php - Access a Controller return value in a View -

in controller have method

<?php  function test($value){                    $products = $this->model->getproducts($id);      for($i=0; $i < count($products); $i++){          foreach ($products[$i] $key => $value) {             return $value;         }     } } ?>   

how can access inside view?

if generate variable in controller, , want access in view, can use

$this->set('value', $value); 

this allow use $value in relevant view well.

if want access function view, don't want want put function in controller, in helper. (as rule of thumb, put functions want accessible views in helpers, , functions want accessible controller in components.) might worth reading more on helpers in cake cookbook etc if don't know start!

edit: getting relevant values of loop, try like:

$products = $this->model->getproducts($id); $results = array();  for($i=0; $i < count($products); $i++){      foreach ($products[$i] $key => $value) {         $results[] = $value;     }  }  $this->set(compact('results'));
