I am working with files in a Drupal module. I added this form:

$form['Background_image'] = [
  '#type'               => 'managed_file',
  '#title'              => t('Image'),
  '#progress_message'   => t('Please wait...'),
  '#progress_indicator' => 'bar',
  '#description'        => t('Click "Browse..." to select an image to upload.'),
  '#required'           => TRUE,
  '#upload_validators'  => ['file_validate_extensions' => ['jpeg jpg png gif']],
  '#upload_location'    => 'public://backgroundimage/',
  '#default_value'      => $this->options['Background_image'],
];

The file is added properly. Once the file is uploaded a remove button appears allowing to remove the file and upload a new one. The problem is that this button is not working. How can I remove an uploaded file?

Once you have uploaded a file you must be having file object so use file_delete(stdClass $file, $force = FALSE) to delete the file.

  • yes but though once the button remove appears it have to work without adding a extra code, like once the form managed_file is created ,the function upload and remove are called automaticly once the user click the button.. – LearningHowToBeAGoodProgrammer Oct 6 '13 at 0:37
