product export error : Unsupported operand type

Question

How can I solve this :

Unsupported operand types in C:\wamp\www\abc\app\code\core\Mage\ImportExport\Model\Export\Entity\Product.php on line 875

It occurs when trying to export products via the admin panel system -> import/export menu.

Answer 1

Magento have a patch for this issue as SUPEE-6511.

Ask magento support for the official patch file, however the change provided is simple enough. Around line 875-ish in app/code/core/Mage/ImportExport/Model/Export/Entity/Product.php you should update as follows.

-    $dataRow += $stockItemRows[$productId];
+    if (isset($stockItemRows[$productId])) {
+        $dataRow = array_merge($dataRow, $stockItemRows[$productId]);
+    }

Answer 2

Looking at the rest of the $dataRow manipulations that line does look odd.

Try replacing

875:    $dataRow += $stockItemRows[$productId];

with

$dataRow = array_merge($dataRow,$stockItemRows[$productId]);

However, directly modifying core files is bad so you should override it but a quick test should show if it is working.

Answer 3

Assuming that the problem line (as you didn't specify your Magento version) looks something like this:

875:    $dataRow += $stockItemRows[$productId];

My first thing to check would be the version of php you are using. I do not think that, for pre PHP v5.2 (and some of v5.2...), the += operand is not supported for arrays, which this action is.

Answer 4

This worked great: $dataRow = array_merge($dataRow,$stockItemRows[$productId]);

Answer 5

This is perfectly work for me. Thanks.

$dataRow = array_merge($dataRow,$stockItemRows[$productId]);
