i'm trying format input without success. need save mp3 table duration of each audio file. that, have input allows me choose hours:minutes:seconds. field duration in table time, don't need datetime guess.

so here i've done doesn't work:

<?php echo $this->form->input('duration', array('type' => 'time', 'label' => 'durée piste', 'dateformat' => 'h:i:s')); ?> 

does knows how that? in advance!

if not php expert can go simple code given below.

add function in controller

public function add() {         if ($this->request->is('post')) {             $this->post->create();              $hours   = $this->data['post']['hours'];             $minutes = $this->data['post']['minutes'];             $seconds = $this->data['post']['seconds'];          $this->request->data['post']['duration']=$hours.':'.$minutes.':'.$seconds;               if ($this->post->save($this->request->data)) {                 $this->session->setflash('your post has been saved.');                 $this->redirect(array('action' => 'index'));             } else {                 $this->session->setflash('unable add post.');             }         }     } 

code in add.ctp file

$hours=array(); for($i=0;$i<13;$i++){   $hours[$i]=$i; }  $ms=array(); for($i=0;$i<60;$i++){   $ms[$i]=$i; }  echo $this->form->input('hours',array('type' => 'select', 'options' => $hours)); echo $this->form->input('minutes',array('type' => 'select', 'options' => $ms)); echo $this->form->input('seconds',array('type' => 'select', 'options' => $ms));
