I use my FormJinn engine... here's a login form as an example:
<?php
function createForm()
{
$formJinn = &$this->getServiceRef( 'formJinn' );
$trans = &$this->getServiceRef( 'translation' );

$fields = array();
$values = array();
$preProcessors = array();
$validators = array();
$postProcessors = array();
$fields['username'] = 'text';
$fields['password'] = 'password';
$fields['redirect'] = 'hidden';
$fields['continue'] = 'submit';
//////////////////////////////////////////////////////////////////////
//

$redirect = trim( (string)$this->getHttpGetVar( 'redirect' ) );
if( $redirect )
{
$values['redirect'] = $redirect;
}
//////////////////////////////////////////////////////////////////////

$widgetAtts = array
(
'username' => array

'continue' => array
(
'label' => $trans->get( 'Login' ),
),
);

$validators = array
(
'username' => array
(
array
(
'type' => 'mandatory',
'errorMessage' =>
$trans->expand( '[!Required][!:] [!email
address]' ),
),
),
'password' => array
(
array
(
'type' => 'mandatory',
'errorMessage' =>
$trans->expand( '[!Required][!:] [!password]' ),
),
),
);
//////////////////////////////////////////////////////////////////////

$processHandler = array

array

'method' => 'processLoginSubmission',
),
);
//////////////////////////////////////////////////////////////////////

$criteria = array
(
'formInfo' => array
(
'name' => $this->formName,
'actionUrl' => $this->actionUrl,
'finalize' => $processHandler,
'aggregateFields' => 'redirect',
),
'fieldInfo' => array
(
'fields' => $fields,
'values' => $values,
'clearValues' => true,
'preProcessors' => $preProcessors,
'validators' => $validators,
'postProcessors' => $postProcessors,
'widgetAtts' => $widgetAtts,
'widgetElements' => $widgetElements,
),
);
$this->slices = $formJinn->generateFormSlices( $criteria );
if( !$formJinn->getFormData( $this->formName, 'valid' ) )
{
$this->hasErrors = true;
}
}
?>
Basically all my forms follow the same form creation pattern with just
the fields and field related settings changing. Makes it very easy and
the form generator creates appropriate CSS classes and field IDs for
easy styling and scripting respectively. I'm not limited to standard
HTML field types either. I can create custom form field types such as
date, time, datetime, rich text (a la fckeditor), double pane selection,
image upload that remembers if an image has been uploaded between
submissions and shows preview, file upload, etc. Also, all the defaults
for widget creation can be overriden. Some clients like DHTML date
widgets instead of the plain vanilla drop down lists of days and
months... in which case I override the date widget that's built into
InterJinn and link it up to a 3rd party DHTML calendar widget. In my
actuall template file I'll have something like follows:
<jinn:module name="loginForm" render="false">
<jinn:component
type="view" name="view"
source="SecuritiesExpertPanel/modules/auth/loginForm.php"/>
</jinn:module>
{comment: ------------------------------------------------------------
//
// Login form.
//
//--------------------------------------------------------------------}
<jinn:render name="loginForm" selector="formOpen"/>
<div class="formLayout">
<jinn:if test="{jinn:value
xpath=module://loginForm/view/hasErrors}">
<div class="formLayout-errors">
<p>
<project:trans phrase="Your submission had the following
errors"/><project:trans phrase=":"/>
</p>
<jinn:render name="loginForm" selector="formError"/>
<jinn:render name="loginForm" selector="username_error"/>
<jinn:render name="loginForm" selector="password_error"/>
</div>
</jinn:if>
<div class="formLayout-row">
<div class="formLayout-label">
<jinn:render name="loginForm" selector="username_textOpen"/>
<project:trans phrase="Email"/><project:trans phrase=":"/>
<project:mandatory/>
<jinn:render name="loginForm"
selector="username_textClose"/>
</div>
<div class="formLayout-input">
<jinn:render name="loginForm" selector="username_field"/>
</div>
</div>
<div class="formLayout-row">
<div class="formLayout-label">
<jinn:render name="loginForm" selector="password_textOpen"/>
<project:trans phrase="Password"/><project:trans
phrase=":"/> <project:mandatory/>
<jinn:render name="loginForm"
selector="password_textClose"/>
</div>
<div class="formLayout-input">
<jinn:render name="loginForm" selector="password_field"/>
</div>
</div>
<div class="formLayout-row">
<div class="formLayout-label">
</div>
<div class="formLayout-input">
<jinn:render name="loginForm" selector="continue_field"/>
</div>
</div>
</div>
<jinn:render name="loginForm" selector="formClose"/>
Cheers,
Rob.
