Undefined valuable

@neuron  

when i use your code

PHP Code:

public function get_school() {
        $query = $this->db->query("SELECT sname FROM setting");
        if($query){
            return $query->result();
        }
        return false;
    } 


and dump
 

PHP Code:

<?=var_dump($schoolTitle)?>

 i get bool(false)

but when i change 
$query = $this->db->query("SELECT sname FROM setting");
to
$query = $this->db->query("SELECT * FROM setting");

and dump again, I get all the results

so when i try to retrieve <h1><?php echo $schoolTitle->sname?></h1> 
i get the following error...

A PHP Error was encountered
Severity: Notice
Message: Undefined index: sname
Filename: mark/view.php
Line Number: 23
