Actionscript multiple file upload, with parameter passing is not working
- by Metropolis
Hey everyone,
First off, I am very bad at flash/actionscript, it is not my main programming language.
I have created my own file upload flash app that has been working great for me up until this point. It uses PHP to upload the files and sends back a status message which gets displayed in a status box to the user.
Now I have run into a situation where I need the HTML to pass a parameter to the Actionscript, and then to the PHP file using POST. I have tried to set this up just like adobe has it on http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_communications_7.html without success.
Here is my Actionscript code
import fl.controls.TextArea;
//Set filters
var imageTypes:FileFilter = new FileFilter("Images (*.jpg, *.jpeg, *.gif, *.png)", "*.jpg; *.jpeg; *.gif; *.png");
var textTypes:FileFilter = new FileFilter("Documents (*.txt, *.rtf, *.pdf, *.doc)", "*.txt; *.rtf; *.pdf; *.doc");
var allTypes:Array = new Array(textTypes, imageTypes);
var fileRefList:FileReferenceList = new FileReferenceList();
//Add event listeners for its various fileRefList functions below
upload_buttn.addEventListener(MouseEvent.CLICK, browseBox);
fileRefList.addEventListener(Event.SELECT, selectHandler);
function browseBox(event:MouseEvent):void {
fileRefList.browse(allTypes);
}
function selectHandler(event:Event):void {
var phpRequest:URLRequest = new URLRequest("ajax/upload.ajax.php");
var flashVars:URLVariables = objectToURLVariables(this.root.loaderInfo);
phpRequest.method = URLRequestMethod.POST;
phpRequest.data = flashVars;
var file:FileReference;
var files:FileReferenceList = FileReferenceList(event.target);
var selectedFileArray:Array = files.fileList;
var listener:Object = new Object();
for (var i:uint = 0; i < selectedFileArray.length; i++) {
file = FileReference(selectedFileArray[i]);
try {
file.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, phpResponse);
file.upload(phpRequest);
}
catch (error:Error) {
status_txt.text = file.name + " Was not uploaded correctly (" + error.message + ")";
}
}
}
function phpResponse(event:DataEvent):void {
var file:FileReference = FileReference(event.target);
status_txt.htmlText += event.data;
}
function objectToURLVariables(parameters:Object):URLVariables {
var paramsToSend:URLVariables = new URLVariables();
for(var i:String in parameters) {
if(i!=null) {
if(parameters[i] is Array) paramsToSend[i] = parameters[i];
else paramsToSend[i] = parameters[i].toString();
}
}
return paramsToSend;
}
The flashVars variable is the one that should contain the values from the HTML file. But whenever I run the program and output the variables in the PHP file I receive the following.
//Using this command on the PHP page
print_r($_POST);
//I get this for output
Array
(
[Filename] => testfile.txt
[Upload] => Submit Query
)
Its almost like the parameters are getting over written or are just not working at all.
Thanks for any help,
Metropolis
