Question

I have a link that calls:

<a href="/coupons/print_coupon/<?php echo $coupon['id']; } ?>" id="print"><span style="margin-left:24px;">Print</span></a>

It plugs in the correct id, and my route sends it to the correct view file. I have a debug command to show the entire array for the print page, but I’m getting an empty array. Here is my controller code:

<?php 
class CouponsController extends AppController {
    public $name='Coupons';
    public $uses=array('User', 'Coupon', 'Restaurant');
    public $layout='pagelayout';


    public function print_coupon($name=null) {
      $this->set('title', 'Print your coupon');
      $f=$this->Coupon->find('first', array('conditions'=>array('Coupon.id'=>$this->params['id'])));
      $this->set('name', $f);
    }

}
?>

Here is my Coupon Model:

<?php
class Coupon extends AppModel {
    public $name='Coupon';
    var $belongsTo=array(
    'Restaurant'=>array (
        'className'=>'Restaurant',
        'foreignKey'=>'restaurant_id'
        )
    );
}

?>

and here is my Restaurant Model:

<?php

class Restaurant extends AppModel {
public $name='Restaurant';
var $hasMany=array(
    'Coupon'=>array(
        'className'=>'Coupon',
        'foreignKey'=>'restaurant_id'
        )
);
var $belongsTo=array(
'User'=>array(
'className'=>'User',
'foreignKey'=>'user'
)
);

}


?>

I have tried variations using

 <a href="/coupons/print_coupon/<?php echo $res['Restaurant']['coupon']; } ?>" id="print"><span style="margin-left:24px;">Print</span></a>

along with in my controller:

public function print_coupon($name=null) {
      $this->set('title', 'Print your coupon');
      $f=$this->Coupon->find('first', array('conditions'=>array('Coupon.id'=>$this->params['id'])));
      $this->set('name', $f);
    }

as well as a few others, and whenever I debug($name) I get an empty array. I have had no problems associating Coupon with my other models for other tasks yet, but i think something may be wrong with my Restaurant Model.

For reference, I have these are equal to each other:
Restaurants.coupon = Coupon.id
Coupon.restaurant_id=Restaurant.id

The first anchor code you posted has a curly brace that shouldn’t be there. When you use this:

<a href="/coupons/print_coupon/<?php echo $coupon['id']; ?>" id="print"><span style="margin-left:24px;">Print</span></a>

It should yield some url that’s like this:

/coupons/print_coupon/75

Then in your CouponsController that 75 turns into the $name in your print_coupon parameters (with default routing settings), I recommend changing that to $coupon_id, so your function should look like this:

public function print_coupon($coupon_id) {
  $this->set('title', 'Print your coupon');
  $f=$this->Coupon->find('first', array('conditions'=>array('Coupon.id'=>$coupon_id)));
  $this->set('name', $f);
}

Now $name should be accessible in your view. With this code above, $name won’t exist within the controller.

I don’t think $this->params exists in Cake 2.*. debug($this->request->params); You can get the params from there in the controller, though.
