根据产品类别拒绝在WooCommerce中结账的特定购物车项目

原学程将引见依据产物类型谢绝在WooCo妹妹erce中结账的特定买物车项目标处置办法,这篇学程是从其余处所瞅到的,而后减了1些海外法式员的疑问与解问,愿望能对于您有所赞助,佳了,上面开端进修吧。

根据产品类别拒绝在WooCommerce中结账的特定购物车项目 教程 第1张

成绩描写

鉴于Allow checkout only when a product of a mandatory category is in cart,我测验考试制造本身的代码样原,以出现告诉并避免结账,假如买物车
仅包括特定类型的产物。它在预防以及毛病告诉圆里起感化,然则在添减其余产物时,它依然谢绝结账。

/**
 * Renders a notice and prevents checkout if the cart
 * only contains products in a specific category
 */
//add_action( 'wooco妹妹erce_check_cart_items', 'brown_wc_prevent_checkout_for_category' );

function brown_wc_prevent_checkout_for_category() {

 // set the slug of the category for which we disallow checkout
 $categories = array('drinks','extra-accompaniments');

 foreach ($categories as $category => $value) {
  // 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;
  }

  // check if this category is the only thing in the cart
  if ( brown_wc_is_category_alone_in_cart( $category ) ) {

// render a notice to explain why checkout is blocked
wc_add_notice( sprintf( 'Please choose atleast one bento.', $category ), 'error' );
  }
 }

}

/**
 * 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 brown_wc_is_category_alone_in_cart( $category ) {

 //When the cart is empty, remove warning message that I have set for when the snippet takes effect
 if (!WC()->cart->is_empty()) {
  // All the code
  // 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;

 } else {

  return false;//  Assume you'd want false here, since the cart is empty

 }

}

推举谜底

您的代码中有1些毛病会招致它没法胜利任务。您的代码以及请求与我的previous answer完整分歧。

您必需为告诉树立所需的按钮URL以及文原,如"便利"产物类型链交以及按钮称号。

代码以下:

// Conditional function that check if the non mandatory product categories are in all cart items
function has_not_mandatory_category(){
 // DEFINE HERE the your non mandatory product categories (Ids, slugs or names)
 $categories = array('drinks','extra-accompaniments');

 // Iterrating each item in cart and detecting…
 foreach ( WC()->cart->get_cart() as $cart_item ) {
  $product_id = $cart_item['product_id']; // <== This is the right way (working for product variations too)
  if ( ! has_term( $categories, 'product_cat', $product_id ) )
return false;
 }
 return true;
}

// Display a message and prevent checkout if the non mandatory product categories are not in all cart items
add_action( 'wooco妹妹erce_check_cart_items', 'prevent_checkout_display_notice' ); // for cart and checkout
function prevent_checkout_display_notice() {
 // DEFINE HERE the return button URL and title
 $button_url = '#';
 $button_title = 'Go there';

 // Display message if the non mandatory product categories are not in all cart items
 if ( has_not_mandatory_category() )
  wc_add_notice(
sprintf( __( 'Please choose at least one bento. <a class="button" href="%s">%s</a>', 'your_theme_domain'),
 $button_url,
 $button_title
), 'error'
  );
}

已尝试以及任务的…

您应当履行相反的…操纵,而没有是针对于非强迫性产物类型
