CakePHP: Merge Add and Edit actions into a single HTML form

CakePHP: Merge Add and Edit actions into a single HTML form

This CakePHP example will show you how to merge your Add and Edit forms into a Single Form action.

This may be of benefit if you have a form with complex controller logic that you don’t want to duplicate.

The Controller

We redirect the add and edit actions to use the form action.

controllers/posts_controller.php

<?php
class PostsController extends AppController {
    var $name = 'Posts';
 
    function add() {
        $this->admin_form();
        $this->render('form');
    }
    function edit($id = null) {
        if (!$id && empty($this->data)) {
            $this->_flash(__('Invalid Post.', true),'error');
            $this->redirect(array('action'=>'index'));
        }
        $this->admin_form($id);
        $this->render('form');
    }
     
    function form($id = null) {
        if (!empty($this->data)) {
            $this->Post->create();
            if ($this->Post->save($this->data)) {
                $this->Session->setFlash(__('The Post has been saved.', true));
                $this->redirect(array('action'=>'view',$this->Video->id));
            }
            else {
                $this->Session->setFlash(__('The Post could not be saved. Please, try again.', true));
            }
        }
        if (empty($this->data)) {
            $this->data = $this->Post->read(null, $id);
        }
    }
}
?>

The View

The view can be copied from your current edit template.

views/posts/form.ctp

<?php echo $form->create('Post');?>
    <fieldset>
        <legend><?php __('Post Details');?></legend>
        <?php
        echo $form->input('id');
        echo $form->input('name');
        echo $form->input('body');
        echo $form->input('active',array('type'=>'checkbox'));
        ?>
    </fieldset>
<?php echo $form->end('Submit');?>
