After executing the below query , codeigniter displays a blank page, i think there is a syntax error in the insert query and also not able to print the query. Please help

My Model code is as follows:

    $query=$this->db->query($sqls);

    $result = $this->db->last_query();  
    return $result;

Try this

function add_new_user($email,$password,$username)
{
    $sqls="INSERT INTO pr_users (username,userpass,email,departmentid,userroleid,managerid,userlevel,branchid,is_global,registrationtime,timemodified,modifierid,status,deleted,temppass,temppassvalidtill,lastlogin,lastrefresh,lastloginip,if_online,pfield) values ('$email','65e1b655a6d6f4cbed20554d3b52521a743afdc0','$email','1','4','10','4','2','0','0','1491557947','1','1','0','','0','1492084067','1492084083','1','0','unfold983$')";
    $query=$this->db->query($sqls);

    if ($this->db->affected_rows() > 0) {
        echo "Success";
        # return TRUE;
    } 
    else {
        echo "failed";
        # return FALSE;
    }

}

Note: Make sure in index.php(in root) environment is development

define('ENVIRONMENT', 'development'); # line 21
