File upload using Flash Action Script 3 without PHP

Hi,

I need the code for AS3 to upload files... It shouldn't use PHP.

Thanks

 

I had to do a lot of searching and testing to figure out a way to allow users to upload images on the word associator, turns out the AS2 was is completely out as it's been replaced with a much easier method using file reference, but since there's not a lot of documentation out about it I thought I'd post my code if anyone else is having trouble searching for it as well.

First: define variables and import FileReference

import flash.net.FileReference;
flash.system.Security.allowDomain("http://localhost/");
var imageTypes:FileFilter = new FileFilter("Images (*.jpg)", "*.jpg"); // allow only jpg
var allTypes:Array = new Array(imageTypes);
var fileRef:FileReference = new FileReference();


Next, after clicking an upload button we need to open the browse box on the user's machine

function browseImages(e:MouseEvent) {
fileRef.addEventListener(Event.SELECT, selectHandler);
fileRef.browse(allTypes);
function selectHandler(e:Event) {
imageSelected = true;
myTextBox.text = fileRef.name;
// use the function to store a variable to let flash know you've selected an image
// it's also a good idea to have a text display of the filename the user selected
}
}


After clicking a submit button the function for calling the php uploader goes something like this:

function uploadImage() {
if(fileRef.size > 300000) {
trace("image size over 300kb");
} else {
var requestF:URLRequest = new URLRequest("http://www.yoursite.com/upload.php");
fileRef.upload(requestF);
fileRef.addEventListener(Event.COMPLETE, fileDone);
function fileDone(e:Event) {
sendWords("s", imagePath);
// use this to call another function to store the image path in a database if you want
}
}
}


Now for the PHP script, you will also need to set up 2 folders in your web directory "temporary" and "uimages".

$MAXIMUM_FILESIZE = 1024 * 300; // 300KB
$MAXIMUM_FILE_COUNT = 10; // keep maximum 10 files on server
echo exif_imagetype($_FILES['Filedata']);
if ($_FILES['Filedata']['size'] <= $MAXIMUM_FILESIZE)
{
move_uploaded_file($_FILES['Filedata']['tmp_name'], "./temporary/".$_FILES['Filedata']['name']);
$type = exif_imagetype("./temporary/".$_FILES['Filedata']['name']);
if ($type == 1 || $type == 2 || $type == 3)
{
rename("./temporary/".$_FILES['Filedata']['name'], "./uimages/".$_FILES['Filedata']['name']);
}
else
{
unlink("./temporary/".$_FILES['Filedata']['name']);
}
}
$directory = opendir('./uimages/');
$files = array();
while ($file = readdir($directory))
{
array_push($files, array('./uimages/'.$file, filectime('./uimages/'.$file)));
}
usort($files, sorter);
if (count($files) > $MAXIMUM_FILE_COUNT)
{
$files_to_delete = array_splice($files, 0, count($files) - $MAXIMUM_FILE_COUNT);
for ($i = 0; $i < count($files_to_delete); $i++)
{
unlink($files_to_delete[$i][0]);
}
}
print_r($files);
closedir($directory);

function sorter($a, $b)
{
if ($a[1] == $b[1]) { return 0; }
else { return ($a[1] < $b[1]) ? -1 : 1; }
}
?>
