Question

我已经使用了可在线获取的脚本。 File upload.php允许用户上传文件，然后将所选文件存储在MySQL数据库中。稍后，download.php脚本显示存储在数据库中的所有文件的链接。当用户单击该链接时，应下载该文件。我已经附上了下面的脚本。但问题是，我没有使用任何upload.php也没有下载.php。我在wordpress中尝试了这个，使用＆＃34; php代码发布（只有短代码放在页面上）＆＃34;一次性。

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

{

$fileName = $_FILES['userfile']['name'];

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

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

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

$fileType = (get_magic_quotes_gpc() == 0 ? mysql_real_escape_string(
$_FILES['userfile']['type']) :
mysql_real_escape_string(stripslashes($_FILES['userfile'])));

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

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

$content = addslashes($content);

fclose($fp);

if(!get_magic_quotes_gpc())

{

$fileName = addslashes($fileName);

}

mysql_connect("localhost","*****","***");

mysql_select_db("****");

$query = "INSERT INTO wp3_cte (FileupName, size, type, content ) ".

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

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

echo "File $fileName uploaded";

}

?>
