You should use Form API to create and manage file uploads and their management. You can do something like this instead:

$form['file'] = array(
    '#title' => t('File'),
    '#type' => 'managed_file',
    '#description' => t('File formats: %format. Maximum: %max_size. Resolution %resolution', array('%format' => 'Jpg, Jpeg, Png, Gif', '%max_size' => '800 Kb', '%resolution' => '80x100')),
    '#upload_location' => 'public://',

and submit function:

$node = node_load(32);
$file_d = $form_state['values']['file'];
$file = file_load($file_d);
$file->status = FILE_STATUS_PERMANENT;
file_usage_add($file, 'node', 'TYPE', $file->fid);
$file_info = image_get_info($file->uri);

$file_arr = array(
  'fid' => $file->fid,
  'alt' => '',
  'title' => '',
  'width' => $file_info['width'],
  'height' => $file_info['height'],
  'uid' => $file->uid,
  'filename' => $file->filename,
  'uri' => $file->uri,
  'filemime' => $file->filemime,
  'filesize' => $file->filesize,
  'status' => 1,
  'timestamp' => $file->timestamp,
  'rdf_mapping' => array(),

$node->field_ftest[LANGUAGE_NONE][0] = $file_arr;
  • yes thats the clean way but i'm restricted to add custom module

  • @Paniyar you don't need to create a custom module.. You can just create a form even in template.php and embed it anywhere with drupal_get_form() function. Form generation callback is just a PHP function..

I guess you should use this way:

$file = file_save_data($image, 'public://' . $filename, FILE_EXISTS_RENAME);
