我必须检查我的两个必选产品类别之一是否在购物车中。
我已根据此答案自定义了代码:
Allow checkout only when a product of a mandatory category is in cart
但是使用我的自定义代码,它总是只检查其中之一,并且我收到一些错误。我的代码无法运行。
如何使其适用于 2 个产品类别而不是一个产品类别?
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 = 'cxsuite-download-option';
return $category;
}
function your_mandatory_category_slug_h(){
// DEFINE HERE the SLUG of the needed product category
$category_h = 'cxsuite-hosted-option';
return $category_h;
}
// Conditional function that returns true if the mandatory product category is in cart
function has_mandatory_category(){
$category_needed = your_mandatory_category_slug();
$category_needed_h = your_mandatory_category_slug_h();
$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'] ) ) {
$has_cat = true;
break;
}
elseif ( has_term($category_needed_h, '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();
$category_needed_h = your_mandatory_category_slug_h();
// check that cart is not empty (for cart and product category archives)
if( !WC()->cart->is_empty() && ( is_cart() || is_product_category( $category_needed ) || is_product_category( $category_needed_h ) ) ){
$category_needed_single=null;
if( $category_needed=='cxsuite-download-option' ){
$category_needed_single='cxsuite-download-option';
}{
$category_needed_single=$category_needed_h;
}
$category_obj = get_term_by( 'slug', $category_needed_single, '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( $category_needed_single, 'product_cat' );
// render a notice to explain why checkout is blocked
wc_add_notice( sprintf( __( '<strong>Reminder:</strong> You have chosen Addon that can only be purchased together with a %1$s. Please add a %1$s (full or trial) before checking out. Please return <a href="%2$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();
$category_needed_h = your_mandatory_category_slug_h();
$category_needed_single=null;
if(is_product_category( $category_needed )){
$category_needed_single=$category_needed;
}else{
$category_needed_single=$category_needed_h;
}
// If missing product category => redirect to the products category page
if ( !has_mandatory_category() )
wp_redirect( get_term_link( $category_needed_single, 'product_cat' ) );
}
}
add_action('template_redirect', 'mandatory_category_checkout_redirect');

您只能部分使用从我的答案中获取的代码,对于 2 个或更多类别,通过以下方式使用一系列产品类别:
// Function that define the mandatory product category
function your_mandatory_category_slug(){
// DEFINE HERE the 2 SLUGs of the needed product categories
$categories = array('cxsuite-download-option','cxsuite-hosted-option');
return $categories;
}
// Conditional function that returns true if the mandatory products categories are in cart
function has_mandatory_category(){
$categories_needed = your_mandatory_category_slug();
$has_cat = false;
// Iterrating each item in cart and detecting…
foreach ( WC()->cart->get_cart() as $item ) {
// iterating both categories
foreach ( $categories_needed as $category_needed ) {
// Detects if one of the needed product categories is in cart items
if ( has_term($category_needed, 'product_cat', $item['product_id'] ) )
$has_cat = true;
}
if($has_cat)
break;
}
return $has_cat;
}
// Function that display a message if there is not in cart a mandatory product category
function mandatory_category_display_message() {
$categories_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( $categories_needed[0] ) || is_product_category( $categories_needed[1] ) ) ){
$category_name = array();
$category_url = array();
// iterating both categories
foreach($categories_needed as $key => $category_needed){
$category_obj = get_term_by( 'slug', $category_needed, 'product_cat' );
if ( is_wp_error( $category_obj ) )
return;
$category_name[$key] = $category_obj->name;
$category_url[$key] = get_term_link( $category_needed, 'product_cat' );
}
// Display message when one of the product categories is not in cart items
if ( !has_mandatory_category() ) {
// render a notice to explain why checkout is blocked
wc_add_notice( sprintf( __( '<strong>Reminder:</strong> You have to add in your cart, a product from "%1$s" or from "%3$s" category, to be allowed to check out. Please return <a href="%2$s"> here to "%1$s"</a> or <a href="%4$s"> here to "%3$s"</a> product pages', 'your_theme_domain'), $category_name[0], $category_url[0], $category_name[1], $category_url[1] ), '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 cart page
但是您必须在重定向的 2 个产品类别之一中选择最后一个功能...
// 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() ){
$categories_needed = your_mandatory_category_slug();
// If missing product category => redirect to the products category page
if ( !has_mandatory_category() )
wp_redirect( get_term_link( $categories_needed[0], 'product_cat' ) ); // or $categories_needed[1]
}
}
add_action('template_redirect', 'mandatory_category_checkout_redirect');
这会出现在您的事件子主题(或主题)的 function.php 文件中,或者也出现在任何插件文件中。
此代码基于此功能答案:
Allow checkout only when a product of a mandatory category is in cart
它未经测试,但应该可以工作......
