【中文标题】在商店和存档页面中选择变量时如何更改产品图片?【英文标题】:How to change product Image when variables are selected in Shop and Archive Pages? 【发布时间】:2021-12-24 14:31:57 【问题描述】:我使用这个钩子在商店页面上显示变体。但是,选择变量时产品图像不会改变。它适用于单一产品页面。 WordPress 和 php 的新手,我认为 woocommerce 钩子的工作方式类似于“复制和粘贴”。为什么它不适用于商店页面?它如何适用于商店页面?
add_action( 'woocommerce_before_shop_loop', 'show_production_variations_on_shop_page' );
function show_production_variations_on_shop_page()
remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart', 10 );
add_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_single_add_to_cart', 30 );
【问题讨论】:
show_production_variations_on_shop_page() 里面有什么?您也不能混合使用它们传递不同参数的钩子,因此有些适用于档案、类别等,其他适用于购物车,其他适用于单一产品。对于变化,WooCommerce 也使用 JS。使用插件或调试。对于当前示例,没有任何帮助。 感谢@MartinMircev 添加后,它会在商店页面上显示变体选择框、数量字段和添加到购物车按钮。 就像我说的那样,你不能只混合钩子 - woocommerce_template_single_add_to_cart 将执行以下操作 - 根据产品类型加载不同的函数在你的情况下将加载这个 woocommerce_variable_add_to_cart() ,它在其中构建了变体产品表单。 hookr.io/plugins/woocommerce/3.0.6/files/… 。要更新图像,您必须使用 ajax 或加载所有图像并在更改时更新到正确的图像。更新后添加到购物车按钮变量。 非常感谢@MartinMirchev 请问我可以查看哪些模板页面来了解如何为单个产品页面中的可变产品切换图像? 如果你无法调试,你将很难解决它。您可以查看负责在变体选择上更新图像的 js - github.com/woocommerce/woocommerce/blob/trunk/plugins/…。对于模板,您应该使用 content-product.php 及其挂钩来输出您的变体等等 - github.com/woocommerce/woocommerce/blob/trunk/plugins/… 【参考方案1】:首先,您必须将 woocommerce add-to-cart-variation.js
从商店页面中取出,因为无论您在哪里开发,都需要从您的主题或插件中克隆 add-to-cart-variation.js
和 enqueue
。
function add_custom_js()
if( is_shop() )
wp_dequeue_script( 'wc-add-to-cart-variation' );
wp_deregister_script( 'wc-add-to-cart-variation' );
$version = WC_VERSION;
// Register the script
wp_register_script( 'wc-add-to-cart-variation', get_template_directory_uri().'/assets/js/add-to-cart-variation.js', array( 'jquery', 'wp-util', 'jquery-blockui' ), $version );
// Localize the script with new data
$params = array(
'wc_ajax_url' => WC_AJAX::get_endpoint( '%%endpoint%%' ),
'i18n_no_matching_variations_text' => esc_attr__( 'Sorry, no products matched your selection. Please choose a different combination.', 'woocommerce' ),
'i18n_make_a_selection_text' => esc_attr__( 'Please select some product options before adding this product to your cart.', 'woocommerce' ),
'i18n_unavailable_text' => esc_attr__( 'Sorry, this product is unavailable. Please choose a different combination.', 'woocommerce' ),
);
wp_localize_script( 'wc-add-to-cart-variation', 'wc_add_to_cart_variation_params', $params );
// Enqueued script with localized data.
wp_enqueue_script( 'wc-add-to-cart-variation' );
add_action( 'wp_enqueue_scripts', 'add_custom_js', 9999, 1 );
在您正在开发的活动主题或插件中创建一个add-to-cart-variation.js
文件。 (我是主题的enqueueing
)
在下面添加与woocommerce add-to-cart-variation.js
相同的js代码,但我们必须根据需要对其进行修改。

经过测试并且有效。
【讨论】:
谢谢@Bhautik。它对我不起作用。为了快速测试,我测试了 20。将您的add-to-cart-variation.js
复制并粘贴到主题的/js/add-to-cart-variation.js
。将此行从您的函数 /assets/js/add-to-cart-variation.js
更改为 /js/add-to-cart-variation.js
以反映 js 文件的正确目录。在functions.php
中插入函数。没有错误,但它不起作用。
可以分享一下网址吗?
抱歉,应该修复了。
已修复。请检查并告诉我。
