I work with a similar thing right now.
The edit view:
<?php echo $form->create('Contentclass');?>
<fieldset>
<legend><?php __('Edit Contentclass');?></legend>
<?php
echo $form->input('id');
echo $form->input('title');
echo $form->input('attribute_identifier');
echo $form->input('is_container');
echo $form->input('contentclassgroup_id');
?>
</fieldset>
<?php if(!empty($this->data['ContentclassAttribute'])): ?>
<fieldset>
<legend><?php __('Attributes');?></legend>
<?php $n = 0; foreach($this->data['ContentclassAttribute'] as
$att): ?>
<fieldset class="attribute">
<legend><?php __('Attribute Type: ' .
$att['attribute_type']);?></
legend>
<?php
echo $form->input("ContentclassAttribute.{$n}.id",
array('value'=>
$att['id']));
echo $form->input("ContentclassAttribute.{$n}.title",
array('value'=>$att['title']));
echo
$form->input("ContentclassAttribute.{$n}.placement",
array('value'=>$att['placement']));
echo
$form->input("ContentclassAttribute.{$n}.is_required",
array('value'=>$att['is_required']));
echo
$form->input("ContentclassAttribute.{$n}.is_searchable",
array('value'=>$att['is_searchable']));
echo
$form->hidden("ContentclassAttribute.{$n}.attribute_type",
array('value'=>$att['attribute_type']));
echo $html->link(__('Remove this attribute', true),
array('action'=>'removeAttribute', $form->value('Contentclass.id'),
$att['id']), null, sprintf(__('Are you sure you want to remove this
attribute with title %s?', true), $att['title']));
$n++;
?>
</fieldset>
<?php endforeach; ?>
</fieldset>
<?php endif; ?>
<?php echo $form->end('Save');?>
<?php echo $form->create(null, array('action' => 'addattribute'));?>
<fieldset class="attribute addattribute">
<legend><?php __('Add attribute');?></legend>
<div><?php echo $form->select("ContentclassAttribute.attribute_type",
$attribute_types, null, null, ""); ?></div>
<?php echo $form->end('Add new attribute');?>
</fieldset>
</div>
And the controller:
function edit($id = null) {
if (!$id && empty($this->data)) {
$this->Session->setFlash(__('Invalid Contentclass',
true));
$this->redirect(array('action'=>'index'));
}
if (!empty($this->data)) {
if ($this->Contentclass->saveAll($this->data)) {
$this->Session->setFlash(__('The Contentclass
has been saved',
true));
} else {
$this->Session->setFlash(__('The Contentclass
could not be saved.
Please, try again.', true));
}
}
if (empty($this->data)) {
$this->data = $this->Contentclass->read(null, $id);
}
$contentclassgroups = $this->Contentclass->Contentclassgroup-
>find('list');
$this->set('attribute_types', $this->Contentclass-
>ContentclassAttribute->getAttributeTypes());
$this->set(compact('contentclassgroups'));
}
Hope this helps!
