被标记为必需(无默认值)。
