What is this code doing?
<?php
if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
$targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];
move_uploaded_file($tempFile,$targetFile);
echo str_replace($_SERVER['DOCUMENT_ROOT'],'',$targetFile);
}
?>
It is basically uploading a file and echoing the target file's name.
There should also be something like an HTML form to send the file to this script.
$_REQUEST['folder']. This value should be send with the request. Do you also have some code like <form> .. some code .. </form>?
It accepts an user uploaded file, and puts it in your webroot in a folder, specified by the user. Then it outputs the path of the uploaded file.
This code is to upload a file in the destination directory. Is there anything else do you want to understand.
This will upload the file in the path you have in variable $_REQUEST['folder']
Storing files uploaded (possibly via HTML form) onto server.
It's accepting a file posted by a HTML form and uploading it to a certain directory within a server. After that it's displaying the location of the file on screen (in the browser).
