hi, I tried to change update query from mysql to mysqli, at first under mysql is works great to update into mysql database but when i changed to mysqli is not doing update it. can anyone tell me what did i missed!
 
under mysql
 
<?php
include('db.php');
if(isset($_GET['status']))
{
$status1=$_GET['status'];
$select=mysql_query("select * from manage where id='$status1'");
while($row=mysql_fetch_object($select))
{
$status_var=$row->status;
if($status_var=='0')
{
$status_state=1;
}
else
{
$status_state=0;
}
$update=mysql_query("update manage set status='$status_state' where id='$status1' ");
if($update)
{
header("Location:index.php");
}
else
{
echo mysql_error();
}
}
?>
<?php
}
?>
 
 
and under mysqli
 
<?php
include('db.php');
$dbcs = new mysqli($mysql_hostname, $mysql_user, $mysql_password, $mysql_database);
if(isset($_GET['status']))
{
$status1=$_GET['status'];


  $sql = "select * from product where product_id='$status1'";
  $result=mysqli_query($dbcs,$sql);


while($row=mysqli_fetch_object($result))
{
$status_var=$row->status;
if($status_var=='0')
{
$status_state=1;
}
else
{
$status_state=0;
}


$mysqli->query("UPDATE product set status='$status_state' where product_id='$status1' ");
if($mysqli)
{
header("Location:item.php");
}
else
{
echo mysqli_error();
}
}
?>
<?php
}
?>

Find your php.ini and set

error_reporting = -1
display_errors = on
restart your web server, and try your script.

 

Hint: a problem (there may be others I didn't see at a glance) is with

$mysqli->query("UPDATE product set status='$status_state' where product_id='$status1' ");

i'm going to guess you are not seeing any php errors because you are not requesting the page with a ?status=n on the url and most of the logic is being skipped over. you might also have output_buffering turned on in your php.ini and any output from php or your code is being discard.

 

 

btw - to toggle a value between back and forth between zero and one, you don't need all that logic -

include 'db.php';
$mysqli = new mysqli($mysql_hostname, $mysql_user, $mysql_password, $mysql_database);

if($mysqli->connect_error){
    die("Connect Error ($mysqli->connect_errno) $mysqli->connect_error");
}

$status = isset($_GET['status']) ? (int)$_GET['status'] : false;
if($status)
{
    if(!$mysqli->query("UPDATE product set status = NOT status where product_id=$status")){
        die("Query failed: $mysqli->error");
    }
    header("Location:item.php");
}
