Using a variable in PHP controller

[MBroadbridge]

Hi,

 

I have installed a custom fields module on v1.7.3 to assign a 'postcode' to each 'product' (the products are houses for sale). I need to display a ' x miles from you' on each product in the product list. So far I have nearly got it, I have just got to get the custom field module variable '{$product.dwf_postcode}' into the CategoryController.php file.

 

My CategoryController.php currently looks like this:

 

$postcode1 = $_POST['searcher_postcode']; // generated by a simple POST form on the category page, this is working correctly
        $postcode2 = {$product.dwf_postcode} // property postcode here pulled from the custom module, this is not working due to the brackets
        

$url = "https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=$postcode1&destinations=$postcode2&key=[MY API KEY HERE, REMOVE FOR DISPLAY PURPOSES]";

    //fetch json response from googleapis.com:
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $response = json_decode(curl_exec($ch), true);
    //If google responds with a status of OK
    //Extract the distance text:
    if($response['status'] == "OK"){
        $dist = $response['rows'][0]['elements'][0]['distance']['text'];
        echo "<p><i class='fa fa-map-marker'></i> $dist</p>";
    }

        
           }

 

 

 

Any help appreciated!
