Deleting a Line Item Programmatically
Hi
I am getting the error message below when trying to use commerce_cart_order_product_line_item_delete in the commerce_cart_line_item_refresh hook.
EntityMetadataWrapperException: Unable to get the data property type as the parent data structure is not set. in EntityStructureWrapper->getPropertyValue() (line 442 of C:\repo\docroot\profiles\commerce_kickstart\modules\contrib\entity\includes\entity.wrapper.inc).
I have also included my code below. Please help?
function htconference_commerce_cart_line_item_refresh($line_item, $order_wrapper) {
//dprint_r($line_item);
if (isset($line_item->field_discount_flag)) {
/*
* Check if a discount has been applied (this occurs if the product has a discount applied
* to the field_discount line item attribute (see below)
*/
if ($line_item->field_discount_flag[LANGUAGE_NONE][0]['value'] == 5){
$qty = $line_item->quantity;
$price = $line_item->commerce_unit_price[LANGUAGE_NONE][0]['amount'] - $line_item->field_discount_flag[LANGUAGE_NONE][0]['value']*100;
$line_item->commerce_unit_price[LANGUAGE_NONE][0]['data']['components'][0]['price']['amount'] = $price;
$line_item->commerce_unit_price[LANGUAGE_NONE][0]['amount'] = $price;
$line_item->commerce_total[LANGUAGE_NONE][0]['data']['components'][0]['price']['amount'] = $qty*$price;
$line_item->commerce_total[LANGUAGE_NONE][0]['amount'] = $qty*$price;
commerce_line_item_save($line_item);
entity_get_controller('commerce_line_item')->resetCache(array($line_item->line_item_id));
