搜索结果的分页问题

我正在尝试对搜索结果进行分页，这是我用来从用户表单中查找搜索查询的代码。我正在对搜索结果进行分页，但是当我单击结果的第 2 页时，它显示发布的那些项目的未定义索引...虽然通过教程我看到使用 $_GET 而不是 $_POST ，但在这样做之后也没有改善结果

由于我是这个 php 代码的新手，你们能帮助或指导我正确的方向吗？////////////test.php//////////////// 

    mysqli_report(MYSQLI_REPORT_ERROR);


    // number of results to show per page
    $per_page = 2;

    // figure out the total pages in the database
    if ($result = $mysqli->query("SELECT * FROM bridegroom where Gender like '%$Name%' and Castest like'%$caste%' and Location like '%$location%' order by AGE"))
    {
        if ($result->num_rows != 0){
            $total_results = $result->num_rows;
            // ceil() returns the next highest    integer value by rounding up value if necessary
            $total_pages = ceil($total_results / $per_page); 
            if (isset($_GET['page']) && is_numeric($_GET['page']))
            {
                $show_page = $_GET['page'];
                if ($show_page > 0 && $show_page <= $total_pages)
                {
                   $start = ($show_page -1) * $per_page;
