Question

我创建了一个函数discount_foil_seal_items()，它使用钩子woocommerce_before_calculate_totals在购物车中应用价格变化。它会更新购物车总数，但是当我结账时运费计算超时（即永久旋转图标）。我无法找到与此特定问题相关的任何帖子。

我尝试评论函数的各个部分以查看导致它的原因，并且似乎如果我在此函数中运行foreach中的任何一个，它就会超时。是否与在foreach中嵌套if语句或switch语句有关？

//apply discounts to foil and seal product categories
add_action( 'woocommerce_before_calculate_totals', 'discount_foil_seal_items', 10, 1 );
function discount_foil_seal_items( $cart_object ) {

// Iterating through each item in cart
foreach ( $cart_object->get_cart() as $item_values ) {

    // Get cart item data
    $item_id = $item_values['data']->id; // Product ID
    $item_qty = $item_values['quantity']; // Item quantity

    // Get the object
    $product = new WC_Product( $item_id );
    $prod_cat = wp_get_post_terms($product->id,'product_cat',array('fields'=>'slugs'));

    //tally totals
    if (in_array('seal-stickers', $prod_cat)){
        $seal_prod_tally += $item_qty;
    }else if(in_array('foil-badges', $prod_cat)){
        $foil_prod_tally += $item_qty;
    }
}

 foreach ( $cart_object->get_cart() as $item_values ) {

    //Get cart item data
    $item_id = $item_values['data']->id; // Product ID
    $item_qty = $item_values['quantity']; // Item quantity

    // Get the object
    $product = new WC_Product( $item_id );
    $prod_cat2 = wp_get_post_terms($product->id,'product_cat',array('fields'=>'slugs'));        

    //apply discount to each item within category
    if (in_array('seal-stickers',$prod_cat2)){
        switch ($seal_prod_tally){
            case 25000:
                $item_values['data']->set_price(1327.01/20000);
                echo 'case 25000 seal has run <br>';
                break;
            case 30000:
                $item_values['data']->set_price(1578.65/30000);
                break;
            case 50000:
                $item_values['data']->set_price(2126.76/50000);
                break;
            case 60000:
                $item_values['data']->set_price(2405.98/60000);
                break;
        }        
    }else if (in_array( 'foil-badges',$prod_cat2)){
        switch ($foil_prod_tally){
            case 25000:
                $item_values['data']->set_price(5872.63/25000);
                break;
            case 50000:
                $item_values['data']->set_price(10815.47/50000);
                break;
        }            
    } 

 }

}

此外，我已经注释掉了foreach并插入了一个简化的foreach，如下所示，运行良好：

//this foreach doesn't timeout
    foreach ( $cart_object->get_cart() as $item_values ){        
        $item_values['data']->set_price(1327.01/20000);
    }

此网站上的其他产品结帐时没有超时错误。

非常感谢任何导致超时的帮助！

我尝试重写代码替换switch语句，if else if if if无效。然后我尝试将这些函数拆分成两个独立的函数，看看是否做了什么也没有修复超时。这里的代码分为两个不同的函数：

//apply discounts to foil and seal product categories
add_action( 'woocommerce_before_calculate_totals', 'cart_count_foil_seal_items',10,1);

function cart_count_foil_seal_items( $cart_object ) {
    echo 'discount_foil_seal_items() has run <br>';
    $seal_prod_tally = 0;
    $foil_prod_tally = 0;
// Iterating through each item in cart
foreach ( $cart_object->get_cart() as $item_values ) {
    //  Get cart item data
    $item_id = $item_values['data']->get_id(); // Product ID
    $item_qty = $item_values['quantity']; // Item quantity

    // Getting the object
    $product = new WC_Product( $item_id );
    $prod_cat = wp_get_post_terms($product->get_id(),'product_cat',array('fields'=>'slugs'));

    //tally total
    if (in_array('seal-stickers', $prod_cat)){
        $seal_prod_tally += $item_qty;
    }else if(in_array('foil-badges', $prod_cat)){
        $foil_prod_tally += $item_qty;
    }
}

 return array($seal_prod_tally,$foil_prod_tally);
}

//apply discounts to foil and seal product categories
add_action( 'woocommerce_before_calculate_totals', 'discount_foil_seal_items',12);

function discount_foil_seal_items( $cart_object ) {
echo 'discount_foil_seal_items() has run <br>';

list($seal_prod_tally, $foil_prod_tally) = cart_count_foil_seal_items($cart_object);

 foreach ( $cart_object->get_cart() as $item_values ) {

    //Get cart item data
    $item_id = $item_values['data']->get_id(); // Product ID
    $item_qty = $item_values['quantity']; // Item quantity

    // Getting the object
    $product = new WC_Product( $item_id );
    $prod_cat2 = wp_get_post_terms($product->get_id(),'product_cat',array('fields'=>'slugs'));        

    //apply discount to each item within category

      if (in_array('seal-stickers',$prod_cat2)){

        switch ($seal_prod_tally){
            case 25000:
                $item_values['data']->set_price(1327.01/20000);
                break;
            case 30000:
                $item_values['data']->set_price(1578.65/30000);
                break;
            case 50000:
                $item_values['data']->set_price(2126.76/50000);
                break;
            case 60000:
                $item_values['data']->set_price(2405.98/60000);
                break;
            default:
                break;
        }        
    }else if (in_array( 'foil-badges',$prod_cat2)){
        switch ($foil_prod_tally){
            case 25000:
                $item_values['data']->set_price(5872.63/25000);
                break;
            case 50000:
                $item_values['data']->set_price(10815.47/50000);
                break;
            default:
                break;
        }            
    }      
 }

}

Answer 1

我发现问题是我用于调试目的的echo语句。我删除了它，它工作。我没有意识到回声声明会导致这样的超时但是很有必要知道：

我删除了这一行： echo 'discount_foil_seal_items() has run <br>';

在两个功能中都有效。
