问题是，当我将查询发送到数据库时，它正在更改我的数组级别，而不是“s”值不为空，因此它阻止了我的记录被提取，第三个也是最重要的问题是我通过更改函数进行查询的方式解决了我的问题。

以下是此逻辑的更新代码，以防其他人需要实现此类功能。

The main function where all the data is gathering up and making a query

public function pre_get_posts($q) {

    // check if the user is requesting an admin page 
    if (is_admin() || !$q->is_main_query())
        return;

    if (!is_post_type_archive(\'auto-listing\'))
        return;

    if (!is_search())
        return;

    $meta_query = array();

    $year_query[] = $this->year_query();
    $model_query[] = $this->model_query();
    $condition_query[] = $this->condition_query();
    $odometer_query[] = $this->odometer_query();
    $price_query[] = $this->price_meta_query();
    $body_type_query = $this->body_type_query();
    $country_query = $this->country_query();
    $transmission_query = $this->transmission_query();
    $radius_query[] = $this->radius_query($q);

    $query_1 = array_merge($country_query, $year_query, $model_query, $condition_query, $price_query, $odometer_query, $transmission_query);
    // if our radius query fails, fall back to keyword searching
    // will fail with no map API key
    if (empty($radius_query[0]) || !$radius_query[0]) {
        $keyword_query[] = $this->keyword_query($q);
        $query_2 = $keyword_query;
    } else {
        $query_2 = $radius_query;
    }

    // if no keyword
    if (empty($_GET[\'s\'])) {
        $query_1[\'relation\'] = \'AND\';
        $meta_query[] = $query_1;
    }

    // if keyword
    if (!empty($_GET[\'s\'])) {
        $query_2[\'relation\'] = \'OR\';
        $meta_query[] = $query_1;
        $meta_query[] = $query_2;
        $meta_query[\'relation\'] = \'AND\';
    }

    $q->set(\'meta_query\', $meta_query);

    $q->set(\'tax_query\', $body_type_query);

    $q->set(\'post_type\', \'auto-listing\');

}

Radius query function that was actually doing the magic

public function radius_query($q) {

    if (isset($_GET[\'s\']) && !empty($_GET[\'s\'])) {

        $searchterm = isset($q->query_vars[\'s\']) ? sanitize_text_field($q->query_vars[\'s\']) : \'\';

        // we have to remove the "s" parameter from the query, because it will prevent the posts from being found
        $q->query_vars[\'s\'] = \'\';

        if ($searchterm != \'\') {

            $search_radius = $this->geocode($searchterm);

            if (!$search_radius)
                return false;

            $lat = $search_radius[\'lat\']; // get the lat of the requested address
            $lng = $search_radius[\'lng\']; // get the lng of the requested address
            // we\'ll want everything within, say, 30km distance
            $distance = isset($_GET[\'within\']) && !empty($_GET[\'within\']) ? floatval($_GET[\'within\']) : 0.1;

            // earth\'s radius in km = ~6371
            $radius = auto_listings_metric() == \'yes\' ? 6371 : 3950;

            // latitude boundaries
            $maxlat = $lat + rad2deg($distance / $radius);
            $minlat = $lat - rad2deg($distance / $radius);

            // longitude boundaries (longitude gets smaller when latitude increases)
            $maxlng = $lng + rad2deg($distance / $radius / cos(deg2rad($lat)));
            $minlng = $lng - rad2deg($distance / $radius / cos(deg2rad($lat)));

            // build the meta query array
            $radius_array = array(
                \'relation\' => \'AND\',
            );

            $radius_array[] = array(
                \'key\' => \'_al_listing_lat\',
                \'value\' => array($minlat, $maxlat),
                \'type\' => \'DECIMAL(10,5)\',
                \'compare\' => \'BETWEEN\',
            );
            $radius_array[] = array(
                \'key\' => \'_al_listing_lng\',
                \'value\' => array($minlng, $maxlng),
                \'type\' => \'DECIMAL(10,5)\',
                \'compare\' => \'BETWEEN\',
            );

            return apply_filters(\'auto_listings_search_radius_args\', $radius_array);
        }
    }
}

And now the final function that was fetching the lat and long from the zip code that user enters

private function geocode($address) {
    // url encode the address
    $address = urlencode(esc_html($address));

    // google map geocode api url
    $url = auto_listings_google_geocode_maps_url($address);

    $arrContextOptions = array(
        "ssl" => array(
            "verify_peer" => false,
            "verify_peer_name" => false,
        ),
    );

    // get the json response
    $resp_json = file_get_contents($url, false, stream_context_create($arrContextOptions));

    // decode the json
    $resp = json_decode($resp_json, true);

    //pp( $resp );
    // response status will be \'OK\', if able to geocode given address 
    if ($resp[\'status\'] == \'OK\') {

        // get the lat and lng
        $lat = $resp[\'results\'][0][\'geometry\'][\'location\'][\'lat\'];
        $lng = $resp[\'results\'][0][\'geometry\'][\'location\'][\'lng\'];

        // verify if data is complete
        if ($lat && $lng) {

            return array(
                \'lat\' => $lat,
                \'lng\' => $lng,
            );
        } else {
            return false;
        }
    } else {
        return false;
    }
}
