Checkboxes and radio buttons only post back the values for the ones
selected.
If you have:
<form method="post" action="<?php echo $_SERVER['PHP_SELF'];
?>">
<input type="checkbox" name="ids[]" value="1">Option
1<br/>
<input type="checkbox" name="ids[]" value="2">Option
2<br/>
<input type="checkbox" name="ids[]" value="3">Option
3<br/>
</form>
view that, and tick options 1 and 3, only they will be available in $_POST.
This has not changed in any version of php, it has always been this way
- and it will be exactly the same in perl, python, ruby and any other
language.
