                'label'     => Mage::helper('cms')->__('Three'),
            ),  
            array(
                'value'     => 3,
                'label'     => Mage::helper('cms')->__('FOur'),
            ),                                        
        ),
        'value' => $model->getCounts(),
    ));

When i save, its saved as "Array".Please anyone help me to save the option values to the database..

Answer 1

The problem is, you need to transform your array to a string before saving it to the database.

This can be done in an observer listening to cms_page_load_after/before to transform string to array and cms_page_save_before/after to transform it back. And after the saving it should be transformed back...
