在Woocommerce存档页面中显示所有产品类型的库存可用性 [英] Display the stock availability for all product types in Woocommerce archive pages

问题描述

我在显示产品库存时使用此代码:

I am using this code in showing the stocks of products:

    add_action( 'woocommerce_after_shop_loop_item', 'display_variable_product_stock_quantity', 10 );
function display_variable_product_stock_quantity(){
    wc_get_variable_product_stock_quantity( 'echo_html' );
} 

function show_stock() {
global $product;
if ( $product->stock ) { // if manage stock is enabled 
if ( ! $product->managing_stock() && ! $product->is_in_stock() )
        echo '';
}
if ( number_format($product->stock,0,'','') > 0 ) { // if stock is low
echo '<div class="remainingpc" style="text-align:center;"><font color="red"> ' . number_format($product->stock,0,'','') . ' Pcs Left</font></div>';
} 
else {
echo '<div class="remaining" style="text-align:center;"><font color="red">Out of Stock</font></div>'; 
}
}

add_action('woocommerce_after_shop_loop_item','show_stock', 10);

如果产品是变量，我将使用此答案代码显示库存状况:
获取Woocommerce中可变产品的所有变体的总库存量

And if the product is a variable I use this answer code to display the stock availability:
Get the total stock of all variations from a variable product In Woocommerce

如何将这些代码合并到单个条件函数中?

How can I merge this codes in a single conditional function?

例如.如果产品是简单产品，则不会显示其他变量产品代码.

For example. if the products is a simple product, the other code for variable product will not display.

推荐答案

以下内容将显示woocommerce存档产品页面中所有产品类型的库存状况，如商店.

The following will handle the display of the stock availability for all product types in woocommerce archive product pages as shop.

要处理除变量以外的其他产品类型的库存可用性显示，可以使用专用功能wc_get_stock_html()代替，这将简化代码.

To handle the stock availability display for other product types than variable, you can use the dedicated function wc_get_stock_html() instead, which will simplify the code.

add_action( 'woocommerce_after_shop_loop_item', 'wc_loop_get_product_stock_availability_text', 10 );
function wc_loop_get_product_stock_availability_text() {
    global $wpdb, $product;

    // For variable products
    if( $product->is_type('variable') ) {

        // Get the stock quantity sum of all product variations (children)
        $stock_quantity = $wpdb->get_var("
            SELECT SUM(pm.meta_value) FROM {$wpdb->prefix}posts as p
            JOIN {$wpdb->prefix}postmeta as pm ON p.ID = pm.post_id
            WHERE p.post_type = 'product_variation'
            AND p.post_status = 'publish' AND p.post_parent = '".get_the_id()."'
            AND pm.meta_key = '_stock' AND pm.meta_value IS NOT NULL
        ");

        if ( $stock_quantity > 0 ) {
            echo '<p class="stock in-stock">'. sprintf( __("%s in stock", "woocommerce"), $stock_quantity ).'</p>';
        } else {
            if ( is_numeric($stock_quantity) )
                echo '<p class="stock out-of-stock">' . __("Out of stock", "woocommerce") . '</p>';
            else
                return;
        }
    }
    // Other products types
    else {
        echo wc_get_stock_html( $product );
    }
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试，可以正常工作.

Code goes in function.php file of your active child theme (or active theme). Tested and works.
