我正在运行一个代码，该代码应该从数据库中提取调查问卷，以供具有有效会话的用户进行评估。
然而，该页面在运行此php代码时返回一个空白的不完整页面。
我在这里错过了什么吗？
<?php
session_start();
try
{
if(!isset($_SESSION['logged-in']))
{
header("Location: ../index.php");
}
}
catch(Exception $e)
{
}
// php classes
require_once("../classes/database.php");
require_once("../classes/questionnaire.php");
require_once("../classes/competency.php");
require_once("../classes/candidate.php");
require_once("../classes/participant.php");
require_once("../classes/progress.php");
require_once("../classes/user.php");
require_once("../classes/page.php");
// candidate details
if($_SESSION['usertype'] == 'candidate') // if user is doing a self evaluation
{
$candidatename = User::getName($_SESSION['id']);
$candidateusername = $_SESSION['username'];
// questionnaire object
$q = new Questionnaire(Questionnaire::getQuestionnaireName($_SESSION['id']));
}
else if($_SESSION['usertype'] == 'participant') // if user is evaluating their candidate
{
$candidatename = User::getName(Participant::getCandidateID(NULL, $_SESSION['id']));
$candidateusername = Participant::getCandidate($_SESSION['id']);
// questionnaire object
$q = new Questionnaire(Questionnaire::getQuestionnaireName(Participant::getCandidateID(NULL, $_SESSION['id'])));
}
$candidateID = User::getUID($candidateusername);
// objects
$page = new Page('evaluation');
$user = new User($_SESSION['username']);
// page height
$pagename = $page->name;
$page->setHeight(0, true, $q->numCompetencies());
?>
这是HTML必须输出

在标题（....）之后添加退出（0），它可以解决您的问题。
try
{
if(!isset($_SESSION['logged-in']))
{
header("Location: ../index.php");
exit(0);//Add this line
}
}
catch(Exception $e)
{
}

原来我在附带的questionnaire.php文件中遗漏了一个班级。 将错误报告发送到我的PHP文件非常有用。
由于
