PHP and update

   hi,

   I am struggling a bit to get a project to update. I'm using PHP with the following (after authenticating correctly): $url = "https://apps.lulu.com/api/publish/v1/update/id/".$content_id; $data = array('publisher' => $metadata, 'api_key' => $apikey, 'auth_token' => $authToken, 'auth_user' =>$authUser); $ch = curl_init($url); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS,$data); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); $response = curl_exec($ch); curl_close($ch); print_r($response); die;

   $metadata is the unaltered json string with the project info obtained using the lulu api.

   However I get the response : {"error_value": "project", "error_type": "KeyError", "additional": "?"}

   Any idea what I am doing wrong?

   {"error_value": "project", "error_type": "KeyError", "additional": "?"}

   sorry, here is a better formatted code block

   1. $url = "https://apps.lulu.com/api/publish/v1/update/id/".$content_id;
   2. $data = array('publisher' => $metadata, 'api_key' => $apikey, 'auth_token' => $authToken,'auth_user' => $authUser);
   3. $ch = curl_init($url);
   4. curl_setopt($ch, CURLOPT_POST, true);
   5. curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
   6. curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   7. curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
   8. curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
   9. $response = curl_exec($ch);
   10. curl_close($ch);
   11. print_r($response);

   You likely simply need to change 'publisher' key to 'project' in the dictionary you are POSTing. The API is looking for 'project' for the data with which to update, which is why you are seeing a KeyError when it is not found.

   ah..thanks. i did that now and it still returns the same error.

   actually the error i get now is:

   {"error_value": "content_id", "error_type": "KeyError", "additional": "?"}

   the code I am using is :

   1. $url = "https://apps.lulu.com/api/publish/v1/update/id/".$content_id;
   2.  $data = array('project' => stripslashes($metadata), 'api_key' => $apikey, 'auth_token' => $authToken,'auth_user' => $authUser);
   3. $ch = curl_init($url);
   4. curl_setopt($ch, CURLOPT_POST, true);
   5. curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
   6. curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   7. curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
   8. curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
   9. $response = curl_exec($ch);
   10. curl_close($ch);
   11. print_r($response);
   12. die;

   Could you post a dump of the $metadata structure? It's hard to know where the problem is parsing the structure without seeing how the data is being supplied.

7. eset – 2 years ago

   sure, this is the raw data what goes into $metadata:

   {"project": {"bibliography": {"category": 0, "publisher": "", "copyright_citation": "", "description": "", "license": "Standard Copyright License", "title": "newscoop tester", "language": "EN", "copyright_year": 2011, "edition": "", "country_code": "US", "authors": [{"first_name": "adam", "last_name": "hyde"}], "keywords": []}, "program_code": null, "access": "private", "drm": false, "allow_ratings": true, "project_type": "softcover", "distribution": ["lulu_marketplace"], "content_id": 10563289, "physical_attributes": {"color": false, "trim_size": "US_TRADE", "binding_type": "perfect", "paper_type": "regular"}, "pricing": [{"total_price": 0.79000000000000004, "product": "download", "royalty": 0, "currency_code": "EUR", "discount_percent": 0}, {"total_price": 9.1400000000000006, "product": "print", "royalty": 0, "currency_code": "EUR", "discount_percent": 0}]}}

   Try removing the outer dictionary, using 'project' only as the key in the POST data key value pairs rather than as a key in the JSON dictionary. So, instead of passing

   api_key=XXX&auth_token=XXX&project={"project": { "bibliography": {...}, ... }
   

   simply pass in

   api_key=XXX&auth_token=XXX&project={"bibliography": {...}, ... }

   thanks!

   ...seems to be the answer. Now I went through a other 'missing field' errors but stuck on: {"error_value": "Missing or invalid delivery id", "error_type": "LInvalidProductException"}

   any idea what that is?

   :)

    actually, i found the error...something to do with incorrect info in the product download pairs...thanks a lot for your help :)
