I installed a fresh google VM and getting odd errors on a common mysql command I use. The query works fine from shell but from the browser I get 500 error.

[Thu Apr 06 20:30:37 2017] [error] [client] PHP Fatal error:  Call to a member function fetch_assoc() on a non-object in /var/www/html/myfile.php on line 21

The issue is most likely in my server setup. I installed php using yum.


$linkID5 = new mysqli('hostname', 'user', 'password', 'database');

        $tbl_name = "query_table_" . $_REQUEST['qbID'];
        //print "$tbl_name<br>";

        if ($_REQUEST['confirmed_lead'] == "yes") {
                $ts = date("U");
                $sql = "UPDATE `$tbl_name` SET `confirmed_lead` = 'yes',`confirmed_timestamp` = '$ts' WHERE `xxLeadId` = '$_REQUEST[xxLeadID]'";
                $result = $linkID5->query($sql);
        } else {
                // get columns
                $sql = "SHOW Columns FROM `$tbl_name` WHERE `Field` NOT IN ('id','date','system_timestamp','system_reposted')";
                $result = $linkID5->query($sql);
                $sql_top = "";
                $sql_bot = "";
                $date = date("Y-m-d H:i:s");
                $system_timestamp = date("U");
                while ($row = $result->fetch_assoc()) {
                        $field = $row['Field'];
                        $sql_top .= "`$row[Field]`,";
                        $sql_bot .= "'".$_REQUEST[$field]."',";
                $sql_top .= "`date`,`system_timestamp`,`system_reposted`";
                $sql_bot .= "'$date','$system_timestamp','No'";

                $sql = "INSERT INTO `$tbl_name` ($sql_top) VALUES ($sql_bot)";
                //print "SQL: $sql";
                $result = $linkID5->query($sql);


This same code works on other servers just fine.
