我在一个帖子上使用php进行woocommerce,并希望根据他们的库存水平显示/隐藏某个类别的产品。目前使用get_term()和产品计数包括"缺货"产品。使用get_terms()和同一类别的产品计数仅计入"库存"产品。如何编写if else条件语句以使用特定产品类别的get_terms计数?
这是我到目前为止的代码("如果"属于此类别中的产品是"缺货"。想要"如果" ;只有当此类别的产品是"库存")时才是真实的:
<?php
$term = get_term(373, 'product_cat' );
$category = $term->name;
$theCount = $term->count;
if ( ( $category = 'Outlet Other' ) && ( $theCount > 0 ) ){
echo '[product_category category="outlet-other" per_page="100" orderby="menu_order" order="asc"]';}
else {
echo 'There are currently no products in this category. Please check back soon!';}
?>
以下是我在页面上用于测试目的的其他代码,它使用get_terms()等于&#34;库存&#34;来显示此类别的产品计数。量:
<?php
$terms = get_terms( 'product_cat' );
foreach( $terms as $term ){
echo 'Product Category: ' . $term->name . ' - Count: ' . $term->count . "\r\n";}
?>

<?php
$term = get_term(373, 'product_cat' );
$category = $term->name;
$termsother = get_terms( 'product_cat' );
foreach( $termsother as $termsnew ) {
if (($termsnew->count > 0) && ($termsnew->name == $category)) {
echo '[product_category category="' . $termsnew->slug . '" per_page="100" orderby="menu_order" order="asc"]';
}
elseif (($termsnew->count == 0) && ($termsnew->name == $category)) {
echo 'There are currently no products in this category. Please check back soon!';
}
else {
//echo 'If and ElseIf are false!';
}
}
?>

在if语句之前,使用您的测试代码检查该类别中是否有库存中的产品,并为您的if语句添加其他条件。请参阅下面的代码。
<?php
$term = get_term(373, 'product_cat' );
$category = $term->name;
$theCount = $term->count;
$terms = get_terms( 'product_cat' );
$category_has_in_stock_items = false;
foreach( $terms as $term ) {
if ($term->count > 0) {
category_has_in_stock_items = true;
break;
}
}
if (($category = 'Outlet Other') && ($theCount > 0) && $category_has_in_stock_items){
echo '[product_category category="outlet-other" per_page="100" orderby="menu_order" order="asc"]';}
else {
echo 'There are currently no products in this category. Please check back soon!';}
?>

我不知道它是否完全指向发问者提出的问题,但是我在WP REST API中遇到get_terms
时遇到了类似的问题。经过一个小时的调试,我发现WooCommerce仅在is_admin() || is_ajax()
时才更改条款计数:
解决方案:在__return_true
函数调用之前添加get_terms
过滤器,以在WP REST API中模拟AJAX请求:
add_filter('wp_doing_ajax', '__return_true');
$terms = get_terms([
// [...]
'pad_counts' => 1 // This is necessery if you want to correct parent categories count, too
]);
remove_filter('wp_doing_ajax', '__return_true');
