Question

我正在为WooCommerce写一个插件。我想在WooCommerce购物车中添加多个产品。这是我的代码。

    global $woocommerce;

    $woocommerce->cart->add_to_cart( $_REQUEST['Intel'], $_REQUEST['Intel_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['AMD'], $_REQUEST['AMD_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Desktops_cpu'], $_REQUEST['Desktops_cpu_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Workstation_server_cpu'], $_REQUEST['Workstation_server_cpu_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['intel_Xeon_phi_PCI_Express'], $_REQUEST['intel_Xeon_phi_PCI_Express_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Memory_Ram_non_Ecc'], $_REQUEST['Memory_Ram_non_Ecc_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Memory_Ram_Ecc'], $_REQUEST['Memory_Ram_Ecc_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Desktop_graphics_card'], $_REQUEST['Desktop_graphics_card_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Workstation_graphics_card'], $_REQUEST['Workstation_graphics_card_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Multi_display_video_card'], $_REQUEST['Multi_display_video_card_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Server_graphics_card'], $_REQUEST['Server_graphics_card_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Capture_card'], $_REQUEST['Capture_card_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Cooling'], $_REQUEST['Cooling_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['Sound_Card'], $_REQUEST['Sound_Card_num'] );
    $woocommerce->cart->add_to_cart( $_REQUEST['SSD'], $_REQUEST['SSD_num'] );

产品已添加到购物车中，但后来我有错误！

WooCommerce以编程方式将多个产品添加到购物车
