Hi Reader's,
Welcome to FindNerd,today we are going to discuss  beforeSave() method in CakePHP.

Basically beforeSave() methods is an important feature of CakePHP and this is a pre-save logic. It is also called callback methods in CakePHP. In this function, we can put any pre-save logic. This function returns true if you want the save operation to continue otherwise it always return false.

let see how it is call

beforeSave(array $options = array())

You can see in below example that how we changed date format by beforeSave method, It means we can see the date in our database like YYYY-MM-DD format but in our application it will be show as DD-MM-YYYY format.

Code will like below:

<?php 
  public function beforeSave($options = array()){
    if (!empty($this->data['User']['joindate'])){
           $this->data['User']['joindate'] = $this->dateFormatBeforeSave($this->data['User']['joindate']);
    }
       return true;
  }

  public function dateFormatBeforeSave($dateString){
         return date('Y-m-d', strtotime($dateString));
    }

?>

I hope this blog will help to you for using beforeSave() method in your CakePHP web application.
