Checkbox default value

[ceroz]

$my_meta->addCheckbox('1_checkbox_field_id',array('name'=> 'My Checkbox 1'));
$my_meta->addCheckbox('2_checkbox_field_id',array('name'=> 'My Checkbox 2'));
$my_meta->addCheckbox('3_checkbox_field_id',array('name'=> 'My Checkbox 3'));
$my_meta->addCheckbox('4_checkbox_field_id',array('name'=> 'My Checkbox 4'));

I would like to set default value for these boxes. How this should be written ?

Tried following ways:
'std'=> 'checked'
'std'=> "checked"
'std'=> checked
'std'=> 'true'
'std'=> "true"
'std'=> true

After I disable or enable checkbox the value won't save.

Edit:
'std'=> false - save function works fine but only when I set it to "false". If i type here "true" it won't save the value.

For example:
$my_meta->addCheckbox('1_checkbox_field_id',array('name'=> 'My Checkbox 1', 'std'=> true));

In the admin panel I can see checked box, seems to be working but when i try to uncheck the box and save the value will rollback to "true" (checked)

Maybe you should try addCheckboxList instead.
