               <?php  endforeach;?>
               </td>
            </tr>

and here is my CONTROLLER code

if ($this->request->is('post')) {
                    $this->Artproject->create();


            $this->request->data['Artproject']['ainum'] = 'AI-' . $this->request->data['Artproject']['ainum'];
            $this->request->data['Artproject']['createdby'] = $this->Auth->user('id');

            if ($this->Artproject->save($this->request->data['Artproject'])) {
                  $artid = $this->Artproject->getLastInsertID();

               foreach ($this->request->data['Artdetail']['products'][$prdid]['subproducts'] as $subproducts):

                  //debug($subproducts);

                 $this->request->data['Artdetaill']['category_id'] = $sportid;
                 $this->request->data['Artdetaill']['product_id'] = $prdid;
                 $this->request->data['Artdetaill']['subproduct_id'] = $subproducts;
                  $this->request->data['Artdetaill']['user_id'] = $this->request->data['Artproject']['user_id'];
                 $this->request->data['Artdetaill']['art_id'] = $artid;

                 if(!empty($subproducts['options'])){

                 foreach ($subproducts['options'] as $options):

                $this->request->data['Artdetaill']['option_id'] = $options;
                 $this->Artdetail->saveAll($this->request->data['Artdetaill']);  
                 endforeach;

                 }else{

                      $this->Artdetail->saveAll($this->request->data['Artdetaill']);  
                 }


                 endforeach; 
           exit;
            }

        }

after submit i get this array

array(
    'Artproject' => array(
        'ainum' => '1024',
        'teamname' => 'Basketball',
        'user_id' => '10',
        'createdby' => ''
    ),
    'Artdetail' => array(
        'products' => array(
            (int) 0 => '1',
            (int) 1 => array(
                'subproducts' => array(
                    (int) 0 => '1',
                    (int) 1 => array(
                        'options' => array(
                            (int) 0 => '1',
                            (int) 1 => '2'
                        )
                    ),
                    (int) 2 => '2',

Answer 1

Why not store data by serializing array? Simply serialize($yourarr); and store with a unique key you want to identify your array

Answer 2

Wow....way too much code.

array(
    'Artproject' => array(
        'ainum' => '1024',
        ...
        'Artdetail' => array(...)
    ),    
)

Put your Artdetail object within your Artproject. Then you only need this code in your controller:

    if ($this->request->is('post')) {
        $this->Artproject->create();
        $this->request->data['Artproject']['ainum'] = 'AI-' . $this->request->data['Artproject']['ainum'];
        $this->request->data['Artproject']['createdby'] = $this->Auth->user('id');
        if ($this->Artproject->saveAssociated($this->request->data['Artproject'], array('deep' => true))) { }

    }

Just make sure your model-associations are correct.
