用户元数据的Ajax分页

这是我的AJAX脚本：

function nanny_search_ajax1() {
$search_in = $_POST['search_in'];
$search_type = $_POST['search_type'];
$start_date = $_POST['start_date'];
$keyword = $_POST['keyword'];


if($search_in=='nanny'){
    $search_in ='interested';
}
else{
    $search_in ='lookgin';
}

$start_value = $start_date;
$start_compare = '=';


$nanny_result = '';
$nanny_error = '';


$number     = 2; 
$paged      = (get_query_var('paged')) ? get_query_var('paged') : 1;
$offset     = ($paged - 1) * $number;

$args = array(
    'meta_query' => array(
        'relation' => 'AND',array(
            'key' => 'user_start','value' => $start_value,'compare' => $start_compare
            )
        ),'offset'=>$offset,'number'=>$number,);


$users      = get_users();
$query      = get_users($args);
$total_users = count($users);
$total_query = count($query);
$total_pages = intval($total_users / $number) + 1;


$query = get_users($args);



if (!empty($query)) {
    foreach ($query as $user) {
        $profile_picture = wp_get_attachment_url(get_user_meta($user->ID,'be_custom_avatar',true));
        $profile_picture = get_avatar($user->ID,100);
        if($search_in=='nanny'){
            $interested = get_user_meta($user->ID,'interested',true);
        }
        else{
            $interested = get_user_meta($user->ID,'lookgin',true);
        }

        $user_date = get_user_meta($user->ID,'user_start',true);
