How to use trim() function in CakePHP 2 form when adding data?

<?php

    echo $this->Form->input('unit');

Answer 1

In your controller, before you save() the data:

$this->data['YourModelName'] = array_map('trim', $this->data['YourModelName']);

You can also do it for each field individually instead, if you wish.
