Uploadify File Rename - php

I'm using the Uploadify jQuery plugin for PHP to upload a file. One thing I am stuck on is that I need to be able to rename the file being uploaded so that I can post that information to my script that inserts data into the mysql database. Can anyone please advise on how to do this?
Thanks,
Jake

Firstly rename the filename as you want in your uploadify.php
Then you just need to return $targetPath from your uploadify.php file, like this --
echo $targetPath
no need to use echo '1'
And now you have to get the renamed file name. You can get this in onUploadSuccess function.
onUploadSuccess() takes three parameters (file, data, response),
where file gives you the actual name of file you browsed through your computer, and data gives you the renamed file name which you generated through your uploadify.php code as per your requirement.
So you can try the below code --
'onUploadSuccess' : function(file, data, response) {
alert('Renamed file name is - ' + data);
}
I hope this will help out. One of my friend told me this, and I got my work done then :)

you can do like this :-
$targetFolder = FCPATH.'/resources/images/users/temp/'; // Relative to the root
if (!empty($image))
{
$time=strtotime("now");
$image['Filedata']['name']=$time.'.jpg';
$tempFile = $image['Filedata']['tmp_name'];
$targetPath = $targetFolder.$image['Filedata']['name'];
// Validate the file type
$fileTypes = array('jpg','jpeg','gif','png'); // File extensions
$fileParts = pathinfo($image['Filedata']['name']);
if (in_array($fileParts['extension'],$fileTypes))
{
move_uploaded_file($tempFile,$targetPath);
echo '1';
}
else
{
echo 'Invalid file type.';
}
}

If you use uploadify.php just go right before the function move_uploaded_files and change the target name.
Anyways you do it this should work. Post the code you have if you want a more detailed answer.

This will put file in new folder with same file name as source file
$source = $_FILES['Filedata']['tmp_name'];
$filename = $_FILES['Filedata']['name'];
$newPath = $folder.'/'.$filename;
rename($source, $newPath);
/*----------------------*/
to have a new filename
function getExtension($path)
{
$result = substr(strtolower(strrchr($path, '.')), 1);
$result = preg_replace('/^([a-zA-Z]+)[^a-zA-Z].*/', '$1', $result);
if ($result === 'jpeg' || empty($result) === true) {
$result = 'jpg';
}
return $result;
}
$source = $_FILES['Filedata']['tmp_name'];
$filename = $_FILES['Filedata']['name'];
$newfileName=$folder."/"."abc".getExtension($filename);
rename($source, $newfileName);

How to copy an image from one folder to other in php

I have a image named xyz. Besides this file named xyz has unknown extension viz jpg,jpeg, png, gif etc. I want to copy this file from one folder named advertisers/images to other folder publishers/images in my website cpanl. How to do this with php. Thanks in advance.
You can use copy function:
$srcfile = 'source_path/xyz.jpg';
$dstfile = 'destination_path/xyz.jpg';
copy($srcfile, $dstfile);
You should write your code same as below:
<?php
$imagePath = "../Images/somepic.jpg";
$newPath = "../Uploads/";
$ext = '.jpg';
$newName = $newPath."a".$ext;
$copied = copy($imagePath , $newName);
if ((!$copied))
{
echo "Error : Not Copied";
}
else
{
echo "Copied Successful";
}
?>
Use copy() function
copy('advertisers/images/xyz.png','publishers/
images/xyz.png');
Change the file extension, whatever it is.
If you don't know the extension, go with the wildcard. It will give you the array of all the files matching with the wildcard.
$files = glob('advertisers/images/xyz.*');
foreach ($files as $file) {
copy($file,'publishers/images/'.$file);
}

PHP move_uploaded_file doesn't work occasionally?

I now there are lots of same questions here, but I didn't find my answer.
I want to upload an image using move_uploaded_file() function in PHP. Here is my logic?
//check if file uploaded
if (!isset($_POST) || !isset($_FILES)) {
return back();
}
// allowed extensions
$extensions = ['jpg', 'jpeg', 'gif', 'png'];
$fileName = pathinfo($_FILES['profile-image']['name'], PATHINFO_FILENAME);
// save file extension into a variable for later use
$parts = explode('.',$_FILES['profile-image']['name']);
$extension = strtolower(end($parts));
$fileSize = $_FILES['profile-image']['size'];
// check the extension
if (!in_array($extension, $extensions)) {
return back()->withErrors(['File Extension is not valid']);
}
// check if file size is less than 2MB
if ($fileSize >= 2e+6) {
return back()->withErrors(['File Size is too large.']);
}
//check if there is other errors
if ($_FILES['profile-image']['error']) {
return back()->withErrors(['You have anonymus error']);
}
// generate a unique file name
$profile_image = Hash::make($fileName) . '-' . time() . '.' . $extension;
// make a directory if there isn't one
if (!is_dir('public/img')) {
mkdir('public/img');
}
// if current user has an image then delete it
$user = App::get('database')->find('users', compact('id'));
if ($user->profile_image) {
unlink('public/img/' . $user->profile_image);
}
// move image into directory and final check for errors
if( ! move_uploaded_file($_FILES['profile-image']['tmp_name'], 'public/img/' . $profile_image) ) {
return back()->withErrors(['Your file doesn\'t uploaded']);
}
// Insert Uploaded Image into DB.
App::get('database')->update('users', compact('id'), compact('profile_image'));
return redirect('dashboard')->withMessage('Thank for uploading the file.');
I try this code, everything works properly but just sometimes. I don't know why sometimes my uploaded file doesn't move to the directory and sometimes it does. I tried for the same image, sometimes it uploaded and sometimes it failed. This is interesting, because when I upload an image and it fails, can't catch any errors at all.
Did you check max_file_uploads and post_max_size in your php.ini file ?
Maybe the file is bigger than the maximum size allowed.
Regards.
OK, I find the problem. When I hash the image name and save it to DB, sometimes it includes / inside file name, then when I use the file name in image src attribute, it considers the part before the / as another directory.
It might have trouble with,
Your Destination Directory have some writing permission issue.
Try this for manage file permission,
if (!is_writable($url)) {
try {
chmod($url, 0644);
} catch (Exception $e) {
die($e->getMessage() . ' | File : ' . $url . ' | Needs write permission [0644] to process !');
}
}
All the Best !

Uploadify rename more than one file

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.
http://www.uploadify.com/demos/
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.

uploadifive - change filename on upload

I am using uploadifive to upload images - however I want to change the name of the images to "newimage" I am not sure where or how to do this with what is provided - this is the last modification I need to deploy.
You're going to need to do the name change in the PHP script that handles the uploading (I'm assuming your using PHP since that's uplidfy's standard). It can be a bit tricky because you have to separate the incoming file name from it's extension. This should be enough to get you started.
$theFile = $_FILES['file_upl']['name'];
$tempFile = $_FILES['file_upl']['tmp_name'];
$newName = "newname";
$saveDir = $_SERVER['DOCUMENT_ROOT']."/images/";
//Function returns the extension from the '.' on
function get_ext($from_file) {
$ext = strtolower(strrchr($from_file,'.'));
return $ext;
}
//This will rename the file to $newname + the extension
$theFile = $newname.get_ext($theFile);
//Save the file
move_uploaded_file($tempFile,$saveDir.$theFile);
$file = 'uploaded_img.jpg';
$remote_file = 'Saved.txt';
ftp_put($conn_id, $remote_file, $file, FTP_ASCII)
just change the name of the remote file

Why this php file upload validation script not working?

Dear friends, this is a script which simply upload file and insert filename into database, why is this not working ? It's just upload the file and send filename to db even after validation . Please help
<?php
//file validation starts
//split filename into array and substract full stop from the last part
$tmp = explode('.', $_FILES['photo']['name']);
$fileext= $tmp[count($tmp)-1];
//read the extension of the file that was uploaded
$allowedexts = array("png");
if(in_array($fileext, $allowedexts)){
return true;
}else{
$form_error= "Upload file was not supported<br />";
header('Location: apply.php?form_error=' .urlencode($form_error));
}
//file validation ends
//upload dir for pics
$uploaddir = './uploads/';
//upload file in folder
$uploadfile = $uploaddir. basename($_FILES['photo']['name']);
//insert filename in mysql db
$upload_filename = basename($_FILES['photo']['name']);
//upload the file now
move_uploaded_file($_FILES['photo']['tmp_name'], $uploadfile);
// $photo value is goin to db
$photo = $upload_filename;
function send_error($error = 'Unknown error accured')
{
header('Location: apply.php?form_error=' .urlencode($error));
exit; //!!!!!!
}
//file validation starts
//split filename into array and substract full stop from the last part
$fileext = end(explode('.', $_FILES['photo']['name'])); //Ricky Dang | end()
//read the extension of the file that was uploaded
$allowedexts = array("png");
if(!in_array($fileext, $allowedexts))
{
}
//upload dir for pics
$uploaddir = './uploads/';
if(!is_dir($uploaddir))
{
send_error("Upload Directory Error");
}
//upload file in folder
$uploadfile = $uploaddir. basename($_FILES['photo']['name']);
if(!file_exists($uploadfile ))
{
send_error("File already exists!");
}
//insert filename in mysql db
$upload_filename = basename($_FILES['photo']['name']);
//upload the file now
if(move_uploaded_file($_FILES['photo']['tmp_name'], $uploadfile))
{
send_error('Upload Failed, cannot move file!');
}
// $photo value is goin to db
$photo = $upload_filename;
This is a cleared up version to yours, give that a go and see if you get any errors
You can find the extension of file by using this code also.
$tmp = end(explode('.', $_FILES['photo']['name']));
now $tmp got the extension of file.
Why not use PHP's built-in functions to extract the extension from the filename?
$fileext = pathinfo($_FILES['photo']['name'],PATHINFO_EXTENSION);
And if the file extension is valid, you're returning from the function without doing anything further, if it's invalid you're setting the header, but the code logic will continue to your file processing
You blindly assume the file upload succeeded, but there's many reasons for it to fail, which is why PHP provides ['error'] in the $_FILES array:
if ($_FILES['photo']['error'] === UPLOAD_ERR_OK) {
// uploaded properly, handle it here...
} else {
die("File upload error, code #" . $_FILES['photo']['error']);
}
The error codes are defined here.
