Uploading a image in php with curl

In the latest years we (php programmers) have spent a lot of time  behind classes and frameworks ,  making all our repetitive tasks available in simple and understandable forms like :

$image = new Image('/var/www/image.jpg');
$image->upload('http://www.somesite.com/upload.php');

However , when the Image class can not be used ,  most of use will google for  “how to upload an image with php curl”.

The following snippet of code can be used to upload a image:

$url = 'http://somesite.com/upload.php;
$file = 'image.jpg';
$curl  = curl_init($url);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POSTFIELDS,
             array('image' => "@$file;type=image;type=image/jpeg"));
$resp = curl_exec($curl);

Note the @ before the file. It will extract the binary contents of file , so be wary of your php memory limit.

    Hey,

    I’m using the exact same code, but I keep on getting “failed to create formpost data”. I’ve checked the photo path and i’m pretty sure it perfectly right…

    $fileToCopy = $_FILES["btnBrowse"]["tmp_name"];
    $fileName = $_FILES["btnBrowse"]["name"];

    $copyTemp = “temppool/testimage.jpg”;
    @copy($fileToCopy, $copyTemp) or die(”can’t copy “.$fileName.” to “.$copyTemp);

    //print $_FILES["btnBrowse"]["type"];

    $api_sig = md5(”5ed58b4c4fa78297″.”api_key”.”fffaf8c8e4c4b7f016c67b8e03061305″.”auth_token”.$_SESSION["flickrAuthToken"]);

    $params = array(
    “api_key” => “fffaf8c8e4c4b7f016c67b8e03061305″,
    “auth_token” => $_SESSION["flickrAuthToken"],
    “api_sig” => $api_sig,
    “photo” => “@$copyTemp;type=”.$_FILES["btnBrowse"]["type"]
    );

    ksort($params);

    $curlrequest = curl_init();
    curl_setopt($curlrequest, CURLOPT_URL, “http://api.flickr.com/services/upload/”);
    curl_setopt($curlrequest, CURLOPT_POST, true);
    curl_setopt($curlrequest, CURLOPT_HEADER, false);
    curl_setopt($curlrequest, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curlrequest, CURLOPT_POSTFIELDS, $params);

    Hey ,
    are you sure?
    what does var_export(is_file($copyTemp)) shows, just before $params declaration?
