我有一个自定义标签搜索功能，允许人们搜索多个标签以返回相关帖子。表示他们希望看到标记为“Wordpress”和“Tutorials”的帖子。我正在使用template_include 过滤器，如下所示：

public static function template_redirect( $template ) {
    if( isset($_GET[\'tag-search\']) )
    {
        $template = locate_template( array(
            \'search.php\',
            \'archive.php\',
            \'index.php\'
        ));
    }
    return $template;
}

thetag-search 变量保存分类法的名称，我检查它是否已设置，从而指示正在执行搜索。

在这一点上template 解析为搜索。php，就像它应该的那样。所以这很好。

在pre_get_posts 操作I添加atax_query 要将返回的帖子修改为仅选定的标签，我设置is_search 为真，以及is_home 为false。这是我的pre_get_posts 措施：

public static function pre_get_posts($query) {
    if( !isset($_GET[\'tag-search\']) || !isset($_GET[\'terms\'])  ) return $query;

    if( strtolower( $_GET[\'method\'] ) == \'and\' )
    {
        $query->set( \'tax_query\', array(
            array(
                \'taxonomy\' => $_GET[\'tag-search\'],
                \'field\' => \'slug\',
                \'terms\' => explode(\',\', $_GET[\'terms\']),
                \'operator\' => \'AND\'
            )
        ) );
    }
    else
    {
        $query->set( \'tax_query\', array(
            array(
                \'taxonomy\' => $_GET[\'tag-search\'],
                \'field\' => \'slug\',
                \'terms\' => explode(\',\', $_GET[\'terms\'])
            )
        ) );
    }
    $query->is_search = true;
    $query->is_home = false;
    return $query;
}

然而，当我执行搜索时，body类是“home”，所有is_home 和is_front_page 条件是true, 他们不应该这样，因为我只是特别声明我希望这是一个搜索模板，对吗？

我知道这是可以做到的-当我添加&s 对于查询字符串，它按其应该的方式工作-尽管这样有点难看。有什么见解吗？

public static function pre_get_posts($query)
{
    $data = filter_input_array(INPUT_GET, array(
        \'tag-search\' => FILTER_SANITIZE_STRING,
        \'terms\'      => FILTER_SANITIZE_STRING,
        \'method\'     => FILTER_SANITIZE_STRING,
    ));
    if( $query->is_main_query() && !empty($data[\'tag-search\']) && !empty($data[\'terms\']) ) {
        $query->init(); // this resets ALL vars
        $query->is_search = true;
        // set tax query array
        $tax_query = array(
            \'taxonomy\' => $data[\'tag-search\'],
            \'field\'    => \'slug\',
            \'terms\'    => explode(\',\', $data[\'terms\']),
        );
        // is AND method?
        if( strtolower( $data[\'method\'] ) === \'and\' ) {
            $tax_query[\'operator\'] = \'AND\';
        }
        // set tax query
        $query->set( \'tax_query\', array($tax_query) );
    }
}

public static function pre_get_posts($query) {
    if( !isset($_GET[\'tag-search\']) || !isset($_GET[\'terms\'])  ) return $query;
        if ( ! is_admin() && $query->is_main_query() ) {
        if( strtolower( $_GET[\'method\'] ) == \'and\' )
        {
            $query->set( \'tax_query\', array(
                array(
                    \'taxonomy\' => $_GET[\'tag-search\'],
                    \'field\' => \'slug\',
                    \'terms\' => explode(\',\', $_GET[\'terms\']),
                    \'operator\' => \'AND\'
                )
            ) );
        }
        else
        {
            $query->set( \'tax_query\', array(
                array(
                    \'taxonomy\' => $_GET[\'tag-search\'],
                    \'field\' => \'slug\',
                    \'terms\' => explode(\',\', $_GET[\'terms\'])
                )
            ) );
        }
        $query->set(\'s\', \'\' );
        $query->is_search = true;
        $query->is_home = false;
    }
    return $query;
}
