I know that :)
What I needed is a simple way to output and process a number of very
similar fields. Let's say, you want to ban 10 users from a forum at
once. After you've found these users, you could output this:
<input type="checkbox" name="User[10][IsBanned]" value="banned" />
<input type="checkbox" name="User[20][IsBanned]" value="banned" />
<input type="checkbox" name="User[30][IsBanned]" value="banned" />
etc.
After the form is submitted you could do this in PHP:
while(list($key, $value) = each($_POST['User']))
{
/* $key now holds 10, 20, 30 ..., $val holds the value of the checkbox */
}
Additionally each field is accessible through $_POST['User']['10']['isBanned'].
This is possible because PHP treats incoming fields with names like
User[10][isBanned] as associative arrays.
Unfortunately, in CF I cannot do access a field by writing
form.User['20']['IsBanned']. So I ended up writing my own function
which attempts to emulate this behaviour. I also wondered whether
there already was a function somewhere emulating this behaviour. Alas.
:) :(
