NAME

Mojolicious::Plugin::TagHelpers - Tag helpers plugin

SYNOPSIS


            
              
              # Mojolicious
$self->plugin('TagHelpers');
# Mojolicious::Lite
plugin 'TagHelpers';

DESCRIPTION

Mojolicious::Plugin::TagHelpers is a collection of HTML tag helpers for Mojolicious.

Most form helpers can automatically pick up previous input values and will show them as default. You can also use "param" in Mojolicious::Plugin::DefaultHelpers to set them manually and let necessary attributes always be generated automatically.


            
              
              % param country => 'germany' unless param 'country';
<%= radio_button country => 'germany' %> Germany
<%= radio_button country => 'france'  %> France
<%= radio_button country => 'uk'      %> UK

This is a core plugin, that means it is always enabled and its code a good example for learning how to build new plugins, you're welcome to fork it.
