set checkbox to checked based on 'if else' statement

[pjf5066]

Hi all fairly new to php and processwire and am having trouble setting a value of one of my fields.  Quick background - I have active projects, pending projects, and completed projects in my system.  If the job is active, then I need to set the field 'is_active' to checked (or I can have a selection and set the selection to Active).  Either way I have an if statement determining if the project is active.  Once I determine it is active, how do I set a checkbox to checked and store in on the databse from the php side?

ProcessWire handles checkboxes internaly with 0 and 1 integers. So you need to do this, to enable the checkbox field and save it. 

$page->of(false); // disable output formatting

$page->checkbox = 1;
$page->save();
