PHP Curl - Wistia API Upload - php

Question

I'm trying to upload a movie to the Wistia API by CURL (http://wistia.com/doc/upload-api).
It works fine using the following command line, but when I put it in PHP code, I just get a blank screen with no response:
$ curl -i -d "api_password=<YOUR_API_PASSWORD>&url=<REMOTE_FILE_PATH>" https://upload.wistia.com/
PHP Code:
<?php
$data = array(
'api_password' => '<password>',
'url' => 'http://www.mysayara.com/IMG_2183.MOV'
);
$chss = curl_init('https://upload.wistia.com');
curl_setopt_array($chss, array(
CURLOPT_POST => TRUE,
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_POSTFIELDS => json_encode($data)
));
// Send the request
$KReresponse = curl_exec($chss);
// Decode the response
$KReresponseData = json_decode($KReresponse, TRUE);
echo("Response:");
print_r($KReresponseData);
?>
Thanks.

For PHP v5.5.0 or later, here's a class for uploading to Wistia, from a LOCALLY STORED file.
Usage:
$result = WistiaUploadApi::uploadVideo("/var/www/mysite.com/tmp_videos/video.mp4","video.mp4","abcdefg123","Test Video", "This is a video upload demonstration");
The class:
#param $file_path Full local path to the file
#param $file_name The name of the file (not sure what Wistia does with this)
#param $project The 10 character project identifier the video will upload to
#param $name The name the video will have on Wistia
#param $description The description the video will have on Wistia
class WistiaUploadApi
{
const API_KEY = "<API_KEY_HERE>";
const WISTIA_UPLOAD_URL = "https://upload.wistia.com";
public static function uploadVideo($file_path, $file_name, $project, $name, $description='')
{
$url = self::WISTIA_UPLOAD_URL;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
$params = array
(
'project_id' => $project,
'name' => $name,
'description' => $description,
'api_password' => self:: API_KEY,
'file' => new CurlFile($file_path, 'video/mp4', $file_name)
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//JSON result
$result = curl_exec($ch);
//Object result
return json_decode($result);
}
}
If you don't have a project to upload into, leaving $project blank will NOT apparently force Wistia to create one. It will just fail. So you might have to remove this from the $params array if you don't have a project to upload to. I've not experimented to see what happens when you leave $name blank.

Your problem (and the difference between the command line and PHP implementation) is probably that you're JSON encoding the data in PHP, you should use http_build_query() instead:
CURLOPT_POSTFIELDS => http_build_query($data)
For clarity, the Wistia API says it returns JSON, but doesn't expect it in the request.
