Retrieve file URL when upload form is submitted

Question

I have the following code in my form.

function video_subtitles_menu() {
  $items = array();

  $items['video_subtitles_test/upload'] = array(
    'title' => 'Upload Subtitle', //page title
    'description' => 'Uploading subtitle for videos',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('video_upload_subtitles_form'),
    'access callback' => TRUE
  );

  return $items;
}

function video_upload_subtitles_form($form, &$form_state) {
  $form = array('#attributes' => array('enctype' => 'multipart/form-data'));
  $form['video_name'] = array(
    '#title' => t('Name Of the video'),
    '#type' => 'textfield',
  );

  $form['sub_file'] = array(
    '#type' => 'file',
    '#title' => t('Upload video'),
    '#size' => 48,
    '#description' => t('Pick a video file to upload.'),
  );

  $form['submit_button'] = array(
    '#type' => 'submit',
    '#value' => t('Submit'),
  );

  return $form;
}

function video_upload_subtitles_form_validate() {
  if (!file_check_upload('upload')) {
    form_set_error('upload', 'File missing for upload.');
  }
}

function video_upload_subtitles_form_submit($form, &$form_state) {
  $video_name = $form_state['values']['video_name'];
  $file = file_save_upload('sub_file', array());
  print "<pre>";print_r($file);// no response here 
  drupal_set_message(t('The form has been submitted.'));
}

On the submission handler, it only returns the text field. I don't get anything from file upload field, when I use file_save_upload().

This is the response which I get in Firebug. I tried uploading text and Excel files.

What I am trying to do is creating a block where users can upload a file; I then need to get to upload it to a CDN.

found the solution here.I am not sure what is the core issue but below is the solution

This was the comment in the above link where I found solution.

More than likely eveyone who is having a problem here has been developing on their local computer, then are tryng to migrate their system to a remote server. When you do this, you are probably moving your setting for directory paths along as well.

For example the temp path for your images is probably different than the image temp path on your host system.

I recommend this test in Drupal 6.14. goto /admin/settings/file-system

and look at your temporary directory... if its glaring red, then try renaming it to something like: /tmp. if that does not work, try renaming to just tmp ( no forward slash)

Next step to test this will be to upload an image or file. I tested it by uploading a new logo. But remember, that if you do a FULL DB dump from phpmyadmin from your local computer to the new host, you will probably see this problem again.

For Drupal 7 guys I just went to admin/config/media/file-system , so basically find out where the file system is in your config area and I change the '/tmp' to 'tmp'.

After changing it was able to print the file object :)

stdClass Object ( [uid] => 1 [status] => 0 [filename] => 3-26-2014 12-15-54 PM.png [uri] => temporary://3-26-2014 12-15-54 PM.png [filemime] => image/png [filesize] => 30536 [source] => private_file [destination] => temporary://3-26-2014 12-15-54 PM.png [timestamp] => 1395828492 [type] => image [field_replacement] => stdClass Object ( [uid] => 1 [status] => 0 [filename] => 3-26-2014 12-15-54 PM.png [uri] => temporary://3-26-2014 12-15-54 PM.png [filemime] => image/png [filesize] => 30536 [source] => private_file [destination] => temporary://3-26-2014 12-15-54 PM.png [timestamp] => 1395828492 [type] => image ) [fid] => 3102 ) 

Hope it help someone.
