用php上传pdf文件到mysql数据库

Question

我没有错误，连接正常，但我的数据库没有收到任何数据。我一直在关注一个教程而不是我自己的代码，但是我无法看到我在哪里犯了错误。

我创建了一个名为files的表，它与下面代码中使用的参数相对应。

代码位于名为uploader.php的文件中：

<?php if(isset($_POST['uploader']) && $_FILES['userfile']['size'] > 0)

 {
 echo "working";
 $fileName = $_FILES['userfile']['name'];

$tmpName  = $_FILES['userfile']['tmp_name'];

$fileSize = $_FILES['userfile']['size'];

$fileType = $_FILES['userfile']['type'];

$fp      = fopen($tmpName, 'r');

$content = fread($fp, filesize($tmpName));

$content = addslashes($content);

fclose($fp);

if(!get_magic_quotes_gpc())

{

$fileName = addslashes($fileName);

}

mysql_connect("localhost","root","root");

mysql_select_db("globe_bank");

$query = "INSERT INTO files (name, size, type, content ) ".

"VALUES ('$fileName', '$fileSize', '$fileType', '$content')";

mysql_query($query) or die('Error, query failed');

echo "
File $fileName uploaded
";

}

?>
