一次向WooCommerce购物车添加多个商品

时间：2017-03-03 04:57:53

标签： php woocommerce web

我有3个不同商品的ID，我想添加到购物车中。 我可以使用next()但是当我想添加3个项目时我无法做到。我可以添加任何功能/脚本来将此功能添加到我的购物网站吗？

我尝试在https://url.com/shop/cart/?add-to-cart=3001之后添加&并尝试添加新值，但是GET被覆盖了吗？： add-to-cart

我找到了答案！

只需将以下脚本添加到主题的functions.php中：

'NA'

然后您只需使用function woocommerce_maybe_add_multiple_products_to_cart() { // Make sure WC is installed, and add-to-cart qauery arg exists, and contains at least one comma. if ( ! class_exists( 'WC_Form_Handler' ) || empty( $_REQUEST['add-to-cart'] ) || false === strpos( $_REQUEST['add-to-cart'], ',' ) ) { return; } // Remove WooCommerce's hook, as it's useless (doesn't handle multiple products). remove_action( 'wp_loaded', array( 'WC_Form_Handler', 'add_to_cart_action' ), 20 ); $product_ids = explode( ',', $_REQUEST['add-to-cart'] ); $count = count( $product_ids ); $number = 0; foreach ( $product_ids as $product_id ) { if ( ++$number === $count ) { // Ok, final item, let's send it back to woocommerce's add_to_cart_action method for handling. $_REQUEST['add-to-cart'] = $product_id; return WC_Form_Handler::add_to_cart_action(); } $product_id = apply_filters( 'woocommerce_add_to_cart_product_id', absint( $product_id ) ); $was_added_to_cart = false; $adding_to_cart = wc_get_product( $product_id ); if ( ! $adding_to_cart ) { continue; } $add_to_cart_handler = apply_filters( 'woocommerce_add_to_cart_handler', $adding_to_cart->product_type, $adding_to_cart ); /* * Sorry.. if you want non-simple products, you're on your own. * * Related: WooCommerce has set the following methods as private: * WC_Form_Handler::add_to_cart_handler_variable(), * WC_Form_Handler::add_to_cart_handler_grouped(), * WC_Form_Handler::add_to_cart_handler_simple() * * Why you gotta be like that WooCommerce? */ if ( 'simple' !== $add_to_cart_handler ) { continue; } // For now, quantity applies to all products.. This could be changed easily enough, but I didn't need this feature. $quantity = empty( $_REQUEST['quantity'] ) ? 1 : wc_stock_amount( $_REQUEST['quantity'] ); $passed_validation = apply_filters( 'woocommerce_add_to_cart_validation', true, $product_id, $quantity ); if ( $passed_validation && false !== WC()->cart->add_to_cart( $product_id, $quantity ) ) { wc_add_to_cart_message( array( $product_id => $quantity ), true ); } } } // Fire before the WC_Form_Handler::add_to_cart_action callback. add_action( 'wp_loaded', 'woocommerce_maybe_add_multiple_products_to_cart', 15 ); 一次添加多个项目即可。在不同的ID之间加上逗号。

与其他答案相同，支持多个数量。

示例网址：http://store.amitbend.com/cart/?add-to-cart=188,187,189&quantities=3,2,1 


function woocommerce_maybe_add_multiple_products_to_cart() {
// Make sure WC is installed, and add-to-cart qauery arg exists, and contains at least one comma.
if ( ! class_exists( 'WC_Form_Handler' ) || empty( $_REQUEST['add-to-cart'] ) || false === strpos( $_REQUEST['add-to-cart'], ',' ) ) {
    return;
}

// Remove WooCommerce's hook, as it's useless (doesn't handle multiple products).
remove_action( 'wp_loaded', array( 'WC_Form_Handler', 'add_to_cart_action' ), 20 );

$product_ids = explode( ',', $_REQUEST['add-to-cart'] );
$quantities = explode( ',', $_REQUEST['quantities'] );

$count       = count( $product_ids );
$number      = 0;

foreach ( $product_ids as $product_id ) {
    if ( ++$number === $count ) {
        // Ok, final item, let's send it back to woocommerce's add_to_cart_action method for handling.

以防其他人像我一样寻找此功能。我更新了顶部评论的代码，使其可以与woocommerce 3.5.3一起使用

    // adds support for multi add to cart for 3rd party cart plugin
function woocommerce_maybe_add_multiple_products_to_cart() {
    // Make sure WC is installed, and add-to-cart qauery arg exists, and contains at least one comma.
    if ( ! class_exists( 'WC_Form_Handler' ) || empty( $_REQUEST['add-to-cart'] ) || false === strpos( $_REQUEST['add-to-cart'], ',' ) ) {
        return;
    }

    // Remove WooCommerce's hook, as it's useless (doesn't handle multiple products).
    remove_action( 'wp_loaded', array( 'WC_Form_Handler', 'add_to_cart_action' ), 20 );

    $product_ids = explode( ',', $_REQUEST['add-to-cart'] );
    $count       = count( $product_ids );
    $number      = 0;

    foreach ( $product_ids as $product_id ) {
        if ( ++$number === $count ) {
            // Ok, final item, let's send it back to woocommerce's add_to_cart_action method for handling.
            $_REQUEST['add-to-cart'] = $product_id;

            return WC_Form_Handler::add_to_cart_action();
        }

        $product_id        = apply_filters( 'woocommerce_add_to_cart_product_id', absint( $product_id ) );
        $was_added_to_cart = false;

        $adding_to_cart    = wc_get_product( $product_id );

        if ( ! $adding_to_cart ) {
            continue;
        }

        // only works for simple atm
        if ( $adding_to_cart->is_type( 'simple' ) ) {

            // quantity applies to all products atm
            $quantity          = empty( $_REQUEST['quantity'] ) ? 1 : wc_stock_amount( $_REQUEST['quantity'] );
            $passed_validation = apply_filters( 'woocommerce_add_to_cart_validation', true, $product_id, $quantity );

            if ( $passed_validation && false !== WC()->cart->add_to_cart( $product_id, $quantity ) ) {
                wc_add_to_cart_message( array( $product_id => $quantity ), true );
            }

        }
    }
}
add_action( 'wp_loaded', 'woocommerce_maybe_add_multiple_products_to_cart', 15 );

答案 4 :(得分：0)

我对此采取了不同的方法。我没有杀死WC_Form_Handler，而是使用它！我为每个产品运行它。对我来说，这似乎更简单。

您可以单独使用此功能，也可以与常规的购物车一起使用。

http://example.com?add-more-to-cart=1000,10001,10002

http://example.com?add-to-cart=1000&add-more-to-cart=10001,10002 

class add_more_to_cart {

    private $prevent_redirect = false; //used to prevent WC from redirecting if we have more to process

    function __construct() {
        if ( ! isset( $_REQUEST[ 'add-more-to-cart' ] ) ) return; //don't load if we don't have to
        $this->prevent_redirect = 'no'; //prevent WC from redirecting so we can process additional items
        add_action( 'wp_loaded', [ $this, 'add_more_to_cart' ], 21 ); //fire after WC does, so we just process extra ones
        add_action( 'pre_option_woocommerce_cart_redirect_after_add', [ $this, 'intercept_option' ], 9000 ); //intercept the WC option to force no redirect
    }

    function intercept_option() {
        return $this->prevent_redirect;
    }

    function add_more_to_cart() {
        $product_ids = explode( ',', $_REQUEST['add-more-to-cart'] );
        $count       = count( $product_ids );
        $number      = 0;

        foreach ( $product_ids as $product_id ) {
            if ( ++$number === $count ) $this->prevent_redirect = false; //this is the last one, so let WC redirect if it wants to.
            $_REQUEST['add-to-cart'] = $product_id; //set the next product id
            WC_Form_Handler::add_to_cart_action(); //let WC run its own code
        }
    }
}
new add_more_to_cart;

在这里，我已强制$_REQUEST[ 'add-to-cart' ]取得预期的产品ID。覆盖全局变量听起来不是很好的方法，但它保留了DRY方法，并使所有本机函数对用户可用。

add_action( 'wp_loaded', 'add_multiple_to_cart_action', 20 );

function add_multiple_to_cart_action() {
    if ( ! isset( $_REQUEST['multiple-item-to-cart'] ) || false === strpos( wp_unslash( $_REQUEST['multiple-item-to-cart'] ), '|' ) ) { // phpcs:ignore WordPress.Security.NonceVerification.NoNonceVerification, WordPress.Security.ValidatedSanitizedInput.InputNotSanitized
            return;
        }

    wc_nocache_headers();

    $product_ids        = apply_filters( 'woocommerce_add_to_cart_product_id', wp_unslash( $_REQUEST['multiple-item-to-cart'] ) ); // phpcs:ignore WordPress.Security.NonceVerification.NoNonceVerification
    $product_ids = explode( '|', $product_ids );
    if( ! is_array( $product_ids ) ) return;

    $product_ids = array_map( 'absint', $product_ids );
    $was_added_to_cart = false;
    $last_product_id = end($product_ids);
    //stop re-direction
    add_filter( 'woocommerce_add_to_cart_redirect', '__return_false' );
    foreach ($product_ids as $index => $product_id ) {
        $product_id = absint(  $product_id  );
        if( empty( $product_id ) ) continue;
        $_REQUEST['add-to-cart'] = $product_id;
        if( $product_id === $last_product_id ) {

            add_filter( 'option_woocommerce_cart_redirect_after_add', function() { 
                return 'yes'; 
            } );
        } else {
            add_filter( 'option_woocommerce_cart_redirect_after_add', function() { 
                return 'no'; 
            } );
        }

        WC_Form_Handler::add_to_cart_action();
    }
}

正确的语法是

add-to-cart=product1id:quantity,product2id:quantity

这是代码 https://www.webroomtech.com/woocommerce-add-multiple-products-to-cart-via-url/

他们没有在教程中显示这种数量语法，我在代码中发现了它。

WooCommerce 4.0，一种更简单的方法是使用 template_redirect 钩子，它会在流程早期触发。理论上，您可以解码 URL 并将多个项目添加到购物车或 POST 表单并处理 POST。最简单的形式是：

add_action( 'template_redirect', function() {
    
    if( ! isset( $_POST['products'] ) ) {
        return;
    }
    
    $products = array_filter( $_POST['products'] );
    
    foreach( $products as $product_id => $quantity ) {
        WC()->cart->add_to_cart( $product_id, $quantity );
    }
    
} );

如果您不想编码任何东西，您可以创建一个分组产品，将要添加到购物车的所有产品添加为链接产品。

然后网址如下：

https://url.com/shop/cart/?add-to-cart=3001&quantity[2002]=1&quantity[1001]=1
  • 3001 = 分组产品 ID
  • 2002 = 链接的产品 1 id
  • 1001 = 链接的 Product2 id

不要忘记指定数量。

此外，您可以将目录可见性更改为“隐藏”，这样分组产品就不会出现在您的商店中。
