I have searched all over the internet on the possibility to upload a pdf file using php script. I tried all the suggestions given in this site and it didn't work.

try to print the type recongnized of your file in the else statement instead of simply printing "Upload failed".
echo ($_FILES["userfile"]["type"]);
Maybe the tyope recognized is not one belonging to the types specified in the if.
I have done this on the project I'm currently working on. Here is the upload code I use.
require_once $_SERVER['DOCUMENT_ROOT'] . 'upload.php';
// Initialize file path
define ('UPLOAD_PATH', $_SERVER['DOCUMENT_ROOT'] . pdfFolder/");
// list of valid extensions, ex. array("jpeg", "xml", "bmp")
$allowedExtensions = array("pdf", "xls");
// max file size in bytes
$sizeLimit = 10 * 1024 * 1024;
$uploader = new qqFileUploader($allowedExtensions, $sizeLimit);
$result = $uploader->handleUpload(UPLOAD_PATH, false);
if(sizeof($result['error']) == 0){
// do what you want on success
}
else{
echo "Error - " . $result['error'];

You could listen for when the file is selected client side and get the width using the FileReader API. I have done a fiddle: http://jsfiddle.net/t9mwfuoo/2/
$('.upload').on('change', function(e) {
var file = e.target.files[0];
var fr = new FileReader();
fr.readAsDataURL(file);
fr.onload = function(frEvent) {
var tmpImage = new Image();
tmpImage.src = frEvent.target.result;
tmpImage.onload = function() {
if (tmpImage.width <= 180) {
alert('Image width is equal to or less than 180 pixels');
} else {
alert('Image width is larger than 180 pixels');
}
}
}
});
This link will help you.
http://php.net/manual/en/function.imagesx.php
the function imagesx returns the width of an image.
<?php
echo imagesx($img); // returns the width
?>
For your code you have to use
<?php
$file_width = imagesx($_FILES['qqfile']);
?>
I hope this will help you.

so i want to add a watermark on images before save the image to destination folder, can anyone give me a help on this, ive try using a couple scripts but for sure i have no idea how implement this.
Look, save method in qqUploadedFileForm class, moves uploaded file to $path,
So, if I decide to explain easily, after if statement ends, you can get the uploaded file from $path and add your watermark using these tutorials:
Text-Watermark
Image-Watermark
NOTE:
Take a look to imagepng() or imagejpeg() syntax to find out how to replace prepared image.
You cal Also replace watermark-image to source-image by using copy('/address/to/watermark-image', '/address/to/source-image');
You might also want to consider: watermark-all-your-uploaded-images tutorial.
Im struggling with Valumx exellent Fileupload. Ive been using it for a couple of years, - and only recently realised that it doesnt work in IE9.
Ive found a couple of answers around here, - but cant seem to figure out how to implement it in my PHP project.
There should be an answer here: Valums file-uploader doesn't work under Internet Explorer 9
But I cant figure out where to put what, to make it work.
Can anyone help me, and write a Valums+IE9+PHP-for-dummies?
It seems that is IE cache issue, if you are using Ajax & GET, add timestamp value in the get parameters for the Ajax parameters, that will do the trick like this :
$.ajax({
url : "http:'//myexampleurl.php' + '?ts=' + new Date().getTime(),
dataType: "json",
contentType: "application/json; charset=utf-8",
.
.
//more stuff
When you download the Valums File Uploader package from GitHub you will also find that this package comes with a PHP example that I am dumping here:

I'm currently using Valum's File Uploader on Wamp and everything had been going smoothly until now. Inside the uploader's php file I made it save the uploaded file to the current user's folder by reading from the session data to get the current user. However, it is creating a new session everytime I call it for some unknown reason. I have checked the cookies and they return the correct session. I also checked the session_id() and it also returns the correct session. However, it always creates a new session for some reason. I even explicitly set the session id with the session_id() function. However, none of this works for some reason. It's returning the correct id but it doesn't save to the correct id. Anyone know why this is happening?
Below is the modified Uploader.php code.
<?php
//if (!empty($_COOKIE['PHPSESSID'])){
session_id($_COOKIE['PHPSESSID']);
session_start();
//}
if(isset($_SESSION['id'])){

fclose($input);

Update
I now see something a bit unusual. It seems like it's copying the session and leaving behind the old session file - just like what session_regnerate_id() does. However, I don't have that anywhere in my code.
I had the same problem, and in my case inserting this line...
ini_set('session.use_strict_mode', 0);
...right before session_start() solved it.
im having trouble trying to get the file to upload. the aim is it to create a directory struction based on the work id, but its not creating the folder or uploading the file but it is returning that it has succeeded but also failed, ive spent the past few day trying to fix it but to no avail, can anyone see what is wrong with it or point me in the right direction
