Im making a cron job and currently it diplays the result correctly but when it needs to update it fails.
Anyone have any ideas

PHP Code:
<?php


//phpinfo();
$mysqli = new mysqli('-','-','-'"-");

/* check connection */
if (mysqli_connect_errno()) {
    
printf("Connect failed: %s\n"mysqli_connect_error());
    exit();
}


$result2 "SELECT * FROM tblJobs order by DatePosted desc";
$result mysqli_query($mysqli$result2)
or die(
'Error querying database.');


while(
$row mysqli_fetch_array($result))
  {
    
    
$time strtotime($row['DatePosted']);
$one_week_ago strtotime('-30 days');

if( 
$time $one_week_ago ) { 

    
}else{

echo 
"<td>needs hiding</td>";    
$tempff $row['JobID'];

$update "UPDATE tblJobs SET Show = 0 WHERE JobID = ".$row['JobID']."";
$result mysqli_query($mysqli$update);
    
}


  }




?>
