I got this error after migrating from Drupal 6 to Drupal 8.1.3.

Drupal\Component\Plugin\Exception\PluginNotFoundException: The "php" plugin does not exist. in Drupal\Core\Plugin\DefaultPluginManager->doGetDefinition() (line 52 of core\lib\Drupal\Component\Plugin\Discovery\DiscoveryTrait.php).

How can I fix this error?

  • This most likely shows up when viewing content that is configured to display a text format that had php plugin enabled previously. I needed to re-save all of my text formats after migrating from Drupal 6 to Drupal 8.

It's a guess, but the php module was removed from core in D8 and is now supplied by a contrib module: PHP

You will need to install it additionally.

Edit 1:

If you don't intend to use the module in the future, enable it only temporarily, find alternatives for the fields/text formates currently using it (if needed, the filter may be available but not actually used for php) then uninstall it again once you are done.

  • Not that I am aware of. Personally I would enable it, find all places were the php filter was enabled/used find an alternative that works for your purpose and uninstall php module again.

  • While I don't know how to remove the php options from fields in the db, you can try to enable the php module manually in the db: drupal.org/node/157632

Do these actions in your database :

  1. Locate php_code in 'node_revision_body' table at 'body_format' column, and change it from 'php_code' to 'filtered_html'.

  2. There is also 'filter.format.php_code' in my config table, i delete that.

  3. drush cr.

  4. Enable 'php' module from drush using the command 'drush pm-enable php'.
