Question

我有一个jQuery脚本，可以成功地从本地存储中检索数据，然后返回到PHP函数（在子主题中）。在此功能中，我想使用if / else块，以便在打开时更改所有商店页面和链接的产品页面上的所有按钮。取决于从jQuery脚本获得的结果。

共有3个选项：默认的“检查覆盖率”，标准的“添加到购物车”，最后是“注册您的兴趣”

我有3个类别，并且想排除“硬件类别

如何对与标签匹配的所有产品页面应用过滤器？下面的代码将此代码应用于商店中的所有商店页面商品，但不适用于当前客户的链接产品页面，而不会覆盖其他客户视图。

add_filter( 'woocommerce_loop_add_to_cart_link', 'replacing_add_to_cart_button', 10, 2 );
function replacing_add_to_cart_button( $button, $product  ) {
    $button_text = __("Check Coverage", "woocommerce");
    $button = '<a class="button" href="******/coverage">' . $button_text . '</a>';
    return $button;
}

任何指导，批评或想法都会受到赞赏。

编辑-我使用的Ajax代码：

在子主题中从functions.php排队的jQuery脚本：

jQuery.ajax({
    type: "POST",
    url: "/wp-admin/admin-ajax.php",
    data: {
        action: 'dynamic_product_links',
        // add your parameters here
        cat1: localStorage.getItem("cat1"),
        cat2: localStorage.getItem("cat2"),          
    },
    success: function (output) {
        console.log(output);
    }
});

functions.php

add_action('wp_enqueue_scripts', 'woocommerce_ajax_check_coverage_js', 99);
function woocommerce_ajax_check_coverage_js(){

    //echo "<script type='text/javascript'>alert('called woocommerce_ajax_check_coverage_js ');</script>";
    wp_register_script( 'woocommerce-ajax-check-coverage-js', get_stylesheet_directory_uri() . "/assets/ajax-check-coverage.js", array('jquery'), null, true );
    wp_enqueue_script('woocommerce-ajax-check-coverage-js');
}

// register the ajax action for authenticated users
add_action('wp_ajax_dynamic_product_links', 'dynamic_product_links');

// register the ajax action for unauthenticated users
add_action('wp_ajax_nopriv_dynamic_product_links', 'dynamic_product_links');
function dynamic_product_links() {
    // ajax data received from jQuery script which retrieves data from local storage
    $cat1_speed = $_REQUEST['cat1']; // can be either 'Check Coverage','No Coverage' or a number linked to  a custom atttribute
    $cat2_speed = $_REQUEST['cat2'];

    if ($cat1_speed == 'check ooverage' || $cat2_speed == 'check coverage') {
        // set all matching categories except hardware to check coverage
    }
    if ($cat1_speed == 'No Coverage' ) {
        // remove this catogory item set from the store (hide?) -> change any product/* pages add to cart button to "register your interest"
    }
    if ($cat1_speed == '20' || $cat2_speed == 'check coverage') {
        // remove this catogory item set from the store (hide?) if the products atttribute is greater than the number
    }

    // in the end, returns success json data
    wp_send_json_success([/* some data here */$wireless_speed ,$fusion_fibre_speed]);

    // or, on error, return error json data
    wp_send_json_error([/* some data here */]);
}

Answer 1

要排除产品类别，请尝试使用以下之一：

1）直接处理产品类别（无父项）：

add_filter( 'woocommerce_loop_add_to_cart_link', 'replacing_add_to_cart_button', 10, 2 );
function replacing_add_to_cart_button( $button, $product  ) {
    if( ! has_term( array('hardware'), 'product_cat', $product->get_id() ) ) {
        $button_text = __("Check Coverage", "woocommerce");
        $button = '<a class="button" href="******/coverage">' . $button_text . '</a>';
    }
    return $button;
}

2）产品类别处理（以及父条款）：

add_filter( 'woocommerce_loop_add_to_cart_link', 'replacing_add_to_cart_button', 10, 2 );
function replacing_add_to_cart_button( $button, $product  ) {
    if( ! has_product_categories( $product->get_id(), array('hardware') ) ) {
        $button_text = __("Check Coverage", "woocommerce");
        $button = '<a class="button" href="******/coverage">' . $button_text . '</a>';
    }
    return $button;
}

// Custom conditional function that checks for parent product categories
function has_product_categories( $product_id, $categories ) {
     // Initializing
    $parent_term_ids = $categories_ids = array();
    $taxonomy        = 'product_cat';

    // Convert categories term names and slugs to categories term ids
    foreach ( $categories as $category ){
        if( is_numeric( $category ) ) {
            $categories_ids[] = (int) $category;
        } elseif ( term_exists( sanitize_title( $category ), $taxonomy ) ) {
            $categories_ids[] = get_term_by( 'slug', sanitize_title( $category ), $taxonomy )->term_id;
        }
    }

    // Loop through the current product category terms to get only parent main category term
    foreach( get_the_terms( $product_id, $taxonomy ) as $term ){
        if( $term->parent > 0 ){
            $parent_term_ids[] = $term->parent; // Set the parent product category
            $parent_term_ids[] = $term->term_id; // (and the child)
        } else {
            $parent_term_ids[] = $term->term_id; // It is the Main category term and we set it.
        }
    }
    return array_intersect( $categories_ids, array_unique($parent_term_ids) ) ? true : false;
}

代码进入您的活动子主题（或活动主题）的function.php文件中。经过测试，可以正常工作。
