CGI::FormBuilder::Source - Source adapters for FormBuilder
# Define a source adapter
package CGI::FormBuilder::Source::Whatever;
sub new {
my $self = shift;
my $class = ref($self) || $self;
my %opt = @_;
return bless \%opt, $class;
}
sub parse {
my $self = shift;
my $file = shift || $self->{source};
# open the file and parse it, or whatever
my %formopt;
open(F, "<$file") || die "Can't read $file: $!";
while (<F>) {
# ... do stuff to the line ...
$formopt{$fb_option} = $fb_value;
}
# return hash of $form options
return wantarray ? %formopt : \%formopt;
}
This documentation describes the usage of FormBuilder sources,
as well as how to write your own source adapter.
An external source is invoked by using the source option to
the top-level new() method:
my $form = CGI::FormBuilder->new(
source => 'source_file.conf'
);
This example points to a filename that contains a file following
the CGI::FormBuilder::Source::File layout. Like with the template
option, you can also specify source as a reference to a hash,
allowing you to use other source adapters:
my $form = CGI::FormBuilder->new(
fields => \@fields,
source => {
type => 'File',
source => '/path/to/source.conf',
}
);
The type option specifies the name of the source adapter. Currently
accepted types are:
File - CGI::FormBuilder::Source::File
In addition to one of these types, you can also specify a complete package name,
in which case that module will be autoloaded and its new() and parse()
routines used. For example:
my $form = CGI::FormBuilder->new(
fields => \@fields,
source => {
type => 'My::Source::Module',
somefile => '/path/to/source.conf',
}
);
All other options besides type are passed to the constructor for that
source module verbatim, so it's up to you and/or the source module on how
these additional options should be handled.
