Protect more than one directory

Maybe allow user to enter directories separated by a comma, or multiple text input fields?

This module is what I have been looking for! Thanks!

function contentprotector_admin_form() {
  $form = array();
  
  $form['contentprotector_directory'] = array(
    '#type'          => 'textfield',
    '#title'         => t('Directory to protect'),
    '#description'   => t('The path of the directory to protect, relative to the root of your Drupal installation.'),
    '#default_value' => variable_get('contentprotector_directory', ''),
  );
  
  $form['contentprotector_submit'] = array(
    '#type'          => 'submit',
    '#value'         => t('Save'),
  );

  return $form;
