我一直在到处寻找,但似乎找不到一个非常简单问题的解决方案。我有一家 Woocommerce 商店,如果缺货,我想向用户显示变体旁边的“缺货”消息。我不希望它变灰,我希望用户能够选择它,以便他们可以根据需要查看价格。我在网上找到的大多数片段仅在产品有一种变体时才有效,但我需要它至少适用于两种变体。我的网站销售移动设备,例如:
如果用户选择存储为 64GB,则颜色列表会更新,显示 64GB 中哪些颜色缺货。如果所有颜色都缺货,那么 64GB 旁边也会显示“缺货”。
如果先选择颜色,然后存储 - 颜色列表会更新为缺货的颜色。
有人可以帮我吗?试图让这个工作变得疯狂。下面的代码可以按照我上面提到的确切方式将缺货产品变灰(它适用于多种产品),但我不知道如何针对上面提到的用例修改它。
add_filter( 'woocommerce_variation_is_active', 'grey_out_variations_when_out_of_stock', 10, 2 );
function grey_out_variations_when_out_of_stock( $grey_out, $variation ){
if ( ! $variation->is_in_stock() ){
return false;
}else{
print_r($option_class);
return $term_name . ' - Out of Stock';;
}
}
仅当选择了除其中一个属性之外的所有属性时(而不是之前),您才能检查产品变体的可用性。
所有必要的数据都显示在产品页面上,因此您可以使用 jQuery 脚本来处理它。在变体表单中,有
data-product_variations
属性,其中包含一个数组,其中包含产品变体的所有详细信息(变体 ID、库存状态、它使用的属性等)。然后您可以在所选属性和可能的产品变体之间进行比较。
想法是这样的:
woocommerce_update_variation_values
事件,该事件在通过 Ajax 更新选项后触发(否则更改将被覆盖)
以下代码适用于 2 个或更多属性(下拉列表) 可变产品页面。
// add the text "Out of stock" to each option of the last unselected attribute dropdown
add_action( 'wp_footer', 'add_out_of_stock_text_to_the_last_unselected_attribute_dropdown' );
function add_out_of_stock_text_to_the_last_unselected_attribute_dropdown() {
?>
<script type="text/javascript">
// initializes a global variable that will contain the attribute values to be updated ("Out of stock")
let globalAttributesToUpdate;
jQuery(function($){
// check if only one attribute is missing to be selected
function isLastAttribute(){
// if there is only one dropdown it returns false
if ( $('form.variations_form select').length == 1 ) {
return false;

// counts all selected attributes (excluding "Choose an option")
let count = 0;
$('form.variations_form select').each(function(){
if ( $(this).find(':selected').val() ) {

globalAttributesToUpdate = [];

let attrToSet; // contains the slug of the attribute not yet selected

}
});

});
// inserts the text "Out of stock" after updating the variations
// based on the "globalAttributesToUpdate" global variable
$('body').on('woocommerce_update_variation_values', function(){

代码已经过测试并且可以工作。将其添加到您活动主题的functions.php中。
