[hmvr414]

Hi,

 

I followed the guide to setup prestashop webservices (http://doc.prestashop.com/display/PS16/Using+the+PrestaShop+Web+Service), i create a key with permission to read categories and products and i was able to get the list of items,

api/categories

but when try to get the details of a single item i get an error 500

api/categories/1

enabling the debug output i get the following error description

Fatal error: Uncaught Error: Function name must be a string in /Applications/MAMP/htdocs/prestatest/classes/webservice/WebserviceOutputBuilder.php:542

Thanks for any comment.

 

On line 542 mentioned above, try changing 

 $field['value'] = $object->$field['getter']();

to: 

 $field['value'] = $object->($field['getter'])();
