CGI::FormBuilder::Template::TT2User)Contributed Perl DocumentCGI::FormBuilder::Template::TT2(3pm)
NAME
CGI::FormBuilder::Template::TT2 - FormBuilder interface to Template Toolkit
SYNOPSIS
my $form = CGI::FormBuilder->new(
fields => \@fields,
template => {
type => 'TT2',
template => 'form.tmpl',
variable => 'form',
}
);
DESCRIPTION
This engine adapts FormBuilder to use "Template Toolkit". To do so, specify the
"template" option as a hashref which includes the "type" option set to "TT2" and the
"template" option set to the name of the template you want processed. You can also add
"variable" as an option (among others) to denote the variable name that you want the form
data to be referenced by:
my $form = CGI::FormBuilder->new(
fields => \@fields,
template => {
type => 'TT2',
template => 'userinfo.tmpl',
variable => 'form',
}
);
The following methods are provided (usually only used internally):
engine
Returns a reference to the "Template" object
prepare
Returns a hash of all the fields ready to be rendered.
render
Uses the prepared hash and expands the template, returning a string of HTML.
TEMPLATES
The template might look something like this:
<html>
<head>
<title>[% form.title %]</title>
[% form.jshead %]
</head>
<body>
[% form.start %]
<table>
[% FOREACH field = form.fields %]
<tr valign="top">
<td>
[% field.required
? "<b>$field.label</b>"
: field.label
%]
</td>
<td>
[% IF field.invalid %]
Missing or invalid entry, please try again.
<br/>
[% END %]
[% field.field %]
</td>
</tr>
[% END %]
<tr>
<td colspan="2" align="center">
[% form.submit %] [% form.reset %]
</td>
</tr>
</table>
[% form.end %]
</body>
</html>
By default, the Template Toolkit makes all the form and field information accessible
through simple variables.
[% jshead %] - JavaScript to stick in <head>
[% title %] - The <title> 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)
You can specify the "variable" option to have all these variables accessible under a
certain namespace. For example:
my $form = CGI::FormBuilder->new(
fields => \@fields,
template => {
type => 'TT2',
template => 'form.tmpl',
variable => 'form'
},
);
With "variable" set to "form" the variables are accessible as:
[% form.jshead %]
[% form.start %]
etc.
You can access individual fields via the "field" variable.
For a field named... The field data is in...
-------------------- -----------------------
job [% form.field.job %]
size [% form.field.size %]
email [% form.field.email %]
Each field contains various elements. For example:
[% 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
The "fields" 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:
[% FOREACH field = form.fields %]
<tr>
<td>[% field.label %]</td> <td>[% field.field %]</td>
</tr>
[% END %]
If you want to customise any of the Template Toolkit options, you can set the "engine"
option to contain a reference to an existing "Template" object or hash reference of
options which are passed to the "Template" constructor. You can also set the "data" item
to define any additional variables you want accesible when the template is processed.
my $form = CGI::FormBuilder->new(
fields => \@fields,
template => {
type => 'TT2',
template => 'form.tmpl',
variable => 'form',
engine => {
INCLUDE_PATH => '/usr/local/tt2/templates',
},
data => {
version => 1.23,
author => 'Fred Smith',
},
},
);
