Redirect to same page with error message - Joomla! Forum - community, help and support

when delete record db, if have error model has following code:

code: select all

$query = "delete #__tbl id in (".implode(',', $arrayids).")";
                   $db = $this->getdbo();
                   $db->setquery($query);
                   if (!$db->query()){
                            $errormessage = $this->getdbo()->geterrormsg();
                            jerror::raiseerror(500, 'error deleting tenders: '.$errormessage);
                   }


the jerror::raiseerror method displays page in attached picture. so, don't want page displayed way instead want redirected page submitted before , error displayed somewhere in top of page. how achieve this?

hi,
in controller:

code: select all

$model=$this->getmodel();
$ermsg=$model->somefunc();
$this->setredirect('index.php?...',$ermsg);
