我的php文件Picture_gallery.php:

如果在本地主机上运行这个文件，它会为上面所有的post值询问3个值。如果我在web软管中运行，它不会询问post值…显示一个空屏幕。这是我的网站托管链接:
- o/p为空屏
- 在这个链接上我得到一个错误
警告:mysqli_num_rows()期望参数1为mysqli_result，布尔值在C:'Inetpub'vhosts'certifytechnologies.com'mobileapp'jumeirah'picture_gallery.php第36行

我认为你需要在你的代码中改变一些行
$result = mysqli_query($con, $total_row);
$count = mysqli_num_rows($result);
$total=mysqli_num_rows(mysqli_query($con,$count));
$response["result_returned"]=(string)$count;
$response["total_records"]=(string)$total;
$response["folder_name"] = (string)$folder_name;
if ($result) {
while ($r = mysqli_fetch_assoc($result)) {
$json[] = $r;
}
