NAME¶
CGI::FormBuilder::Source - Source adapters for FormBuilder
SYNOPSIS¶
# 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;
}
DESCRIPTION¶
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.
