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 a param() method that works like CGI's param().

$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);

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.

Apache::ASP v2.09 and above

HTML::FillInForm is now integrated with Apache::ASP. To activate, use

PerlSetVar FormFill 1
$Response->{FormFill} = 1

Apache::ASP v2.08 and below

To use HTML::FillInForm, put the following in global.asa

sub fillin {
  my $args = shift;
  my $html = shift;
  my $fif = new HTML::FillInForm;
  my $output = $fif->fill(
                         scalarref => \$html,
                         fdat      => $Apps::Param,
                         );
  $Response->Write($output);
}

Note $Apps::Param is set to either the querystring or form data. Replace with $Request->QueryString or $Request->Form if you wish.

Then put something like this in your apache configuration:

XMLSubsMatch fillin

Finally, surround your forms like this:

<fillin>
  <form>
    <input name="myfield">
  </form>
</fillin>

BUGS

This module has not been tested extensively. Please submit any bug reports to tjmather@anidea.com.

NOTES

Requires Perl 5.005 and HTML::Parser version 3.08.

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.
