我在以下代码的标题中收到错误消息，该页面用于向我的论坛添加子类别。
<?php
include '../includes/connect.php';
include '../header.php';
echo '<h2>Create a Sub category</h2>';
if($_SESSION['signed_in'] == false | $_SESSION['user_level'] != 1 )
{
//the user is not an admin
echo 'Sorry, you do not have sufficient rights to access this page.';
}
else
{
//the user has admin rights
if($_SERVER['REQUEST_METHOD'] != 'POST')
{
//the form hasn't been posted yet, display it
echo '<form method="post" action="">
Category name: ';
$sql = "SELECT cat_id, cat_name, cat_description FROM categories";
$result = mysql_query($sql);
echo '<select name="topic_cat">';
while($row = mysql_fetch_assoc($result))
{
echo '<option value="' . $row['cat_id'] . '">' . $row['cat_name'] . '</option>';
}
echo '</select><br />';
echo 'Sub category name: <input type="text" name="sub_cat_name" /><br />
Sub category description:<br /> <textarea name="sub_desc" /></textarea><br /><br />

}
else

//the form has been posted, so save it
$sql = "INSERT INTO subcategories(c_id, sub_cat_name, sub_desc)
VALUES('" . $cat_id . ", " . $sub_cat_name . ", " . $sub_desc . "')";
$result = mysql_query($sql) or die (mysql_error());
echo 'The sub category <b>" . $sub_cat_name . "</b> has been added under the main category <b>" . $cat_name . "</b>';
if(!$result)
{
//something went wrong, display the error
echo 'Error' . mysql_error();
}
else
{
echo 'New Sub category succesfully added.';
}
}
}
; ?>
