Question

在下面的代码中，它有一个foreach，这是改变它的最佳方式，因此它允许我检查$instock。我尝试在if中使用foreach语句，但它没有看到endforeach

循环：

$args = array( 'posts_per_page' => 4, 'post_type' => 'product','meta_key' => '_featured','meta_value' => 'yes','orderby' =>'rand','order' => 'DESC');

$myposts = get_posts( $args );

foreach ( $myposts as $post ) : 
    setup_postdata( $post );
    $product = new WC_Product( get_the_ID() );
    $price = $product->price;
    $instock = $product->is_in_stock();
?>
    <div class="col-sm-6 col-md-3">
        <div class="thumbnail Product_Box">
            <a href="<?php the_permalink()?>"><?php the_post_thumbnail();?></a>
            <div class="caption">
                <h4><?php the_title()?><br />
                    <span class="text-color">$<?php echo $price; ?></span>
                </h4>
            </div>
        </div>
    </div>

<?php endforeach;
wp_reset_postdata();?>

如果产品没有库存，清洁的解决方案就是跳过产品。因此，您将获得以下内容。

$args = array( 'posts_per_page' => 4, 'post_type' => 'product','meta_key' => '_featured','meta_value' => 'yes','orderby' =>'rand','order' => 'DESC');

$myposts = get_posts( $args );

foreach ( $myposts as $post ) : 
    setup_postdata( $post );
    $product = new WC_Product( get_the_ID() );
    $price = $product->price;
    $instock = $product->is_in_stock();

    if (!$instock) {
        continue;
    }
?>
    <div class="col-sm-6 col-md-3">
        <div class="thumbnail Product_Box">
            <a href="<?php the_permalink()?>"><?php the_post_thumbnail();?></a>
            <div class="caption">
                <h4><?php the_title()?><br />
                    <span class="text-color">$<?php echo $price; ?></span>
                </h4>
            </div>
        </div>
    </div>

<?php endforeach;
wp_reset_postdata();?>

更改循环以包含$ var
