To do so, specify the \f(CW\*(C`template\*(C'\fR option as a hashref which includes the \f(CW\*(C`type\*(C'\fR option set to \f(CW\*(C`TT2\*(C'\fR and the \f(CW\*(C`template\*(C'\fR option set to the name of the template you want processed. You can also add \f(CW\*(C`variable\*(C'\fR as an option (among others) to denote the variable name that you want the form data to be referenced by: .PP .Vb 8 \& my $form = CGI::FormBuilder\->new( \& fields => \e@fields, \& template => { \& type => \*(AqTT2\*(Aq, \& template => \*(Aquserinfo.tmpl\*(Aq, \& variable => \*(Aqform\*(Aq, \& } \& ); .Ve .PP The following methods are provided (usually only used internally): .SS "engine" .IX Subsection "engine" Returns a reference to the \f(CW\*(C`Template\*(C'\fR object .SS "prepare" .IX Subsection "prepare" Returns a hash of all the fields ready to be rendered. .SS "render" .IX Subsection "render" Uses the prepared hash and expands the template, returning a string of \s-1HTML.\s0 .SH "TEMPLATES" .IX Header "TEMPLATES" The template might look something like this: .PP .Vb 10 \& \& \& [% form.title %] \& [% form.jshead %] \& \& \& [% form.start %] \& \& [% FOREACH field = form.fields %] \& \& \& \& \& [% END %] \& \& \& \&

\& [% field.required \& ? "$field.label" \& : field.label \& %] \&	\& [% IF field.invalid %] \& Missing or invalid entry, please try again. \& \& [% END %] \& \& [% field.field %] \&
\& [% form.submit %] [% form.reset %] \&

\& [% form.end %] \& \& .Ve .PP By default, the Template Toolkit makes all the form and field information accessible through simple variables. .PP .Vb 8 \& [% jshead %] \- JavaScript to stick in \& [% title %] \- The of the HTML form \& [% start %] \- Opening <form> tag and internal fields \& [% submit %] \- The submit button(s) \& [% reset %] \- The reset button \& [% end %] \- Closing </form> tag \& [% fields %] \- List of fields \& [% field %] \- Hash of fields (for lookup by name) .Ve .PP You can specify the \f(CW\*(C`variable\*(C'\fR option to have all these variables accessible under a certain namespace. For example: .PP .Vb 8 \& my $form = CGI::FormBuilder\->new( \& fields => \e@fields, \& template => { \& type => \*(AqTT2\*(Aq, \& template => \*(Aqform.tmpl\*(Aq, \& variable => \*(Aqform\*(Aq \& }, \& ); .Ve .PP With \f(CW\*(C`variable\*(C'\fR set to \f(CW\*(C`form\*(C'\fR the variables are accessible as: .PP .Vb 3 \& [% form.jshead %] \& [% form.start %] \& etc. .Ve .PP You can access individual fields via the \f(CW\*(C`field\*(C'\fR variable. .PP .Vb 5 \& For a field named...

For example: .PP .Vb 1 \& [% myfield = form.field.email %] \& \& [% myfield.label %] # text label \& [% myfield.field %] # field input tag \& [% myfield.value %] # first value \& [% myfield.values %] # list of all values \& [% myfield.option %] # first value \& [% myfield.options %] # list of all values \& [% myfield.required %] # required flag \& [% myfield.invalid %] # invalid flag .Ve .PP The \f(CW\*(C`fields\*(C'\fR variable contains a list of all the fields in the form. To iterate through all the fields in order, you could do something like this: .PP .Vb 5 \& [% FOREACH field = form.fields %] \& <tr> \& <td>[% field.label %]</td> <td>[% field.field %]</td> \& </tr> \& [% END %] .Ve .PP If you want to customise any of the Template Toolkit options, you can set the \f(CW\*(C`engine\*(C'\fR option to contain a reference to an existing \&\f(CW\*(C`Template\*(C'\fR object or hash reference of options which are passed to the \f(CW\*(C`Template\*(C'\fR constructor. You can also set the \f(CW\*(C`data\*(C'\fR item to define any additional variables you want accesible when the template is processed. .PP .Vb 10 \& my $form = CGI::FormBuilder\->new( \& fields => \e@fields, \& template => { \& type => \*(AqTT2\*(Aq, \& template => \*(Aqform.tmpl\*(Aq, \& variable => \*(Aqform\*(Aq, \& engine => { \& INCLUDE_PATH => \*(Aq/usr/local/tt2/templates\*(Aq, \& }, \& data => { \& version => 1.23, \& author => \*(AqFred Smith\*(Aq, \& }, \& }, \& ); .Ve .PP For further details on using the Template Toolkit, see \f(CW\*(C`Template\*(C'\fR or <http://www.template\-toolkit.org> .SH "SEE ALSO" .IX Header "SEE ALSO" CGI::FormBuilder, CGI::FormBuilder::Template, Template .SH "REVISION" .IX Header "REVISION" \&\f(CW$Id:\fR \s-1TT2\s0.pm 100 2007\-03\-02 18:13:13Z nwiger $ .SH "AUTHOR" .IX Header "AUTHOR" Copyright (c) Nate Wiger <http://nateware.com>.
