Setting checkboxes as checked in model

Gumster · February 2016

I'm using a multi type field inside form_fields() to set bit values as checkboxes.

I've then used on_before_save() to accumulate the bits and sum them into another field.

Now I'm puzzling how to re-set the checked state in the edit view?

My current solution: I've set a javascript array in a js key, with the bit values bit-wised out again, and re-check the checkboxes using that source from controller.js. This is OK but feels like cheating. Is there a way of setting the options in the multi as checked? With a form_builder like set_values()?

To be clear I have this in the model:


public $ages = array(
        1 => '4',
        2 => '5',
        4 => '6',
        8 => '7',
        16 => '8',
        32 => '9',
        64 => '10',
        128 => '11',
        256 => '12',
        512 => '13',
        1024 => '14',
        2048 => '15',
        4096 => '16'
    );
....
$fields['ages'] = array(
    'type' => 'multi', 
    'options' => $this->ages, 
    'mode' => 'checkbox', 
    'row_class' => 'age-range'
);

You can set the "value" parameter to be the array of selected checkbox values (e.g. 1, 2, 4, 8, 16...etc). This may mean that in the form_fields method you need to create that array since by pulling in the values from that field since it won't be in the edit_method by default (which by default is the find_one_array method on the model).

Howdy, Stranger!
