NAME

Catalyst::Plugin::FillInForm - FillInForm for Catalyst

SYNOPSIS

    use Catalyst 'FillInForm'; 
    # that's it, if Catalyst::Plugin::FormValidator is being used

    # OR, manually:

    # in Controller/Root.pm; assume $c->stash->data is seeded elsewhere
    sub end : Private {
      my ( $self, $c ) = @_;
      $c->forward('MyApp::View::TT') unless $c->res->output;
      $c->fillform( $c->stash->data );
      # ....

DESCRIPTION

Fill forms automatically, based on data from a previous HTML form. Typically (but not necessarily) used in conjunction with Catalyst::Plugin::FormValidator. This module automatically inserts data from a previous HTML form into HTML input fields, textarea fields, radio buttons, checkboxes, and select tags. It is an instance of HTML::FillInForm, which itself is a subclass of HTML::Parser, which it uses to parse the HTML and insert the values into the proper form tags.

The usual application is after a user submits an HTML form without filling out a required field, or with errors in fields having specified constraints. FillInForm is used to redisplay the HTML form with all the form elements containing the submitted info. FillInForm can also be used to fill forms with data from any source, e.g. directly from your database.

EXTENDED METHODS

finalize

Will automatically fill in forms, based on the parameters in $c->req->parameters, if the last form has missing or invalid fields, and if Catalyst::Plugin::FormValidator is being used. finalize is called automatically by the Catalyst Engine; the end user will not have to call it directly. (In fact, it should never be called directly by the end user.)

METHODS

fillform

Fill a form, based on request parameters (the default) or any other specified data hash. You would call this manually if you're getting your data from some source other than the parameters (e.g. if you're seeding an edit form with the results of a database query), or if you're using some other validation system than Catalyst::Plugin::FormValidator.

    $c->fillform; # defaults to $c->req->parameters

    # OR

    $c->fillform( \%data_hash );

fillform must be called after an HTML template has been rendered. A typical way of using it is to place it immediately after your forward call to your view class, which might be in a built-in end action in your application class.

You can also hand in a hashref of additional params for HTML::FillInForm->fill() if you like. Explicitly providing a \%data_hash is mandatory for this use case.

    $c->fillform( $c->req->parameters, {
       ignore_fields => [ 'pagesrc', 'pagedst' ],
       fill_password => 0,
    } );

NOTES

This class does not play well with Catalyst's ActionClass('RenderView') so you may want to check your end method (in Controller/Root.pm or perhaps MyApp.pm). If it looks like this:

     sub end : ActionClass('RenderView') {}

Then you'll need to change it to something like this:

     sub end : Private {
        my ($self, $c) = @_;
        $c->forward('render');
        $c->fillform($c->req->params) unless $c->res->output;
     }

     sub render : ActionClass('RenderView') { }
