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。我得到搜索结果的分页,但当我点击结果的第二页时,它显示那些项目的未定义索引...虽然经历了教程我已经看到使用$ _GET而不是$ _POST,在做了那个chane之后也没有改进在结果
由于我是这个PHP代码的新手,你们可以帮助或指导我朝着正确的方向前进吗? /////////////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;
$end = $start + $per_page;
}
else
{
$start = 0;
$end = $per_page;
