This function is great for when you have a multi-page form such as an application. This function forwards fields on one page to hidden fields on the next page, and so on. Very
simple to call. The beauty of it is, it also will handle arrays with multiple dimensions. If you have a field with the same name on the next form, it's a good rule to call
field_forwarder() at the BEGINNING of your form so that when that form is passed, the field (with the same name) will overwrite the previous form. It's also good to put
field_forwarder() at the top so the final page will have all the fields in the order of the application. This is a recursive function, i.e. it re-calls itself when it encounters
form elements that are arrays such as: Finally, if you wish to print out PHP code of the array instead of hidden fields, add this line right before you call field_forwarder():
$FFoutputType = 'print'; and it will print out, in text form, the values of the fields as php variables -- this is great for storing php code in a database.
