When I'm editing a picture (ImageController) I'm get the picture added in my database. So I'm having two pictures so the one that was already on the db and the new one. I'm using the https://github.com/josegonzalez/cakephp-upload plugin.

edit.ctp

<div class="images form">
<?php echo $this->Form->create('Image', array('type' => 'file')); ?>
	<fieldset>
		<legend><?php echo __('Edit Image'); ?></legend>
		<div class="alert alert-dismissable alert-success">
<button class="close" data-dismiss="alert" type="button">×</button>
<strong>Orientation and Filename</strong> must have values on "Edit" and on "Add"
</div>	
	<?php
		echo $this->Form->input('file_name', array('type' => 'file'));
		echo $this->Form->input('field', array(
    'options' => array('landscape', 'portrait')
));
		echo $this->Form->input('title');
		echo $this->Form->input('caption');
	?>
	</fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
</div>
<div class="actions">
	<h3><?php echo __('Actions'); ?></h3>
	<ul>

		<li><?php echo $this->Form->postLink(__('Delete'), array('action' => 'delete', $this->Form->value('Image.id')), null, __('Are you sure you want to delete # %s?', $this->Form->value('Image.id'))); ?></li>
		<li><?php echo $this->Html->link(__('List Images'), array('action' => 'index')); ?></li>
	</ul>
</div>

ImagesController.php

<?php

/**
 * edit method
 *
 * @throws NotFoundException
 * @param string $id
 * @return void
 */
	public function edit($id = null) {
		if (!$this->Image->exists($id)) {
			throw new NotFoundException(__('Invalid image'));
		}
		if ($this->request->is(array('post', 'put'))) {
			if ($this->Image->save($this->request->data)) {
				$this->Session->setFlash(__('The image has been saved.'));
				return $this->redirect(array('action' => 'index'));
			} else {
				$this->Session->setFlash(__('The image could not be saved. Please, try again.'));
			}
		} else {
			$options = array('conditions' => array('Image.' . $this->Image->primaryKey => $id));
			$this->request->data = $this->Image->find('first', $options);
		}
	}


?>

savant: echo $this->Form->input('id'); //on edit.ctp

Form->input('id'); echo $this->Form->input('file_name', array('type' => 'file')); echo $this->Form->input('field', array( 'options' => array('landscape', 'portrait') )); echo $this->Form->input('title'); echo $this->Form->input('caption'); ?>
