PHP MySQL的插入更新查询在本地工作，但不能在服务器上工作

Question

All kind of mysql queries working on locally, but when i try to run the insert and update queries from a php page on live server, it does not work and doesn't show any kind of error. My database connection is ok. I can fetch data from database. But i can't insert new data or update existing data from a php page.

Here is one of my queries:

<?php

session_start();
if(empty($_SESSION['UserId'])){
    header("Location: index");
    die();
}
include("utility.php");

if(isset($_POST["btnEdit"]))
{
    $memberName = $_POST["memberName"];
    $designation = $_POST["designation"];

    $memberDetails = '';
    if(isset($_POST["memberDetails"])){
        $memberDetails = $_POST["memberDetails"];
    }
    $memberEmail = '';
    if(isset($_POST["memberEmail"])){
        $memberEmail = $_POST["memberEmail"];
    }

    $linkedin = '';
    if(isset($_POST["linkedin"])){
        $linkedin = $_POST["linkedin"];
    }

    $teamId = $_POST["teamId"];

    $result=mysqli_query($conn,"UPDATE team SET  memberName='".$memberName."', designation='".$designation."', memberDetails='".$memberDetails."', memberEmail='".$memberEmail."', linkedin='".$linkedin."' WHERE teamId='".$teamId."'");

    header("Location:team_member_list?id=".$teamId."&msg=Member Updated Successfully...)");
}
?>

Can someone kindly tell me what may be the reason?

Answer 1

You can try to run those update/insert queries directly by manualy connecting to database and look for errors. But first, as devnull Ψ sad before, check your database user permissions.
