Can't access to json Obj when uploading an image

[vitalijalbu]

When i try to upload an image i would like to get only hash ID and save it into DB. But response object can't be accessible.

what do you mean you can't access the json object? When you upload an image

eg via curl: curl -s -F "file=@/path/to/your/image.jpg" https://pictshare.net/api/upload.php you get the answer in form of a JSON object that defines the hash and path.

{
  "status": "ok",
  "hash": "e17o3a.jpg",
  "filetype": "jpeg",
  "url": "https://pictshare.net/e17o3a.jpg"
}

yes right, i get that json response but i can't access to hash and then save into DB. for example i have this global function that helps me to upload an image: public function upload_img($file) {

    $ch = curl_init();
    $cfile = new CURLFile($file);

    $data = array("file"=>$cfile);

    $url = "http://cdn.ceebo.com/api/upload.php";
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
    $response = curl_exec($ch);
    print_r($response['url']);
    if($response === true)
    {
        $output = $response['hash'];
    }
    else
    {
        $output = "error occured";
    }

  return $output;
}

Now i'd like to get only hash ID from $output, but is returns NULL

To get the response using the curl php extension you need to set returntransfer to true.

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

Also, because the answer from the server is a JSON object you'll have to parse it first before being able to use it as an array

Try this

$ch = curl_init();
$cfile = new CURLFile($file);

$data = array("file"=>$cfile);

$url = "http://cdn.ceebo.com/api/upload.php";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = json_decode(curl_exec($ch),true);
var_dump($response]);
