[英]Replace “add to cart” with custom quantity input fields in WooCommerce
I am using WooCommerce with Storefront theme to build an eCommerce website that will be used on smartphones mostly.我正在使用带有店面主题的 WooCommerce 来构建一个主要用于智能手机的电子商务网站。 So I am trying to reduce the number of clicks and buttons to make it as simple as possible.
所以我试图减少点击次数和按钮次数,使其尽可能简单。
I would like to replace "add to cart" button with a quantity selector :我想用数量选择器替换“添加到购物车”按钮:
I found a way to add a quantity selector next to "add to cart" button (eg with plugin WooCommerce Advanced Product Quantities) but I would like to get rid of "add to cart" button.我找到了一种在“添加到购物车”按钮旁边添加数量选择器的方法(例如使用插件 WooCommerce 高级产品数量),但我想摆脱“添加到购物车”按钮。 So, when a customer click on "+", it should add 1 element to the cart and the number should display the quantity in the cart.
因此,当客户点击“+”时,它应该向购物车添加 1 个元素,并且数字应该显示购物车中的数量。
Also (no idea if this is possible...), I'd like an animation to notify the customer that the product was well added to the cart.另外(不知道这是否可行......),我想要一个动画来通知客户该产品已很好地添加到购物车中。 For instance, show a "+1" for a few seconds near the cart icon,
例如,在购物车图标附近显示“+1”几秒钟,
here you go it's going to be long one :你去吧,它会很长:
First Let's Remove the Add To Cart Button:首先让我们删除添加到购物车按钮:
// Remove Add To cart Button
remove_action('woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart', 10);
Now Lets Create our Input and add it to shop page现在让我们创建我们的输入并将其添加到商店页面
// Add our Quanity Input
add_action('woocommerce_after_shop_loop_item', 'QTY');
function QTY()
{
global $product;
?>
<div class="shopAddToCart">
<button value="-" class="minus" >-</button>
<input type="text"
disabled="disabled"
size="2"
value="<?php echo (Check_if_product_in_cart($product->get_id())) ? Check_if_product_in_cart($product->get_id())['QTY'] : 0;
?>"
id="count"
data-product-id= "<?php echo $product->get_id() ?>"
data-in-cart="<?php echo (Check_if_product_in_cart($product->get_id())) ? Check_if_product_in_cart($product->get_id())['in_cart'] : 0;
?>"
data-in-cart-qty="<?php echo (Check_if_product_in_cart($product->get_id())) ? Check_if_product_in_cart($product->get_id())['QTY'] : 0;
?>"
class="quantity qty"
max_value = <?php echo ($product->get_max_purchase_quantity() == -1) ? 1000 : $product->get_max_purchase_quantity(); ?>
min_value = <?php echo $product->get_min_purchase_quantity(); ?>
>
<button type="button" value="+" class="plus" >+</button>
</div>
<?php
}
we need to have function to check if the products is already in cart or not so can modify the quantity:我们需要有功能来检查产品是否已经在购物车中,以便可以修改数量:
//Check if Product in Cart Already
function Check_if_product_in_cart($product_ids)
{
foreach (WC()->cart->get_cart() as $cart_item):
$items_id = $cart_item['product_id'];
$QTY = $cart_item['quantity'];
// for a unique product ID (integer or string value)
if ($product_ids == $items_id):
return ['in_cart' => true, 'QTY' => $QTY];
endif;
endforeach;
}
we need to add custom event in order to reduce the quantity:我们需要添加自定义事件以减少数量:
//Add Event Handler To update QTY
add_action('wc_ajax_update_qty', 'update_qty');
function update_qty()
{
ob_start();
$product_id = absint($_POST['product_id']);
$product = wc_get_product($product_id);
$quantity = $_POST['quantity'];
foreach (WC()->cart->get_cart() as $cart_item_key => $cart_item):
if ($cart_item['product_id'] == $product_id) {
WC()->cart->set_quantity($cart_item_key, $quantity, true);
}
endforeach;
wp_send_json('done');
}
Finally We need Javascript to handle the event actions :最后我们需要 Javascript 来处理事件动作:
jQuery(document).ready(function ($) {
"use strict";
// Add Event Listner on the Plush button
$('.plus').click(function () {
if (parseInt($(this).prev().val()) < parseInt($(this).prev().attr('max_value'))) {
$(this).prev().val(+$(this).prev().val() + 1);
var currentqty = parseInt($(this).prev().attr('data-in-cart-qty')) + 1;
var id = $(this).prev().attr('data-product-id');
var data = {
product_id: id,
quantity: 1
};
$(this).prev().attr('data-in-cart-qty', currentqty);
$(this).parent().addClass('loading');
$.post(wc_add_to_cart_params.wc_ajax_url.toString().replace('%%endpoint%%', 'add_to_cart'), data, function (response) {
if (!response) {
return;
}
if (response) {
var url = woocommerce_params.wc_ajax_url;
url = url.replace("%%endpoint%%", "get_refreshed_fragments");
$.post(url, function (data, status) {
$(".woocommerce.widget_shopping_cart").html(data.fragments["div.widget_shopping_cart_content"]);
if (data.fragments) {
jQuery.each(data.fragments, function (key, value) {
jQuery(key).replaceWith(value);
});
}
jQuery("body").trigger("wc_fragments_refreshed");
});
$('.plus').parent().removeClass('loading');
}
});
}
});
$('.minus').click(function () {
$(this).next().val(+$(this).next().val() - 1);
var currentqty = parseInt($(this).next().val());
var id = $(this).next().attr('data-product-id');
var data = {
product_id: id,
quantity: currentqty
};
$(this).parent().addClass('loading');
$.post(wc_add_to_cart_params.wc_ajax_url.toString().replace('%%endpoint%%', 'update_qty'), data, function (response) {
if (!response) {
return;
}
if (response) {
var url = woocommerce_params.wc_ajax_url;
url = url.replace("%%endpoint%%", "get_refreshed_fragments");
$.post(url, function (data, status) {
$(".woocommerce.widget_shopping_cart").html(data.fragments["div.widget_shopping_cart_content"]);
if (data.fragments) {
jQuery.each(data.fragments, function (key, value) {
jQuery(key).replaceWith(value);
});
}
jQuery("body").trigger("wc_fragments_refreshed");
});
$('.plus').parent().removeClass('loading');
}
});
});
});
Note: This code is tested and working you can check it at注意:此代码已经过测试并且可以正常工作,您可以在
