CGI::FormBuilder::Template::Fast - FormBuilder interface to CGI::FastTemplate
my $form = CGI::FormBuilder->new( fields => \@whatever, template => { type => 'Fast', root => '/path/to/templates', # use external files define => { form => 'form.txt', field => 'field.txt', invalid_field => 'invalid_field.txt', }, # or define inline define_nofile => { form => '<html><head></head><body>$START_FORM <table>$FIELDS</table>$SUBMIT $END_FORM</body></html>', # etc. }, }, );
This engine adapts FormBuilder to use CGI::FastTemplate. Please read these docs carefully, as the usage differs from other template adapters in several important ways.
CGI::FastTemplate
You will need to define three templates: form, field, and invalid_field. You can use define to point to external files (which is the recommended CGI::FastTemplate style), or define_nofile/ define_raw to define them inline. The templates in define_nofile take precedence over define_raw, and both of these take precedence over define.
form
field
invalid_field
define
define_nofile
define_raw
my $form = CGI::FormBuilder->new( # ... template => { type => 'FastTemplate', root => '/path/to/templates', define => { form => 'form.txt', field => 'field.txt', invalid_field => 'invalid_field.txt', }, # or, you can define templates directly define_nofile => { form => '<html><head></head><body>$START_FORM<table>' '$FIELDS</table>$SUBMIT $END_FORM</body></html>', # etc. }, }, # ... );
If you use define with external templates, you will probably also want to define your template root directory with the root parameter.
root
Within each of the field templates, the following variables are available:
$NAME # $field->name $FIELD # $field->tag (HTML input tag) $VALUE # $field->value (first value only!) $LABEL # $field->label $COMMENT # $field->comment $ERROR # $field->error $REQUIRED # $field->required ? 'required' : 'optional'
All the fields are processed in sequence; valid fields use the field template, and invalid fields the invalid_field template. The result from each of these is appended into the $FIELDS variable, which you should use in your form template. In the form template, you also have access to these variables:
$FIELDS
$TITLE # title of the form $START_FORM # opening form tag $SUBMIT # the submit button $RESET # the reset button $END_FORM # closing form tag $JS_HEAD # validation JavaScript
Note that since CGI::FastTemplate doesn't use anything other than simple scalar variables, there are no variables corrosponding to the lists that other engines have (e.g. fields or options lists in TT2 or Text::Template).
