I'm working on a ionic chat app where the user can upload a photo as part of their message. I'm looking for a way to upload the image to my webhost server so I can retrieve it later via a URL.
The problem is that I'm not able to get it to upload to my web server.
I'm using these two plugins:
- org.apache.cordova.file-transfer
- cordova-plugin-camera
When I run the app in xcode simulator and select a picture from the device photolibrary, the console gives me the following messages:
File Transfer Finished with response code 200void SendDelegateMessage(NSInvocation *): delegate (webView:runJavaScriptAlertPanelWithMessage:initiatedByFrame:) failed to return after waiting 10 seconds. main run loop mode: kCFRunLoopDefaultMode>SUCCESS: ""
This is the code I currently use:
app.controller('HomeController', function($rootScope, $scope, $cordovaCamera, $ionicActionSheet, $cordovaFileTransfer){ ...
// open PhotoLibrary
$scope.openPhotoLibrary = function() {
var options = {
quality: 100,
destinationType: Camera.DestinationType.FILE_URI,
sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
allowEdit: true,
encodingType: Camera.EncodingType.JPEG,
popoverOptions: CameraPopoverOptions,
saveToPhotoAlbum: false
};
$cordovaCamera.getPicture(options).then(function(imageData) {
//console.log(imageData);
//console.log(options);
var url = "http://mydomein.com/upload.php";
//target path may be local or url
var targetPath = imageData;
var filename = targetPath.split("/").pop();
var options = {
fileKey: "file",
fileName: filename,
chunkedMode: false,
mimeType: "image/jpg"
};
$cordovaFileTransfer.upload(url, targetPath, options).then(function(result) {
console.log("SUCCESS: " + JSON.stringify(result.response));
alert("success");
alert(JSON.stringify(result.response));
}, function(err) {
console.log("ERROR: " + JSON.stringify(err));
alert(JSON.stringify(err));
}, function (progress) {
// constant progress updates
$timeout(function () {
$scope.downloadProgress = (progress.loaded / progress.total) * 100;
})
});
}, function(err) {
// error
console.log(err);
});
}
This is my upload.php file:
<?php
// move_uploaded_file($_FILES["file"]["tmp_name"], $cwd . '/files/images/');
move_uploaded_file($_FILES["file"]["tmp_name"], "/files/images");
?>
After some digging around and lot's of trying I finally got it working.
This is the code I came up with:
// open PhotoLibrary
$scope.openPhotoLibrary = function() {
var options = {
quality: 50,
destinationType: Camera.DestinationType.FILE_URI,
sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
allowEdit: true,
encodingType: Camera.EncodingType.JPEG,
popoverOptions: CameraPopoverOptions,
saveToPhotoAlbum: false
};
$cordovaCamera.getPicture(options).then(function(imageData) {
//console.log(imageData);
//console.log(options);
var image = document.getElementById('tempImage');
image.src = imageData;
var server = "http://yourdomain.com/upload.php",
filePath = imageData;
var date = new Date();
var options = {
fileKey: "file",
fileName: imageData.substr(imageData.lastIndexOf('/') + 1),
chunkedMode: false,
mimeType: "image/jpg"
};
$cordovaFileTransfer.upload(server, filePath, options).then(function(result) {
console.log("SUCCESS: " + JSON.stringify(result.response));
console.log('Result_' + result.response[0] + '_ending');
alert("success");
alert(JSON.stringify(result.response));
}, function(err) {
console.log("ERROR: " + JSON.stringify(err));
//alert(JSON.stringify(err));
}, function (progress) {
// constant progress updates
});
}, function(err) {
// error
console.log(err);
});
}
And the code in upload.php on the domain server:
<?php
// if you want to find the root path of a folder use the line of code below:
//echo $_SERVER['DOCUMENT_ROOT']
if ($_FILES["file"]["error"] > 0){
echo "Error Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Uploaded file: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kilobytes<br />";
if (file_exists("/files/".$_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. No joke-- this error is almost <i><b>impossible</b></i> to get. Try again, I bet 1 million dollars it won't ever happen again.";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],"/var/www/vhosts/yourdomain.com/subdomains/domainname/httpdocs/foldername/images/".$_FILES["file"]["name"]);
echo "Done";
}
}
?>
the app I am building for a company had the same issue, what we did is we just posted the image to our server as a base64 string. Then you can simple pull the string from the database and display it in a div. We used the NgCordova camera and then just pass in the data from the takePhoto function.
$scope.takePhoto = function () {
$ionicScrollDelegate.scrollTop();
console.log('fired camera');
$scope.uploadList = false;
$ionicPlatform.ready(function() {
var options = {
quality: 100,
destinationType: Camera.DestinationType.DATA_URL,
sourceType: Camera.PictureSourceType.CAMERA,
allowEdit: false,
encodingType: Camera.EncodingType.PNG,
targetWidth: 800,
targetHeight: 1100,
popoverOptions: CameraPopoverOptions,
saveToPhotoAlbum: false
};
$cordovaCamera.getPicture(options).then(function (imageData) {
$ionicLoading.show({
template: 'Processing Image',
duration: 2000
});
$scope.image = "data:image/png;base64," + imageData;
if (ionic.Platform.isAndroid() === true) {
$scope.Data.Image = LZString.compressToUTF16($scope.image);
$scope.Data.isCompressed = 1;
} else {
$scope.Data.Image = $scope.image;
$scope.Data.isCompressed = 0;
}
if ($scope.tutorial) {
$scope.showAlert("Instructions: Step 3", '<div class="center">Now that you have taken a photo of the POD form, you must upload it to the server. Press the upload doc button in the bottom right of the screen.</div>');
}
$scope.on('')
}, function (err) {
console.log(err);
});
}, false);
};
$scope.UploadDoc = function () {
var req = {
method: 'POST',
url: ffService.baseUrlAuth + 'cc/upload',
headers: {
'x-access-token': ffService.token
},
data: $scope.Data
};
if ($scope.Data.Image === null || $scope.Data.Value === '') {
$scope.showAlert("Uh Oh!", '<div class="center">Please take a photo of your document before attempting an upload.</div>');
} else {
$http(req).success(function (data, status, headers, config) {
localStorage.setItem('tutorial', false);
$scope.tutorial = false;
$scope.getUploads($scope.PODOrder.OrderNo);
$scope.showAlert("Success!", '<div class="center">Your Document has been successfully uploaded!</div>');
$scope.uploadList = true;
}).error(function (data, status, headers, config) {
$rootScope.$broadcast('loading:hide');
$scope.showAlert("Something went wrong!", '<div class="center">Please make sure you have an internet connection and try again.</div>');
}).then(function(data, status, headers, config){
$scope.Data.Image = null;
});
}
};
