需要创建一个操作挂钩“woocommerce\\u account\\u[myendpoint]\\u endpoint”：

add_action(\'woocommerce_account_\' . $endpoint . \'_endpoint\', \'my_endpoint_content\');

function my_endpoint_content() {
    //content goes here
    echo \'My content goes here\';
}

因此，将几个不同的来源放在一起，要向Woocommerce我的帐户仪表板添加一个新的菜单项，需要如下内容：

    <?php

add_filter(\'woocommerce_account_menu_items\', \'add_my_menu_items\');

function add_my_menu_items($items) {
    $my_items = array(\'2nd-item\' => __(\'2nd Item\', \'[my_plugin]\'),);
    $my_items = array_slice($items, 0, 1, true) +
            $my_items +
            array_slice($items, 1, count($items), true);
    return $my_items;
}

//so, for...
$endpoint = \'2nd-item\';

add_action(\'init\', \'my_custom_endpoint\');

function my_custom_endpoint() {
    add_rewrite_endpoint(\'2nd-item\', EP_ROOT | EP_PAGES);
}

add_action(\'woocommerce_account_\' . $endpoint . \'_endpoint\', \'my_endpoint_content\');

function my_endpoint_content() {
    //content goes here
    echo \'My content goes here\';
}

add_filter(\'query_vars\', \'my_custom_query_vars\', 0);

function my_custom_query_vars($vars) {
    $vars[] = \'2nd-item\';
    return $vars;
}

add_action(\'wp_loaded\', \'my_custom_flush_rewrite_rules\');

function my_custom_flush_rewrite_rules() {
    flush_rewrite_rules();
}
