Custom Code conversion from mySQL to mySQLI

You are missing the: ->getColumnVal portion in several places. I think it should be:

<a href="<?php echo $serverDomain.'/hotpage/home/'.strtolower(str_replace(' ', '-', trim($SecurityAssisttbldirectorylistings->getColumnVal('businessname'))) . '.' . strtolower(str_replace(' ', '-', trim($SecurityAssisttbldirectorylistings->getColumnVal('firstname'))) . '.' . strtolower(str_replace(' ', '-', trim($SecurityAssisttbldirectorylistings->getColumnVal('lastname'))) . '.' .($SecurityAssisttbldirectorylistings->getColumnVal("id")); ?>"><img src="<?php echo($SecurityAssisttbldirectorylistings->getColumnVal("logo_img")); ?>"></a>
