So they are stored as names boxes1...boxesn? You could do a while-loop, checking whether each column exists in POST, adding to the end of a string each time. Then the rest of the fields once that's done.

data::visitor::callback
Data::Visitor::Callback(3pm) User Contributed Perl Documentation Data::Visitor::Callback(3pm)
NAME
Data::Visitor::Callback - A Data::Visitor with callbacks.
VERSION
version 0.28
SYNOPSIS
use Data::Visitor::Callback;
my $v = Data::Visitor::Callback->new(
# you can provide callbacks
# $_ will contain the visited value
value => sub { ... },
array => sub { ... },
# you can also delegate to method names
# this specific example will force traversal on objects, by using the
# 'visit_ref' callback which normally traverse unblessed references
object => "visit_ref",
# you can also use class names as callbacks
# the callback will be invoked on all objects which inherit that class
'Some::Class' => sub {
my ( $v, $obj ) = @_; # $v is the visitor
...
},
);
$v->visit( $some_perl_value );
DESCRIPTION
This is a Data::Visitor subclass that lets you invoke callbacks instead of needing to subclass yourself.
METHODS
new %opts, %callbacks
Construct a new visitor.
The options supported are:
ignore_return_values
When this is true (off by default) the return values from the callbacks are ignored, thus disabling the fmapping behavior as
documented in Data::Visitor.
This is useful when you want to modify $_ directly
tied_as_objects
Whether ot not to visit the "tied" in perlfunc of a tied structure instead of pretending the structure is just a normal one.
See "visit_tied" in Data::Visitor.
CALLBACKS
Use these keys for the corresponding callbacks.
The callback is in the form:
sub {
my ( $visitor, $data ) = @_;
# or you can use $_, it's aliased
return $data; # or modified data
}
Within the callback $_ is aliased to the data, and this is also passed in the parameter list.
Any method can also be used as a callback:
object => "visit_ref", # visit objects anyway
visit
Called for all values
value
Called for non objects, non container (hash, array, glob or scalar ref) values.
ref_value
Called after "value", for references to regexes, globs and code.
plain_value
Called after "value" for non references.
object
Called for blessed objects.
Since "visit_object" in Data::Visitor will not recurse downwards unless you delegate to "visit_ref", you can specify "visit_ref" as the
callback for "object" in order to enter objects.
It is reccomended that you specify the classes (or base classes) you want though, instead of just visiting any object forcefully.
Some::Class
You can use any class name as a callback. This is colled only after the "object" callback.
If the object "isa" the class then the callback will fire.
These callbacks are called from least derived to most derived by comparing the classes' "isa" at construction time.
object_no_class
Called for every object that did not have a class callback.
object_final
The last callback called for objects, useful if you want to post process the output of any class callbacks.
array
Called for array references.
hash
Called for hash references.
glob
Called for glob references.
scalar
Called for scalar references.
tied
Called on the return value of "tied" for all tied containers. Also passes in the variable as the second argument.
seen
Called for a reference value encountered a second time.
Passes in the result mapping as the second argument.
