t has many ways to do that. Here I have mentioned the simplest way for it.

```
 // Assign your checkbox value into $isChecked variable.
$isChecked = $this->request->date['your_check_box'];

// If checked
if($isChecked){
    // then it will create new entity with validation
    $data = $this->YOUR_MODEL_NAME->newEntity($this->request->date, ['validate' => true]);
}
else{
    // otherwise it will create new entity without validation
    $data = $this->YOUR_MODEL_NAME->newEntity($this->request->date, ['validate' => false]);
}
```

Conditional Validation in Cake is in the book: [https://book.cakephp.org/3.0/en/core-libraries/validation.html#conditional-validation](https://book.cakephp.org/3.0/en/core-libraries/validation.html#conditional-validation)

Also my tutorial with an example of its use: [http://www.naidim.org/cakephp-3-tutorial-21-conditional-validation](http://www.naidim.org/cakephp-3-tutorial-21-conditional-validation)
