CGI::FormBuilder::Messages - Localized message support for FormBuilder

use CGI::FormBuilder::Messages;
my $mesg = CGI::FormBuilder::Messages->new(
                $file || \%hash || ':locale'
print $mesg->js_invalid_text;

This module handles localization for FormBuilder. It is invoked by specifying the "messages" option to FormBuilder's new() method. Currently included with FormBuilder are several different locales:

English (default)    en_US
Danish               da_DK
German/Deutsch       de_DE
Spanish/Espanol      es_ES
Japanese             ja_JP
Norwegian/Norvegian  no_NO
Turkish              tr_TR
Russian              ru_RU

To enable automatic localization that will detect the client's locale and use one of these included locales, simply turn on "auto" messages:

my $form = CGI::FormBuilder->new(messages => 'auto');

Or, to use a specific locale, specify it as ":locale"

# Force Danish messages
my $form = CGI::FormBuilder->new(messages => ':da_DK');

In addition to these included locales, you can completely customize your own messages. Each message that FormBuilder outputs is given a unique key. You can selectively override FormBuilder messages by specifying a different message string for a given message key.

To do so, first create a file and give it a unique name. In this example we will use a shortened locale as the suffix:

# messages.en
# FormBuilder messages for "en" locale
js_invalid_start      %s error(s) were found in your form:\n
js_invalid_end        Fix these fields and try again!
js_invalid_select     - You must choose an option for the "%s" field\n

Then, specify this file to new().

my $form = CGI::FormBuilder->new(messages => 'messages.en');

Alternatively, you could specify this directly as a hashref:

my $form = CGI::FormBuilder->new(
      messages => {
          js_invalid_start  => '%s error(s) were found in your form:\n',
          js_invalid_end    => 'Fix these fields and try again!',
          js_invalid_select => '- Choose an option from the "%s" list\n',

Although in practice this is rarely useful, unless you just want to tweak one or two things.

This system is easy, and there are many many messages that can be customized. Here is a list of messages, along with their default values:

form_invalid_input          Invalid entry
form_invalid_checkbox       Check one or more options
form_invalid_file           Invalid filename
form_invalid_password       Invalid entry
form_invalid_radio          Choose an option
form_invalid_select         Select an option from this list
form_invalid_textarea       Please fill this in
form_invalid_default        Invalid entry
form_invalid_text           %s error(s) were encountered with your submission.
                            Please correct the fields %shighlighted%s below.
form_required_text          Fields that are %shighlighted%s are required.
form_confirm_text           Success! Your submission has been received %s.
form_select_default         -select-
form_grow_default           Additional %s
form_other_default          Other:
form_reset_default          Reset
form_submit_default         Submit
js_noscript                 Please enable JavaScript or use a newer browser.
js_invalid_start            %s error(s) were encountered with your submission:
js_invalid_end              Please correct these fields and try again.
js_invalid_checkbox         - Check one or more of the "%s" options
js_invalid_default          - Invalid entry for the "%s" field
js_invalid_file             - Invalid filename for the "%s" field
js_invalid_input            - Invalid entry for the "%s" field
js_invalid_multiple         - Select one or more options from the "%s" list
js_invalid_password         - Invalid entry for the "%s" field
js_invalid_radio            - Choose one of the "%s" options
js_invalid_select           - Select an option from the "%s" list
js_invalid_textarea         - Please fill in the "%s" field
mail_confirm_subject        %s Submission Confirmation
mail_confirm_text           Your submission has been received %s, and will be processed shortly.
mail_results_subject        %s Submission Results

The "js_" tags are used in JavaScript alerts, whereas the "form_" tags are used in HTML and templates managed by FormBuilder.

In some of the messages, you will notice a %s "printf" format. This is because these messages will include certain details for you. For example, the "js_invalid_start" tag will print the number of errors if you include the %s format tag. Of course, this is optional, and you can leave it out.

The best way to get an idea of how these work is to experiment a little. It should become obvious really quickly.
