14       Documentation on templates to use with HTML::FormHandler
15

Using templates

17       There is a FormHandler Template Toolkit rendering role at
18       HTML::FormHandler::Render::WithTT, with a testcase in
19       t/render_withtt.t.  Normally, however, it probably won't make much
20       sense to use both a TT parser in FormHandler, and a separate one for
21       the "complete" templates, so the TT renderer is mainly useful for
22       tests, or as an example of how to do TT rendering with HFH. You should
23       create a template to render your form and then pass the template name
24       and a template variable containing your form object to your templating
25       or view engine, in whatever way you normally do that. If you want to
26       use the 'process_attrs' function, you need to set that in your template
27       variables too.
28
29       A common way of using FormHandler with templates is to use the template
30       for layout, specifying the divs and spans and wrappers, and then use
31       the form object to render just the input fields.
32
33       In your form:
34
35           has '+widget_wrapper' => ( default => 'None' );
36
37       In your Catalyst controller:
38
39           $c->stash( form => $form, template => 'form.tt' );
40
41       ..or do the equivalent for your web framework/view.
42
43       In a form template (form.tt in the previous controller example):
44
45           <form id="myform" action="/myaction" method="post">
46               <div class="span9">
47                   <span class="label">My Foo</span>
48                   [% form.field('foo').render %]
49               </div>
50               <div class="span7">[% form.field('bar').render %]</div>
51               [% form.field('save').render %]
52           </form>
53
54       However, you can also render entirely with templates.  There are lots
55       of different ways to set up templates. There are sample templates
56       installed in FormHandler's 'share' directory. These templates are now
57       organized more-or-less similarly to the widget roles, with 'field',
58       'wrapper', and 'form' directories, but many other organizations are
59       possible.
60
61       There is also a template which combines the template rendering code
62       into one file, 'share/templates/form/form_in_one.tt'. You can copy this
63       template into your own TT directories, perhaps as form.tt, and then
64       specify it as the template for your Catalyst actions. You can customize
65       it by adding additional widget and widget_wrapper blocks, and then
66       setting those in your field definitions.
67
68       Note that widget names usually are camelcased, like the Moose roles
69       that implement them in the Widget directory. You may want to use the
70       non-camelcased widget/wrapper names in your TT templates, using the
71       "$field->uwidget" (un-camelcased widget name) and "$field->twidget"
72       (un-camelcased widget name + '.tt') convenience methods.
73       ('MySpecialWidget' is the equivalent of 'my_special_widget')
74
75          has_field 'my_field' => ( widget => 'MySpecialWidget' );
76          has_field 'another_field' => ( widget => 'YetAnotherWidget' );
77
78       And include them in a generic template:
79
80          [% PROCESS widget/form_start.tt %]
81
82          [% FOREACH f IN form.sorted_fields %]
83             [% PROCESS widget/${f.twidget} %]
84          [% END %]
85
86          [% PROCESS widget/form_end.tt %]
87

Field attributes

89       If you want to use the 'process_attrs' function to pull in HTML
90       attributes for the input elements, wrappers, and labels, you would need
91       to pass that function into your TT setup. See
92       HTML::FormHandler::Render::WithTT for an example:
93
94           use HTML::FormHandler::Render::Util ('process_attrs');
95           $c->stash( process_attrs => &process_attrs ); # or add to TT vars in your view
96
97           <label [% process_attrs(f.label_attributes) %]for="[% f.html_name %]">
98           [% f.label %]: </label>
99           <input type="[% f.input_type %]" name="[% f.html_name %]" id="[% f.id %]"
100           [% process_attrs(f.attributes) %] value="[% f.fif %]">
101

Sample templates

103       The following is copied from the provided
104       share/templates/form/form_in_one.tt file, as an example. Note that some
105       fields, like form actions of 'submit' & 'reset', don't use the 'fif'
106       value, but just the plain field value.
