// 获取当前帖子的类别
$categories = get_the_category();

// 遍历类别数组
foreach ($categories as $category) {
    // 获取类别ID
    $category_id = $category->cat_ID;

    // 根据类别ID获取对应的图像URL
    switch ($category_id) {
        case 1:
            $image_url = 'https://example.com/image1.jpg';
            break;
        case 2:
            $image_url = 'https://example.com/image2.jpg';
            break;
        // 添加更多的类别和对应的图像URL
        default:
            $image_url = 'https://example.com/default.jpg';
            break;
    }

    // 获取附件图像的数组
    $attachment_image = wp_get_attachment_image_src($attachment_id);

    // 更新图像URL
    $attachment_image[0] = $image_url;

    // 输出图像URL
    echo $attachment_image[0];
