Woocommerce在添加新产品之前删除购物车

Question

$woocommerce->cart->add_to_cart( $product_ID, $quantity=1 )

我的产品创建：

function customcart() {

  if (isset($_POST["addcustomcarts"])) {

    global $woocommerce;
    $my_post = array(
      'post_title'    => 'Design selv skilt',
      'post_content'  => '<div class="col-md-12">Dette er et design selv skilt, tjek egenskaber på produktet for at se hvad kunden har bestilt.</div>',
      'post_status'   => 'publish',
      'post_author'   => 1,
      'post_type'     => 'product'
    );

    // Insert the post into the database
    $product_ID = wp_insert_post( $my_post );

    $filteredData=substr($_POST['img_val'], strpos($_POST['img_val'], ",")+1);

    //Decode the string
    $unencodedData=base64_decode($filteredData);

    //Save the image
    file_put_contents('img' . $product_ID . '.png', $unencodedData);

    if ( $product_ID ){
      wp_set_object_terms( $product_ID, 'design-selv-skilte', 'product_cat' );
      add_post_meta($product_ID, '_regular_price', $_POST["priceInput"] );
      add_post_meta($product_ID, '_price', $_POST["priceInput"] );
      add_post_meta($product_ID, '_stock_status', 'instock' );
      //add_post_meta($product_ID, '_manage_stock', 'yes' );    
      //add_post_meta($product_ID, '_stock', '10' ); 
      add_post_meta($product_ID, '_sku', 'designselvskilt-' . $product_ID );   
      add_post_meta($product_ID, '_visibility', 'hidden' );
      add_post_meta($product_ID, 'tekst-paa-linje-1', $_POST["textInput"] );
      add_post_meta($product_ID, 'tekst-paa-linje-2', $_POST["text2Input"] );
      add_post_meta($product_ID, 'stoerrelse', $_POST["størrelseInput"] );
      add_post_meta($product_ID, 'form', $_POST["formInput"] );
      add_post_meta($product_ID, 'farve', $_POST["farveInput"] );
      add_post_meta($product_ID, 'type-skilt', $_POST["typeInput"] );
      add_post_meta($product_ID, 'fastgoering', $_POST["fastgøringInput"] );
      add_post_meta($product_ID, 'font', $_POST["fontInput"] );
      add_post_meta($product_ID, 'linje-1-font-size', $_POST["fontSizeLine1Input"] );
      add_post_meta($product_ID, 'linje-2-font-size', $_POST["fontSizeLine2Input"] );
      add_post_meta($product_ID, 'product_image_gallery', $_POST["img_val"]);
      add_post_meta($product_ID, 'product_image_url', 'img' . $product_ID . '.png');  
      require_once(ABSPATH . 'wp-admin/includes/media.php');
      require_once(ABSPATH . 'wp-admin/includes/file.php');
      require_once(ABSPATH . 'wp-admin/includes/image.php');
      $home = home_url();
      $url = $home . '/img' . $product_ID . '.png';
      $post_id = $product_ID;
      $desc = $_POST["textInput"];
      $image = media_sideload_image($url, $post_id, $desc, src );

              function getImageId( $image ) {
            // Split the $url into two parts with the wp-content directory as the separator
            $parsed_url  = explode( parse_url( WP_CONTENT_URL, PHP_URL_PATH ), $image );

            // Get the host of the current site and the host of the $url, ignoring www
            $this_host = str_ireplace( 'www.', '', parse_url( home_url(), PHP_URL_HOST ) );
            $file_host = str_ireplace( 'www.', '', parse_url( $image, PHP_URL_HOST ) );

            // Return nothing if there aren't any $url parts or if the current host and $url host do not match
            if ( ! isset( $parsed_url[1] ) || empty( $parsed_url[1] ) || ( $this_host != $file_host ) ) {
                return;
            }

            // Now we're going to quickly search the DB for any attachment GUID with a partial path match
            // Example: /uploads/2013/05/test-image.jpg
            global $wpdb;

            $attachment = $wpdb->get_col( $wpdb->prepare( "SELECT ID FROM {$wpdb->prefix}posts WHERE guid RLIKE %s;", $parsed_url[1] ) );

            // Returns null if no attachment is found
            return $attachment[0];
        }    

      set_post_thumbnail($post_id, getImageId( $image ));    

      $woocommerce->cart->add_to_cart( $product_ID, $quantity=1 );

       wp_redirect( '/kurv' ); exit;

    }
  }

}

似乎您并不是唯一一个发现需要首先初始化购物车才能从中获得一致和预期的行为的人：

• 如何正确初始化Woocommerce购物车

我建议你考虑加入以下内容：

$woocommerce->session->set_customer_session_cookie(true);

$woocommerce->cart->add_to_cart( $product_ID, $quantity=1 );

$woocommerce->cart->add_to_cart( $product_ID, TRUE );

你的意思是：

$woocommerce->cart->add_to_cart( $product_ID, 1 );

但是，我的猜测是，您使用了方法签名，该签名表明第二个参数是可选的，并且如果省略，则默认值为整数1，在这种情况下，您可以使用以下命令使其更简单：

$woocommerce->cart->add_to_cart( $product_ID );

如果只想传递变量，则需要如下所示

$quantity = 1;
// ... any other code
$woocommerce->cart->add_to_cart( $product_ID, $quantity );
