Unable to create custom collection of products via Shopify API post

Question

I'm trying to create a custom product collection using Sandeep Shetty's shopify.php. Ive been able to make other functional API calls- displaying products and carts etc. But Im unable to create a custom collection with a 'known-good' list of product ids. Heres my code:

$charge = array
    (
        "custom_collection"=>array
        (
            "title"=>"ThisTest",
            "collects"=>array(
                "product_id"=>96525818,
                "product_id"=>96393246
            )
        )
    );
    try
    {
        // All requests accept an optional fourth parameter, that is populated with the response headers.
        $my_collect = $shopify('POST', '/admin/custom_collections.json', $charge, $response_headers);

        // API call limit helpers
        echo shopify_calls_made($response_headers); // 2
        echo shopify_calls_left($response_headers); // 298
        echo shopify_call_limit($response_headers); // 300

    }
    catch (ShopifyApiException $e)
    {            
        echo "doh";
        print_r($e);
    }

}

I'm getting the following error back.

ShopifyApiException Object

) Im working from example code shopfiy provides but not getting very far. Thank you for any help.

Answer 1

Checking in the logs, it looks like the 'collects' attribute wasn't actually sent as an array which you specified in your $charge variable. After looking up the request_id f22337df8773ff4fa2f9f384ca21f133, this is the request you had sent:

{"custom_collection"=>{"title"=>"ToddTest", "collects"=>{"product_id"=>96393246}}}

The request should look like this to work:

{"custom_collection"=>{"title"=>"ToddTest", "collects"=>[{"product_id"=>96393246}]}}

Note that collects is an array.
