Question

I have just started using cakePHP 2.1. After submiting a form. If there is a validation error how to check the params whether there is an error ?

Before we used to do something like

$this->data['params'];

Answer 1

For example if you are saving the data in Form submit and you have validations defined on that Model, the data will be saved only when the call to Model->save() returns true. In that case most probably you have validations error. The way you can specifically check is to check Model’s validationErrors proprty.

In your controller

    if(!$this->Model->save($data)) {
         if(!empty($this->Model->validationErrors)) {
             //save failed due to validation errors
             debug($this->Model->validationErrors);
         }
    }
