php - Unable to return 'attribute' data in Woocomerce -


pa_i trying dog products' attribute data in order compare attribute between items in cart. however, cannot access data. following code returns following on var_dump command:

c:\wamp\www\wizstaginglocal\wp-content\plugins\code-snippets\php\snippet-ops.php(426) : eval()'d code:17:boolean false

in other words nothing

code:

add_action('woocommerce_before_cart', 'wiz_scale_woocommerce_before_cart');  function wiz_scale_woocommerce_before_cart() {     foreach(wc() -> cart -> get_cart() $cart_item_key => $cart_item) {         // here wc_product object         $product = $cart_item['data'];         echo "my product id {$cart_item['product_id']} \n";          $attributes = $product -> get_attributes();         foreach($attributes $taxonomy => $value) {             // wp_term object             $term_obj = get_term_by('pa_1_scale', $value, $taxonomy);             $term_name = $term_obj -> name;          }         echo '<pre>';         var_dump($term_obj);         echo '</pre>';     } }

at var_dump $attributes shows, relevant slug:

array (size=3).... 'pa_1_scale' => object(wc_product_attribute)[1383] protected 'data' => array (size=6) 'id' => int 1 'name' => string 'pa_1_scale' (length=10) 'options' => array (size=1) ... 'position' => int 2 'visible' => boolean true 'variation' => boolean false

i became aware of this post: reason?

the attribute data in serialized, cannot find way extract it. work around successful write sql query wp database.

function mycustomfunc_retrieve_attribute_for product() { foreach(wc() -> cart -> get_cart() $cart_item_key => $cart_item) {     $product = $cart_item['product_id'];    // perform wpdb search global $wpdb; $myatt = $wpdb->get_var(     $wpdb->prepare(     "select distinct     t.name 'term name'         wiz_posts p     inner join     wiz_term_relationships tr on p.id = tr.object_id     inner join     wiz_term_taxonomy tt on tt.term_taxonomy_id = tr.term_taxonomy_id     inner join     wiz_terms t on t.term_id = tt.term_id         p.post_type = 'product'     ,     p.id = %d     ,     tt.taxonomy = 'myslugname'     ",     $product     )     );   echo "my product id {$product} , attribute {$myatt} \n";  }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
