Question

我正在开发一个动态网站。我有两个页面，第一个名为＆＃34; testcreatorpd1003.php＆＃34;和另一个＆＃34; databaseconnectpd1003.php＆＃34; 。一切都工作正常，直到我发现每次插入一些数据时，databaseconnectpd1003.php的其他部分正在执行。

以下是代码：

testcreatorpd1003.php

<body oncontextmenu="return false;">
<?php
if (isset($_SESSION['loggedin']) && $_SESSION['loggedin'] == true && $_SESSION['user']=='administrator') 
{

echo'<div class="usercheck"><code><strong>WELCOME , YOU ARE LOGGED IN. QUICK LINKS :</strong>&#160;&#160;<a class="panelbox" href="admin.php">ADMIN PANEL</a></code> || <code><a class="panelbox" href="logout.php">LOGOUT</a></code> </div>';
} 
elseif (isset($_SESSION['loggedin']) && $_SESSION['loggedin'] == true && $_SESSION['user']=='user')
{
echo'<div class="usercheck"><code><strong>WELCOME , YOU ARE LOGGED IN. QUICK LINKS :</strong>&#160;&#160;<a class="panelbox" href="user.php">USER PANEL</a></code> &#160; || &#160;<code><a class="panelbox" href="logout.php">LOGOUT</a> </code></div>';  
 }

else
{
header('Location: faculty-login.php');
}
?>
<div class="addquestion">
<form action="databaseconnectpd1003.php" method="post">
<center>
<b>QUESTION</b> :<br>
<textarea name="question" rows="2" cols="50" placeholder="Please write your question here..." style="margin: auto; width: 70%;"></textarea>
</textarea><br>
<b>OPTIONS</b> :<br>
<strong>OPTION ID : 1</strong>
<input type="text" class="input-generic" name="o1" placeholder="Write first option here"><br>
<strong>OPTION ID : 2</strong>
<input type="text" class="input-generic" name="o2" placeholder="Write second option here"><br>

<input type="text" class="input-generic" name="o3" placeholder="Write third option here"><br>
<strong>OPTION ID : 4</strong>
<input type="text" class="input-generic" name="o4" placeholder="Write fourth option here"><br>
<strong>OPTION ID : 5</strong>
<input type="text" class="input-generic" name="o5" placeholder="Write fifth option here"><br>
<hr>
<b>Correct ID number</b> :

请告诉我我做错了什么。每次我插入一个带有选项的问题及其说的所有内容＆＃34;发生了一些错误。如果错误仍然存在，请联系管理员＆＃34;。一切看起来都很好。请帮忙!!

数据库名称为：onlinetest 表名：pd1003

Answer 1

为安全起见，请尝试按以下方式查询

INSERT INTO pd1003 (field1, field2, field3, field4, field5, field6, field7, field8, field9) VALUES ('$question', '$option1', '$option2', '$option3','$option4', '$option5', '$answer', '$answertext', '$marks')
