Ah the plot thickens . . . .
So what you want to do is retrieve the data from a form and populate another
form ?
If you want to pass a value into an html form element, you just need to set
its 'value' when you output the form.
From your original example, you have a field called Address1
if we want to send that out to a screen containing a form that the user can
edit we just need to send:
// inside the form construction
echo "<input type='text' name='Address1'
Value='".$_REQUEST('Address1')."'>";
note the string is in two parts with $_REQUEST('Address1') concatenated in
the middle using the dot string operator.
Where things can get a bit tricky is if you have a series of controls -
typically radio buttons or checkboxes with the same name but different
values, here the returned value is another array that has to be examined,
hence my suggestion to examine the incoming data with var_dump() while
debugging.
The above example assumes that you know the name of the field, or you could
simply use $key and $value pairs as in your original posting inside a loop.
