[vcl4php-developers] checkbox fix

[Jonathan B. <co...@jo...>]

There is a bug in the Checkbox control that shows when one uses a Checkbox 
with no caption. The checkbox automatically sets its Checked property to 
true when the form is submitted.

Basically the Checkbox compares its Caption (which is an empty string) 
against the POST array, without checking that it even exists in the POST 
array. The POST array returns an empty string for non-existant items, so the 
Checkbox incorrect determines that it has been checked.

I've attached a patch that fixes this issue.
