[FIXED] CakePHP 3 - How to use Trim() before validation NotEmpty?

Issue

My form validate empty fields, but if the user use "space", the validation handle how one character.. How to use Trim() in Model-Table for it not happen?

Solution

Assuming that you have a title column in Posts table and you want to trim title before validating.

put following code in src\Model\Table\PostsTable.php

public function beforeMarshal(Event $event, ArrayObject $data)
    {
        $data['title'] = trim($data['title']);
    }

and add following two lines at the top of src\Model\Table\PostsTable.php

use Cake\Event\Event;
use ArrayObject;

Thanks
