I all,
I'm trying to upload an xls file using the HTML5 API.
I already have a script which is working开发者_如何转开发 great for images.
It's also working with an xls file except the fact that I can't open the file using excel once it has been uploaded... If I compare the size, the orignal file is 251 904 octets while the upload one is 251 911 octets. I don't know if that matter.
Here is what i've done :
Javascript:
reader = new FileReader();
reader.onloadend = function(evt) {
that.file = evt.target.result;
};
reader.readAsDataURL(file); // I've also try with readAsText but it's worse
the file is send using Sproutcore Framework:
SC.Request.postUrl(url).json()
.notify(this, 'fileUploadDidComplete', fileName)
.send({ fileName: fileName, file: file });
PHP:
$httpContent = fopen('php://input', 'r');
$json = stream_get_contents($httpContent);
fclose($httpContent);
$data = json_decode($json, true);
$file = base64_decode($data['file']);
$fileName = substr(md5(time().rand()), 0, 10).$data['fileName'];
$filePath = GX_PATH."/files/tmp/".$fileName;
$handle = fopen($filePath, "w");
fwrite ($handle, $file);
fclose($handle);
I hope somebody will help me to find what is wrong.
Thanks in advance.
EDIT:
I find another way which work on more browsers. I've discover FormData !
formData = new FormData();
formData.append("file", file);
SC.Request.postUrl(url).notify(this, 'formDataDidPost').send(formData);
This way, the PHP code is more simple :
$_FILES['file'];
I have done this using following method
$out = fopen($fileUploadPath ,"wb");
$in = fopen("php://input", "rb");
stream_copy_to_stream($in,$out);
This is just 3 methods I used to write the uploaded content to the server. Try it and see
