如果他们的购物篮中没有特定的产品类别,我想阻止任何客户前往结帐。我还想告诉他们一个错误消息,他们需要添加某个产品。我找到了一些代码,但无法工作。我已经将它作为代码片段添加到我的Wordpress安装中但是它不起作用并且即使我已打开调试也没有错误消息。以下是我在Github中找到的代码,可能需要修改才能使其正常工作:
function sv_wc_prevent_checkout_for_category() {
// set the slug of the category for which we disallow checkout
$category = 'sibling';
// get the product category
$product_cat = get_term_by( 'slug', $category, 'product_cat' );
// sanity check to prevent fatals if the term doesn't exist
if ( is_wp_error( $product_cat ) ) {
return;
}
$category_name = '<a href="' . get_term_link( $category, 'product_cat' ) . '">' . $product_cat->name . '</a>';
// check if this category is the only thing in the cart
if ( sv_wc_is_category_alone_in_cart( $category ) ) {
// render a notice to explain why checkout is blocked
wc_add_notice( sprintf( 'Hi there! Looks like your cart only contains products from the %1$s category – you must purchase a product from another category to check out.', $category_name ), 'error' );
}
}
add_action( 'woocommerce_check_cart_items', 'sv_wc_prevent_checkout_for_category' );
/**
* Checks if a cart contains exclusively products in a given category
*
* @param string $category the slug of the product category
* @return bool - true if the cart only contains the given category
*/
function sv_wc_is_category_alone_in_cart( $category ) {
// check each cart item for our category
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
// if a product is not in our category, bail out since we know the category is not alone
if ( ! has_term( $category, 'product_cat', $cart_item['data']->id ) ) {
return false;
}
}
// if we're here, all items in the cart are in our category
return true;
}
所以如果'兄弟'类别是购物车中的唯一商品,我希望停止结帐(带错误消息)。我有一个“标准”类别,必须在客户进入结账前进入购物篮。希望这是有道理的。

这里有一个解决方案可以解决这个问题。特别是有两个主要功能(最后一个):
在
your_mandatory_category_slug()
函数中强制类别slug之前定义。
这是代码:
// Function that define the mandatory product category
function your_mandatory_category_slug(){
// DEFINE HERE the SLUG of the needed product category
$category = 'clothing';
return $category;
}
// Conditional function that returns true if the mandatory product category is in cart
function has_mandatory_category(){
$category_needed = your_mandatory_category_slug();
$has_cat = false;
// Iterrating each item in cart and detecting…
foreach ( WC()->cart->get_cart() as $item ) {
// Detects if the needed product category is in cart items
if ( has_term($category_needed, 'product_cat', $item['product_id'] ) ) {
$has_cat = true;
break;
}
}
return $has_cat;
}
// Function that display a message if there is not in cart a mandatory product category
function mandatory_category_display_message() {
$category_needed = your_mandatory_category_slug();
// check that cart is not empty (for cart and product category archives)
if( !WC()->cart->is_empty() && ( is_cart() || is_product_category( $category_needed ) ) ){
$category_obj = get_term_by( 'slug', $category_needed, 'product_cat' );
if ( is_wp_error( $category_obj ) ) return;
// Display message when product category is not in cart items
if ( !has_mandatory_category() ) {
$category_name = $category_obj->name;
$category_url = get_term_link( $category_needed, 'product_cat' );
// render a notice to explain why checkout is blocked
wc_add_notice( sprintf( __( '<strong>Reminder:</strong> You have to add in your cart, a product from "%1$s" category, to be allowed to check out. Please return <a href="%2$s"> here to "%1$s" product page</a>', 'your_theme_domain'), $category_name, $category_url ), 'error' );
}
}
}
add_action( 'woocommerce_before_main_content', 'mandatory_category_display_message', 30 ); // for product mandatory category archives pages
add_action( 'woocommerce_check_cart_items', 'mandatory_category_display_message' ); // for cat page
// Function that redirect from checkout to mandatory product category archives pages
function mandatory_category_checkout_redirect() {
// If cart is not empty on checkout page
if( !WC()->cart->is_empty() && is_checkout() ){
$category_needed = your_mandatory_category_slug();
// If missing product category => redirect to the products category page
if ( !has_mandatory_category() )
wp_redirect( get_term_link( $category_needed, 'product_cat' ) );
}
}
add_action('template_redirect', 'mandatory_category_checkout_redirect');
这可以在您的活动子主题(或主题)的function.php文件中,也可以在任何插件文件中。
此代码经过测试且功能齐全。

使用Woocommerce v2.6.12,就像我的Wordpress安装的魅力一样。
我想添加两个强制性产品类别,将来可能会有3个或4个。我尝试过改变:
$category = 'slug1';
到
$category = 'slug1', 'slug2';
和
$category = array('slug1','slug2');
没有成功。有没有办法让这个代码适用于多个slugs?

我已经调整了 LoicTheAztec 的答案以处理 2 个类别。它似乎正在工作。我没有修改文本 has_mandatory_categorytext
函数,.如果您可以按照代码进行操作,则可以自己动手做,但我只关注功能。还有另一个答案 here,但我更喜欢这个答案,而另一个不适合我。
// Function that define the 2 mandatory product categories cat1 & cat2
function your_mandatory_category_slug(){ $category = 'cat1'; return $category; }
function your_mandatory_category_slug2(){ $category = 'cat2'; return $category; }
// Conditional function that returns true if the mandatory product category is in cart
function has_mandatory_category1(){
$category_needed = your_mandatory_category_slug();
$has_cat = false;
foreach ( WC()->cart->get_cart() as $item ) {
if ( has_term($category_needed, 'product_cat', $item['product_id'] ) ) {
$has_cat = true;
break;
}
}
return $has_cat;
}
// Conditional function that returns true if the mandatory product category is in cart
function has_mandatory_category2(){
$category_needed = your_mandatory_category_slug2();
$has_cat = false;
foreach ( WC()->cart->get_cart() as $item ) {
if ( has_term($category_needed, 'product_cat', $item['product_id'] ) ) {
$has_cat = true;
break;
}
}
return $has_cat;
}
// Function that redirect from checkout to mandatory product category archives pages
function mandatory_category_checkout_redirect() {
// If cart is not empty on checkout page
if( !WC()->cart->is_empty() && is_checkout() ){
$category_needed = your_mandatory_category_slug();
$category_needed2 = your_mandatory_category_slug2();
if ( !has_mandatory_category1() )
wp_redirect( get_term_link( $category_needed, 'product_cat' ) );
if ( !has_mandatory_category2() )
wp_redirect( get_term_link( $category_needed2, 'product_cat' ) );
}
}
add_action('template_redirect', 'mandatory_category_checkout_redirect');
