How to post an image to Twitter with PHP? - php

Question

I'm trying to post a message with an image to Twitter through PHP and cURL. It's working for the message but I don't know how to add the image to it.
From the documentation:
Unlike POST statuses/update, this method
expects raw multipart data. Your POST request's Content-Type should be
set to multipart/form-data with the media[] parameter
This is the PHP:
<?php
class Tweet {
public $url = 'https://api.twitter.com/1.1/statuses/update_with_media.json';
function the_nonce(){
$nonce = base64_encode(uniqid());
$nonce = preg_replace('~[\W]~','',$nonce);
return $nonce;
}
function get_DST($status){
$url = $this->url;
$consumer_key = "[removed]";
$nonce = $this->the_nonce();
$sig_method = 'HMAC-SHA1';
$timestamp = time();
$version = "1.0";
$token = "[removed]";
$access_secret = "[removed]";
$consumer_secret = "[removed]";
$param_string = 'oauth_consumer_key='.$consumer_key.
'&oauth_nonce='.$nonce.
'&oauth_signature_method='.$sig_method.
'&oauth_timestamp='.$timestamp.
'&oauth_token='.$token.
'&oauth_version='.$version.
'&status='.rawurlencode($status);
$sig_base_string = 'POST&'.rawurlencode($url).'&'.rawurlencode($param_string);
$sig_key = rawurlencode($consumer_secret).'&'.rawurlencode($access_secret);
$tweet_sig = base64_encode(hash_hmac('sha1', $sig_base_string, $sig_key, true));
$DST = 'OAuth oauth_consumer_key="'.rawurlencode($consumer_key).'",'.
'oauth_nonce="'.rawurlencode($nonce).'",'.
'oauth_signature="'.rawurlencode($tweet_sig).'",'.
'oauth_signature_method="HMAC-SHA1",'.
'oauth_timestamp="'.rawurlencode($timestamp).'",'.
'oauth_token="'.rawurlencode($token).'",'.
'oauth_version="1.0"';
return $DST;
}
function set($status){
$url = $this->url;
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: ' . $this->get_DST($status)));
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'status='.rawurlencode($status));
curl_setopt($ch, CURLOPT_URL, $url);
$result = json_decode(curl_exec($ch));
$resultString = print_r($result,true);;
curl_close($ch);
}
$status->set("hello");
?>
How to add the media[] part to it?

Answer 1

not sure if Matt Harris' library would do for you, but the code is rather simple
require_once ('your_app_tokens.php');
require_once ('tmhOAuth.php');
$connection = new tmhOAuth(array(
'consumer_key' => $consumer_key,
'consumer_secret' => $consumer_secret,
'user_token' => $user_token, //stored in session or whatever else
'user_secret' => $User_secret
));
$message ="test";
$image = "image.jpg"; // must be in the same directory
$extension = "jpg";
$post = $connection->request(
'POST',
'https://api.twitter.com/1.1/statuses/update_with_media.json',
array(
'media[]' => "#{$image};type=image/{$extension};filename={$image}",
'status' => $message
),
true,
true
);
$code = $connection->response;
//if the code is 200 it's all fine

i've created a script that allows you to post a tweet with image. I'm using the php fonction that used an url to upload the image to your server. After that, it upload from your server to the twitter one. You got an image ID that you can use to send a tweet with a picture.
Here is my github projet. Everything is inside, easy to used and install.
