I am trying to use Uploadify on my site and have it setup with the following uploadify.php:
<?php
// Define a destination
//$targetFolder = '/uploads'; // Relative to the root
if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'];
$targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];
// Validate the file type
$fileTypes = array('jpg','jpeg','gif','png'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);
if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$targetFile);
echo '1';
} else {
echo 'Invalid file type.';
}
}
?>
It wasn't uploading so I commented out $targetFolder and changed $targetPath so that it is just the document root. This results in $targetFile being /home/user/public_html/example.com/file.txt when I try to upload file.txt with Uploadify. The folder is set to 755. I'm at a loss as to what the problem could be. I am otherwise using a vanilla install of Uploadify and everything seems to work fine except that the file never actually goes where it should.
It was an issue with the folder permissions not staying set to 755. I logged out of and back into cPanel and everything's working now.

I am using Uploadify to upload a file. The filename is randomized by the PHP when uploaded. I need to echo the file name back to the JS. I don't know enough PHP to do this.
Here is my PHP Script:
<?php
$targetFolder = '/uploads';
$verifyToken = md5('unique_salt' . $_POST['timestamp']);
if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
$fileParts = pathinfo($_FILES['Filedata']['name']);
$targetFile = sprintf('%s/%s.%s', $targetPath, uniqid(), $fileParts['extension']);
// Validate the file type
$fileTypes = array('jpg','jpeg','gif','png','doc','docx','pdf','xlsx','pptx','tiff','tif','odt','flv','mpg','mp4','avi','mp3','wav','html','htm','psd','bmp','ai','pns','eps'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);
if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$targetFile);
echo '1';
} else {
echo 'Invalid file type.';
}
}
?>
If I understand the script correctly where the echo '1' at the bottom of the script is where the file name should be. How do I insert the changed or randomized file name there?
Your $targetFile variable contains the full path to your uploaded file (once moved). If you just want the filename part, use basename(), eg
echo basename($targetFile);
See http://php.net/basename
I am using Uploadify and when a person uploads the file I want the file name to be a random generated file name. Numbers would be fine.
Here is the current PHP I am using:
<?php
$targetFolder = '/uploads';
$verifyToken = md5('unique_salt' . $_POST['timestamp']);
if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
$targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];
// Validate the file type
$fileTypes = array('jpg','jpeg','gif','png','doc','docx','pdf','xlsx','pptx','tiff','tif','odt','flv','mpg','mp4','avi','mp3','wav','html','htm','psd','bmp','ai','pns','eps'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);
if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$targetFile);
echo '1';
} else {
echo 'Invalid file type.';
}
}
?>
I tried replacing this:
$targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];
with this (per this answer):
$fileParts = pathinfo($_FILES['Filedata']['name']);
$targetFile = rtrim($targetPath,'/') . '/' .rand_string(20).'.'.$fileParts['extension'];
but that did not work, in fact, it stopped the file from uploading at all.
How do I modify the script to create random file names? Note: I know almost no PHP, please make any answer clear for a beginner.
I'd use uniqid() as I have no idea what rand_string is or where it comes from, eg
$fileParts = pathinfo($_FILES['Filedata']['name']);
$targetFile = sprintf('%s/%s.%s', $targetPath, uniqid(), $fileParts['extension']);
Another thing I never do is rely on DOCUMENT_ROOT. Instead, use a path relative from the current script. For example, say your script is in the document root
$targetPath = __DIR__ . '/uploads';
I'm using uploadify on a project, and I've got the php script renaming a single file, but I'm unsure how to repeat the process if more than one file is uploaded at a time?
My php script is below...
$targetFolder = '/img/uploads'; // Relative to the root
$verifyToken = md5('unique_salt' . $_POST['timestamp']);
if (!empty($_FILES) && $_POST['token'] == $verifyToken) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
$fileParts = pathinfo($_FILES['Filedata']['name']);
$unique_hash = hash_hmac("md5", file_get_contents($_FILES['Filedata']['name']), SALT);
$targetFile = rtrim($targetPath,'/') . '/' . $unique_hash .'-'.$_POST['userId'].'.'. $fileParts['extension'];
#$targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];
// Validate the file type
$fileTypes = array('jpg','jpeg','gif','png'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);
if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$targetFile);
echo '1';
} else {
echo 'Invalid file type.';
}
}
When you use ajax, you can send a request for every file just one by one then you wont have to use a foreach or you send the form at once and use the code below here.
When you send all file together you will be using in your form something like this: name=userfile[] so you can foreach the files like this:
foreach ($_FILES as $file)
{
$uploadfile = $uploaddir . basename($file['name']);
if (!move_uploaded_file($file["tmp_name"], $uploadfile))
{
echo set_e('error','Image ['.$i.'] not uploaded','');
}
}
Have you tried to do more than one? Uploadify uses jQuery ajax to process the files? It might look simultaneous but it processes one file at a time via ajax. It will call your upload.php as many times as there are files in the queue. So if your function works for one file, it will for the rest. You just need to make sure it's writing a unique filename in the directory every time the function is called whic it looks like it does. Uploadify handles looping through each file name then calls your upload script.

Look at the network console with Chrome or Firebug and upload a bunch of pictures with on the demo. you'll see the upload.php script is called for each file.
FYI,
I used to use uploadify but I changed to PLUPLOAD http://www.plupload.com/. Supports multiple uploads too but better documented and easier to use with great api's.
I am using Uploadify for my script.
The main page:
<?php
session_start();
var_dump($_SESSION);
$uploaded_files = $_SESSION['uploaded_files'];
?>
//Uploadify, HTML forms and more (not related, No PHP in this section)
uploadify.php:
<?php
session_start();
require_once('includes/functions.php');
// Define a destination
$targetFolder = 'uploads/temp'; // Relative to the root
if (!empty($_FILES)) {
$fileParts = pathinfo($_FILES['Filedata']['name']);
$file_hash = GenRndStr(20) . '.' . $fileParts['extension'];
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $targetFolder;
$targetFile = rtrim($targetPath,'/') . '/' . $file_hash;
// Validate the file type
$fileTypes = array(); // File extensions
move_uploaded_file($tempFile, $targetFile);
$_SESSION['uploaded_files'][] = $file_hash;
echo '1';
}
?>
I'm sure it gets to the $_SESSION['uploaded_files'][] = $file_hash; part, since the actual file is uploaded to the directory. My problem is that the var_dump of $_SESSION['uploaded_files'] returns null.
The files are in the same directory level.
Thanks in advance.
I found the solution. The problem is that Uploadify's flash version is treated as a different client for the server, therefore the server creates a new session id for it.
I followed this topic: http://www.uploadify.com/forum/#/discussion/43
Hope it'll help others.
I'm having an issue where the path of my file upload isn't being assigned to the correct folder. It actually amends the file path to the file name of the file being uploaded. Weird right? Here's the code I'm working on...
<?php
$allowed_filetypes = array('.mp4','.gif','.bmp','.png','.html','.psd','.zip','.xml','.css','.js',);
$max_filesize = 5904288;
$upload_path = 'video';
$filename = $_FILES['userfile']['name'];
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);
if(!in_array($ext,$allowed_filetypes))
die('Sorry, cannot take files over blankKB.');
if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
die('Sorry, cannot take files over blankKB.');
if(!is_writable($upload_path))
die('We are very sorry, a problem is occurring with the CHMOD of this directory');
if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename))
echo ' Your file was uploaded successfully, view it here';
else
echo 'Sorry, but there was an error during the file upload. Please try again.';
?>
Here's what the file looks like after being uploaded,
videoHello.png
plus it doesn't upload the file to the directory I want it in, located at /video
When you write $upload_path . $filename you are only concatenating the two strings, which does indeed result in videoHello.png;
You should either concatenate your system's directory separator (On Unix based systems it's /)
$upload_path . '/' . $filename
or build the separator into your string $upload_path
$upload_path = 'video/';
Though my final advice would be to use Absolute Paths like this:
$upload_path = dirname(__FILE__) . '/video/';
