sendPhoto to upload Photo not working

Question

I am trying to build a telegram bot, but the trouble is associated with the change in php functions due newer php 5.6.

Below is the basic code for it I found, accommodating changes in php 5.6.

      #$filePhoto = curl_file_create($filepath, 'image/jpg', 'heInternet');  //**LINE 39**
      $filePhoto = new CURLFile($filepath, 'image/jpg', 'heInternet');  //**LINE 40**
      //$texto = $_POST['msg'];
      $content = array(
          'chat_id' => "@BugTheInternet",
          'photo' => $filePhoto
      );

      //curl required to post
      $ch = curl_init();

      curl_setopt($ch, CURLOPT_URL, $url);
      curl_setopt($ch, CURLOPT_POST, true);
      curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false); // required as of PHP 5.6.0
      curl_setopt($ch, CURLOPT_POSTFIELDS, $filePhoto);  //**LINE 53**
      curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);  //fix http://unitstep.net/blog/2009/05/05/using-curl-in-php-to-access-https-ssltls-protected-sites/

      // receive server response ...
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

      $server_output = curl_exec ($ch);

Here is the Error I get:

Deprecated: curl_setopt(): The usage of the @filename API for file uploading is deprecated. Please use the CURLFile class instead in C:\xampp somewhere\somefile.php on line 53

When I change the $content to $filePhoto in line 53. It runs and Telegram server sends a messages in JSON. Server Reply:

"{"ok":false,"error_code":400,"description":"Error: Bad Request: there is no photo in request"}"

I have searched internet for hours, finding solutions. BTW, two ways suggested for PHP 5.6 that I am using, it is in line 39, 40.

Please help me if you have come across this or otherwise. thank you.

you should include your code in text format, should visitors to the question have to fix something, rather than retyping everything. — Funk Forty Niner, Nov 05 '15 at 03:48
TBH, I don't know about CURL very much, but I do know about uploading files in PHP. What I know is that it requires a valid enctype when handling files. Whether CURL does this automatically, I couldn't say, but as I went through some documentation, it looks as if it does. Have a look at this Q&A on Stack http://stackoverflow.com/questions/4223977/send-file-via-curl-from-form-post-in-php see if that helps. — Funk Forty Niner, Nov 05 '15 at 03:55
That is good. But my question here is little different than that. — Rahul Bali, Nov 05 '15 at 03:58
Ah ok. Well let's see if someone else picks up on your question. — Funk Forty Niner, Nov 05 '15 at 04:00
Actually, I found a mistake of yours: you pass `$filePhoto` to **CURLOPT_POSTFIELDS**, but you should pass a `$content` instead. — retif, Nov 10 '15 at 11:36
Yes, and I used $content to CURLOPT_POSTFIELDS, this shows the error 400. As I told in the question, about the second error. — Rahul Bali, Nov 10 '15 at 16:44

Have you tried to send it hardcore way like this?

$ch = curl_init("https://api.telegram.org/bot<token>/sendPhoto&chat_id=<chatID>&photo=<path/to/your/image>");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
curl_exec($ch);
curl_close ($ch);

Firstly I used POSTFIELDS and other correct stuff for cURL as well when sending message, but it wouldn't work for me. So I hardcored it like example above and it just worked.

you should remove

'chat_id' => "@BugTheInternet",

from $content and add chat_id to curl url because

PHP's cURL library dies returning the error message "failed creating formpost data" when trying to use an array that contains a value starting with '@'. If the array is changed to a string in URL encoded like format, the problem does not occur. refrence : https://bugs.php.net/bug.php?id=50060

And how do you suggest I do that? By making an Array variable? – Rahul Bali Jan 31 '16 at 07:24

After wasting a full hour on this myself years after this post I'm sharing how I got it working:

  function json($url, array $fields) {
    $ch = curl_init($url);
    $ok = 1;
    $ok &= curl_setopt($ch, CURLOPT_ENCODING, 'UTF-8');
    $ok &= curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    $ok &= curl_setopt($ch, CURLOPT_AUTOREFERER, true);
    $ok &= curl_setopt($ch, CURLOPT_TIMEOUT, 120);
    $ok &= curl_setopt($ch, CURLOPT_HTTPHEADER, [
      "Accept: application/json"
    ]);
    $ok &= curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $ok &= curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    $ok &= curl_setopt($ch, CURLOPT_HTTPHEADER, ["Content-Type:multipart/form-data"]);
    if ($ok !== 1) {
      user_error("curl_setopt failed");
    }

    $res = curl_exec($ch);
    if ($res === false) {
      var_dump($res);
      user_error(curl_error($ch));
    }
    $code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);

    if ($res === false) {
      user_error('curl_exec fail');
    }

    $json = json_decode($res, true);
    if (! is_array($json)) {
      print_r($res);
      user_error("http_json::failed decoding");
    }
    return $json;
}

$f = new \CurlFile("/path/to/file.jpg", 'image/jpeg', 'filename.jpg');

$args = [
  "photo" => $f,
  "chat_id" => $group,
  "caption" => "Hello world"
];
$url = "https://api.telegram.org/bot$token/sendPhoto";
var_dump( json($url, $args) );

This is on PHP7, the trick seems to be two things:

Content-Type:multipart/form-data
Using \CurlFile
