You haven't set your endpoint correctly, it appears. Your endpoint must be a relative or absolute URL pointing at the location on your server setup to handle Fine Uploader's requests. It also looks like you may not be running your app in a webserver. It seems like you are simply opening up a web browser and pointing at an html file on your filesystem. That is never going to work.
Please see the demos on fineuploader.com as well as the request option documentation in the readme.

[PHP][SLIM] move_uploaded_file never ends with larger files in Hosting24

I have a question.
I'm trying to upload files to a server, this server is hosted by 'Hosting24', i don't know if that matters, anyway, if I try to move files larger than 70mb It never ends to load and never send a response, my server config is okay, it has these values: {"post_max_size":"512M","memory_limit":"1024M"}
I has tryed with $_FILES and ftp transfer and it doesnt works, it never ends of load.
I'm using Slim framework and this is the function:
public function testCode($request, $response, $args)
{
$data = $request->getParsedBody();
$uploadedFiles = $request->getUploadedFiles();
//here take files
$uploadedFile = $uploadedFiles['file_user'];
$nameC = $data['nombre_curso'];
//here set path
$path = "../../scorm/temp/" . $nameC . '/';
//Creating folders
if (!#mkdir($path, 0777, true)) {
$error = error_get_last();
echo $error['message'];
}
$file_name = $uploadedFile->getClientFilename();
$array = explode(".", $file_name);
$ext = $array[1];
//if is a zip file
if ($ext == 'zip') {
$location = $path . "/" . $file_name;
//here move the uploaded file to my selected directory
if (move_uploaded_file($uploadedFile->file, $location)) {
$obj = (object) array("response" => 'works', 'post_max_size' => ini_get('post_max_size'), 'memory_limit' => ini_get('memory_limit'));
$response->withStatus(200);
$response->getBody()->write(json_encode($obj));
return $response;
} else {
$error = error_get_last();
echo $error['message'] . " it couldn't be moved";
}
} else {
echo "no zip";
}
}

valums ajax-upload broken script after xhr.send(file) - sometimes works, and sometimes does not

I searched for solution to this the better part of the day and I'm still in the dark. For a client of mine I created a simple web gallery for uploading images and I'm using valums file uploader. Till now I didn't have any problems with it on any other site I created, except miss-configuration which I solved some time ago.
So, what is the problem?
When I upload a image with filesize below 260KB it works fine. But, when I'm uploading a bigger image, it doesn't throw me back any error. I just get an empty thumbnail, because image wasn't uploaded.
When I open Chrome Console, this is what I see:
POST http://designflowstudio.com/gallery2/include/upload.php?url=uploads%2Fe558c4dfc2a0f0d60f5ebff474c97ffc&fid=7&qqfile=316267269718409738080100.jpg 403 (Forbidden) fileuploader.js:1463
POST http://designflowstudio.com/gallery2/include/upload.php?url=uploads%2Fe558c4dfc2a0f0d60f5ebff474c97ffc&fid=7&qqfile=3.jpg 403 (Forbidden) fileuploader.js:1463
On some occasions I got 413 error "Request entity too large".
Let me say that this problem really annoys me because the script works well on my local web server (apache) and on my web server. Here I can upload as may and as big images as I can find, but on the client's web server...
If anyone have time and will to help me, here is the JavaScript that I use to call the valums uploader:
function createUploader(){
var uploader = new qq.FileUploaderBasic({
debug: true,
multiple: true,
allowedExtensions: [<?php $tmp=".";foreach($allowedExt as $ext){$tmp.="'$ext', ";}echo substr($tmp,1,strlen($tmp)-3);?>],
button: document.getElementById('uploadDiv'),
action: '<?php echo$home;?>include/upload.php',
sizeLimit: <?php echo$sizeLimit;?>,
forceMultipart: true,
params: {'url':'uploads/<?php echo$g['path'];?>','fid':'<?php echo$g['id'];?>'},
onSubmit: function(id, fName){$('#upload-list').append('<div id="upload-list-'+id+'" class="gallery" rel="'+fName+'"><div class="progress'+id+'"></div>');$('.progress'+id).progressbar({value:0})},
onProgress: function(id, fName, loaded, total){
var p = 0;
p = parseFloat(loaded/total*100);
if(isNaN(p)) p = '';
$('.progress'+id).progressbar("option","value",p);
},
onComplete: function(id,fName,json){
if(json.error){
$('#upload-list-'+id).html(fName+'<br />'+json.error);
}else{
$('#upload-list-'+id)
.attr("rel",json.fname)
.html('<img class="cmd" id="deleteImg" rel="'+json.id+'" src="<?php echo$home;?>images/delete.png" title="Delete picture" /><img class="img" src="<?php echo$home;?>uploads/<?php echo$g['path'];?>/th_'+json.fname+'" /><input class="ut" type="text" name="name" value="'+json.name+'" /><input class="ud" type="text" name="desc" /><div class="cl"></div>')
.attr("id",json.id);
}
},
onError: function(id,fName,error){
console.log(id+' '+fName+' '+error);
}
});
}
window.onload = createUploader;
And here is my PHP for server processing the file:

Let me say again, all the calls to MySQL, files with require() are valid. The scripts work on two other servers, but on this one, not.
Thank you for your time and will to help.
You have some configuration issues on your server if it is choking due to the content-type header. Instead of commenting out this line, to work around this messed up server, you should perhaps try to set the forceMultipart option to true, assuming your server can handle multipart-encoded requests correctly. This all assumes you are using the 2.1-SNAPSHOT version of the uploader, as the option I mentioned first appeared in this version.

Adding image file check security to Valums Ajax Uploader

I've been doing research on image file upload security for a while but can't seem to crack it. I want to add some security to the fantastic Valums Ajax Uploader by checking whether or not a file is actually an image before saving to a server. The only extensions allowed are .jpg, .png and .gif, which of course the extensions are checked but I'm looking to validate it's an image file via GD processing. I know very little about this subject so I'm taking cues from this and this post. As it stands now, I can easily save a random file with an image extension and it will be saved the server, which I want to prevent. Here is the script I've come up with thus far, which I've added to the handleUpload function in the php.php file. Unfortunately the result is that it returns an error no matter what file I upload, valid image or not. Please excuse my utter newbishness.
$newIm = #imagecreatefromjpeg($uploadDirectory . $filename . '.' . $ext);
$newIm2 = #imagecreatefrompng($uploadDirectory . $filename . '.' . $ext);
$newIm3 = #imagecreatefromgif($uploadDirectory . $filename . '.' . $ext);
if (!$newIm && !$newIm2 && !$newIm3) {
return array('error' => 'File is not an image. Please try again');
}else{
imagedestroy($newIm);
imagedestroy($newim2);
imagedestroy($newIm3);
}

If someone can point me in the right direction about what I'm doing wrong, it would be most appreciated.
Edit:
Thanks Mark B for the help and clarification. So the new code (which I pasted in the same location as the old, the handleUpload function) is still throwing an error no matter what I upload, so I wonder if it needs to be in a different place -- I'm just not sure where to put it.
$newIm = getimagesize($uploadDirectory . $filename . '.' . $ext);
if ($newIm === FALSE) {
return array('error' => 'File is not an image. Please try again');
}
Second Edit:
I believe the answer is here, still trying to implement it.
Just use getimagesize():
$newIm = getimagesize$uploadDirectory . $filename . '.' . $ext');
if ($newIm === FALSE) {
die("Hey! what are you trying to pull?");
}
The problem with your code is the 3 imagecreate calls and subsequent if() statement. It should have been written as an OR clause. "if any of the image load attempts fail, then complain". Yours is written as "if all image attempts fail", which is not possible if a gif/jpg/png actually was uploaded.
The answer detailed here works like a charm, I wish I had seen it before posting. I hope I implemented it correctly...as I have it, it works!
class qqUploadedFileXhr {
/**
* Save the file to the specified path
* #return boolean TRUE on success
*/
function save($path) {
// Store the file in tmp dir, to validate it before storing it in destination dir
$input = fopen('php://input', 'r');
$tmpPath = tempnam(sys_get_temp_dir(), 'upload'); // upl is 3-letter prefix for upload
$tmpStream = fopen($tmpPath, 'w'); // For writing it to tmp dir
$realSize = stream_copy_to_stream($input, $tmpStream);
fclose($input);
fclose($tmpStream);
if ($realSize != $this->getSize()){
return false;
}
$newIm = getimagesize($tmpPath);
if ($newIm === FALSE) {
return false;
}else{
// Store the file in destination dir, after validation
$pathToFile = $path . $filename;
$destination = fopen($pathToFile, 'w');
$tmpStream = fopen($tmpPath, 'r'); // For reading it from tmp dir
stream_copy_to_stream($tmpStream, $destination);
fclose($destination);
fclose($tmpStream);
return true;
}
}

PHP File Type Validation

I wrote the following php function to upload files but I'm having a hard time with the array of allowed file types. If I assign just one file type i.e. image/png, it works fine. If I assign more than one, its not working. I use the in_array() function to determine the allowed file types but I can't figure out how to use it properly.
Thank you!
function mcSingleFileUpload($mcUpFileName, $mcAllowedFileTypes, $mcFileSizeMax){
if(!empty($mcUpFileName)){
$mcIsValidUpload = true;
// upload directory
$mcUploadDir = UPLOAD_DIRECTORY;
// current file properties
$mcFileName = $_FILES[$mcUpFileName]['name'];
$mcFileType = $_FILES[$mcUpFileName]['type'];
$mcFileSize = $_FILES[$mcUpFileName]['size'];
$mcTempFileName = $_FILES[$mcUpFileName]['tmp_name'];
$mcFileError = $_FILES[$mcUpFileName]['error'];
// file size limit
$mcFileSizeLimit = $mcFileSizeMax;
// convert bytes to kilobytes
$mcBytesInKb = 1024;
$mcFileSizeKb = round($mcFileSize / $mcBytesInKb, 2);
// create array for allowed file types
$mcAllowedFTypes = array($mcAllowedFileTypes);
// create unique file name
$mcUniqueFileName = date('m-d-Y').'-'.time().'-'.$mcFileName;
// if file error
if($mcFileError > 0)
{
$mcIsValidUpload = false;
mcResponseMessage(true, 'File error!');
}
// if no file error
if($mcFileError == 0)
{
// check file type
if( !in_array($mcFileType, $mcAllowedFTypes) ){
$mcIsValidUpload = false;
mcResponseMessage(true, 'Invalid file type!');
}
// check file size
if( $mcFileSize > $mcFileSizeLimit ){
$mcIsValidUpload = false;
mcResponseMessage(true, 'File exceeds maximum limit of '.$mcFileSizeKb.'kB');
}
// move uploaded file to assigned directory
if($mcIsValidUpload == true){
if(move_uploaded_file($mcTempFileName, $mcUploadDir.$mcUniqueFileName)){
mcResponseMessage(false, 'File uploaded successfully!');
}
else{
mcResponseMessage(true, 'File could not be uploaded!');
}
}
}
}
}
//mcRequiredFile('mcFileUpSingle','please select a file to upload!');
mcSingleFileUpload('mcFileUpSingle', 'image/png,image/jpg', 2097152);
Change this line:
$mcAllowedFTypes = array($mcAllowedFileTypes);
To this:
$mcAllowedFTypes = explode(',',$mcAllowedFileTypes);
Don't rely on the clent file type from $_FILES which is unsafe, get it from the file content.
Then define your allowed file types, check if the upload file type in your white list.
if(in_array(mime_type($file_path),$allowed_mime_types)){
// save the file
}
$allowed_mime_types = array(
'image/jpeg',
'image/jpg',
'image/png',
'image/gif',
'video/mp4'
);
/*
For PHP>=5.3.0, you can use php's `finfo_file`([finfo_file](https://www.php.net/manual/en/function.finfo-file.php)) function to get the file infomation about the file.

Joomla custom user extension

I'm writing a Joomla 1.5 extension for an advanced frontend user interface.
Now I have to add a function so the users can upload a picture in the frontend and it will be added to their account.
Is there a standard Joomla picture upload available or something?
Thanks
I have this is my code: (and some more I can not paste everything in here)
function deleteLogo($logo)
{
// define path to file to delete
$filePath = 'images/stories/members/' . $logo;
$imagePath = 'images/stories/members/image/' . $image;
// check if files exists
$fileExists = JFile::exists($filePath);
$imageExists = JFile::exists($imagePath);
if($fileExists)
{
// attempt to delete file
$fileDeleted = JFile::delete($filePath);
}
if($imageExists)
{
// attempt to delete file
$fileDeleted = JFile::delete($imagePath);
}
}
function saveLogo($files, $data)
{
$uploadFile = JRequest::getVar('logo', null, 'FILES', 'ARRAY');
$uploadImage = JRequest::getVar('image', null, 'FILES', 'ARRAY');
$save = true;
$saveImage = true;
if (!is_array($uploadFile)) {
// #todo handle no upload present
$save = false;
}
if ($uploadFile['error'] || $uploadFile['size'] < 1) {
// #todo handle upload error
$save = false;
}
if (!is_uploaded_file($uploadFile['tmp_name'])) {
// #todo handle potential malicious attack
$save = false;
}
if (!is_array($uploadImage)) {
// #todo handle no upload present
$saveImage = false;
}
if ($uploadImage['error'] || $uploadImage['size'] < 1) {
// #todo handle upload error
$saveImage = false;
}
if (!is_uploaded_file($uploadImage['tmp_name'])) {
// #todo handle potential malicious attack
$saveImage = false;
}
// Prepare the temporary destination path
//$config = & JFactory::getConfig();
//$fileDestination = $config->getValue('config.tmp_path'). DS . JFile::getName($uploadFile['tmp_name']);
// Move uploaded file
if($save)
{
$this->deleteLogo($data['oldLogo']);
$fileDestination = 'images/stories/members/' . $data['id'] . '-' . $uploadFile['name'];
$uploaded = JFile::upload($uploadFile['tmp_name'], $fileDestination);
}
if($saveImage)
{
$this->deleteLogo($data['oldImage']);
$fileDestination = 'images/stories/members/image/' . $data['id'] . '-' . $uploadImage['name'];
$uploadedImage = JFile::upload($uploadImage['tmp_name'], $fileDestination);
}
}
