How to Upload Inline-Images using Graph API Batch Request? - php

Question

I'm trying to upload images using Graph API Batch Request, but i'm unable to upload using inline image, can anyone help me please?
Batch Request Docs: https://developers.facebook.com/docs/reference/api/batch/
Photo batch uploads: http://developers.facebook.com/blog/post/493/
Photo batch uploads blog post code works fine, but i want to upload images from my server and not from my pc, Ex: /public_html/image/pic.jpg and i'm not sure how i can do it.
EDIT: I'm using PHP SDK 3.0.1
Here's my code:

CODE WAS CHANGED AND THE PROBLEM IS FIXED ALREADY, SEE THE ANSWER BELOW

This is from their docs:
Uploading binary data
Binary data can be specified as part of the multipart/mime portion of
the batch API request. The batch Graph API allows uploading multiple
binary items as part of a batch call. In order to do this, you need to
add all the binary items as multipart/mime attachments to your
request, and need each operation to reference its binary items using
the "attached_files" property in the operation. The "attached_files"
property can take a comma separated list of attachment names in its
value.
The following example shows how to upload 2 photos in a single batch
call:
curl
–F ‘access_token=…’ \
-F ‘batch=[{“method”:”POST”, \
“relative_url”:”me/photos”, \
“body”:”message=My cat photo” \
"attached_files":"file1" \
},
{“method”:”POST”, \
“relative_url”:”me/photos”, \
“body”:”message=My dog photo” \
"attached_files":"file2" \
},
]’
-F ‘file1=#cat.gif’ \
-F 'file2=#dog.jpg' \

Answer 1

The first issue I see is that the Batch should not be part of the URL, but rather part of the params ...
See the crude batch example below:
$batch = array();
$req = array(
'method' => 'GET',
'relative_url' => '/me'
);
$batch[] = json_encode($req);
$req = array(
'method' => 'GET',
'relative_url' => '/me/albums'
);
$batch[] = json_encode($req);
$params = array(
'batch' => '[' . implode(',',$batch) . ']'
);
try {
$info = $facebook->api('/','POST',$params);
} catch(FacebookApiException $e) {
error_log($e);
$info = null;
}
if(!empty($info)){
if($info[0]['code'] == '200'){
$user_profile = json_decode($info[0]['body']);
}
if($info[1]['code'] == '200'){
$user_albums = json_decode($info[1]['body']);
}
echo "<pre>User Profile:\n";
print_r($user_profile);
echo "\nAlbums\n";
print_r($user_albums);
echo "<pre>";
}
Notice specifically how the $facebook->api call is formatted ...
EDIT:
Here is a working batch picture upload:
$files = array(
'/data/Pictures/pic1.jpg',
'/data/Pictures/pic2.jpg',
'/data/Pictures/pic3.jpg'
);
//Must set upload support to true
$facebook->setFileUploadSupport(true);
$batch = array();
$params = array();
$count = 1;
foreach($files as $file){
$req = array(
'method' => 'POST',
'relative_url' => '/me/photos',
'attached_files' => 'file' . $count
);
//add this request to the batch ...
$batch[] = json_encode($req);
//set the filepath for the file to be uploaded
$params['file'.$count] = '#' . realpath($file);
$count++;
}
$params['batch'] = '[' . implode(',',$batch) . ']';
try{
$upload = $facebook->api('/','post',$params);
} catch(FacebookApiException $e) {
error_log($e);
$upload = null;
}
//View the results ...
if(!is_null($upload)){
echo "<pre>" . print_r($upload,1) . "<pre>";
echo "<hr />";
}
Just tested and it works like a charm ...

Well, I'm not too sure and I cannot check at the moment, but
http://au.php.net/manual/en/function.curl-setopt.php
Look it up at CURLOPT_POSTFIELDS, it says:
The full data to post in a HTTP "POST" operation. To post a file,
prepend a filename with # and use the full path. The filetype can be
explicitly specified by following the filename with the type in the
format ';type=mimetype'. This parameter can either be passed as a
urlencoded string like 'para1=val1&para2=val2&...' or as an array with
the field name as key and field data as value. If value is an array,
the Content-Type header will be set to multipart/form-data. As of PHP
5.2.0, files thats passed to this option with the # prefix must be in array form to work.
Here is another CURL example:
CURL PHP send image
So what you need to do is
$queries = array(
array("method" => "POST", "relative_url" => "me/photos","body" => "message=cool","attached_files" => 'file1')
);
and
$batch = $facebook->api("/?batch=".json_encode($queries)."&file1=#pic.jpg", 'POST');

Answer 3

// // File you want to upload/post
$post_data['file1'] = "#D:/home/2.jpg";
$post_data['file2'] = "#D:/home/1.jpg";
// Initialize cURL
$ch = curl_init();
// Set URL on which you want to post the Form and/or data
curl_setopt($ch, CURLOPT_URL, $post_url);
// Data+Files to be posted
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
// Pass TRUE or 1 if you want to wait for and catch the response against the request made
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
// For Debug mode; shows up any error encountered during the operation
curl_setopt($ch, CURLOPT_VERBOSE, 1);
// Execute the request
$response = curl_exec($ch);
// echo curl_errno($ch);
// echo curl_error($ch);
// Just for debug: to see response
echo $response;
This will work for sure its working for me
