问题描述

嗨朋友们!!



我的php代码运行良好，我的本地主机没有任何错误，但没有在服务器上运行!!

它显示错误我使用php的mysqli_numrows（），mysqli_fetchrows（）等，它显示这样的错误

警告：mysqli_num_rows（）期望参数1是mysqli_result，布尔值在/ home / maxdudes / public_html中给出第97行/gujaratraksha.in/index.php



警告：mysqli_fetch_row（）要求参数1为mysqli_result，在/ home / maxdudes / public_html / gujaratraksha中给出布尔值第131行.in / index.php



警告：mysqli_fetch_row（）要求参数1为mysqli_result，在/home/maxdudes/public_html/gujaratraksha.in中给出布尔值第136行/index.php



我的代码在这里

$last_date = "SELECT SrNo,Upload_Date from photo_upload WHERE SrNo='$rows'";
$query_date = mysqli_query($con,$last_date);

$last_inserted_date = mysqli_fetch_row($query_date);
echo $last_inserted_date[1];

$sql = "SELECT Img_Location from photo_upload WHERE Upload_Date = '$last_inserted_date[1]'";
$query = mysqli_query($con,$sql);
