Undefined valuable

in get_school method you are returning object of row objects, you need to fetch only one row. 
update your method:

PHP Code:

public function get_school() {
   $query = $this->db->query("SELECT sname FROM setting");
if($query){
 return $query->row();
}
  return false; //or return empty array
} 


use print_r or var_dump functions for debugging your code

hey any other suggestion, am really stack

send us your settings table picture.

you can connect to your db using mysql workbench connect to your db and then send us view of your settings table

Are you new to CodeIgniter? I can understand not knowing where things go.

What Insite posted has instructions. You place that code into a new helper file (or existing if you want). You have to load that helper or add it to the autoloader. Then you call it like you did with var_dump except using varDebug.

Here is a nice method to format var_dump values.

PHP Code:

/**
 * varDebug Helper - place in a helper file.
 * 
 * Formats the output of var_dump();
 * 
 */
if ( ! function_exists('varDebug'))
{
    /**
     * Debug Helper
     * ----------------------------------------------------------------------------
     * 
     * Outputs the given variable(s) with color formatting and location
     * 
     * UUSAGE: varDebug(array);
     *
     * @param    mixed    - variables to be output
     */
    function varDebug()
    {
        list($callee) = debug_backtrace();

        $arguments = func_get_args();

        $total_arguments = func_num_args();

        echo '<div><fieldset style="background: #fefefe !important; border:1px red solid; padding:15px">';
        echo '<legend style="background:lightgrey; padding:5px;">'.$callee['file'].' @line: '.$callee['line'].'</legend><pre><code>';

        $i = 0;
        foreach ($arguments as $argument)
        {
            echo '<strong>Debug #'.++$i.' of '.$total_arguments.'</strong>: '.'<br>';
            var_dump($argument);
        }

        echo "</code></pre></fieldset><div><br>";
        exit;
    }
} 


Will make it easier to read in the forum's hers.

bro i don't understand how to use your function...

You just pass the array into it just like var_debug, place the method into a CodeIgniter helper file and autoload it,
then just call it like any other method varDebug(your_array or query);

What did you Try? What did you Get? What did you Expect?

Well guys thanks I got it to work
changed this 

PHP Code:

public function get_school()
     {
         $this->db->select('*');
         $this->db->from('setting');
         return $this->db->get()->result_array();
     } 


 to 

PHP Code:

function get_school($id) {
        $compress = array();
        $query = $this->db->get('setting');
        foreach ($query->result() as $row) {
            $compress[$row->fieldoption] = $row->value;
        }
        return (object) $compress;
    }
