I am trying to store heavy image through the laravel queue as follows because i dont want my user to wait until file gets stored:
This code is in controller
if($request->hasfile('featuringPhoto'))
{
$prefixFilename = date("Y-m-d-H-i-s");
$coverFilename = $prefixFilename.$request->featuringPhoto->getClientOriginalName();
ProceessFiles::dispatch($request->featuringPhoto->getRealPath(),$coverFilename);
}
else
{
$coverFilename4 = NULL;
}
Below code is in job
protected $files, $filename;
public function __construct($files,$filename)
{
$this->files= $files;
$this->filename = $filename;
}
public function handle()
{
if($this->files){
$coverFilename = $prefixFilename.$this->filename;
$img = file_get_contents($this->files);
$img->storeAs('images/photosUploadedByUser', $coverFilename, 'public');
}
}
It Gives me an error saying Call to a member function storeAs() on string
I tried this solution from stack but didnt work
Any suggestion will be appreciated.Thank you.
I think it is wrong to assume you are gonna save a lot time by executing the save operation in a queue, also because you are already fetching it from the web server. Queues will with scaling often be moved to worker servers and with this approach this will not work.
In the spirit of the question, stackoverflow and to explain to you what is not working. file_get_contents() returns the content of the file as a string. So to fix your problem, you should just store the results of that. You obviously can not call methods on strings.
$coverFilename = $prefixFilename.$this->filename;
$img = file_get_contents($this->files);
Storage::put('images/photosUploadedByUser/' . $coverFilename, $img);

I am performing SSH in Laravel whereby I connect to another server and download a file. I am using Laravel Collective https://laravelcollective.com/docs/5.4/ssh
So, the suggested way to do this is something like this
$result = \SSH::into('scripts')->get('/srv/somelocation/'.$fileName, $path);
if($result) {
return $path;
} else {
return 401;
}
Now that successfully downloads the file and moves it to my local server. However, I am always returned 401 because $result seems to be Null.
I cant find much or getting the result back from the SSH. I have also tried
$result = \SSH::into('scripts')->get('/srv/somelocation/'.$fileName, $path, function($line){
dd( $line.PHP_EOL);
});
But that never gets into the inner function.
Is there any way I can get the result back from the SSH? I just want to handle it properly if there is an error.
Thanks
Rather than rely on $result to give you true / false / error, you can check if the file was downloaded successfully in another way:
// download the file
$result = \SSH::into('scripts')->get('/srv/somelocation/'.$fileName, $path);
// see if downloaded file exists
if ( file_exists($path) ) {
return $path;
} else {
return 401;
}
u need to pass file name also like this in get and put method:
$fileName = "example.txt";
$get = \SSH::into('scripts')->get('/remote/somelocation/'.$fileName, base_path($fileName));
in set method
$set = \SSH::into('scripts')->set(base_path($fileName),'/remote/location/'.$fileName);
in list
$command = SSH::into('scripts')->run(['ls -lsa'],function($output) {
dd($output);
});
I want to load datafixtures with DoctrineFixturesBundle with images but I don't know how to make it work.
I tried this one :
public function load(ObjectManager $manager)
{
$imageGrabTail = new Image();
$imageGrabTail->setTrick($this->getReference('grab-tail'));
$imageGrabTail->setUpdatedAt(new \DateTimeImmutable());
$file = new UploadedFile($imageGrabTail->getUploadDir() . '/63.jpeg', 'Image1', null, null, null);
$imageGrabTail->setFile($file);
$manager->persist($imageGrabTail);
$manager->flush();
}
My method getUploadDir():
public function getUploadDir()
{
return 'uploads/img';
}
But I have an error :
[Symfony\Component\HttpFoundation\File\Exception\FileNotFoundException]
The file "uploads/img/63.jpeg" does not exist
My file 63.jpeg exists on this folder.
Is there someone who can explain to me why it's not working ?
Thanks !
This object UploadedFile is for file that are upload through a request. Here there is no request, so you have to use get_file_contents() function in order to access your data.
Try this function and tell us the result of it.
To solve it I've just followed this thread
How would you add a file upload to a Symfony2 DataFixture?
I have a service which uses a Yahoo! Finance table yahoo.finance.xchange. This morning I noticed it has stopped working because suddenly Yahoo! started to return an error saying:
{
"error": {
"lang": "en-US",
"description": "No definition found for Table yahoo.finance.xchange"
}
}
This is the request URL. Interesting fact: if I try to refresh the query multiple times, sometimes I get back a correct response but this happen very rarely (like 10% of the time). Days before, everything was fine.
Does this mean Yahoo API is down or am I missing something because the API was changed? I would appreciate any help.
Since I have the same problem and that it started today too, that others came to post exactly in the same time as well, and that it still works most of the time, the only explanation I can find is that they have some random database errors on their end and we can hope that this will be solved soon. I also have a 20% rate of failures when refreshing the page of the query.
My guess is that they use many servers to handle the requests (let's say 8) and that one of them is empty or doesn't have that table for some reasons so whenever it directs the query to that server, the error is returned.
Temporary solution: Just modify your script to retry 3-4 times. That did it for me because among 5 attempts at least one succeeds.
I solve this issue by using quote.yahoo.com instead of the query.yahooapis.com service. Here's my code:
function devise($currency_from,$currency_to,$amount_from){
$url = "http://quote.yahoo.com/d/quotes.csv?s=" . $currency_from . $currency_to . "=X" . "&f=l1&e=.csv";
$handle = fopen($url, "r");
$exchange_rate = fread($handle, 2000);
fclose($handle );
$amount_to = $amount_from * $exchange_rate;
return round($amount_to,2);
}
EDIT the above no longer works. At this point, lets just forget about yahoo lol Use this instead
function convertCurrency($from, $to, $amount)
{
$url = file_get_contents('https://free.currencyconverterapi.com/api/v5/convert?q=' . $from . '_' . $to . '&compact=ultra');
$json = json_decode($url, true);
$rate = implode(" ",$json);
$total = $rate * $amount;
$rounded = round($total);
return $total;
}
Same error, i migrate to http://finance.yahoo.com
Here is C# example
private static readonly ILog Log = LogManager.GetCurrentClassLogger();
private int YahooTimeOut = 4000;
private int Try { get; set; }
public decimal GetRate(string from, string to)
{
var url =
string.Format(
"http://finance.yahoo.com/d/quotes.csv?e=.csv&f=sl1d1t1&s={0}{1}=X", from, to);
var request = (HttpWebRequest)WebRequest.Create(url);
request.UseDefaultCredentials = true;
request.ContentType = "text/csv";
request.Timeout = YahooTimeOut;
try
{
using (var response = (HttpWebResponse)request.GetResponse())
{
var resStream = response.GetResponseStream();
using (var reader = new StreamReader(resStream))
{
var html = reader.ReadToEnd();
var values = Regex.Split(html, ",");
var rate = Convert.ToDecimal(values[1], new CultureInfo("en-US"));
if (rate == 0)
{
Thread.Sleep(550);
++Try;
return Try < 5 ? GetRate(from, to) : 0;
}
return rate;
}
}
}
catch (Exception ex)
{
Log.Warning("Get currency rate from Yahoo fail " + ex);
Thread.Sleep(550);
++Try;
return Try < 5 ? GetRate(from, to) : 0;
}
}
I've got the same issue.
I need exchange rates in my app, so I decided to use currencylayer.com API instead - they give 168 currencies, including precious metals and Bitcoin.
I've also written a microservice using webtask.io to cache rates from currencylayer and do cross-rate calculations.
And I've written a blog post about it 🤓
Check it out if you want to run your own microservice, it's pretty easy 😉
I found solution, in my case, just change http to https and everything works fine.
This listener sends me reports on all kinds of exceptions that occur on the website. Sometimes I get reports of images that have been deleted but are still consulted by search engines and others.
I want to do, instead of displaying an error message " 404 Not Found " return the correct image. To do this I created a database table that stores the old links and new links of the images that have been deleted, moved or changed its name.
then, this listener find in db the links to fallen and gets the new links of images . The goal is to return the image as http-response with header content-type as image.
My code is:
class ExceptionListener
{
private $service_container;
private $router;
function __construct(Container $service_container, $router){
$this->service_container = $service_container;
$this->router = $router;
}
public function onKernelException(GetResponseForExceptionEvent $event){
$exception = $event->getException();
$request = $this->service_container->get('request');
...
$document_root = $request->server->get('DOCUMENT_ROOT');
$filename = realpath($document_root . '/'. '/path/to/new_image.jpg');
$response = new \Symfony\Component\HttpFoundation\Response();
$response->headers->set('Content-type', 'image/jpeg');
$response->headers->set('Content-Disposition', 'inline; filename="' . basename($filename) . '";');
$response->headers->set('Content-length', filesize($filename));
$response->sendHeaders();
$response->setContent(file_get_contents($filename));
return $response;
...
}
}
The following error occurs:
In the browser you can see a small box , it is as if trying to show the image but the image source could not be obtained . But if the same code is testing on controller , its working properly and the image is displayed .
What can I do to return image from a listener ? thanks
There's few things wrong about the code snippet from your question.
Firstly, you should never use the request service. It's deprecated since Symfony 2.4 and was removed in Symfony 3.0. Use the request stack (request_stack) instead.
Secondly, do not send the response yourself, but let the framework do it. Symfony events system is designed for flexibility (see the docs). In your case it's enough to set the response on the event object.
Finally, you don't need the service container to access the request at all, as it's available on the event.
Moreover, instead of the standard Response class you can use the BinaryFileResponse. It's purpose is to serve files (have a look at the docs).
You can greatly simplify your listener:
use Symfony\Component\HttpFoundation\BinaryFileResponse;
class ExceptionListener
{
private $router;
function __construct($router)
{
$this->router = $router;
}
public function onKernelException(GetResponseForExceptionEvent $event)
{
$exception = $event->getException();
// request is avialable on the event
$request = $event->getRequest();
// ...
$file = 'path/to/file.txt';
$response = new BinaryFileResponse($file);
// ... set response parameters ...
// finally, set the response on your event
$event->setResponse($response);
}
}
I am trying to get the new PDO driver running in Code Igniter 2.1.1 in (to start with) the local (Mac OS 10.7) copy of my app.
I initially coded it using Active Record for all db operations, and I am now thinking I want to use PDO prepared statements in my model files, going forward.
I modified 'application/config/database.php' like so:
(note a couple minor embedded questions)
[snip]
$active_group = 'local_dev';
$active_record = TRUE;//<---BTW, will this need to stay TRUE to make CI sessions work? For better security, don't we want db-based CI sessions to use PDO too?
//http://codeigniter.com/user_guide/database/configuration.html:
//Note: that some CodeIgniter classes such as Sessions require Active Records be enabled to access certain functionality.
//this is the config setting that I am guessing (?) is my main problem:
$db['local_dev']['hostname'] = 'localhost:/tmp/mysql.sock';
// 1.) if $db['local_dev']['dbdriver']='mysql', then here ^^^ 'localhost:/tmp/mysql.sock' works, 2.) but if $db['local_dev']['dbdriver']='pdo', then it fails with error msg. shown below.
$db['local_dev']['username'] = 'root';
$db['local_dev']['password'] = '';
$db['local_dev']['database'] = 'mydbname';
$db['local_dev']['dbdriver'] = 'pdo';
$db['local_dev']['dbprefix'] = '';
$db['local_dev']['pconnect'] = TRUE;
$db['local_dev']['db_debug'] = TRUE;//TRUE
$db['local_dev']['cache_on'] = FALSE;
$db['local_dev']['cachedir'] = '';
$db['local_dev']['char_set'] = 'utf8';
$db['local_dev']['dbcollat'] = 'utf8_general_ci';
$db['local_dev']['swap_pre'] = '';
$db['local_dev']['autoinit'] = TRUE;
$db['local_dev']['stricton'] = FALSE;
[snip]
With the above config., as soon as I load a controller, I get this error message:
Fatal error: Uncaught exception 'PDOException' with message 'could not find driver' in
/Library/WebServer/Documents/system/database/drivers/pdo/pdo_driver.php:114 Stack trace: #0

I tried swapping out the 'pdo_driver.php' file from the one on github, as per this:
http://codeigniter.com/forums/viewthread/206124/
...but that just generates other errors, not to mention is disturbing to a newbie who does not want to touch the system files if at all possible.
This thread also seems to imply the need to be hacking the 'pdo_driver.php' system file:
CodeIgniter PDO database driver not working
It seems odd to me, though, that (someone thought that) a hack to a system file is needed to make PDO work in CI v.2.1.1, huh?
Thanks for any suggestions I can try.
I don't know if this might be helpful for you since you already started using the CI functions, but I made my own library for PDO with sqlite and just auto load it. My needs were simple, so it serves its purpose.

thanks to the noob thread http://codeigniter.com/forums/viewthread/180277/ (InsiteFX’s answer)..
I figured out the below seems to work (need to test more to be 100%... but at least the error messages are gone:
$db['local_dev']['hostname'] = 'mysql:host=127.0.0.1';
