NAME
HTML::FillInForm - Populates HTML Forms with CGI data.
DESCRIPTION
This module automatically inserts data from a previous HTML form into the HTML input, textarea and select tags. It is a subclass of HTML::Parser and uses it to parse the HTML and insert the values into the form tags.
One useful application is after a user submits an HTML form without filling out a required field. HTML::FillInForm can be used to redisplay the HTML form with all the form elements containing the submitted info.
SYNOPSIS
This examples fills data into a HTML form stored in $htmlForm
from CGI parameters that are stored in $q
. For example, it will set the value of any "name" textfield to "John Smith".
my $q = new CGI;
$q->param("name","John Smith");
my $fif = new HTML::FillInForm;
my $output = $fif->fill(scalarref => \$html,
fobject => $q);
METHODS
- new
-
Call
new()
to create a new FillInForm object:$fif = new HTML::FillInForm;
- fill
-
To fill in a HTML form contained in a scalar
$html
:$output = $fif->fill(scalarref => \$html, fobject => $q);
Returns filled in HTML form contained in
$html
with data from$q
.$q
is required to have aparam()
method that works like CGI'sparam()
.$output = $fif->fill(scalarref => \$html, fobject => [$q1, $q2]);
Note that you can pass multiple objects as an array reference.
$output = $fif->fill(scalarref => \$html, fdat => \%fdat);
Returns filled in HTML form contained in
$html
with data from%fdat
. To pass multiple values using%fdat
use an array reference.Alternately you can use
$output = $fif->fill(arrayref => \@array_of_lines, fobject => $q);
and
$output = $fif->fill(file => 'form.tmpl', fobject => $q);
Suppose you have multiple forms in a html and among them there is only one form you want to fill in, specify target.
$output = $fif->fill(scalarref => \$html, fobject => $q, target => 'form1');
This will fill in only the form inside
<FORM name="form1"> ... </FORM>
Note that this method fills in password fields by default. To disable, pass
fill_password => 0
To disable the filling of some fields, use the
ignore_fields
option:$output = $fif->fill(scalarref => \$html, fobject => $q, ignore_fields => ['prev','next']);
CALLING FROM OTHER MODULES
Apache::PageKit
To use HTML::FillInForm in Apache::PageKit is easy. It is automatically called for any page that includes a <form> tag. It can be turned on or off by using the fill_in_form
configuration option.
Apache::ASP v2.09 and above
HTML::FillInForm is now integrated with Apache::ASP. To activate, use
PerlSetVar FormFill 1
$Response->{FormFill} = 1
HTML::Mason
Using HTML::FillInForm from HTML::Mason is covered in the FAQ on the masonhq.com website at http://www.masonhq.com/docs/faq/#how_can_i_integrate_html_fillin
VERSION
This documentation describes HTML::FillInForm module version 1.02.
SECURITY
Note that you might want to think about caching issues if you have password fields on your page. There is a discussion of this issue at
http://www.perlmonks.org/index.pl?node_id=70482
In summary, some browsers will cache the output of CGI scripts, and you can control this by setting the Expires header. For example, use -expires
in CGI.pm or set browser_cache
to no in Config.xml file of Apache::PageKit.

BUGS
Please submit any bug reports to tjmather@maxmind.com.
NOTES
Requires Perl 5.005 and HTML::Parser version 3.26.
I wrote this module because I wanted to be able to insert CGI data into HTML forms, but without combining the HTML and Perl code. CGI.pm and Embperl allow you so insert CGI data into forms, but require that you mix HTML with Perl.
