Woocommerce get_term() 计数和 get_terms() 计数不同

Question

I'm using php in woocommerce on a post and would like to show/hide products in a category based upon their stock level. Currently using get_term() and the product count includes "out-of-stock" products. Using get_terms() and the product count for that same category counts only "in-stock" products. How do I write my if else condition statement to use the get_terms count of a specific product category?

Here is the code I have so far ("if" is true when products in this category are "out-of-stock". Would like "if" to be true only when products in this category are "in-stock"):

<?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!';}
?>

Here is other code I have on the page for testing purposes that shows the product count for this category using get_terms() equal to "in-stock" quantity:

<?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!';
        }
    }
?>

Prior to the if statement, use your test code to check if there are products in the category that are in stock and add an additional condition to your if statement. See code below.

<?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!';}
?>

I don't know if it refers exactly to the question asked by the questioner, but I had similar problems with get_terms in WP REST API. After debugging an hour I found that WooCommerce is changing the terms count only if is_admin() || is_ajax()is_admin() || is_ajax() :

https://github.com/woocommerce/woocommerce/blob/51912c659db971dcc1bf4a9a31a33777904ec627/includes/wc-term-functions.php#L530-L533

Solution: Add a __return_true filter before your get_terms function call to simulate an AJAX request in WP REST API:

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');
