这是我的代码,但我不知道错误在哪里
上面说我出现了错误,即注意:
Undefined index: ic in C:'xampp'htdocs'fyp'profile.php on line 57.
<?php
include_once("config.php");
$ic = $_SESSION['ic'];//-----------------------------------this is line 57
$sql = "SELECT * FROM studentprofile WHERE ic = '$ic'";
$result = mysql_query($sql,$conn);
while($row = mysql_fetch_array($result))
{
$id = $row['id'];
$ic = $row['ic'];
$name = $row['name'];
$course = $row['course'];
$faculty = $row['faculty'];
$address = $row['address'];
$hpno = $row['hpno'];
$gender = $row['gender'];
$email = $row['email'];
?>
<table width="70%" height="80%" border="1" align="center">
<tr>
<th>ID</th>
<td><?php echo $id;?></td>
</tr>
<tr>
<th>IC No</th>
<td><?php echo $ic;?></td>
</tr>
<tr>
<th>Name</th>
<td><?php echo $name;?></td>
</tr>
<tr>
<th>Course</th>
<td><?php echo $course;?></td>
</tr>
<tr>
<th>Faculty</th>
<td><?php echo $faculty;?></td>
</tr>
<tr>
<th>Address</th>
<td><?php echo $address;?></td>
</tr>
<tr>
<th>Handphone No</th>
<td><?php echo $hpno;?></td>
</tr>
<tr>
<th>Gender</th>
<td><?php echo $gender;?></td>
</tr>
<tr>
<th>Email</th>
<td><?php echo $email;?></td>
</tr>
</table>
<?php
}
?>
我想试着把它放进去。但我不知道怎么做。我已经尝试删除include_one("config.php")以包含("configphp"),但什么也没发生。
我已经在php中开始了会话。有人能帮我找出我的编码出了什么问题吗?
此编码用于查看已登录系统的人员的配置文件。例如,我登录到系统,当我查看配置文件时,只会显示我的配置文件。因此,我尝试使用我之前发布的代码。
但这是错误的。我已经将数据库中的ic属性设置为主键。
您使用了吗
session_start();
之前您在该PHP文件中使用了任何$_session?
会话变量在第一次请求时是空数组,所以您可以初始化它:
session_start();
if(!isset($_SESSION['ic']))
{
$_SESSION['ic'] = 'my default value';
}
$ic = $_SESSION['ic'];
在尝试访问会话之前,您应该确保会话已经存在。您开始使用会话时没有这样做。这是我的建议:
<?php
// YOU SHOULD MAKE SURE THE SESSION EXIST FIRST BEFORE USING IT...
// THIS SHOULD BE THE FIRST LINE OF CODE IN YOUR SCRIPT IF YOU ARE USING SESSION:
if (session_status() == PHP_SESSION_NONE || session_id() == '') {
session_start();
}
include_once("config.php");
$ic = isset($_SESSION['ic'])? $_SESSION['ic'] : null;
$sql = "SELECT * FROM studentprofile WHERE ic = '$ic'";
$result = mysql_query($sql,$conn);
while($row = mysql_fetch_array($result))
{
$id = $row['id'];
$ic = $row['ic'];
$name = $row['name'];
$course = $row['course'];
$faculty = $row['faculty'];
$address = $row['address'];
$hpno = $row['hpno'];
$gender = $row['gender'];
$email = $row['email'];
?>
<table width="70%" height="80%" border="1" align="center">
<tr>
<th>ID</th>
<td><?php echo $id;?></td>
</tr>
<tr>
<th>IC No</th>
<td><?php echo $ic;?></td>
</tr>
<tr>
<th>Name</th>
<td><?php echo $name;?></td>
</tr>
<tr>
<th>Course</th>
<td><?php echo $course;?></td>
</tr>
<tr>
<th>Faculty</th>
<td><?php echo $faculty;?></td>
</tr>
<tr>
<th>Address</th>
<td><?php echo $address;?></td>
</tr>
<tr>
<th>Handphone No</th>
<td><?php echo $hpno;?></td>
</tr>
<tr>
<th>Gender</th>
<td><?php echo $gender;?></td>
</tr>
<tr>
<th>Email</th>
<td><?php echo $email;?></td>
</tr>
</table>
<?php
}
?>
如果你已经创建了一个会话,那么使用:
session_start();
或者,如果你想创建一个新的,请使用:
$_SESSION['ic'] = $row['ic'];
