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 |
||
| 3 | class TrainingSignupForm extends Form |
||
|
|
|||
| 4 | { |
||
| 5 | public function __construct($controller, $name, $title = "Training") |
||
| 48 | |||
| 49 | public function doSave($data, $form) |
||
| 85 | |||
| 86 | /* |
||
| 87 | |||
| 88 | I don't think saveInto can deal with saving many_many relations |
||
| 89 | currently, unless your Post class has a customised method called |
||
| 90 | saveCategories($data) in which you simply add the code like this: |
||
| 91 | |||
| 92 | $this->Categories->add($item, $extraFields), |
||
| 93 | where $item should be the category's ID (you can get it from $data), |
||
| 94 | depending on how your Form is stuctured, your $extraFields should be |
||
| 95 | either from $data, or assigned from backend by you before you call |
||
| 96 | saveInto in doPostForm or before you call $this->Categories->add |
||
| 97 | saveCetegories. |
||
| 98 | |||
| 99 | The name of saving many_many relation (here refer to saveCategories) |
||
| 100 | must bond with your field name, ie, if your field is called: |
||
| 101 | new DropdownField('GoneWithWind',"Category", $catOptions), the save |
||
| 102 | method must name as saveGoneWithWind(). |
||
| 103 | |||
| 104 | if PrimeCategory need to be also submitted from from, your your can |
||
| 105 | get CategoryID and PrimeCategory in an array from $data, try this: |
||
| 106 | new DropdownField('Categories[CetegoryID]',"Category", $catOptions), |
||
| 107 | new CheckboxField('Categories[PrimeCategory]', "Prime Category?"), |
||
| 108 | The $data[Categories] submitted from from is a array. |
||
| 109 | |||
| 110 | In addition, dropdown field is not supposed to simulate many_many |
||
| 111 | relation, CheckboxSetField is aim to submit multiple IDs from a form |
||
| 112 | (maybe you have you special consideration here?). If this is the case, |
||
| 113 | $this->Categories->add need to change to $this->Categories- |
||
| 114 | |||
| 115 | */ |
||
| 116 | } |
||
| 117 |
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.
