captcha example

Data dump

Below are the dumps of some PHP variables - submit the form to see the changes! 

Contents of the $_POST array:
$_POST = array (
)

Results of a $clonefish->getElementValues() call:
array (
  'captcha' => NULL,
)

There are cases when the above arrays are different. This is not a bug, but a feature: clonefish was written to help with everyday form hassles (like avoiding the missing value of an unchecked checkbox or compiling the whole date string from date selector fields).
