MODIFY ROW BEHAVIOR

It is not only possible to create own classes for models, but also for rows.

<?php
class Row_Product extends Kwf_Model_Db_Row
{
}

<?php
class Productrs extends Kwf_Model_Db
{
    ....
    protected $_rowClass = 'Row_Product';
}

Using that technique you can:

• implement custom logic that gets executed before/after insert/update/delete by overriding eg. _afterInsert
• implement custom __toString method
• implement custom columns by overriding __get
• implement helper methods and business logic as needed by your application

Example for overriding __get:

<?php
class Row_Foo extends Kwf_Model_Db_Row
{
    public function __get($column)
    {
        if ($column == 'foo_formated') {
            if ($this->foo_type == 'green') {
                return trl('It\'s a green color');
            } else if ($this->foo_type == 'blue') {
                return trl('It\'s a blue color');
            } else if ($this->foo_type == 'orange') {
                return trl('It\'s a orange color');
            }
        }
        return parent::__get($column);
    }

    public function __isset($column)
    {
        if ($column == 'foo_formated') {
            return true;
        }
        return parent::__isset($column);
    }
}
