Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
| 1 | <?php |
||
| 15 | class CommentsGridFieldBulkAction_Handlers extends CommentsGridFieldBulkAction |
||
| 16 | { |
||
| 17 | |||
| 18 | private static $allowed_actions = array( |
||
| 19 | 'spam', |
||
| 20 | 'approve', |
||
| 21 | ); |
||
| 22 | |||
| 23 | private static $url_handlers = array( |
||
| 24 | 'spam' => 'spam', |
||
| 25 | 'approve' => 'approve', |
||
| 26 | ); |
||
| 27 | |||
| 28 | |||
| 29 | View Code Duplication | public function spam(SS_HTTPRequest $request) |
|
| 47 | |||
| 48 | |||
| 49 | View Code Duplication | public function approve(SS_HTTPRequest $request) |
|
| 67 | } |
||
| 68 |
You can fix this by adding a namespace to your class:
When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.
