woocommerce中覆盖的产品搜索代码不起作用

Question

我正在尝试修改产品搜索表单以包含 3 个“选择字段”而不是默认文本框。根据选择的选项（这些选项是从我添加到每个产品的自定义属性中填充的），搜索应该返回给我相关的产品。 以下是我放置在 mystile 主题文件夹中以覆盖默认搜索的“product-searchform.php”代码。我得到所有的帖子（产品）而不是具体的。所以在某个地方我的搜索不正确。还有 get_search_query() 函数的代码在哪里？

<form role="search" method="get" id="searchform" action="<?php echo esc_url( home_url( '/'  ) ); ?>">
<div>
            <!-- Default Markup
            <label class="screen-reader-text" for="s"><?php _e( 'Search for:', 'woocommerce' ); ?></label>
            <input type="text" value="<?php echo get_search_query(); ?>" name="s" id="s" placeholder="<?php _e( 'Search for products', 'woocommerce' ); ?>" />
            <input type="submit" id="searchsubmit" value="<?php echo esc_attr__( 'Search' ); ?>" />
            <input type="hidden" name="post_type" value="product" />
            */-->
<?php 
$terms = get_terms("pa_country");
$count = count($terms);
if($count > 0){
    echo '<select class="select" id="destination" tabindex="11" name="destination">';
    echo '<option value="Destination">--Destination--</option>';
    foreach($terms as $term ){
        echo '<option value="' . $term->name . '">' . $term->name . '</option>';
    }
    echo '</select>';
}

$terms = get_terms("pa_days");
$count = count($terms);
if($count > 0){
    echo '<select class="select" id="days" tabindex="11" name="days">';
    echo '<option value="Days">--Days--</option>';
    foreach($terms as $term ){
        echo '<option value="' . $term->name . '">' . $term->name . '</option>';
    }
    echo '</select>';
}

$terms = get_terms("pa_budget");
$count = count($terms);
if($count > 0){
    echo '<select class="select" id="budget" tabindex="11" name="budget">';
    echo '<option value="Budget">--Budget--</option>';
    foreach($terms as $term ){
        echo '<option value="' . $term->name . '">' . $term->name . '</option>';
    }
    echo '</select>';
}
?>
<input type="submit" id="searchsubmit" value="<?php echo esc_attr__( 'Search' ); ?>" />
<input type="hidden" name="post_type" value="product" />
</div>

<form role="search" method="get" class="woocommerce-product-search" action="<?php

    <!-- Dropdown Product Category -->

        <?php

    } else {
        $optsetlect = 0;
    }
    $args             = array(
        'show_option_all' => esc_html__('All Categories', 'woocommerce'),

        'class' => 'cat',
        'echo' => 1,

        'selected' => $optsetlect

    $args['taxonomy'] = 'product_cat';
    $args['name']     = 'product_cat';
    $args['class']    = 'cate-dropdown hidden-xs';
    wp_dropdown_categories($args);
