我终于成功了。

找到这个post 这与我的任务有关。

根据这一点，首先，我们必须通过放置隐藏输入来编辑搜索表单。根据需要为输入命名。以及使用javascript更改表单提交时的输入值。

<input type=”hidden” name=”search_type” value=”site-search” />

其次，搜索。必须用以下代码替换为搜索结果创建的php或任何其他页面模板。通过设置控制隐藏输入值的条件，并相应地加载相关模板。

<?php
$search_refer = $_GET[“search_type”];
if ($search_refer == ‘icon - packs’) {
    load_template(TEMPLATEPATH . ‘ / pack - search . php’);
} elseif ($search_refer == ‘icons’) {
    load_template(TEMPLATEPATH . ‘ / icons - search . php’);
};
?>

为了在分类法中进行搜索并在搜索结果页面中将它们作为结果列出，我使用了一些wp query和其他相关功能，并创建了这个用于显示它们的自定义函数。

1） 功能。php-我创建了一个函数，将搜索到的短语和分类名称发送给它，它返回一个自定义分类的术语数组。

// We get a list taxonomies on the search box
function getTaxBySearch($search_text,$tax_name){

    $args = array(
        \'taxonomy\'      => \'icon_package\', // taxonomy name
        \'orderby\'       => \'id\', 
        \'order\'         => \'ASC\',
        \'fields\'        => \'all\',
        \'name__like\'    => $search_text
    ); 
    
    $terms = get_terms( $args );
    $count = count($terms);
    if($count>0){
        return $terms;
    }else{
        return 0;
    }
    
    }

最后，为每种搜索类型（图标、图标包）制作搜索结果页面模板

<?php get_header(); ?>

<?php $terms = getTaxBySearch($args[\'searched_phrase\'], \'icon_package\'); ?>

<?php if ($terms > 0) : ?>
    <div class="icons-search__container">
        <div class="icons-header">
            <h1> Free SVG Flat Icon Packs</h1>
            <p></p>
        </div>
        <div class="item-grid-masonry" data-controller="item-grid--masonry" data-item-grid--masonry-has-masonry-value="true" data-item-grid--masonry-scrollbar-fix-value="true" style="height: 3555px;">

            <?php foreach ($terms as $term) : ?>
                <?php $term_url = get_term_link($term->term_id, \'icon_package\'); ?>
                <?php $term_by_id = get_term($term->term_id, \'icon_package\'); ?>
                <div class="item-grid-item" style="width: 461px; transform: translate3d(0px, 0px, 0px);">
                    <div class="icon-pack-card" style="--color-bg: #e3e9e7">
                        <a class="icon-pack-card__link" href="<?php echo $term_url; ?>" aria-label="Link to item page">
                            <div class="icon-pack-card__header">

                                    <?php $term->name; ?>
                                </div>
                                <div class="icon-pack-card__count">
