In order to re-populate checkbox following code might be helpful:

set_checkbox('fieldName', 'fieldValue');

Where 'value' is the second parameter of the form_checkbox call. Like this:

form_checkbox('fieldName[]', 'value', set_checkbox('fieldName', 'value'));

Now if you are on edit form then below code might help you

$getVal=$valFromDb; //$valFromDb is actually value of the filed from db as you are on edit page
if($getVal!=0){
{
   echo form_checkbox('fieldName[]', 'value', true);
}
else
{
   echo form_checkbox('fieldName[]', 'value', false);
}
