Magento SOAP (v1) API causes fatal error getSelect() after completed order

Question

I'm trying to complete my software which interacting with the Magento API and another external API (REST). In this project I forwarding the orders of the other shop system towards Magento and I'm able to create a order (yeha!).

Unfortunately, Magento seems to cause an fatal error after the successful order. That's a problem because I've to convert about hundrets orders...

Fatal error: Uncaught SoapFault exception: [SOAP-ENV:Server] Call to a member function getSelect() on a non-object in /var/orders.php:280
Stack trace:
#0 /var/orders.php: SoapClient->__call('call', Array)
#1 /var/orders.php: SoapClient->call('6ceb613d278de9e...', 'cart.order', Array)
#2 /var/orders.php: complete_order(Array, 3)
#3 /var/orders.php: new_orders(Object(mysqli))

Does anybody have any idea how to solve that?

The involved line in the PHP file:

 $result = $client->call($session, 'cart.info', $shopping_cart_id);

The whole PHP code:

function complete_order($val,$i=1) {
 if($i == 3) {
 $client = new SoapClient(MAGENTO_HOST.'/api/soap/?wsdl');
 $session = $client->login(MAGENTO_API_USER, MAGENTO_API_KEY);
 # Choose a store id 
 $store_id = $client->call($session, 'category.currentStore', MAGENTO_STORE_ID);
 # Create a new shopping cart
 $shopping_cart_id = $client->call( $session, 'cart.create', $store_id );
 # Add products to cart #
 $product_for_cart = array(
 array(
 "sku" => "TOPP19600",
 "qty" => 2,
 "options" => null
 ),
 array(
 "sku" => "TOPP19601",
 "qty" => 1,

 $val['items'] = $product_for_cart;
 foreach($val['items'] AS $item) {
 $filters = array( 
 'status' => array( '=' => 1 ), 
 'sku' => array( '=' => $item['sku']), 
 ); 
 $result = $client->call($session, 'catalog_product.list', array($filters,$store_id));
 if($result != NULL AND count($result)> 0) {
 $product_for_cart[] = array('product_id' => $result[0]['product_id'], 'qty' => $item['qty']);
 } else {
 # unknown product found #
 echo('Unknown product'); 
 }
 }
 # Customer information (as guest) #
 $customer = array(
 'mode' => 'guest',

 );
 $resultCustomerSet = $client->call($session, 'cart_customer.set', array($shopping_cart_id, $customer, $store_id) );
 // Set customer addresses, for example guest's addresses
 $arrAddresses = array(

 )
 );
 $add_product_to_cart = $client->call($session,"cart_product.add",array($shopping_cart_id, $product_for_cart));
 $resultCustomerAddresses = $client->call($session,"cart_customer.addresses",array($shopping_cart_id, $arrAddresses, $store_id));

• Fabian Blechschmidt: Please post the code of orders.php, because it seems as the error is thrown there in line 280.
• EaglePsyX: @FabianBlechschmidt I added the "bad" line.
• Fabian Blechschmidt: Ok, I slowly understand. Than it is time to dig in magento. This is no standard behaviour, therefore I think we can't help you, because the problem is not reproducable
• EaglePsyX: That would not be the first time. In the first approach I was not able to add a customer because Magento ask for a "day of birth", which is nowhere noticed (espacially not in the Magento documentations). Therefore I digged several minutes the PHP code of Magento and was able to identify the missing veriable "dob". Is there a workaround to "ignore" the fatal error and continue the script?
• Fabian Blechschmidt: Nope, Fatal errors can't be catched.

Answer 1

I understand what's wrong....

I have a plugin (TrustedShop) who use an observer on 'checkout_type_onepage_save_order_after'

I remove in the plugin the part :

 <checkout_type_onepage_save_order_after>
 <observers>
 <buyerprotect>
 <type>singleton</type>
 <class>Symmetrics_Buyerprotect_Model_Observer</class>
 <method>registerTsSoapModel</method>
 </buyerprotect>
 </observers>
 </checkout_type_onepage_save_order_after>

And it's fine...
