我的数据库books的用户名：bookorama，密码：bookorama123
在LINUX 下，查询一切正常
我有个PHP页面用来做查询，但是一直显示空白，请帮我看看代码什么地方有问题
还是我数据库建立有问题；
<html>
<head>
<title>Book-O-Rama Search Results</title>
</head>
<body>
<h1>Book-O-Rama Search Results</h1>
<?php
// create short variable names
$searchtype=$_POST['searchtype'];
$searchterm=$_POST['searchterm'];
$searchterm= trim($searchterm);
if (!$searchtype || !$searchterm)
{
echo 'You have not entered search details. Please go back and try again.';
exit;
}
if (!get_magic_quotes_gpc())
{
$searchtype = addslashes($searchtype);
$searchterm = addslashes($searchterm);
}
@ $db = new mysqli('localhost', 'bookorama', 'bookorama123', 'books');
if (mysqli_connect_errno())
{
echo 'Error: Could not connect to database. Please try again later.';
exit;
}
$query = "select * from books where ".$searchtype." like '%".$searchterm."%'";
$result = $db->query($query);
$num_results = $result->num_rows;
echo '<p>Number of books found: '.$num_results.'</p>';
for ($i=0; $i <$num_results; $i++)
{
$row = $result->fetch_assoc();
echo '<p><strong>'.($i+1).'. Title: ';
echo htmlspecialchars(stripslashes($row['title']));
echo '</strong><br />Author: ';
echo stripslashes($row['author']);
echo '<br />ISBN: ';
echo stripslashes($row['isbn']);
echo '<br />
rice: ';
echo stripslashes($row['price']);
echo '</p>';
}
$result->free();
$db->close();
?>
</body>
</html>
