休息 API 根据 woocommerce 中的用户 ID 将产品存储在购物车中

Question

我发现只有少数人接受的相同的相关参考是下面提到的代码，但没有会话存储在选项 table 中，带有以下键 '_wc_session_'.$user_id

function add_products_programmatically($user_id) {

// Get the current session data and saved cart
$wc_session_data = get_option('_wc_session_'.$user_id);

// Get the persistent cart
$full_user_meta = get_user_meta($user_id,'_woocommerce_persistent_cart', true);

// Create a new WC_Cart instance and add products programmatically
$cart = get_new_cart_with_products();

// If there is a current session cart, overwrite it with the new cart
if($wc_session_data) {
    $wc_session_data['cart'] = serialize($cart->cart_contents);
    update_option('_wc_session_'.$user_id, $wc_session_data);
}

// Overwrite the persistent cart with the new cart data
$full_user_meta['cart'] = $cart->cart_contents;
update_user_meta($user_id, '_woocommerce_persistent_cart', $full_user_meta);
}

在对 woo-commerce 使用持久购物车的方式进行大量研究后，我创建了一个可行的解决方案。

function woocomm_add_to_cart($param) {

global $wpdb;
$user_id = $param['user_id'];
$objProduct = new WC_Session_Handler();

$wc_session_data = $objProduct->get_session($user_id);

// Get the persistent cart may be _woocommerce_persistent_cart can be in your case check in user_meta table
$full_user_meta = get_user_meta($user_id,'_woocommerce_persistent_cart_1',true);

// create new Cart Object
$cartObj = new WC_Cart();

// Add old cart data to newly created cart object
if($full_user_meta['cart']) {
    foreach($full_user_meta['cart'] as $sinle_user_meta) {
        $cartObj->add_to_cart( $sinle_user_meta['product_id'], $sinle_user_meta['quantity']  );
    }
}

// Add product and quantities coming in request to the new cart object
if($param['products']){
    foreach($param['products'] as $prod) {
        $cartObj->add_to_cart( $prod['product_id'], $prod['quantity']  );
    }
}

$updatedCart = [];
foreach($cartObj->cart_contents as $key => $val) {
    unset($val['data']);
    $updatedCart[$key] = $val;
}

// If there is a current session cart, overwrite it with the new cart
if($wc_session_data) {
    $wc_session_data['cart'] = serialize($updatedCart);
    $serializedObj = maybe_serialize($wc_session_data);


    $table_name = 'wp_woocommerce_sessions';

    // Update the wp_session table with updated cart data
    $sql ="UPDATE $table_name SET 'session_value'= '".$serializedObj."', WHERE  'session_key' = '".$user_id."'";

    // Execute the query
    $rez = $wpdb->query($sql);
}

// Overwrite the persistent cart with the new cart data
$full_user_meta['cart'] = $updatedCart;
update_user_meta($user_id, '_woocommerce_persistent_cart_1', $full_user_meta);

$response = [
    'status' => true,
    'message' => 'Products successfully added to cart'
];

return rest_ensure_response($response);


}

这是其余 API 的请求 json 数据：

{"user_id": 15, "products" : [{"product_id":"81","quantity":"0.5"},{"product_id":"1817","quantity":"0.5"}]}

我对以前的代码做了一些更改，因为这段代码不能独立地与我一起工作。

我已经为我的 Vue.js 应用程序创建了 Rest API。
创建路由并创建函数并粘贴此代码用作添加到购物车

这也可以在添加时更新web端用户的session 来自移动端

if (checkloggedinuser()) {

    include_once WC_ABSPATH . 'includes/wc-cart-functions.php';
    include_once WC_ABSPATH . 'includes/wc-notice-functions.php';
    include_once WC_ABSPATH . 'includes/wc-template-hooks.php';
    global $wpdb;
    $user_id = get_current_user_id();
    WC()->session = new WC_Session_Handler();
    WC()->session->init();

    $wc_session_data = WC()->session->get_session($user_id);

    // Get the persistent cart may be _woocommerce_persistent_cart can be in your case check in user_meta table
    $full_user_meta = get_user_meta($user_id,'_woocommerce_persistent_cart_1',true);
    WC()->customer = new WC_Customer( get_current_user_id(), true );
    // create new Cart Object
    WC()->cart = new WC_Cart();
    // return $full_user_meta;
    // Add old cart data to newly created cart object
    if($full_user_meta['cart']) {
        foreach($full_user_meta['cart'] as $sinle_user_meta) {
             WC()->cart->add_to_cart( $sinle_user_meta['product_id'], $sinle_user_meta['quantity']  );
        }
    }

    WC()->cart->add_to_cart( $request['product_id'], $request['quantity']  );

    $updatedCart = [];


    foreach(WC()->cart->cart_contents as $key => $val) {
        unset($val['data']);
        $updatedCart[$key] = $val;
        $updatedCart[$key]['file'] = "hello file herer";  
    }

    // If there is a current session cart, overwrite it with the new cart
    if($wc_session_data) {
        $wc_session_data['cart'] = serialize($updatedCart);
        $serializedObj = maybe_serialize($wc_session_data);
        $table_name = 'wp_woocommerce_sessions';

        // Update the wp_session table with updated cart data
        $sql ="UPDATE $table_name SET 'session_value'= '".$serializedObj."', WHERE  'session_key' = '".$user_id."'";

        // Execute the query
        $rez = $wpdb->query($sql);
    }

    // Overwrite the persistent cart with the new cart data
    $full_user_meta['cart'] = $updatedCart;
    update_user_meta($user_id, '_woocommerce_persistent_cart_1', $full_user_meta);

     return array(
        'success' => false,
        'responsecode' => 403,
        "message" => "Products successfully added to cart",
        "data" => [],
    );

}else{
     return array(
        'success' => false,
        'responsecode' => 403,
        "message" => "Please Logged In to get Data",
        "data" => [],
    );
}
