Php Curl send File with data

Question

I need to upload 3 files along with variables in post data. This is what my call looks like -

$data['type1'] = new CurlFile($file1);
$data['type2'] = new CurlFile($file2);
$data['type3'] = new CurlFile($file3);

curl_setopt($ch, CURLOPT_POSTFIELDS, $data, "var1: $val1", "var2: $val2"); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data', "headkey: $headkeyValue"));

I am not able to get $app->request()->post('var1'); from slim framework. It is empty.

I am able to get the headkey from the Header as $app->request()->headers('headkey');
I am able to get the data in $_FILES

Here the sample curl request

$curlFile = curl_file_create($uploaded_file_name_with_full_path);
$post = array('val1' => 'value','val2' => 'value','file_contents'=> $curlFile );
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$your_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);

Don't forget to put the appropriate header.
You can also find good source here Curl File Upload to send file via CURL. Make sure that you are passing your file on file_contents key in above code.

Thanks looks like this worked. I was using some variables with the $data array, everything should go in the $data array then the _POST and _FILES resolves properly.

yes absolutely , so here instead of post will be data

You have different options to submit multidimensional data. Either you can submit json string by converting you data or break that in key value pair which can be transmitted as http data.

This is what I did in alignment to ssingh's answer:

$data['type1'] = new CurlFile($file1);
$data['type2'] = new CurlFile($file2);
$data['type3'] = new CurlFile($file3);

//New Code Added
$data['var1'] = "$val1";
$data['var2'] = "$val2";

//removed the trailing string
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

It's due to the fact that all files uploaded with HTTP POST method are in $_FILES global variable. That's why you cannot access files by this way

$app->request()->post('val1');

but you can by using $_FILES

$_FILES description

An associative array of items uploaded to the current script via the HTTP POST method. The structure of this array is outlined in the POST method uploads section.

@SSingh I've copied the code from author's post. I don't know why I got -1 if my answer is correct :).

Thanks for pointing out the error, I have corrected it. However I cannot change the server side code. I need to create the correct php curl request.
