wordpress - WC_Order does not return the product id by get_items() -


this question has answer here:

i have tried product id , product name following code: 

if ( $query->have_posts() ) {     $order_id = $query->posts[0]->id;     $order = new wc_order( $order_id );     $items = $order->get_items(); }      foreach ( $items $item ) {         $product_id = $item['product_id'];         $product = wc_get_product( $item_id );         $product_name = $item['name'];     }

in above code got product name, return 0 $product_id. there other method this?

i can't find solution this.

my edited version:

when tried this: 

$order_id = $query->posts[0]->id; $order = new wc_order( $order_id ); $items = $order->get_items();  foreach ( $items $item ) {     $item_id = $item['product_id'];     $product_name = $item['name'];     print_r( $item ); exit; }

i got array:

wc_order_item_product object (     [extra_data:protected] => array         (             [product_id] => 0             [variation_id] => 0             [quantity] => 1             [tax_class] =>              [subtotal] => 0             [subtotal_tax] => 0             [total] => 0             [total_tax] => 0             [taxes] => array                 (                     [subtotal] => array                         (                         )                      [total] => array                         (                         )                  )          )      [data:protected] => array         (             [order_id] => 684             [name] => dark skirt "erebos" - large, white             [product_id] => 0             [variation_id] => 0             [quantity] => 1             [tax_class] =>              [subtotal] => 19             [subtotal_tax] => 0             [total] => 19             [total_tax] => 0             [taxes] => array                 (                     [total] => array                         (                         )                      [subtotal] => array                         (                         )                  )          )      [cache_group:protected] => order-items     [meta_type:protected] => order_item     [object_type:protected] => order_item     [id:protected] => 1     [changes:protected] => array         (         )      [object_read:protected] => 1     [default_data:protected] => array         (             [order_id] => 0             [name] =>              [product_id] => 0             [variation_id] => 0             [quantity] => 1             [tax_class] =>              [subtotal] => 0             [subtotal_tax] => 0             [total] => 0             [total_tax] => 0             [taxes] => array                 (                     [subtotal] => array                         (                         )                      [total] => array                         (                         )                  )          )      [data_store:protected] => wc_data_store object         (             [instance:wc_data_store:private] => wc_order_item_product_data_store object                 (                     [internal_meta_keys:protected] => array                         (                             [0] => _order_id                             [1] => _name                             [2] => _product_id                             [3] => _variation_id                             [4] => _quantity                             [5] => _tax_class                             [6] => _subtotal                             [7] => _subtotal_tax                             [8] => _total                             [9] => _total_tax                             [10] => _taxes                             [11] => _product_id                             [12] => _variation_id                             [13] => _qty                             [14] => _tax_class                             [15] => _line_subtotal                             [16] => _line_subtotal_tax                             [17] => _line_total                             [18] => _line_tax                             [19] => _line_tax_data                         )                      [meta_type:protected] => order_item                     [object_id_field_for_meta:protected] => order_item_id                 )              [stores:wc_data_store:private] => array                 (                     [coupon] => wc_coupon_data_store_cpt                     [customer] => wc_customer_data_store                     [customer-download] => wc_customer_download_data_store                     [customer-session] => wc_customer_data_store_session                     [order] => wc_order_data_store_cpt                     [order-refund] => wc_order_refund_data_store_cpt                     [order-item] => wc_order_item_data_store                     [order-item-coupon] => wc_order_item_coupon_data_store                     [order-item-fee] => wc_order_item_fee_data_store                     [order-item-product] => wc_order_item_product_data_store                     [order-item-shipping] => wc_order_item_shipping_data_store                     [order-item-tax] => wc_order_item_tax_data_store                     [payment-token] => wc_payment_token_data_store                     [product] => wc_product_data_store_cpt                     [product-grouped] => wc_product_grouped_data_store_cpt                     [product-variable] => wc_product_variable_data_store_cpt                     [product-variation] => wc_product_variation_data_store_cpt                     [shipping-zone] => wc_shipping_zone_data_store                 )              [current_class_name:wc_data_store:private] => wc_order_item_product_data_store             [object_type:wc_data_store:private] => order-item-product         )      [meta_data:protected] => array         (         )  )

of see [data:protected] array, can see [product_id] 0. problem guess. solution this?

it should be:

foreach ( $items $item ) {     $product = $item->get_product();     $product_id = $product->get_id(); }

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
