delete markdown file in dropbox,but the post is not deleted about justwriting

[jonathanlurie]

I experienced the same issue, thinking using /sync/dropbox/download would synchronize. I actually only adds files.
To empty the post folder (ftp side) at the beginning of the sync would solve the problem for dropbox-exclusive users but would cause damage for someone who uses Dropbox AND ftp...
Since I plan to use Dropbox only to post on my blog, I will add this flush-the-post-folder-before-syncing command. Could you give me a clue on which php file/function it is more relevant to write it?

unlink,delete a file

Hi,

I added two stuff to the file application/controllers/dropbox.php :

1. The feature to add files from from dropbox only if it matches certain extensions.

2. Removing the blog post when the corresponding markdown file is removed from the dropbox folder

   It concerns only the function download() so the update is pretty quick

  public function download($value='')
  {
    $debug = false;
    if(isset($_GET['challenge'])){
      echo $_GET['challenge'];exit;
    }
    if(isset($_GET['debug'])){
      $debug = true;
    }
    set_time_limit(60*30);
      $this->load->library('dropbox_lib');
    $client = $this->dropbox_lib->getClient();
    if ($client === false) {
        header("Location:  /sync/dropbox");
        exit;
    }
    $cursor = null;
    $cursor_filename =  FCPATH."posts/cursor.txt";
    if(file_exists($cursor_filename)){
      $cursor = file_get_contents($cursor_filename);
    }
    if(empty($cursor)){
      $cursor = null;
    }
    $changes = $client->getDelta($cursor);

    if($debug){
      print_r($changes);
    }


    if(!empty($changes))
    {

      foreach($changes['entries'] as $row){
        $localFilename = "posts".$row[0];
        $filename = FCPATH.$localFilename;

        // extract the extension to filter the dropbox -> ftp transfert
        $ext = pathinfo($filename, PATHINFO_EXTENSION);
        $authorizedExt = array("md", "txt", "markdown");

        if(in_array($ext, $authorizedExt)){

            if($row[1]['is_dir'] ){
              if(!file_exists($filename)){
                mkdir($filename,0777,true);
              }

            }else{
              if(!file_exists(dirname($filename))){
                mkdir(dirname($filename),0777,true);
            }
              if(!empty($row[1])){ // means "a file was added to Dropbox"
                $fd = fopen($filename, "wb");
                $metadata = $client->getFile($row[0], $fd);
                fclose($fd);
                print_r($metadata);

              }else{ // mean "the file was removed from Dropbox"
                     unlink( $localFilename);
                  }
                }

        } // endif authorized ext
      }
      $cursor = $changes['cursor'];
      if($cursor){
        $fd = fopen($cursor_filename, "wb");
        fwrite($fd,$cursor);
        fclose($fd);
      }
    }
  }

(Sorry for the poor indentation)
It would be cooler to place the accepted extension list ($authorizedExt) to settings.php , but I does the job like that...
Cheers.
