Drupal 7: How to disable a content type

Drupal 7

While developing a site with Drupal, at times I'd like to disable a content type without removing it. I just want to disable one.

The database table where content types are stored is node_type. And there's a column disabled in it. We can disabled a content type by changing the column value to 1.

There are APIs for that. We can use node_type_load() and node_type_save() to do it.

<?php

// Disable a content type named 'article'.
$name = 'article';

$type_info = node_type_load($name);
$type_info->disabled = 1;
node_type_save($type_info);

We can disable a content type easily but re-enabling them is a little tricky. We cannot use node_type_load() for disabled content types and should use db_select() directly.

Here's a sample module only to disable a content type.

<?php

/**
 * @file
 * A module which disable the default Article content.
 */

/**
 * Implements hook_install().
 */
function default_disabler_install() {
  // Disable the article content type.
  _default_disabler_disable_node_type('article');
}

/**
 * Implements hook_install().
 */
function default_disabler_uninstall() {
  // Re-enable the article content type.
  _default_disabler_enable_node_type('article');
}

/**
 * Disable a content type.
 *
 * @param string $name
 *   Content type name (machine name).
 */
function _default_disabler_disable_node_type($name) {
  $type_info = node_type_load($name);

  if ($type_info) {
    $type_info->disabled = 1;
    node_type_save($type_info);
    watchdog('default_disabler', 'Node type @name is disabled.', [
      '@name' => $name,
    ], WATCHDOG_WARNING);
  }
  else {
    watchdog('default_disabler', 'Node type @name is not found and couldn\'t be disabled.', [
      '@name' => $name,
    ], WATCHDOG_WARNING);
  }
}

/**
 * Re-enable a disabled content type.
 *
 * @param string $name
 *   Content type name (machine name).
 */
function _default_disabler_enable_node_type($name) {

  // Since node_type_load() cannot be used for disabled content types,
  // a low-level function db_select() is used here.

  // Re-enable a content type if it's disabled.
  $query = db_select('node_type', 'nt')
    ->fields('nt', array('disabled'))
    ->condition('type', $name);

  $disabled = $query->execute()->fetchAssoc();

  if (!empty($disabled['disabled'])) {
    $query = db_update('node_type')
      ->fields(array('disabled' => 0))
      ->condition('type', $name);
    $result = $query->execute();
    if ($result) {
      watchdog('default_disabler', 'Node type @name is enabled.', [
        '@name' => $name,
      ], WATCHDOG_WARNING);
    }
  }
  else {
    watchdog('default_disabler', 'Node type @name is not found and couldn\'t be enabled.', [
    '@name' => $name,
    ], WATCHDOG_WARNING);
  }
}
