What method do you use for check boxes? I just want them to have a value of true and false. If it's checked when the form is submitted, it'll say true in the database, if not it will be false.

1 and 0.

That doesn't answer anything...

Use 1 for the true value, and 0 for the false value. You can do a set(0,1) or enum(0,1) field in your DB if you'd like

Code:
$input['my_checkbox'] = FALSE;
if (isset($this->input->post('my_checkbox'))) {
  $input['my_checkbox'] = TRUE;
}

Checkboxes have a value of 'on' if they are checked and they are not passed through at all if unchecked.

Code:
$input['my_checkbox'] = FALSE;
if (isset($this->input->post('my_checkbox'))) {
  $input['my_checkbox'] = TRUE;
}
[/quote]

Or in one line (since $this->input->post will return false if the item is not set)
Code:
$input['my_checkbox'] = $this->input->post('my_checkbox') !== FALSE;

(I'm not sure isset will work.. Will it?)

isset won't work on expressions, only does with variables
Code:
// you can't
isset($this->input->post('my_checkbox')); // PHP error
// You can
isset($fake_var = $this->input->post('my_checkbox')); // always true, it is false or the value submitted
//and the good old...
isset($_POST['my_checkbox']); // returns true if submitted, as expected
// or how you suggested
$this->input->post('my_checkbox') !== FALSE; // returns true if submitted

You can use this code in your view when adding checkboxes:
Code:
<input type="hidden" name="myCheckbox" value="0" />
<?=form_checkbox('myCheckbox', '1', myValue)?>

By using the hidden field, the value will be 'zero' if the box is not checked. For me this is preferred over not getting anything back about the field.

This is incorrect
