I am using Google drive sdk. I am using following code
$drive_service = new Google_Service_Drive($client);
$results = $drive_service->files->listFiles();
$items = $results->getItems();
foreach($items as $listItem){
$url[] = $listItem['selfLink'];
}
echo "<pre>"; print_r($url); exit;
There url shows all links.
Make use of the client libraries Google has provided for various languages to download files from Google Drive. Assuming that you are using PHP to serve this purpose, this is a nice quickstart guide for PHP developers to embed library to their project and complete the setup. This would involve authentication.
Finally you can use this code to download files from Google Drive using this code:
function downloadFile($service, $file) {
$downloadUrl = $file->getDownloadUrl();
if ($downloadUrl) {
$request = new Google_Http_Request($downloadUrl, 'GET', null, null);
$httpRequest = $service->getClient()->getAuth()->authenticatedRequest($request);
if ($httpRequest->getResponseHttpCode() == 200) {
return $httpRequest->getResponseBody();
} else {
// An error occurred.
return null;
}
} else {
// The file doesn't have any content stored on Drive.
return null;
}
}

I want to display a download link inside a WordPress widget. The file to be downloaded is located in the download subfolder of the site root, so that it can be uploaded via FTP. The name of the file and the text to be displayed for the download link shall be stored in a simple text file in the same folder.
Assuming WordPress is installed on www.mysite.com. The file name is setup_1_0.zip and the link display is Setup 1.0.
I am open to the file format how this information is stored as long as I can upload that file via FTP, too.
How can I embed this information inside a Custom HTML widget to get a valid download link with the text taken from that file?
How to automate the process of uploading latest software's build and download link creation in WordPress?
Based on your logic.
You are trying to automate the download process of your latest software version.
You don't want to update things manually and you just want to upload your latest build in the /download/ folder. (Only drop your latest version using FTP; that's all)
This is how I would do it:
Referencing those questions:
Get the latest file addition in a directory
How to force file download with PHP
I propose two solutions: First two separte codes, Second One inline code.
Just for educational purpose
First solution: Quick and short usage:
(You might need a way or a plugin to activate running PHP in Widget; this plugin helps PHP Code Widget)
<?php
$path = "download/";
$latest_ctime = 0;
$latest_filename = '';
$d = dir($path);
while (false !== ($entry = $d->read())) {
$filepath = "{$path}/{$entry}";
// could do also other checks than just checking whether the entry is a file
if (is_file($filepath) && filectime($filepath) > $latest_ctime) {
$latest_ctime = filectime($filepath);
$latest_filename = $entry;
}
}
echo 'Download '. $latest_filename . '';
?>
Second solution:
(Again, you might need a way or a plugin to activate running PHP in Widget; this plugin helps PHP Code Widget)
A) Create download.php in http://www.example.com/download.php
Add the following code:
<?php
$path = "download";
$latest_ctime = 0; //ctime stands for creation time.
$latest_filename = '';
$d = dir($path);
while (false !== ($entry = $d->read())) {
$filepath = "{$path}/{$entry}";
// could do also other checks than just checking whether the entry is a file
if (is_file($filepath) && filectime($filepath) > $latest_ctime) {
$latest_ctime = filectime($filepath);
$latest_filename = $entry;
}
}
// echo $latest_filename; un-comment to debug
$file_url = 'http://www.example.com/download/'.$latest_filename;
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"" . basename($file_url) . "\"");
readfile($file_url); // do the double-download-dance (dirty but worky)
?>
B) in your WordPress HTML Widget add the following code
<?php
$path = "download";
$latest_ctime = 0;
$latest_filename = '';
$d = dir($path);
while (false !== ($entry = $d->read())) {
$filepath = "{$path}/{$entry}";
// could do also other checks than just checking whether the entry is a file
if (is_file($filepath) && filectime($filepath) > $latest_ctime) {
$latest_ctime = filectime($filepath);
$latest_filename = $entry;
}
}
echo 'Download '. $latest_filename . '';
?>
Further explanation:
A) is responsiple for downloading the latest software build automatically.
B) is responsiple for displaying Latest build name and Creating the link.
Now, You only need to upload one file to your /download/ folder which is your latest build (setup_1_0.zip, setup_1_1.zip, setup_1_2.zip ...etc. The proposed solution will check creation date regardless of file's name.)
Important note: You can see that the latest file checker function is repeated twice; once in download.php and once in WordPress Widget. Because if we combine in one file we will get header already sent error.
Dose this answer your question please? Kindly feedback.
I have a file in Google Drive with id=0B3fqdol6s0bWZHV3RWpoV1gyWkk
And I created appscript to download it over a link automatically. The code looks like this
function doGet(e) {
return HtmlService.createHtmlOutput(downloader());
}
function downloader() {
var out = "<body onload='dllink.click()'>";
out +="<a id='dllink' href='https://drive.google.com/uc?export=download&id=0B3fqdol6s0bWZHV3RWpoV1gyWkk'>wait will download automatically<a/>";
out +="</body>";
return out;
};
Then, I developed it as webapps so my friend can download it easily using link
https://script.google.com/macros/s/AKfycbzzToo8gwgdj30FBLrjA1izcfv4rddjW6VClaEGuNXAqZAkIH7S/exec
It's working perfect on PC browser, but sadly, It can't work on mobile phone browser which doesn't support handle onload event or javascript.
So, is there any solution to make an appscript download a file based on its id automatically?
Try it by using an iFrame:
function doGet(e) {
return HtmlService.createHtmlOutput(downloader());
}
function downloader() {
var out = "<iframe width=\"1\" height=\"1\" frameborder=\"0\" src=\"https://drive.google.com/uc?export=download&id=0B3fqdol6s0bWZHV3RWpoV1gyWkk\"></iframe>";
return out;
};

Since I am unable to capture browser window close event using the GoogleWebAuthorizationBroker.AuthorizeAsync API, I followed this link (http://www.daimto.com/google-api-and-oath2/) to create an embedded browser and authenticate the user. I am unable to continue further to use the access token to upload a file in google drive. Is there any example available to continue from the above link to upload/download a file from Google Drive.
Regards,
Amrut
From the same author, there is a documentation how to upload/ download files to Google Drive.
Like with most of the Google APIs you need to be authenticated in order to connect to them. To do that you must first register your application on Google Developer console. Under APIs be sure to enable the Google Drive API and Google Drive SDK, as always don’t forget to add a product name and email address on the consent screen form.
Make sure your project is at least set to .net 4.0.
Add the following NuGet Package
PM> Install-Package Google.Apis.Drive.v2
In order to download a file we need to know its file resorce the only way to get the file id is from the Files.List() command we used earlier.
public static Boolean downloadFile(DriveService _service, File _fileResource, string _saveTo)
{
if (!String.IsNullOrEmpty(_fileResource.DownloadUrl))
{
try
{
var x = _service.HttpClient.GetByteArrayAsync(_fileResource.DownloadUrl );
byte[] arrBytes = x.Result;
System.IO.File.WriteAllBytes(_saveTo, arrBytes);
return true;
}
catch (Exception e)
{
Console.WriteLine("An error occurred: " + e.Message);
return false;
}
}
else
{
// The file doesn't have any content stored on Drive.
return false;
}
}
Using _service.HttpClient.GetByteArrayAsync we can pass it the download url of the file we would like to download. Once the file is download its a simple matter of wright the file to the disk.
Remember from creating a directory in order to upload a file you have to be able to tell Google what its mime-type is. I have a little method here that try’s to figure that out. Just send it the file name. Note: When uploading a file to Google Drive if the name of the file is the same name as a file that is already there. Google Drive just uploads it anyway, the file that was there is not updated you just end up with two files with the same name. It only checks based on the fileId not based upon the file name. If you want to Update a file you need to use the Update command we will check that later.
public static File uploadFile(DriveService _service, string _uploadFile, string _parent) {
if (System.IO.File.Exists(_uploadFile))
{
File body = new File();
body.Title = System.IO.Path.GetFileName(_uploadFile);
body.Description = "File uploaded by Diamto Drive Sample";
body.MimeType = GetMimeType(_uploadFile);
body.Parents = new List() { new ParentReference() { Id = _parent } };
// File's content.
byte[] byteArray = System.IO.File.ReadAllBytes(_uploadFile);
System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);
try
{
FilesResource.InsertMediaUpload request = _service.Files.Insert(body, stream, GetMimeType(_uploadFile));
request.Upload();
return request.ResponseBody;
}
catch (Exception e)
{
Console.WriteLine("An error occurred: " + e.Message);
return null;
}
}
else {
Console.WriteLine("File does not exist: " + _uploadFile);
return null;
}
}
I have a problem of my file uploading feature attached into my webapp. code is working perfectly in my localhost but not in the real server which i was uploaded already. and i was changed the directory permission to writable.
if ($model->load(Yii::$app->request->post()))
{
$session = Yii::$app->session;
$user_id = $session->get('role');
//get the instance of the uploaded file
$imageName = $model->Fname."_".$model->Lname;
$model->file = UploadedFile::getInstance($model, 'file');
if($model->file)
{
//SHA512 base password encription
$model->password = crypt($model->repeatpassword,'$6$rounds=1212$16charactersalt');
//save image pathe to db
$model->image = 'uploads/profile_image/'.$imageName.'.'.$model->file->extension;
$model->role = $user_id;
$model->save();
$model->file->saveAs( 'uploads/profile_image/'.$imageName.'.'.$model->file->extension );
}
//return $this->redirect(['index']);
return $this->goHome();
}
I think there is not any issue in your Yii2 code.
It may be an issue of PHP configuration.
File Info extension is enabled by default as of PHP 5.3.0
Windows users must include the bundled php_fileinfo.dll DLL file in php.ini to enable this extension.
Please visit below link for more details.
http://php.net/manual/en/fileinfo.installation.php
You need just uncomment in your php.ini this line:
extension=php_fileinfo.dll
i am trying to build a google earth view showing cities, but i stuck with the kml parser geoxml3. I have a javascript building a google map at first showing the locations i want. this works fine. I call the function from a php script providing it an address and kml file reference from database. The function builds the map, sets a flag 'map_finished' as a control flag when all ran fine and calls the build google earth view function.
// Get maps and earth from google
google.load( 'maps', '2.s', {'other_params': 'sensor=true'} );
google.load( 'earth', '1' );
//Google Earth Initializer
function initObjectEarth() {
// Check if Google Earth plugin is installed
if( gm_loaded ) {
this.ge_plugin_installed = google.earth.isInstalled();
if( this.ge_plugin_installed ) {
google.earth.createInstance( 'inmap', geSuccessCallback, geFailureCallback );
ge_loaded = true;
} else {
alert( 'Your Browser has not yet installed the Google Earth plugin.
We recommend installing it to use all features!' );
return false;
}
}
}
// Success handler
function geSuccessCallback( object ) {
this.ge = object;
this.ge.getWindow().setVisibility( true );
this.kmlParser = new geoXML3.parser();
}
// Error handler
function geFailureCallback( object ) {
alert( 'Error: ' + object );
}
The geoxml parser uses the ProjectedOverlay class. Both libraries are loaded into document head. When the parser is getting instatiated it requests a ProjectedOverlay instance. This class throws a
Error: **google.maps is undefined**
error in firebug for the following statement
ProjectedOverlay.prototype = new google.maps.OverlayView();
In my script file i have declared vars including
var gm //for google map
var ge //for google earth
gm is set in the function that builds the google map.
I wonder how to fix this issue. I tried the getProjection() thing i found in web as well as
ProjectedOverlay.prototype = new google.maps.OverlayView().prototype;
with no success. This topic is absolutely new to me and i cannot figure out how to fix it neither from the documentation of OverlayView nor from google search.
What did i forget or do wrong?
The call to the geoXML3 constructor is wrong, you must pass the google.maps object as a parameter (...hence the "google.maps is undefined" error).
this.kmlParser = new geoXML3.parser({map: gm}); // gm for google map
