Upload a remote photo to an upload

Question

Is it possible to upload a remote picture to Facebook using the Facebook PHP Library??

Instead of using

    $facebook->setFileUploadSupport(true)         


        

Answer 1

Use file_get_contents() to download the file to your server, then file_put_contents() to store it in a temporary, local file for the upload FB transfer process, then unlink() to delete the file afterwards.

<?php

# The URL for the Image to Transfer
$imageURL = 'http://server.com/the_image.jpg';
# Folder for Temporary Files
$tempFilename = $_SERVER['DOCUMENT_ROOT'].'/tempFiles/';

# Unique Filename
$tempFilename .= uniqid().'_'.basename( $imageURL );

# Get the Image
if( $imgContent = @file_get_contents( $imageURL ) ){
  if( @file_put_contents( $tempFilename , $imgContent ) ){

    $facebook->setFileUploadSupport(true);
    $args = array('message' => 'My Caption');
    $args['image'] = '@' . realpath( $tempFilename );

    $data = $facebook->api('/me/photos', 'post', $args);

    # Once done, delete the Temporary File
    unlink( $tempFilename );

  }else{
    # Failed to Save Image
  }
}else{
  # Failed to Get Image
}
