Uploading video from iPad to server with AIR for iOS
8 years ago
In this part 2 post following on from Record and play back video with AIR for iOS on iPad I will show you how to take your freshly recorded video and upload it to a web server using PHP.
Assuming you have a MovieClip or some other button labeled ‘uploadbtn’ you first need to add a click event handler to it to trigger the upload.
1 | uploadbtn.addEventListener(MouseEvent.CLICK, onUpload); |
Now for the click handler:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | function onUpload(e:MouseEvent):void { // create a URLRequest for the PHP file on you server (we'll get to the PHP later) var URLrequest:URLRequest = new URLRequest("http://www.yourdomain.com/uploadFile.php"); // videoFile is a File object we created in the last post which references the recorded video // attach the various listeners for errors, progress, complete videoFile.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, uploadDataComplete); videoFile.addEventListener(ProgressEvent.PROGRESS, progressHandler); videoFile.addEventListener(IOErrorEvent.IO_ERROR, handleError); videoFile.addEventListener(Event.COMPLETE, completeHandler); // call upload on the File object and pass in the URLRequest videoFile.upload(URLrequest); } |
Now we can create the handlers for the attached listeners:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | function progressHandler(e:ProgressEvent):void { // just tracing the percentage of progress - you could show it in a progress bar trace("Uploading... " + Math.ceil(100 * (e.bytesLoaded / e.bytesTotal)) + "%"); } function completeHandler(e:Event):void { // upload process is complete trace(videoFile.name + " has been uploaded.\n"); } function uploadDataComplete(e:DataEvent):void { //everything is complete, trace the message returned from the PHP script which is in XML format var xml:XML = new XML(e.data); trace(xml.message); } function handleError(e:IOErrorEvent):void { // simple error handler traces the error trace("Upload Error:" + e.text); } |
That is all that is required for the ActionScript side of things. Now for the PHP script. This is a very basic script and you should provide some security and validation on any production code.
All you need to do is save this into a blank PHP file and upload it to your server to the location matching the address in you URLRequest above.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | <?php // variable for return message $message = ""; // the directory to place the video relative to this PHP script $directory = "uploads/"; // get the number of files already in the directory and increment the number for the new one // video from the iPad is always .MOV format $fileCount = count (glob ($directory."*.MOV")); $newName = $directory."video" . ( $fileCount + 1) . ".MOV"; // move uploaded file with new name into directory specified above if (move_uploaded_file($_FILES["Filedata"]["tmp_name"], $newName)){ // create a successful message if all went ok $message = "<result><status>OK</status><message>$file_name uploaded successfully.</message></result>"; }else{ // create a failed message if something went wrong $message = "<result><status>FAIL</status><message>$file_name did not upload successfully.</message></result>"; } echo $message; ?> |
That is all that’s required to upload a video from the iPad to a web server. It is surprisingly simple for how hard it was for me to work out.
I hope this helps somebody out!
