Olá,
Tenho um código em PHP de um sistema de upload. Gostaria de que no final do upload ele gerasse o link do arquivo que foi enviado.
index.php
<html>
<title>Enviar Arquivo</title>
<body>
<form method="post" action="upload.php" enctype="multipart/form-data">
<input type="file" name="Filedata" id="Filedata" />
<input type="submit" value="REALIZAR O UPLOAD" />
</form>
</body>
</html>upload.php
<?php

session_id($_POST["PHPSESSID"]);
} else if (isset($_GET["PHPSESSID"])) {
session_id($_GET["PHPSESSID"]);
}
session_start();// Check post_max_size (http://us3.php.net/manual/en/features.file-upload.php#73762)
$POST_MAX_SIZE = ini_get('post_max_size');
$unit = strtoupper(substr($POST_MAX_SIZE, -1));
$multiplier = ($unit == 'M' ? 1048576 : ($unit == 'K' ? 1024 : ($unit == 'G' ? 1073741824 : 1)));
if ((int)$_SERVER['CONTENT_LENGTH'] > $multiplier*(int)$POST_MAX_SIZE && $POST_MAX_SIZE) {
header("HTTP/1.1 500 Internal Server Error");
echo "POST exceeded maximum allowed size.";
exit(0);

/*
Validating the file contents is OS and web server configuration dependant. Also, it may not be reliable.
See the comments on this page: http://us2.php.net/fileinfo
Also see http://72.14.253.104/search?q=cache:3YGZfcnKDrYJ:www.scanit.be/uploads/php-file-upload.pdf+php+file+command&hl=en&ct=clnk&cd=8&gl=us&client=firefox-a
which describes how a PHP script can be embedded within a GIF image file.
Therefore, no sample code will be provided here. Research the issue, decide how much security is
needed, and implement a solution that meets the needs.

// Process the file
/*
At this point we are ready to process the valid file. This sample code shows how to save the file. Other tasks
could be done such as creating an entry in a database or generating a thumbnail.
Depending on your server OS and needs you may need to set the Security Permissions on the file after it has
been saved.

cannot return data to the server, so it just returns a 500 error. For Flash Player 9 you will
want to change this to return the server data you want to indicate an error and then use SWFUpload'sfunction HandleError($message) {
