如何在结帐时设置某个类别的最小重量要求的购买限额？ [英] How to set a purchase limit at checkout with a minimum weight requirement for a certain category?

问题描述

我尝试在结帐前设置购买限额，即：

• formaggi类别的最低重量要求'

这家商店有8个类别的产品，但目的是仅检查1个类别。

我正在使用此代码段，但不适用于该类别，
都不符合最低体重要求。

  / * PESO MINIMO CATEGORIA FORMAGGI 750GR-RAFFO 14mar2020 * / 
 add_action（'woocommerce_check_cart_items'，'cldws_set_weight_requirements'）; 
函数cldws_set_weight_requirements（）{
 //仅在购物车或结帐页面中运行
 if（is_cart（）|| is_checkout（）|| is_product（）&& has_term（'formaggi '，'product_cart'））{
全球$ woocommerce; 
 
 //设置结帐前的最小重量
 $ minimum_weight = 0.750; 
 
 //获取购物车中每个类别的内容总重量
 $ cart_contents_weight = WC（）-> cart-> cart_contents_weight; 
 
 //比较值并添加错误是购物车的总重量
 if（$ cart_contents_weight< $ minimum_weight）{
 //显示错误消息
 wc_add_notice（ sprintf（' Per i Formaggièrichiesto unacquisto minimo di％s gr。< / strong>'
。'< br /> Peso dei Formaggi nel carrello：％s gr'，
 $ minimum_weight * 1000，
 $ cart_contents_weight * 1000，
 get_option（'woocommerce_weight_unit'），
 get_permalink（wc_get_page_id（'shop'））
），'错误' ）; 
} 
} 
}

有人知道我在做什么错或哪里出错了吗？

解决方案

您的代码中有一些错误。

以下代码检查 formaggi类别的最小重量要求，并在代码行之间添加了解释并进行了注释

  function cldws_set_weight_requirements（）{
 //仅在购物车上并检出页面
 if（！（is_cart（）|| is_checkout（）））返回； 
 
 / *设置* / 
 
 //最小权重
 $ minimum_weight = 20; // 20千克
 
 //设置术语（类别）
 $ term =‘formaggi’； 
 
 / *结束设置* / 
 
 //设置变量
 $ found = false; 
 
 //总重量
 $ total_weight = 0; 
 
 //遍历购物车项目
 foreach（WC（）-> cart-> get_cart（）as $ cart_item_key => $ cart_item）{
 //产品id 
 $ product_id = $ cart_item ['product_id']; 
 
 //数量
 $ product_quantity = $ cart_item [‘quantity’]; 
 
 //获得体重
 $ product_weight = $ cart_item [’data’]-> get_weight（）; 
 
 //不为空&具有特定类别
 if（！empty（$ product_weight）&& has_term（$ term，'product_cat'，$ product_id））{
 //购物车包含特定类别的产品
 $ found = true; 
 
 //计算
 $ total_weight + = $ product_quantity * $ product_weight; 
} 
} 
 
 //如果总重量小于最小重量，并且购物车中有特定类别的物品
 if（$ total_weight< ; $ minimum_weight&& $ found）{
 //显示动态错误警告
 wc_add_notice（sprintf（
'％s'类别的最小权重为％s，您当前具有％s'，
 $ term，
 wc_format_weight（$ minimum_weight），
 wc_format_weight（$ total_weight）
），'error'）; 
 
 //删除继续按钮，直到满足条件为止
 remove_action（'woocommerce_proceed_to_checkout'，'woocommerce_button_proceed_to_checkout'，20）; 
} 
} 
 add_action（‘woocommerce_check_cart_items’，’cldws_set_weight_requirements’）； 
  

I try to set a purchase limit before check out, namely:

• A minimum weight requirement for the category 'formaggi'

The shop has 8 categories of products, however, the intention is to only check on 1 category.

I'm using this snippet but it doesn't work with the category, neither for the minimum weight requirement.

/*PESO MINIMO CATEGORIA FORMAGGI 750GR - RAFFO 14mar2020*/
add_action( 'woocommerce_check_cart_items', 'cldws_set_weight_requirements' );
function cldws_set_weight_requirements() {
    // Only run in the Cart or Checkout pages
    if( is_cart() || is_checkout() || is_product () && has_term( ‘formaggi’, ‘product_cart’ )) {
        global $woocommerce;

        // Set the minimum weight before checking out
        $minimum_weight = 0.750;

        // Get the Cart's content total weight per categoria
        $cart_contents_weight = WC()->cart->cart_contents_weight;

        // Compare values and add an error is Cart's total weight
        if( $cart_contents_weight < $minimum_weight  ) {
            // Display our error message
            wc_add_notice( sprintf('<strong>Per i Formaggi è richiesto un acquisto minimo di %s gr.</strong>'
            . '<br />Peso dei Formaggi nel carrello: %s gr',
            $minimum_weight*1000,
            $cart_contents_weight*1000,
            get_option( 'woocommerce_weight_unit' ),
            get_permalink( wc_get_page_id( 'shop' ) )
            ), 'error' );
        }
    }
}

Someone who knows what I am doing wrong or where it is going wrong?

解决方案

There are some mistakes in your code.

The following code checks for A minimum weight requirement for the category 'formaggi', comment with explanation added between the code lines

function cldws_set_weight_requirements() {
    // Only on cart and check out pages
    if( ! ( is_cart() || is_checkout() ) ) return;

    /* SETTINGS */

    // The minimum weight
    $minimum_weight = 20; // 20 kg

    // Set term (category)
    $term = 'formaggi';

    /* END SETTINGS */

    // Set variable
    $found = false;

    // Total weight
    $total_weight = 0;

    // Loop through cart items        
    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {        
        // Product id
        $product_id = $cart_item['product_id'];

        // Quantity
        $product_quantity = $cart_item['quantity'];

        // Get weight
        $product_weight = $cart_item['data']->get_weight();

        // NOT empty & has certain category
        if ( ! empty( $product_weight ) && has_term( $term, 'product_cat', $product_id ) ) {
            // The shopping cart contains a product of the specific category
            $found = true;

            // Calculate
            $total_weight += $product_quantity * $product_weight;
        }
    }

    // If the total weight is less than the minimum and there is a item in the cart from a specific category
    if( $total_weight < $minimum_weight && $found ) {
        // Displays a dynamic error warning
        wc_add_notice( sprintf(
            'The minimum weight for the "%s" category is %s, you currently have %s',
            $term,
            wc_format_weight($minimum_weight),
            wc_format_weight($total_weight)
        ), 'error' );

        // Removing the proceed button, until the condition is met
        remove_action( 'woocommerce_proceed_to_checkout','woocommerce_button_proceed_to_checkout', 20);
    }
}
add_action( 'woocommerce_check_cart_items', 'cldws_set_weight_requirements' );
